An Astro2010 Decadal Survey Town Hall at the NRAO

Robert Dickman

To foster community understanding of and support for the recommendations of the Astro 2010 Decadal Survey, "New Worlds, New Horizons," the NRAO and the American Astronomical Society (AAS) will host an Astro2010 Decadal Survey Town Hall on Thursday, 4 November 2010 from 1-4 p.m. MDT at the NRAO Domenici Science Operations Center on the campus of New Mexico Tech in Socorro (Directions). Astro2010 committee member Paul Vanden Bout will give a Decadal Survey presentation and answer audience questions. There will be ample time for discussion with Paul and among the attendees.

This NRAO event is part of a series of Astro2010 Town Halls being held across the US from September – November 2010. I encourage all AAS members within reasonable driving distance of the NRAO facilities in Socorro to join us for this important event. A culminating Astro2010 Town Hall will take place at the January 2011 AAS meeting in Seattle, WA.

2011 Jansky Fellowship Announcement

The National Radio Astronomy Observatory (NRAO) announces the 2011 Jansky Fellowship Program which provides outstanding postdoctoral opportunities for research in astronomy. Jansky Fellows formulate and carry out investigations either independently or in collaboration with others within the wide framework of interests of the Observatory. Prior radio experience is not required and multi-wavelength projects leading to a synergy with NRAO instruments are encouraged. The NRAO also encourages applications from candidates with interest in radio astronomy instrumentation, computation, and theory.

Appointments may be made for positions at any of these NRAO sites: Socorro, NM; Green Bank, WV; and Charlottesville, VA. As ALMA commissioning activities get underway, we anticipate that there will also be appointments available in Chile. Jansky Fellows are encouraged to spend time at universities working with collaborators during the course of their Fellowship.

In addition to appointments at NRAO sites, non-resident Jansky Fellowships may be offered for appointments that are hosted at a U.S. university. Frequent and/or long term visits to NRAO sites are encouraged. Split Fellowships with time spent at NRAO and a U.S. university are permitted.

The starting salary will be $62,000 per year with an appointment duration of two years, and possible renewal for a third. A research budget of up to $10,000 per year is provided for travel and computing requirements. Fellows are eligible for page charge support, vacation accrual, health insurance coverage, and a moving allowance. In addition, up to $3,000 per year is provided to non-NRAO institutions hosting Jansky Fellows to defray local institutional costs.

Note that the match between the host university and the candidate's research program is an important factor in the selection process. Also, appointments of more than one Jansky Fellow at a single external institution at a given time are discouraged. A list of blocked institutions for 2011 can be found below.

The purpose of the program is to provide an opportunity for young scientists to establish themselves as independent researchers so that they may more effectively compete for permanent positions. The placement of Fellows at institutions other than the NRAO will help foster closer scientific ties between the NRAO and the U.S. astronomical community. The NRAO Postdoctoral Symposium is held annually to ensure close contact among all Observatory Fellows and the NRAO.

Candidates must receive their PhD prior to beginning a Jansky Fellowship appointment.

The Jansky Fellowship application procedure is available on-line. The deadline for both applications and letters of recommendation is Monday, November 1, 2010. Award offers will be made by February 15, 2011, with the Fellowships normally expected to begin September 2011. The NRAO is an equal opportunity employer (M/F/H/V).

Registration Open for ALMA Spectroscopy Workshop

Anthony Remijan and Gerald Schieven (NRC-Canada)

Registration is open for the “ALMA: Extending the Limits of Astrophysical Spectroscopy” workshop that will be held 15 – 17 January 2011 in Victoria, British Columbia. The National Research Council of Canada (NRC), the North American ALMA Science Center (NAASC), and the Center for Chemistry of the Universe (CCU) are jointly hosting this workshop that will highlight the Atacama Large Millimeter/submillimeter Array (ALMA) capabilities and scientific opportunities that will soon be available to the community.

