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…

Ranging Sensor Fusion in LISA Data Processing: Treatment of Ambiguities, Noise, and On-Board Delays in LISA Ranging Observables

Jan Niklas Reinhardt, Martin Staab, Kohei Yamamoto +6

Interspacecraft ranging is crucial for the suppression of laser frequency noise via time-delay interferometry (TDI). So far, the effects of on-board delays and ambiguities on the L…

End-to-end simulation and analysis pipeline for LISA

Jean-Baptiste Bayle, Olaf Hartwig, Marc Lilley +4

The data produced by the future space-based millihertz gravitational-wave detector LISA will require nontrivial pre-processing, which might affect the science results. It is crucia…

Search for vector dark matter in microwave cavities with Rydberg atoms

Jordan Gué, Aurélien Hees, Jérôme Lodewyck +2

We propose a novel experiment to search for dark matter, based on the application of an electric field inside a microwave cavity and electrometry using Rydberg atoms. We show that…

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…
