Constraining a companion of the galactic center black hole, Sgr A*
Clifford M. Will, Smadar Naoz, Aurélien Hees +4
We use 23 years of astrometric and radial velocity data on the orbit of the star S0-2 to constrain a hypothetical intermediate-mass black hole orbiting the massive black hole Sgr A…
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…
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…
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…
A population of dust-enshrouded objects orbiting the Galactic black hole
Anna Ciurlo, Randall D. Campbell, Mark R. Morris +9
The central 0.1 parsecs of the Milky Way host a supermassive black hole identified with the position of the radio and infrared source Sagittarius A*, a cluster of young, massive st…
Relativistic redshift of the star S0-2 orbiting the Galactic center supermassive black hole
Tuan Do, Aurelien Hees, Andrea Ghez +26
General Relativity predicts that a star passing close to a supermassive black hole should exhibit a relativistic redshift. We test this using observations of the Galactic center st…
