Astrophysics Research

jay I am an assistant professor in the Department of Physics and Astronomy at Michigan State. I welcome questions from current or prospective students about possible research projects; send me an email at the address listed below.

From 2007-2012 I was a Hubble Fellow and Menzel Fellow at the Harvard-Smithsonian Center for Astrophysics. I got my PhD in astronomy at UC-Santa Cruz/Lick Observatory. Recently my work has focused on studying compact objects, especially on searches for black holes in globular clusters. I am also a proud member of the SAGES group, which studies extragalactic globular cluster systems as a means to understand galaxy formation. Our current focus is the SLUGGS survey. I have broad interests in old stellar populations, including star clusters in the local universe, dwarf galaxies, and mass loss in red giants.

I'm a member of Stars, Milky Way, and Local Volume science collaboration for LSST. Kevin Covey and I chair the sub-group on Star Clusters. I also contributed to the LSST science book, which is here.

My research group at MSU includes postdocs Ricardo Salinas and Mark Peacock, graduate students Tom Hettinger and Laura Shishkovsky, and several undergraduates. Some students are co-advised with Laura Chomiuk.

Do an astro-ph or ADS search on me.

I have two goats, one of whom (Magellan) is pictured to the right.

New: We found a new likely gamma-ray pulsar binary through SOAR followup of an unidentified Fermi-LAT source.
We found the first "hypervelocity" globular cluster around M87. slashdot noticed.
Check out our discovery of black holes in the Milky Way globular cluster M22 (Nature; arXiv; Nature News & Views). Selected media coverage: Science,, Science News, and Scientific American. And now a candidate in M62!

You can find the catalog of M31 globular cluster velocity dispersions, masses, mass-to-light ratios, and radii here. See Strader et al. (2011, AJ, 142, 8) or send me an email for more details.
