Tuesday. Cologne yesterday was fun, but didn't get to finish reading astro-ph yesterday.
Wed-Sun, Mon-Sun. Lost the astro-ph write-up during traveling (not that I read that much). Naoko came to visit, and we went to Brussels and Rome.

A Hubble space telescope survey of H2 emission in the circumstellar environments of young stars
France, et al
Look at exoplanetary systems and their molecular disks. H2 emission appears to originate in a rotating disk at r<3AU.

Assembly of the red sequence in infrared-selected galaxies clusters from the IRAC shallow cluster survey
Snyder, ... Stern, ... Dey, Jannuzi, Perlmutter et al
L* red sequence galaxies in 11 IR selected galaxies at in clusters at 1<z<1.5 (present day >1e15 Msun cluster precursors).

Theory of stellar population synthesis with an application to N-body simulations
Pasetto, Chiosi, Kawata
New SPS to predict color magnitude diagrams (CMDs) for many stars, in galaxy N-body sims. Requires information on SF and chemical enrichment histories (age and metallicity of all star particles as a function of time). Star particles approximately have mass of star clusters (a single SP). Each particle a SSP,

Magnitude gap statistics and the conditional luminosity function
More
Hearin+2012: suggest halo mass-richness calibration of galaxy clusters can be improved by using the difference in the magnitude of the brightest and the second brightest galaxy (magnitude gap) as an additional observable; at odds with Paranjape & Sheth 2012 (PS12): magnitude distribution of the brightest galaxies can be explained on order statistics of luminosities randomly sampled from the total galaxy luminosity function. Find: CLF for galaxies which varies with halo mass (consistent with existing observations) naturally leads to a magnitude gap distribution which changes as a function of halo mass at fixed richness. Luminosity distribution
