The Large Scale Cosmic-Ray Anisotropy as Observed with Milagro
A. A. Abdo, B. T. Allen, T. Aune +30
Results are presented of a harmonic analysis of the large scale cosmic-ray anisotropy as observed by the Milagro observatory. We show a two-dimensional display of the sidereal anis…
Chandra Observations of the Anomalous X-ray Pulsar 4U 0142+61
Sandeep K. Patel, Chryssa Kouveliotou, Peter M. Woods +7
We present X-ray imaging, timing, and phase resolved spectroscopy of the anomalous X-ray pulsar 4U 0142+61 using the Chandra X-ray Observatory. The spectrum is well described by a…
Light Element Evolution and Cosmic Ray Energetics
R. Ramaty, S. T. Scully, R. E. Lingenfelter +1
Using cosmic-ray energetics as a discriminator, we investigate evolutionary models of LiBeB. We employ a Monte Carlo code which incorporates the delayed mixing into the ISM both of…
Gamma-ray limits on Galactic 60Fe nucleosynthesis and implications on the Origin of the 26Al emission
J. E. Naya, S. D. Barthelmy, L. M. Bartlett +5
The Gamma Ray Imaging Spectrometer (GRIS) recently observed the gamma-ray emission from the Galactic center region. We have detected the 1809 keV Galactic 26Al emission at a signif…
Pulsar X-Ray and Gamma-Ray Pulse Profiles: Constraint on Obliquity and Observer Angles
Alice K. Harding, Alexander G. Muslimov
We model the thermal X-ray profiles of Geminga, Vela and PSR 0656+14, which have also been detected as gamma-ray pulsars, to constrain the phase space of obliquity and observer ang…
Evidence for Absorption due to Highly-Ionized Gas in the Radio-quiet Quasar PG 1114+445
I. M. George, K. Nandra, A. Laor +4
We present results on the X-ray spectrum of the quasar PG 1114+445 from an ASCA observation performed in 1996 June, and a ROSAT observation performed 3 years earlier. We show good…
