Parametrizing the Stellar Haloes of Galaxies

, 2014
We study the stellar haloes of galaxies out to 70-100 kpc as a function of stellar mass and galaxy type by stacking aligned $r$ and $g$ band images from a sample of 45508 galaxies from SDSS DR9 in the redshift range $0.06\,\le\,z\,\le\,0.1$ and in the ...

Constraints on the relationship between stellar mass and halo mass at low and high redshift

, 2009
We use a statistical approach to determine the relationship between the stellar masses of galaxies and the masses of the dark matter halos in which they reside.

Weighing Betelgeuse: Measuring the mass of alpha Orionis from stellar limb-darkening [PDF]

arXiv, 2011
Stellar limb-darkening is an important tool for constraining the properties of a stellar atmosphere. We present a novel method for relating the fundamental stellar parameters mass and radius to limb-darkening laws using grids of spherical model stellar atmospheres. This method is applied to interferometric observations of the red supergiant Betelgeuse,

Large Dark Matter Content and Steep Metallicity Profile Predicted for Ultradiffuse Galaxies Formed in High-spin Halos

The Astrophysical Journal
We study the stellar properties of a sample of simulated ultradiffuse galaxies (UDGs) with stellar mass M _⋆ = 10 ^7.5 –10 ^9 M _⊙ , selected from the TNG50 simulation, where UDGs form mainly in high-spin dwarf-mass halos.

Physical Correlations of the Scatter between Galaxy Mass, Stellar Content, and Halo Mass

, 2019
We use the UniverseMachine to analyze the source of scatter between the central galaxy mass, the total stellar mass in the halo, and the dark matter halo mass.

Star−Disk Collisions: Implications for Quasi-periodic Eruptions and Other Transients near Supermassive Black Holes

The Astrophysical Journal
We use Athena++ to study the hydrodynamics of repeated star−accretion disk collisions close to supermassive black holes, and we discuss their implications for the origin of quasi-periodic eruptions (QPEs) and other repeating nuclear transients.