Abstract submission is now open and will remain open until 30 November. Meeting Registration will be limited to ~100-120 participants and will close once the maximum number has been reached. As the call for Early Science proposals with ALMA is approaching, we also invite you to attend a one-day ALMA tutorial that will include:

  • ALMA Early Science capabilities
  • The services provided by the North American ALMA Science Center
  • How to use the ALMA Observing Tool and submit a proposal
  • How to simulate an early science observation using the SIMDATA package in CASA (the data reduction package for ALMA)

The tutorial will take place directly AFTER the Spectroscopy 2011 Conference, on Tuesday, 18 January 2011 in Victoria, Canada at a cost of $100 per participant to cover the tutorial room, equipment, and refreshments. As the goal is hands-on experience with the OT and SIMDATA which uses CASA, participants will need to bring their own laptop and install (and verify they work) these packages before they arrive. The NAASC department at the NRAO helpdesk is available to address questions about installation etc, and more information about installing these packages will be forthcoming.

As venue space is limited for this event, we can only offer ~60 spaces so please register ASAP to reserve your place in the tutorial. For those interested in attending the tutorial but who are not attending the Spectroscopy 2011 meeting, registration for the tutorial ONLY is available online.. The tutorial registration will remain open until 30 November 2010, or until we reach the maximum number of participants. We sincerely hope you will consider attending this workshop and tutorial and join the community in realizing the full potential of ALMA!

Approved NRAO Science Program: Trimester 2010-C

The June 2010 Call for Proposals covered the third trimester of 2010. A total of 222 proposals were received. The GBT and the VLA/VLBA Proposal Selection Committees (PSC) met in the second week of August to review the referee rankings and technical reports for all proposals, with the goal of providing a recommended science program to the NRAO Director’s Office.

A list of the approved EVLA, VLBA/High Sensitivity Array (HSA), and GBT observing programs for Trimester 2010-C is given below. For each approved program is listed: (a) the PI’s last name; (b) the title of the approved proposal, and the total hours allocated for the program, and (d) the type of proposal (Regular or Large). In cases of Large proposals or monitoring projects the time allocated may be over more than one trimester.

Expanded Very Large Array (EVLA)

To maximize early EVLA science while simultaneously commissioning the hardware and introducing new capabilities, three separate programs were created. They are, in brief, Open Shared Risk Observing (OSRO) which provides first-light EVLA capabilities to the general user community, Resident Shared Risk Observing (RSRO) which provides access to enhanced EVLA capabilities to those who are able to spend a period of time in Socorro to help with commissioning, and a modest (<500 hrs/year) EVLA Commissioning Staff Observing (ECSO) program giving access to commissioning staff to push new science capabilities.

Joint NRAO/Chandra Program: Accepted Proposals

Dale Frail

In 2003 NRAO entered into a joint proposal process with the Chandra X-ray Center. Up to 3% of the time on all NRAO telescopes was made available per year (with no more than 5% in a single trimester). Time is awarded on a competitive basis by means of a single proposal asking for both X-ray and radio observations, and submitted to the Chandra X-ray Center. Successful US-based PI's are eligible for NASA funding. Further details of this program are available in the Chandra X-ray Center Proposal Calls.

The results of the Chandra proposal Cycle 12 have been made public. We list below the 11 successful joint NRAO/Chandra proposals for this cycle, giving the name of the principle investigator, the proposal title, and the total number of hours allocated on NRAO telescopes for each proposal. In all cases the proposals requested time on the EVLA.

A New Home for ALMA in Santiago

At the end of August, ALMA activities in Santiago moved a short distance, from their temporary quarters on the upper floors of a building in Santiago’s Los Condes ‘Sanhattan’ area to their permanent home in the Santiago Central Office on the grounds of the ESO compound in Vitacura. The building will get a workout during the upcoming austral spring as multiple reviews are held to determine ALMA readiness for the Call for Proposals for Early Science.

The first of these will be the External Review of the status of Commissioning and Science Verification that will be held at the ALMA site 7-8 October and led by Project Scientist Richard Hills. The Science Operations External Review, including the ALMA Regional Centers (ARCs), will be held in Santiago 11-12 October for a separate external committee, being arranged by Head of Science Operations Lars-Ake Nyman. The following two days the ALMA Science Advisory Committee (ASAC), a committee of the ALMA Board, will meet in Santiago to prepare a report to the Board. The third Annual ALMA External Review will be held 25-28 October. An Array Status Review on 8-9 November will focus on maintenance capabilities for hardware and software. On 10 November, an Observatory Readiness Review will be held to pull together the conclusions of the external reviews, and the recommendations of the ASAC and AAER committees, in preparation for the ALMA Board meeting 16-18 November. This ALMA Board meeting will decide the call for proposal date, the Early Science observations start date, and the Early Science capabilities to be offered. An announcement of these Board decisions is expected by the end of November.

