Portrait of Jack Steiner

Hi there, and welcome! I’m an astrophysicist with the Chandra X-ray Center working at the Center for Astrophysics | Harvard & Smithsonian. My research is focused on X-ray binary systems, particularly “stellar-mass” black holes.

My colleagues and I are working to measure the spins of these black hole systems, and to study their accretion properties as well.

Word cloud of research topics: black-hole spin, accretion disks, X-ray binaries, continuum fitting
