rhapsody-g simulations - I. The cool cores, hot gas and stellar content of massive galaxy clusters [PDF]
, 2015 We present the RHAPSODY-G suite of cosmological hydrodynamic zoom simulations of 10 massive galaxy clusters at the M_(vir) ∼ 10^(15) M⊙ scale. These simulations include cooling and subresolution models for star formation and stellar and supermassive ...

The star formation rate and stellar content contributions of morphological components in the EAGLE simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Hubble sequence provides a useful classification of galaxy morphology at low redshift. However, morphologies are not static, but rather evolve as the growth of structure proceeds through mergers, accretion and secular processes.

A stochastically sampled IMF alters the stellar content of simulated dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Cosmological simulations are reaching the resolution necessary to study ultra-faint dwarf galaxies. Observations indicate that in small populations, the stellar initial mass function (IMF) is not fully populated; rather, stars are sampled in a way that

Virgo Redux: The Masses and Stellar Content of Nuclei in Early-type Galaxies from Multiband Photometry and Spectroscopy [PDF]
, 2017 We present an analysis of 39 nuclei and their early-type hosts in the Virgo Cluster using 10 broadband filters: F300W, F475W, F850LP, F160W, u * griz , and Ks.

ON THE STELLAR CONTENT OF THE STARBURST GALAXY IC10 [PDF]
, 2009 We investigate the stellar content of the starburst dwarf galaxy IC10 using accurate and deep optical data collected with the Advanced Camera for Surveys and with the Wide Field Planetary Camera 2 onboard the Hubble Space Telescope.

THE STELLAR CONTENT OF THE POST-STARBURST S0 GALAXY NGC 5102 [PDF]
, 2008 The stellar content of the S0 galaxy NGC 5102 is investigated using deep r′ and i′ images obtained with GMOS-S. A modest population of bright main-sequence stars and red supergiants is detected throughout the western portion of the disk.

Extremely Low Molecular Gas Content in a Compact, Quiescent Galaxy at z = 1.522 [PDF]
Astrophysical Journal, 2019 One of the greatest challenges to theoretical models of massive galaxy formation is the regulation of star formation at early times. The relative roles of molecular gas expulsion, depletion, and stabilization are uncertain as direct observational ...

The Stellar Content and the Star Formation History of the Local Group Dwarf Galaxy LGS 3 [PDF]
, 1997 The star formation history (SFH) and the properties of the dwarf galaxy LGS3 are analyzed using color-magnitude (CM) diagrams plotted from VRI photometry of 736 stars.
