post Calistoga

Project ideas not to drop:

-- high spatial resolution Y-band spectra of luminous ellipticals (Conroy)

-- binary population with Nidever;
   work out giant ages from giant masses in binaries (Gaia & APOGEE)

-- testing PS1 RR Lyrae in dSph in the MW

-- clarify wide-field spectroscopy telescope (Bernstein)

Notes on the "shallow" JWST NIRSPEC survey of 9000 galaxies

Goal: mini-SDSS at z~2-4
Science case: Arjen's ESO large proposal, but now at z~2-4

2 settings R~1000 & R~1000
S/N goal per resolution element 20

Basic targeting m_AB(integrated, @H or IRAC3.6)<24.5; z>2
[and add the ones that are IRAC-only detections…]

according to Tracy Beck: we get ~150 galaxies per MSA setting [CHECK using APT]

thought: 1x 1000 sec @ 1MSA (or 2x500 sec dithered with 2 slits; is that needed)

thought 36 pointings   --> 36x150 galaxies --> 5500 galaxies

Field:  from CANDELS with ALMA access; 2 different fields;
   within a field, contiguous.

  what are the overhead advantages and cosmic variance drawbacks of different
   MSA settings at identical pointing

To be done: what is the S/N distribution, given actual CANDELS size/slitloss parameters.
 any orient constraints: major axis.

Draft needs to be done by May 9

After the Oxberg meeting April 1-2

Two immediate homework's have arisen:

1) Hogg & Price-Wheelan will work through the known streams, and see what
feasable observational data are most potential-constraining; then the plan could be that
Brani organizes a coherent follow-up effort.

2) Discussion between Schönrich, Martig, Binney have arisen that it would be good
to have action-space diffusion coefficients from numerical/cosmological simulations.
Bovy and Roskar have a machinery that takes N-body simulations to an analytic potential
machinery, which then allows the Stäckel fudge, and ultimately to calculate
the actions for a particle with (x,v) in an N-body simulation.
At a practical level, it needs to be cleared-up what these diffusion coefficients
depend on t,R,sigma?

The claim is that with p(J,age,[X/H] | t_now) one can get the diffusion history,
under the assumption of p(J,age,[X/H]) was very narrow at birth.


3) Needs to define paper scope with Nina
4) Need to define paper scope with Marie