ALMA Test Data

A small amount of ALMA test data was released in September to illustrate some of the progress being made during construction. As test data, only some aspects of the complete observation, calibration and imaging cycle have been applied to the data.

Project Scientist Richard Hills noted the challenges, among which is conducting observations in the normally opaque atmospheric bands which are available though far from transparent at the ALMA site. All aspects of the ALMA system, from antenna performance (surface, pointing with small beams, tracking accuracy) to system and atmospheric stability are tested in the high frequency bands, such as Band 9 (602-720 GHz; 0.4-0.5mm wavelength). Bright calibration sources are also scarce at these wavelengths.

The test data illustrates that ALMA's performance at the cutting edge continues to make progress--data at the 690 GHz CO line in the well-known southern galaxy NGC253 was calibrated using Jupiter's bright moons Io and Callisto. The test data shows impressive atmospheric and instrumental performance during the observation.

Halfway to the Early Science Antenna Array

ALMA continued to grow in size and capability throughout August and September, with the Transport of Vertex Antenna 8 to the high-elevation Array Operations Site (AOS) on 27 September and its incorporation into the commissioning array.

The first two antennas to reach the AOS, DV01 and PM03, are at the lower elevation Operations Support Facility (OSF) undergoing updates. DV01 returned to the Assembly, Integration and Verification area from the contractor’s site and awaits incorporation into the OSF two-station interferometer with DV09 for further tests and for software testing leading to the installation of a major software release at year-end. Antennas PM01 and PM04 have been moved to the OSF AIV area; ALMA acceptance is expected soon. DV10 is undergoing its final tests at the Vertex Site Erection Facility. Four new 7m antennas arrived from Japan. The first of the European AEM antennas passed its Technical Readiness Review and has begun pointing tests with the Optical Pointing Telescope.

As the Array moves closer to the key decision point on the timing of the issuance of the Call for Early Science, preparatory work at the ARCs has increased. An exercise testing readiness for Early Science was carried out in which participants submitted mock proposals, including helpdesk functions, participated in a load test in which over 700 mock proposals were submitted to the archive in 15 minutes, the technical and scientific assessment process for the mock proposals. Participants provided feedback at all steps in the exercise. A number of ALMA user documents were written, vetted, and submitted to Science Operations Readiness Review panel including an updated ALMA Primer, an ALMA Quickstart guide, and Early Science simulations.

The yearly ANASAC face-to-face meeting was held at the North American ALMA Science Center (NAASC) in Charlottesville, Virginia on 13-14 September. Participants considered a number of charges relating to NAASC and ALMA readiness for Early Science.

The Astro2010 Committee for a Decadal Survey of Astronomy and Astrophysics Radio Millimeter and Submillimeter panel report released on 13 August stated: ALMA will be the world’s premiere facility for high-resolution imaging at millimeter/submillimeter wavelengths. It is essential that a program of upgrades be supported to maintain its vitality. While the upgrades will be determined by agreement of the international consortium, there are some obvious examples. Some receiver bands are not included in the first light complement; adding these is important for obtaining complete wavelength coverage within atmospheric windows, which is especially needed for line studies of galaxies over the full range of redshifts. Adding capability to join the mm-wave VLBI network would greatly enhance the sensitivity for ultra-high resolution millimeter/submillimeter studies (Table 9.1). The consortium plans a program costing $90 million over a decade, of which $30 million would come from the North American partners. The panel fully supports this plan.” Support for ALMA development was also highlighted in the main report (Table B-1).

The sixth issue of the Joint ALMA Observatory newsletter (JAO) is available. This issue reports the successful demonstration of phase correction at the ALMA site via the Water Vapor Radiometer, whose role is to measure atmospheric water vapor in the line of sight of each antenna and apply corrections to the astronomical data. Learn more about this advancement and others in this JAO newsletter issue.
