The high mass end of the stellar mass function: dependence on stellar population models and agreement between fits to the light profile [PDF]
, 2016 We quantify the systematic effects on the stellar mass function that arise from assumptions about the stellar population, as well as how one fits the light profiles of the most luminous galaxies at z∼0.1.

Challenges in Stellar Population Studies [PDF]
, 2009 The stellar populations of galaxies contain a wealth of detailed information. From the youngest, most massive stars, to almost invisible remnants, the history of star formation is encoded in the stars that make up a galaxy.

THE MASSIVE SURVEY. II. STELLAR POPULATION TRENDS OUT TO LARGE RADIUS IN MASSIVE EARLY-TYPE GALAXIES [PDF]
, 2015 We examine stellar population gradients in ∼100 massive early-type galaxies spanning 180 < &sgr; * < 370 ?> km s−1 and MK of −22.5 to −26.5 mag, observed as part of the MASSIVE survey.

BEING WISE. I. VALIDATING STELLAR POPULATION MODELS AND M⋆/L RATIOS AT 3.4 and 4.6 μm [PDF]
, 2014 Using data from the Wide-field Infrared Survey Explorer mission, we have measured near infra-red (NIR) photometry of a diverse sample of dust-free stellar systems (globular clusters, dwarf and giant early-type galaxies) which have metallicities that span

BREATHING FIRE: HOW STELLAR FEEDBACK DRIVES RADIAL MIGRATION, RAPID SIZE FLUCTUATIONS, AND POPULATION GRADIENTS IN LOW-MASS GALAXIES [PDF]
, 2015 We examine the effects of stellar feedback and bursty star formation on low-mass galaxies (Mstar = 2 × 106 − 5 × 1010 M⊙) using the Feedback in Realistic Environments (FIRE) simulations.

Short GRB Host Galaxies. II. A Legacy Sample of Redshifts, Stellar Population Properties, and Implications for Their Neutron Star Merger Origins [PDF]
Astrophysical Journal, 2022 We present the stellar population properties of 69 short gamma-ray burst (GRB) host galaxies, representing the largest uniformly modeled sample to date. Using the Prospector stellar population inference code, we jointly fit photometry and/or spectroscopy
