Perspectives on Gamma-Ray Pulsar Emission
Matthew G. Baring
Pulsars are powerful sources of radiation across the electromagnetic spectrum. This paper highlights some theoretical insights into non-thermal, magnetospheric pulsar gamma-ray rad…
Discovery of a Peculiar Dip from GX 301-2
Ersin Gogus, Ingo Kreykenbohm, Tomaso Belloni
We present temporal and spectral properties of a unique X-ray dip in GX 301-2 as seen with Rossi X-ray Timing Explorer in May 2010. The X-ray pulsation from the source gradually de…
A low-magnetic-field Soft Gamma Repeater
N. Rea, P. Esposito, R. Turolla +8
Soft gamma repeaters and anomalous x-ray pulsars form a rapidly increasing group of x-ray sources exhibiting sporadic emission of short bursts. They are believed to be magnetars, i…
Accretion in the spin-down regime
K. Yavuz Eksi, Erlin Kutlu
Accretion driven millisecond X-ray pulsars can accrete over a wide range of mass flow rates. The pulsations persist even at small accretion rates at which these objects would be ex…
Search for High-Energy Gamma-ray Emission from an Anomalous X-ray Pulsar, 4U 0142+61
Sinem Sasmaz Mus, Ersin Gogus
Until 2004, Anomalous X-ray Pulsars (AXPs) were known as strong emitters of soft X-rays only (< 10 keV). The discovery of hard X-ray component from AXPs provided important insight…
Spatial, Temporal and Spectral Properties of X-ray Emission from the Magnetar SGR~0501+4516
Ersin Gogus, Peter M. Woods, Chryssa Kouveliotou +3
SGR~0501+4516 was discovered with the Swift satellite on 2008 August 22, after it emitted a series of very energetic bursts. Since then, the source was extensively monitored with S…
