VLA Sky Survey

News Update: Science Working Group discussions underway

The VLASS Science Working Groups are actively discussing the options for the survey. See our Discussion Forum page for links to the discussions. The working groups have also posted first drafts of discussion summaries on the individual public WG wikis.

News Update: Survey Science Group is Ready to Go!

The VLASS Survey Science Group is ready for you to join in the quest to define the survey. Choose to participate in one or more of the Science Working Groups through our Discussion Forums. Also, to receive announcements related to the survey, please register for the vlass-announce list.


 

Very Large ArrayIn the 20 years since the initial observations were made for the NRAO VLA Sky Survey (NVSS) and the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST), these pioneering programs have defined the state-of-the-art in centimeter radio sky surveys and produced a steady stream of excellent science. Given the enhanced capabilities of the Jansky Very Large Array (VLA), now is an appropriate time to discuss the scientific potential of new centimeter-wavelength sky surveys.

The astronomy community has already recognized that several of the high priority science goals of the 2010 decadal survey New Worlds, New Horizons in Astronomy and Astrophysics could be addressed by a new VLA sky survey. At the May 2013 Radio Astronomy in the LSST Era held at NRAO-Charlottesville, for example, many scientists expressed keen interest in employing the VLA to conduct new, wide-area centimeter wavelength sky surveys in support of multi-wavelength synoptic surveys using existing and future facilities, such as the Large Synoptic Survey Telescope (LSST).

Thus, we are announcing a NRAO VLA Sky Survey (VLASS) initiative that will explore the science and technical opportunities of a new centimeter-wavelength survey. A community-led Science Survey Group (SSG) will define the science program and key components of VLASS, and NRAO will support its technical definition and implementation. All VLASS data will be available immediately to the North American community.

Please join us for the VLASS Workshop at the AAS!

Additionally, a VLASS workshop for all interested community members is being organized directly preceding the January 2014 American Astronomical Society meeting at National Harbor, MD, on Sunday, 5 January 2014 from 10:00 AM - 4:00 PM. Stay tuned to eNews for further information.

The VLA Sky Survey Science Forum is open!

Posted 9 September 2013

We have created the VLA Sky Survey Science Forum to allow you to participate in the SSG process, and to generate, explore, and evolve ideas for the VLASS.

Call for White Papers

Posted 9 September 2013

The NRAO announces an open call for community white papers on the VLA Sky Survey (VLASS) concerning survey science goals, techniques, development areas, and overall design. Community white papers submitted for the VLASS will form the basis for discussion and presentations at the January AAS Workshop. Individuals or groups interested in attending and speaking at the workshop are strongly encouraged to submit white papers by 1 December 2013, to allow ample time for inclusion in the workshop. See the Call for VLASS White Papers link to the left for more details.

Call for SOC Nominations

Posted 26 September 2013, Updated 18 October 2013

Dear Colleague,

We are calling for nominations of individuals to serve on the Science Organizing Committee (SOC) that will guide the initial planning for the upcoming VLA Sky Survey (VLASS). The SOC will be primarily charged with review of White Papers received in response to the recent call, and with organization of the NRAO Very Large Array Sky Survey Science Planning Workshop, to be held on January 5, 2014, immediately prior to the upcoming 223rd meeting of the American Astronomical Society at National Harbor, MD. The SOC will also be tasked with setting up the community-led Science Survey Group (SSG) that will define the science program and key components of the VLASS.

Self nominations are welcome. The nomination should include name and contact information, including institutional affiliation, and a one paragraph statement giving any relevant interest and experience. Self nominations should also include a brief Curriculum Vitae (CV). Due to the recent shutdown, acceptance of nominations was extended to 5pm ET on Monday 21 October 2013. Updated 21 Oct: Nominations are now closed.

Colleagues who can represent the diverse interests of potential VLASS users, including those from multiple wavelength regimes, or colleagues who have expertise in sky survey planning and oversight, or those with interest in any of the science areas that would benefit from the VLASS, are all good candidates for the SOC. If you find this opportunity to participate in and enable the creation and definition of this next-generation large radio-wavelength survey compelling, or know of someone who would be an excellent candidate, please consider responding to this nomination call.

Regards,

Stefi Baum, Chair, VLASS Science Organizing Committee
Steve Myers, Lead, VLASS Survey Design Group
Claire Chandler, VLASS Project Director

Reminder: Call for White Papers, Deadline Extended to Dec 15

Posted 27 November 2013

A gentle reminder that Individuals or groups interested in attending and speaking at the workshop are strongly encouraged to submit white papers on the VLASS. See the Call for VLASS White Papers link to the left for more details.

We have extended the White Paper submission deadline to 15 December 2013. In order to help us in organizing the AAS Workshop, we also request those who plan to submit White Papers to submit an abstract using the submission link by Dec 2 (or soon thereafter) so we will have an idea of what is being worked on. This is not a requirement for White Paper submission, and submission of an abstract does not bind you to submitting a White Paper with that exact abstract! This is to help us out now that the deadline has pushed into December.

Also, if you are a White Paper author and plan to be at the AAS Workshop, please indicate this in your abstract placeholder (or send us a separate email to vlass@nrao.edu). We would like to get an idea of attendance ahead of time, as there is no registration requirement (and you do not have to register for the AAS meeting to attend our public workshop).

SOC Appointed and at Work

Posted 12 December 2013

The recently appointed Science Organizing Committee for the upcoming Very Large Array Sky Survey Workshop at the AAS meeting is hard at work. The SOC members are:

  • Stefi Baum (RIT, Chair)
  • Shami Chatterjee (Cornell)
  • Tracy Clarke (NRL)
  • Jim Condon (NRAO)
  • Jackie Hodge (NRAO)
  • Karl Menten (MPIfR)
  • Eric Murphy (IPAC)
  • Steven Myers (NRAO, ex-officio)
  • Aneta Siemiginowska (CXC/SAO)
  • Vernesa Smolcic (U. Zagreb)
  • Alicia Soderberg (Harvard)
  • Michael Strauss (Princeton)
  • Rick White (STSCI)

A reminder that the workshop will be held 10:00 AM to 4:00 AM Sunday January 5 2014, as part of the AAS Meeting on the National Harbor in Maryland. No registration
required. All interested community members welcome - come and bring your collaborators, students, and colleagues from across the multi-wavelength spectrum!

Roughly a dozen White Papers and Abstracts have already been received covering diverse topics ranging from transients to lensing to polarization, covering our galaxy to the far
reaches of the universe and everything in between. There are less than 4 days remaining before the white paper submission deadline, so please consider submitting even a brief document with your ideas! And let us know if you plan on attending the workshop.

Initial White Papers Recieved and Posted

Posted 17 December 2013

We have received 18 White Papers and Abstracts in response to the first call for the December 15 deadline. Thanks to all who authored papers! You can find these for download on the VLASS White Paper page.

Note that if you missed the deadline or are inspired by the first round of papers with a new idea, we will be accepting submissions throughout the survey definition process so go ahead and tell us about it!

Update 3 January 2014

We now have received a total of 21 white papers and abstracts and posted online.
