Re: Galactic WG Summary so far (comments please!)

Hi Greg et al.-- A few assorted thoughts (1) There has been quite some disagreement on this forum about the spectral index for the "thermal" sources. My big concern is that if one use nu^1, then there appears to be to first order, little difference between an S Band survey at 25 uJy RMS an...

Re: Impact of surveys, impact on peer-reviewed science

Two thoughts, possibly useful or possibly not. First, on using citations to determine impact: If we just care about the time spent on the VLA being 'useful' ( how many people use data taken by the VLA) then the above are good metrics (the maximum number of citations, or a large number of unique user...

Re: Galactic WG Summary so far (comments please!)

To clarify: I mean that I would like to see the parameters (and science case) that would be ideal for a Galactic low-frequency, high-resolution survey. What will the proposed all-sky component of the Extragalactic working group accomplish for Galactic science? Where is it an improvement over what ca...

Re: Galactic WG Summary so far (comments please!)

I can't contribute much because this is not my area of science expertise, and the little I know really just pertains to an interest in star formation, but I will at least try to give a brief defense of the reasons to go to higher frequencies in order to optimize the science done with thermal sources...

Re: Galactic WG Summary so far (comments please!)

From what I understand, Sanjay is no longer strongly pushing for this (but please correct me if I am wrong). The survey proposed in his white paper was low-frequency (S or L), but in C+D+GBT configurations, so as to be optimized for extended emission and ISM tracers. Note that I am similarly making ...

Re: Galactic Survey science case

In regards to studies of compact objects, I have a couple of questions and comments First, there is some talk of a wide or all-sky component of VLASS in the extragalactic group which would potentially be at S-band, A or B configuration, and having an RMS sensitivity of some tens of microJy (35-50, l...

Re: Galactic Survey Design

Ku-band Galactic plane survey (GUTS; Sjouwerman et al. white paper) WHERE will the survey coverage be: -The entire observable northern Galactic plane (l=-20 to +260, b +/-5), matching the area of existing surveys from Spitzer, WISE and Planck, at a comparable 1'' resolution. The continuum sensitivit...

Galactic Survey Design

In an effort to start converging on a survey strategy, I would like to encourage people to put forward survey designs for discussion. To quote Rachel: "The type of survey being envisioned may be a uniform one or tiered, can total to around 10,000 hours, and should be completable in about 5 year...

Re: Galactic Survey science case

my personal vote would be for the doing a smaller area (say centred around l = 30) at around 22 GHz since there are more lines, the thermal emission is stronger and with the increased sensitivity we could get the first unbiased census of hyper-compact HII regions, water masers and a range of other ...

Re: Galactic Survey science case

Also note that there are already plans underway/ observations in progress for a GBT-KFPA survey of ammonia in the Galactic plane: RAMPS, or the Radio Ammonia Mid Plane Survey (PI: James Jackson). If there were interest in a focused/targeted K-band VLA follow-up survey component, the existence of RAM...
