Optical monitoring of massive black holes is able to measure distances within the accretion flows, and to deduce the mass of the black hole. We have recently found that the same technique is viable using narrow Fe K emission lines in X-rays, potentially making it possible to measure black hole masses in many, many galaxies …
Dr. Bailey Tetarenko, the Department of Astronomy McLaughlin Fellow, has arrived from Albert and is getting straight into work with Gemini and Magellan. Dr. Elias Kammoun has arrived from SISSA in Italy, and is jumping on studies of quasars and Seyfert-2 AGN. Dr. Abigail Stevens, an NSF Astronomy & Astrophysics Postdoctoral Fellow, has arrived from …
Recent work by Jon concerning a very rapidly spinning black hole has been featured on AAS/NOVA. The research made use of the new NICER experiment aboard the International Space Station. A Rapidly Spinning Black Hole with a Warped Disk
Undergraduate researcher Anthony Morales, currently working on X-ray and UV light curves of AGN, has been awarded the Bodine Scholarship from the Department of Physics.
Bailey Tetarenko will join the group in Fall 2018, having won the Department’s McLaughlin Fellowship.
NASA has named Jon as one of five US “Participating Scientists” in the XARM mission, a partnership of JAXA, NASA, and ESA that will launch an X-ray calorimeter spectrometer in 2021.
Elias Kammoun, a student at SISSA in Trieste and an expert on AGN and quasars, will join the group as a postdoc in Fall 2018. Welcome, Elias!
Ms. Abigail Stevens (soon, Dr. Stevens), graduate student at the University of Amsterdam, has won an NSF Astronomy & Astrophysics Postdoctoral Fellowship. After graduation, she will join the group in Fall 2018. Congratulations to Abigail, and what good news for us!
Dr. Nathalie Degenaar, former Hubble fellow in the group and now at the University of Amsterdam, has been awarded a Swift Key Program. The two-cycle program will monitor the massive black hole, Sgr A*, as well as many X-ray binaries, over the course of two years. Mark and Jon are Co-Is on this program.
10/4/17 The NuSTAR Obscured Seyferts Survey will complete a volume-limited survey of black holes in heavily obscured environments, wherein black holes may grow especially quickly. This will enable more accurate estimates of obscured accretion power and black hole growth over large cosmological volumes.
