A 15.65 solar mass black hole in an eclipsing binary in the nearby spiral galaxy Messier 33
Jerome A. Orosz, Jeffrey E. McClintock, Ramesh Narayan +8
Stellar-mass black holes are discovered in X-ray emitting binary systems, where their mass can be determined from the dynamics of their companion stars. Models of stellar evolution…

The 2003 Outburst of the X-ray Transient H 1743-322: Comparisons with the Black Hole Microquasar XTE J1550-564
Jeffrey E. McClintock, Ronald A. Remillard, Michael P. Rupen +4
The bright X-ray transient H 1743-322 was observed daily by the Rossi X-ray Timing Explorer (RXTE) during most of its 8-month outburst in 2003. We present a detailed spectral analy…
Evaluating Spectral Models and the X-ray States of Neutron-Star X-ray Transients
Dacheng Lin, Ronald A. Remillard, Jeroen Homan
We propose a hybrid model to fit the X-ray spectra of atoll-type X-ray transients in the soft and hard states. This model uniquely produces luminosity tracks that are proportional…

We report on a three year spectroscopic monitoring program of the H-alpha emission in the massive X-ray binary LS I +65 010 = 2S 0114+650, which consists of a B-supergiant and a sl…
X-ray Properties of Black-Hole Binaries
Ronald A. Remillard, Jeffrey E. McClintock
We review the properties and behavior X-ray binaries that contain an accreting black hole. The larger majority of such systems are X-ray transients, and many of them were observed…
The Spin of the Near-Extreme Kerr Black Hole GRS 1915+105
Jeffrey E. McClintock, Rebecca Shafee, Ramesh Narayan +3
Based on a spectral analysis of the X-ray continuum that employs a fully relativistic accretion-disk model, we conclude that the compact primary of the binary X-ray source GRS 1915…

Edward M. Cackett, Rudy Wijnands, Ron Remillard
We report the discovery of an X-ray transient, observed in outburst with XMM-Newton on March 20, 2003, and with position 18h12m27.8s, -18 12 34 (J2000, approximate positional error…
X-ray Spectral States and High-Frequency QPOs in Black Hole Binaries
R. A. Remillard
The high-frequency quasi-periodic oscillations in the X-ray emission of black hole binaries and candidates are briefly examined with respect to the question of X-ray states. We use…
The Rates of type I X-ray Bursts from Transients Observed with RXTE: Evidence for Black Hole Event Horizons
Ronald A. Remillard, Dacheng Lin, Randall L. Cooper +1
We measure the rates of type I X-ray bursts, as a function of the bolometric luminosity, from a likely complete sample of 37 non-pulsing transients (1996-2004). Our goals are to te…
Estimating the Spin of Stellar-Mass Black Holes via Spectral Fitting of the X-ray Continuum
Rebecca Shafee, Jeffrey E. McClintock, Ramesh Narayan +3
We fit X-ray spectral data in the thermal dominant or high soft state of two dynamically confirmed black holes, GRO J1655-40 and 4U 1543-47, and estimate the dimensionless spin par…

The three X-ray states of active accretion in black-hole binaries have been re-defined to focus attention on different physical elements that may contribute radiation: the accretio…
