A New Census of the 0.2 < z < 3.0 Universe. I. The Stellar Mass Function [PDF]

Astrophysical Journal, 2019
There has been a long-standing factor-of-two tension between the observed star formation rate density and the observed stellar mass buildup after z ∼ 2.

Mass of the dynamically hot inner stellar halo predicts the ancient accreted stellar mass [PDF]

Astronomy & Astrophysics, 2022
Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical structure that we call the “hot inner stellar halo”, defined by stars on dynamically hot orbits with circularity λz < 0.5 at 3.5 kpc < r ≲ 2 Re, is a strong indicator of ...

First results from the IllustrisTNG simulations: the stellar mass content of groups and clusters of galaxies [PDF]

, 2017
The IllustrisTNG project is a new suite of cosmological magneto-hydrodynamical simulations of galaxy formation performed with the Arepo code and updated models for feedback physics.

Stellar-mass microlensing of gravitational waves [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT When gravitational waves (GWs) pass through the nuclear star clusters of galactic lenses, they may be microlensed by the stars. Such microlensing can cause potentially observable beating patterns on the waveform due to waveform superposition and magnify the signal.

No Significant Evolution of Relations between Black Hole Mass and Galaxy Total Stellar Mass Up to z ∼ 2.5 [PDF]

Astrophysical Journal, 2019
We investigate the cosmic evolution of the ratio between black hole (BH) mass (MBH) and host galaxy total stellar mass (Mstellar) out to z ∼ 2.5 for a sample of 100 X-ray-selected moderate-luminosity, broad-line active galactic nuclei (AGNs) in the ...

The Distribution of Stellar Mass in the Pleiades [PDF]

The Astrophysical Journal, 2008
As part of an effort to understand the origin of open clusters, we present a statistical analysis of the currently observed Pleiades. Starting with a photometric catalog of the cluster, we employ a maximum likelihood technique to determine the mass distribution of its members, including single stars and both components of binary systems.

Evolution of the galaxy stellar mass functions and UV luminosity functions at z = 6−9 in the Hubble Frontier Fields [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present new measurements of the evolution of the galaxy stellar mass functions (GSMF) and UV luminosity functions (UV LF) for galaxies from $z=6-9$ within the Frontier Field cluster MACSJ0416.1-2403 and its parallel field.

ON THE ORIGIN OF STELLAR MASSES [PDF]

The Astrophysical Journal, 2011
It has been a longstanding problem to determine, as far as possible, the characteristic masses of stars in terms of fundamental constants; the almost complete invariance of this mass as a function of the star-forming environment suggests that this should be possible. Here I provide such a calculation.

The Stellar Mass Components of Galaxies: Comparing Semi-Analytical Models with Observation [PDF]

, 2010
We compare the stellar masses of central and satellite galaxies predicted by three independent semianalytical models with observational results obtained from a large galaxy group catalogue constructed from the Sloan Digital Sky Survey.
