A Statistically Robust Constraint on the Evolution of Field LMXBs We will survey with Chandra and HST 11 nearby elliptical galaxies to make first-ever robust empirical measurements of how field LMXBs evolve as their parent stellar populations age. Our observations will robustly test (to the 96.5-99.4% confidence level) theoretical population synthesis models, which predict a decline in field LMXBs with increasing age. Our survey will also contain detections for ~800 globular cluster (GC) LMXBs, dramatically improving constraints on whether GC LMXBs seed field LMXBs by being kicked out of their host GCs. To perform this experiment, we will leverage >4 Ms of Chandra exposures and >35 HST orbits for 9 galaxies that exist in the archive, and will add 255 ks of new Chandra time and two new HST orbits for two young early-type galaxies. In this set of observations, we will be observing NGC 3585 in two unique observational fields with ACS in two bands: F475W and F850LP. These two observations will supplement existing archival data (in the same ACS bands) that cover the center of the galaxy. Our intention is to combine the two new fields with the existing archival field to create a mosaic of the galaxy. Therefore, our field choices are based on covering to the largest extent possible the entire D25 area of NCGC 3585 when considering the already covered archival area.
