A Kinematic Study of Wolf-Rayet Stars at the Galactic Center I: Binary Candidates and Constraints on the Binary Fraction
Rory O. Bentley, Tuan Do, Andrea Ghez +13
We report the binary fraction of Wolf-Rayet (WR) stars within 0.5~pc of the Galactic center obtained through the longest time-baseline (1994-2024) kinematic study of this populatio…
Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment
Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23
We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…
Evidence of a Decreased Binary Fraction for Massive Stars Within 20 Milliparsecs of the Supermassive Black Hole at the Galactic Center
Devin S. Chu, Tuan Do, Andrea Ghez +12
We present the results of the first systematic search for spectroscopic binaries within the central 2 x 3 arcsec around the supermassive black hole at the center of the Milky W…
Stellar Populations in the Central 0.5 pc of Our Galaxy III: The Dynamical Sub-structures
Siyao Jia, Ningyuan Xu, Jessica R. Lu +12
We measure the 3D kinematic structures of the young stars within the central 0.5 parsec of our Galactic Center using the 10 m telescopes of the W.~M.~Keck Observatory over a time s…
The Swansong of the Galactic Center Source X7: An Extreme Example of Tidal Evolution near the Supermassive Black Hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +14
We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, pre…
The Star Formation History of the Milky Way's Nuclear Star Cluster
Zhuo Chen, Tuan Do, Andrea M. Ghez +6
We report the first star formation history study of the Milky Way's nuclear star cluster (NSC) that includes observational constraints from a large sample of stellar metallicity me…
Measuring the alpha-abundance of subsolar-metallicity stars in the Milky Way's central half-parsec: testing globular cluster and dwarf galaxy infall scenarios
Rory O. Bentley, Tuan Do, Wolfgang Kerzendorf +4
While the Milky Way Nuclear star cluster has been studied extensively, how it formed is uncertain. Studies have shown it contains a solar and supersolar metallicity population that…
Dense Molecular Clouds in the Crab Supernova Remnant
Alwyn Wootten, Rory O. Bentley, J. Baldwin +7
Molecular emission was imaged with ALMA from numerous components near and within bright H2-emitting knots and absorbing dust globules in the Crab Nebula. These observations provide…
Search for a Variation of the Fine Structure around the Supermassive Black Hole in Our Galactic Center
A. Hees, T. Do, B. M. Roberts +11
Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond General Relativity and the standard model motivated by unificatio…
Envisioning the next decade of Galactic Center science: a laboratory for the study of the physics and astrophysics of supermassive black holes
Tuan Do, Andrea Ghez, Jessica R. Lu +38
As the closest example of a galactic nucleus, the Galactic center (GC) presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environment. We…
The KIC 8462852 Light Curve From 2015.75 to 2018.18 Shows a Variable Secular Decline
Bradley E. Schaefer, Rory O. Bentley, Tabetha S. Boyajian +19
The star KIC 8462852 (Boyajian's Star) displays both fast dips of up to 20% on time scales of days, plus long-term secular fading by up to 19% on time scales from a year to a centu…
