Science Results

GRAVITY and MIRC-X are delivering breakthrough results in the following areas:

Galactic center black hole Protoplanetary disk imaging Exoplanet characterization Stellar surface imaging

More than 50 papers have been published by GRAVITY and MIRC-X collaborations. See my publications list in the CV. A few highlights below.

GW Ori: Misaligned and warped Protoplanetary Disk around a Triple-Star System (from MIRC-X). Press Release and Science Journal paper (led by S. Kraus).

First Successful Test of Einstein’s General Relativity Near Supermassive Black Hole (from GRAVITY observations). . Press Release and Paper

GRAVITY observations show breaking spectrum of exoplanets using better filter of planet signal from host star using interferometry coherence. Press release and paper.
