I am an assistant research scientist at the University of Michigan, Department of Astronomy. I study astrophysical black holes and their relationship with their hosts, be they galaxy nuclei, dark matter halos, stellar clusters, or whatever.

2011 Aug 31 - Gultekin, Richstone, Gebhardt, et al. (2011) "Is there a black hole in NGC 4382?" accepted by ApJ and posted to astro-ph.
2011 Jun 13 - Miller & Gultekin (2011) "X-ray and Radio Constraints on the Mass of the Black Hole in Swift J164449.3+573451" submitted to ApJL and posted to astro-ph. We find that the fundamental-plane based mass of the accreting source is \(\log(M / M_{\scriptscriptstyle \odot}) = 5.9 \pm 1.1 \) . This is an interesting mass range because it rules out masses that are too large to be viable for tidal disruption while still allowing the smaller mass needed for tidal disruption of a white dwarf. UPDATE: accepted by ApJL.
2011 Jun 8 - Miller et al. (2011) "Discovery of a New Supernova Remnant in the Swift Galactic Plane Survey" ATEL circulated. Check out the cool images [PDFs].
