Stellar-mass microlensing of gravitational waves [PDF]

open access: yesMonthly 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.

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

open access: yesMonthly 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.

A Statistical Relation between Mass, Age, and Velocity Dispersion in the Solar Neighborhood

open access: yesThe Astrophysical Journal, 2023
The stellar kinematics of the Galactic disk are the main factors constraining disk formation and evolution processes in the Milky Way. In this paper, we investigate a statistical relation between stellar mass, age, and velocity dispersion for stars in ...

A detached stellar-mass black hole candidate in the globular cluster NGC 3201 [PDF]

open access: yes, 2018
As part of our massive spectroscopic survey of 25 Galactic globular clusters with MUSE, we performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction. In this cluster, we found one curious star at the main-sequence

Mass–Metallicity Relationship of SDSS Star-forming Galaxies: Population Synthesis Analysis and Effects of Star Burst Length, Extinction Law, Initial Mass Function, and Star Formation Rate

open access: yesThe Astrophysical Journal, 2023
We investigate the mass–metallicity relationship of star-forming galaxies by analyzing the absorption line spectra of ∼200,000 galaxies in the Sloan Digital Sky Survey.

The Distribution of Stellar Mass in the Pleiades [PDF]

open access: yesThe 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.

Relationships between Hi Gas Mass, Stellar Mass, and the Star Formation Rate of HICAT+WISE (H i-WISE) Galaxies [PDF]

open access: yesAstrophysical Journal, 2018
We have measured the relationships between H i mass, stellar mass, and star formation rate using the Hi Parkes All-Sky Survey Catalog (HICAT) and the Wide-field Infrared Survey Explorer (WISE).

The Roles of Morphology and Environment on the Star Formation Rate–Stellar Mass Relation in COSMOS from 0 < z < 3.5

open access: yesThe Astrophysical Journal, 2023
We investigate the relationship between environment, morphology, and the star formation rate (SFR)–stellar mass relation derived from a sample of star-forming (SF) galaxies (commonly referred to as the “star formation main sequence”, SFMS) in the COSMOS ...

ON THE ORIGIN OF STELLAR MASSES [PDF]

open access: yesThe 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.

From Halos to Galaxies. VII. The Connections between Stellar Mass Growth History, Quenching History, and Halo Assembly History for Central Galaxies

open access: yesThe Astrophysical Journal, 2023
The assembly of galaxies over cosmic time is tightly connected to the assembly of their host dark matter halos. We investigate the stellar mass growth history and the chemical enrichment history of central galaxies in the Sloan Digital Sky Survey Mapping
