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…

Characterizing and Improving the Data Reduction Pipeline for the Keck OSIRIS Integral Field Spectrograph

Kelly E. Lockhart, Tuan Do, James E. Larkin +15

OSIRIS is a near-infrared (1.0--2.4 m) integral field spectrograph operating behind the adaptive optics system at Keck Observatory, and is one of the first lenslet-based integra…

Investigating the Binarity of S0-2: Implications for its Origins and Robustness as a Probe of the Laws of Gravity around a Supermassive Black Hole

Devin S. Chu, Tuan Do, Aurelien Hees +8

The star S0-2, which orbits the supermassive black hole (SMBH) in our Galaxy with a period of 16 years, provides the strongest constraint on both the mass of the SMBH and the dista…

The Post-Periapse Evolution of Galactic Center Source G1: The second case of a resolved tidal interaction with a supermassive black hole

Gunther Witzel, Breann. N. Sitarski, Andrea M. Ghez +13

We present new Adaptive Optics (AO) imaging and spectroscopic measurements of Galactic Center source G1 from W. M. Keck Observatory. Our goal is to understand its nature and relati…

Testing the gravitational theory with short-period stars around our Galactic Center

A. Hees, A. M. Ghez, T. Do +19

Motion of short-period stars orbiting the supermassive black hole in our Galactic Center has been monitored for more than 20 years. These observations are currently offering a new…

Testing General Relativity with stellar orbits around the supermassive black hole in our Galactic center

A. Hees, T. Do, A. M. Ghez +14

In this Letter, we demonstrate that short-period stars orbiting around the supermassive black hole in our Galactic Center can successfully be used to probe the gravitational theory…
