Hello all,<br />
<br />
I wanted to summarize the response I have received to my call for<br />
ideas for ancillary targetting to the core AS2 science programs. Most<br />
of these ideas would be auxiliary targets to the BOSS program, and<br />
there may be fibers for up to 30 targets per square degree. The<br />
detailed program will be decided by the AS2 management committee. For<br />
them to make their decision, we need documents describing the<br />
following for each category of auxiliary target: <br />
<br />
-A detailed scientific case: why this project is scientifically<br />
compelling. One to two pages would be appropriate here. <br />
<br />
-Target selection details. How are the targets selected? Can<br />
the targets be selected right now, using existing data? <br />
<br />
-The density of targets on the sky. Can the sample be<br />
sparse-sampled? <br />
<br />
-Sky coverage of targets. Is it important that the selection be<br />
uniform over the whole survey footprint? Does it need to be<br />
tiled? Are there specific regions of the sky in which one needs<br />
to target? <br />
<br />
We need these quite soon: as was discussed at the SDSS collaboration<br />
meeting last week, we need to finalize a number of aspects of the AS2<br />
survey, including the targetting of ancillary targets, in the next<br />
month. So we would like the documents (posted to<br />
as2-general@astro.princeton.edu) by two weeks from today, i.e., <br />
April 16. One restriction to keep in mind is that we need to minimize<br />
the effect of cross-talk on the faint (g=22) targets in BOSS; in<br />
practice, this suggests that we can't target objects with fiber<br />
magnitude brighter than r~17. <br />
<br />
Here are the ideas I have heard thus far for ancillary programs:<br />
<br />
-Guinevere Kauffmann and Tim Heckman are interested in targetting<br />
luminous blue galaxies at all redshifts, to understand the<br />
evolution of luminous galaxies from z=0.7 to today. <br />
<br />
-Paco Prada is interested in targetting bright galaxies, especially<br />
those not properly targetted as part of the main SDSS sample due to<br />
problems with the photometric pipeline. (This program may be<br />
affected by the bright limit on targets). <br />
<br />
-There is interest in various SEGUE-related programs, such as<br />
spectroscopically targetting some of the high-density lumps in the<br />
Milky Way, or targetting a sparse sample of BHB stars uniformly<br />
across the survey area. The SEGUE team, and David Hogg, are<br />
interested in pursuing this. <br />
<br />
-Bob Nichol, Daniel Thomas and Claudia Maraston are interested in<br />
high S/N spectroscopy of nearby ellipticals for detailed star<br />
formation history/metallicity studies. <br />
<br />
-Xiaohui Fan is interested in various high-redshift quasar studies,<br />
including: <br />
-A complete i-band dropout survey<br />
-Going fainter in z>4 quasars than the main SDSS survey<br />
-Targetting quasar candidates that were missed due to fiber<br />
collisions, to study the small-scale clustering of quasars<br />
<br />
-Changbom Park is interested in targetting satellite companions of<br />
low-redshift galaxies to study halo dynamics and the properties of<br />
low-luminosity galaxies. <br />
<br />
It is not too late to add to this list!<br />
