Tod Strohmayer is presently the Project Scientist for NASA's Rossi X-ray Timing Explorer (RXTE). RXTE conducts a wide-ranging science program that includes observations of accreting compact objects such as black holes and neutron stars. Strohmayer uses RXTE observations as well as other X-ray facilities (such as XMM-Newton and Chandra) to carry out a diverse research program on the physics of compact stellar remnants, including fast X-ray timing measurements of accreting neutron stars and black holes.
X-ray timing studies of ultraluminous X-ray sources in nearby galaxies to explore the question of whether some of these objects are intermediate mass black holes
Fast X-ray timing studies of accreting neutron stars, accreting millisecond pulsars, and X-ray bursting neutron stars
