Gamma-ray Activity in the Crab Nebula: The Exceptional Flare of April 2011
R. Buehler, J. D. Scargle, R. D. Blandford +18
The Large Area Telescope on board the Fermi satellite observed a gamma-ray flare in the Crab nebula lasting for approximately nine days in April of 2011. The source, which at optic…
Unraveling the Geometry of the Crab Nebula's "Inner Ring"
Martin C. Weisskopf, Ronald F. Elsner, Jeffery J. Kolodziejczak +2
Chandra images of the Crab Nebula resolve the detailed structure of its "inner ring", possibly a termination shock where pulsar-accelerated relativistic particles begin to emit X r…
The Identification of the X-ray Counterpart to PSR J2021+4026
Martin C. Weisskopf, Roger W. Romani, Massimiliano Razzano +16
We report the probable identification of the X-ray counterpart to the gamma-ray pulsar PSR J2021+4026 using imaging with the Chandra X-ray Observatory ACIS and timing analysis with…
A Complete Sample of ULX Host Galaxies
Douglas A. Swartz, Roberto Soria, Allyn F. Tennant +1
One hundred seven ultraluminous X-ray (ULX) sources with 0.3-10.0 keV luminosities in excess of 1e39 erg/s are identified in a complete sample of 127 nearby galaxies. The sample in…
Chandra Phase-Resolved X-ray Spectroscopy of the Crab Pulsar II
Martin C. Weisskopf, Allyn F. Tennant, Dmitry G. Yakovlev +5
We present a new study of the X-ray spectral properties of the Crab Pulsar. The superb angular resolution of the Chandra X-ray Observatory enables distinguishing the pulsar from th…
The Crab Nebula super-flare in April 2011: extremely fast particle acceleration and gamma-ray emission
E. Striani, M. Tavani, G. Piano +47
We report on the extremely intense and fast gamma-ray are above 100 MeV detected by AGILE from the Crab Nebula in mid-April 2011. This event is the fourth of a sequence of reported…
