The Nature of Nonthermal X-ray Filaments Near the Galactic Center
F. Yusef-Zadeh, M. Wardle, M. Muno +2
Recent Chandra and XMM-{\it Newton} observations reported evidence of two X-ray filaments G359.88-0.08 (SgrA-E) and G359.54+0.18 (the ripple filament) near the Galactic center. The…
GRB 070201: A possible Soft Gamma Ray Repeater in M31
E. O. Ofek, M. Muno, R. Quimby +13
The gamma-ray burst (GRB) 070201 was a bright short-duration hard-spectrum GRB detected by the Inter-Planetary Network (IPN). Its error quadrilateral, which has an area of 0.124 sq…
Results from an extensive simultaneous broadband campaign on the underluminous active nucleus M81*: further evidence for mass-scaling accretion in black holes
S. Markoff, M. Nowak, A. Young +13
We present the results of a broadband simultaneous campaign on the nearby low-luminosity active galactic nucleus M81*. From February through August 2005, we observed M81* five time…
A Hot Helium Plasma in the Galactic Center Region
R. Belmont, M. Tagger, M. Muno +2
Recent X-ray observations by the space mission Chandra confirmed the astonishing evidence for a diffuse, hot, thermal plasma at a temperature of 9. K (8 keV) found by previo…
Faint Infrared Flares from the Microquasar GRS 1915+105
S. Eikenberry, K. Matthews, M. Muno +3
We present simultaneous infrared and X-ray observations of the Galactic microquasar GRS 1915+105 using the Palomar 5-m telescope and Rossi X-ray Timing Explorer on July 10, 1998 UT…
The Origin of Diffuse X-ray and -ray Emission from the Galactic Center Region: Cosmic Ray Particles
F. Yusef-Zadeh, M. Muno, M. Wardle +1
(Abridged) The inner couple hundred pcs of our Galaxy is characterized by significant amount of synchrotron-emitting gas, which appears to co-exist with a large reservoir of molecu…
Modulation of the X-ray Fluxes by the AEI
P. Varnière, M. Muno, M. Tagger +1
The Accretion-Ejection Instability (AEI) has been proposed to explain the low frequency Quasi-Periodic Oscillation (QPO) observed in low-mass X-Ray Binaries. Its frequency, typical…
