Re: Galactic counter proposal

I'm willing to write up something about quiescent black hole X-ray binaries. I'll see if Tom Macarrone is willing to help. Section: Galactic Science Enabled by the VLASS The Galactic component would consist of H hours focused on the area ... in the A configuration to obtain approximately 1" res...

Re: Galactic counter proposal

Hi Everyone, Thanks for putting your thoughts down again. I wanted to update you on the track the discussion has headed lately. This coming Monday, we are expected to come together on a consensus and start doling out writing assignments. The plan now is for a pure S-band survey (in something close ...

Re: Galactic counter proposal

I think I speak for many of the Galactic community when I suggest to completely forget about a Galactic contribution and save significant hours that otherwise will waste everybodys (observing) time. There are many good PI programs that could use this LST range for much more interesting science than...

Re: Galactic counter proposal

Hi All, After the telecon, it became clear the simplicity in message was going to win out. So I think there are only two possibilities we could push for; higher resolution and higher sensitivity. 1) If resolution is the truly unique thing the VLASS will add, then why are we not pushing to A configur...

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

And yet both FIRST and NVSS have thrived, and both have had a demonstrably large impact on radio and multi-wavelength science. How can that be? The answer is that the higher resolution of FIRST (with a beam 8 times smaller than NVSS) is essential in doing cross-matches to SDSS and other deep imagin...

Re: VLASS Calculator

I think that just using the upper frequency to set your time on source is overly pessimistic. We really should fold the different expected spectrum throughout the entire band for calculating sensitivities. On the other hand, if we're talking about the mosaic pattern, than I full agree that should pr...

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

Looks like the post I thought I submitted I did not. So here's try two. I'm about to step on a plane, but I guess the point I want to make here is that is why we ask for Ku band. That is, because you don't know what the spectral index is, you want to observe there and deduce it from the measurements...

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

And now for the first two of Elisabeth's points. I'm getting a little tired and want to look at the Meerkat surveys tomorrow in (clearer) detail. For thermal sources it is not just the sensitivity to nu^2 sources, but also sensitivity to recombination lines which should drive the choice of frequency...

Re: Welcome to the VLASS CEO Working Group Sub-Forum

- What steps should we take to involve the broadest community base from the beginning? Perhaps we should actually advertise this a little more broadly. For example, many of us are on the Astronomers Facebook page (plus we could make our own just for VLASS). Also, we could use society e-mail exploder...
