Assisted inspirals of stellar mass black holes embedded in AGN discs: solving the ‘final au problem’ [PDF]
, 2016 We explore the evolution of stellar mass black hole binaries (BHBs) which are formed in the self-gravitating disks of active galactic nuclei (AGN). Hardening due to three-body scattering and gaseous drag are effective mechanisms that reduce the semi ...

Effect of Mass Gain on Stellar Evolution [PDF]
International Astronomical Union Colloquium, 1981 AbstractIn this paper we present a fully hydrodynamical treatment of the stationary isothermal accretion problem onto a moving gravitating point mass. The derivation is purely analytical. We find that the accretion rate is more than a factor of 50 higher than the accretion rate derived from the partially non-hydrodynamical treatment by Hoyle and ...

GAMA/G10-COSMOS/3D-HST: the 0 < z < 5 cosmic star formation history, stellar-mass, and dust-mass densities [PDF]
, 2017 We use the energy-balance code MAGPHYS to determine stellar and dust masses, and dust corrected star-formation rates for over 200,000 GAMA galaxies, 170,000 G10-COSMOS galaxies and 200,000 3D-HST galaxies.

Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes
, 2019 The merger rate of stellar-mass black hole binaries (sBHBs) inferred by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) suggests the need for an efficient source of sBHB formation.

Stellar Masses and Radii as Constraints on Stellar Models [PDF]
International Astronomical Union Colloquium, 1993 AbstractThe current status of empirical data on stellar masses and radii of sufficient accuracy to give constraints on stellar models is reviewed. Results from the best-studied eclipsing binaries can already trace the main-sequence evolution of 1-10 M⊙ stars in considerable detail and will be even more useful when supplemented by chemical abundance ...

The Incomplete Conditional Stellar Mass Function: Unveiling the Stellar Mass Functions of Galaxies at 0.1 < Z < 0.8 from BOSS Observations [PDF]
, 2018 We propose a novel method to constrain the missing fraction of galaxies using galaxy clustering measurements in the galaxy conditional stellar mass function (CSMF) framework, which is applicable to surveys that suffer significantly from sample selection ...

Radio observations of stellar mass loss [PDF]
Symposium - International Astronomical Union, 1979 A program to search for steady-state thermal emissions from stars has been in progress for several years in Canada (Purton 1976). In this program we have specifically excluded flaring objects (such as β Lyr or HR1099) where non-thermal emission is probably responsible.

The stellar mass-halo mass relation of isolated field dwarfs : a critical test of ΛCDM at the edge of galaxy formation [PDF]
, 2016 We fit the rotation curves of isolated dwarf galaxies to directly measure the stellar mass-halo mass relation (M*-M200) over the mass range 5 × 105 ≲ M*/M⊙ ≲ 108.

Dynamics of Dwarf Galaxies Disfavor Stellar-Mass Black Holes as Dark Matter. [PDF]
Physical Review Letters, 2017 We study the effects of black hole dark matter on the dynamical evolution of stars in dwarf galaxies. We find that mass segregation leads to a depletion of stars in the center of dwarf galaxies and the appearance of a ring in the projected stellar ...

The Impact of Environment on the Stellar Mass–Halo Mass Relation [PDF]
The Astrophysical Journal, 2018 Abstract A large variance exists in the amplitude of the stellar mass–halo mass (SMHM) relation for group- and cluster-size halos. Using a sample of 254 clusters, we show that the magnitude gap between the brightest central galaxy (BCG) and its second or fourth brightest neighbor accounts for a significant portion of this variance.
