W. Thomas Vestrand, Gerald H. Share, J. Murphy, David J. Forrest, Erich Rieger, ...

We present a compilation of data for all 258 gamma-ray Ñares detected above 300 keV by the Gamma Ray Spectrometer (GRS) aboard the Solar Maximum Mission satellite. This gamma-ray Ñare sample was...

Evidence for surface cooling emission in the XMM-Newton spectrum of the X-ray pulsar PSR B2334+61 (2005)

McGowan, Katherine E., Zane, Silvia, Cropper, Mark, Vestrand, W. Thomas, Ho, Cheng

We report on the first XMM-Newton observation of the Vela-like pulsar PSR B2334+61. Spectral analysis reveals soft X-ray emission, with the bulk of the photons emitted at energies below ~1.5 keV. We...

CASTER - a concept for a Black Hole Finder Probe based on the use of new scintillator technologies (2005)

McConnell, Mark L., Bloser, Peter F., Case, Gary, Cherry, Michael, Cravens, James, Guzik, T. Gregory, ...

The primary scientific mission of the Black Hole Finder Probe (BHFP), part of the NASA Beyond Einstein program, is to survey the local Universe for black holes over a wide range of mass and accretion...

XMM-Newton Observations of PSR B1706-44 (2003)

McGowan, Katherine E., Zane, Silvia, Cropper, Mark, Kennea, Jamie A., Cordova, France A., Ho, Cheng, ...

We report on the XMM-Newton observations of the young, 102 ms pulsar PSR B1706-44. We have found that both a blackbody plus power-law and a magnetized atmospheric model plus power-law provide an...

A Cluster of Galaxies hiding behind M31: XMM-Newton observations of RX J0046.4+4204 (2003)

Kotov, Oleg V., Trudolyubov, Sergey, Vestrand, W. Thomas

We report on our serendipitous discovery with the XMM-Newton Observatory of a luminous X-ray emitting cluster of galaxies that is located behind the Andromeda galaxy (M31). X-ray emission from the...

Detection of Pulsed X-ray Emission from XMM-Newton Observations of PSR J0538+2817 (2003)

McGowan, Katherine E., Kennea, Jamie A., Zane, Silvia, Cordova, France A., Cropper, Mark, Ho, Cheng, ...

We report on the XMM-Newton observations of the 143 ms pulsar PSR J0538+2817. We present evidence for the first detections of pulsed X-rays from the source at a frequency which is consistent with the...

Real-Time Detection of Optical Transients with RAPTOR (2002)

Borozdin, Konstantin, Brumby, Steven, Galassi, Mark, McGowan, Katherine, Starr, Dan, Vestrand, W. Thomas, ...

Fast variability of optical objects is an interesting though poorly explored subject in modern astronomy. Real-time data processing and identification of transient celestial events in the images is...
