Multiwavelength Observations of Ultraluminous X-Ray Sources
Philip Kaaret
Multiwavelength observations may help us understand the physical nature of the ultraluminous X-ray sources (ULXs) found in external galaxies. Enabled by the arcsecond X-ray source…
The Relativistic Astrophysics Explorer: A New Mission for X-Ray Timing
P. Kaaret, J. Grindlay, F. K. Lamb +3
The great success of the Rossi X-Ray Timing Explorer (RXTE) has given us a new probe to study strong gravitational fields and to measure the physical properties of black holes and…
Pulsar Radiation and Quantum Gravity
Philip Kaaret
Quantum gravity may lead to an energy dependence in the speed of light. The high energy radiation from gamma-ray pulsars can be used to place limits on such effects. We find that e…
The Unidentified Galactic EGRET Sources
Philip Kaaret
The nature of the unidentified gamma-ray point sources in the galactic plane is a long standing puzzle of gamma-ray astronomy. Kaaret and Cottam (1996) showed that 16 of the 25 uni…
