A Strong X-Ray Flux Ratio Anomaly in the Quadruply Lensed Quasar PG 1115+080
David Pooley, Jeffrey A. Blackburne, Saul Rappaport +2
PG 1115+080 is a quadruply lensed quasar at z=1.72 whose image positions are well fit by simple models of the lens galaxy (at z=0.31). At optical wavelengths, the bright close pair…
Discovery of a 3.6-hr Eclipsing Luminous X-Ray Binary in the Galaxy NGC 4214
Kajal K. Ghosh, Saul Rappaport, Allyn F. Tennant +3
We report the discovery of an eclipsing X-ray binary with a 3.62-hr period within 24" of the center of the dwarf starburst galaxy NGC 4214. The orbital period places interesting co…
X-ray and Optical Eclipses in ULXs as Possible Indicators of Black Hole Mass
David Pooley, Saul Rappaport
Ultraluminous X-ray sources (ULXs) with 10^39 < L_x < 10^41 erg/s have been discovered in great numbers in external galaxies with ROSAT, Chandra, and XMM-Newton. The central questi…
X1908+075: A Pulsar Orbiting in the Stellar Wind of a Massive Companion
A. M. Levine, S. Rappaport, R. Remillard +1
We have observed the persistent but optically unidentified X-ray source X1908+075 with the PCA and HEXTE instruments on RXTE. The binary nature of this source was established by We…
Accretion Onto Fast X-Ray Pulsars
S. A. Rappaport, J. M. Fregeau, H. Spruit
The recent emergence of a new class of accretion-powered, transient, millisecond X-ray pulsars presents some difficulties for the conventional picture of accretion onto rapidly rot…
