The Growth of Galaxy Stellar Mass Within Dark Matter Halos [PDF]
The Astrophysical Journal, 2011 We study the evolution of stellar mass in galaxies as a function of host halo mass, using the "MPA" and "Durham" semi-analytic models, implemented on the Millennium Run simulation. The results from both models are similar.

The stellar halo metallicity—luminosity relationship for spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2005 The stellar halos of spiral galaxies bear important chemo-dynamical signatures of galaxy formation. We present here the analysis of 89 semi-cosmological spiral galaxy simulations, spanning ~ 4 magnitudes in total galactic luminosity.

The 6dF Galaxy Survey: Dependence of halo occupation on stellar mass [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 In this paper we study the stellar-mass dependence of galaxy clustering in the 6dF Galaxy Survey. The near-infrared selection of 6dFGS allows more reliable stellar mass estimates compared to optical bands used in other galaxy surveys.

Ghostly Galaxies: Accretion-dominated Stellar Systems in Low-mass Dark Matter Halos [PDF]
The Astrophysical Journal, 2023 Wide-area deep imaging surveys have discovered large numbers of extremely low surface brightness (LSB) dwarf galaxies, which challenge galaxy formation theory and, potentially, offer new constraints on the nature of dark matter.

The “Building Blocks” of Stellar Halos [PDF]
Galaxies, 2017 The stellar halos of galaxies encode their accretion histories. In particular, the median metallicity of a halo is determined primarily by the mass of the most massive accreted object.

Shapes of Stellar Systems and Dark Halos from Simulations of Galaxy Major Mergers [PDF]
, 2006 Using a sample of 89 snapshots from 58 hydrodynamic binary galaxy major merger simulations, we find that stellar remnants are mostly oblate while dark matter halos are mostly prolate or triaxial.

The Baryonic Halos of Isolated Elliptical Galaxies
Galaxies, 2017 Without the interference of a number of events, galaxies may suffer in crowded environments (e.g., stripping, harassment, strangulation); isolated elliptical galaxies provide a control sample for the study of galaxy formation.

SDSS-IV MaNGA: The Effect of Stellar Mass and Halo Mass on the Assembly Histories of Satellite Galaxies [PDF]
The Astrophysical Journal, 2023 We combine an unprecedented MaNGA sample of over 3000 passive galaxies in the stellar mass range 10 ^9 –10 ^12 M _⊙ with the Sloan Digital Sky Survey group catalog by Tinker to quantify how central and satellite formation, quantified by radial profiles ...

The Stellar Content of Galaxy Halos: A Comparison between ΛCDM Models and Observations of M31 [PDF]
, 2008 Recent observations have revealed that high surface brightness, metal-rich debris is present over large regions of the Andromeda (M31) stellar halo. We use a set of numerical models to determine whether extended metal-rich debris is expected to exist in ...

Testing Galaxy Formation Models with the Stellar Mass–Halo Mass Relations for Star-forming and Quiescent Galaxies [PDF]
The Astrophysical JournalThe tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critical constraint for galaxy formation models.
