Dormant Black Hole Eats Star,Becomes X-Ray Beacon
Dormant Black Hole Eats Star X-Ray Beacon
2016/7/4
Roughly 90 percent of the biggest black holes in the known universe are dormant, meaning that they are not actively devouring matter and, consequently, not giving off any light or other radiation. But...
HAWC Gamma-Ray Observatory Reveals New Look at the Very-high-energy Sky
HAWC Gamma-Ray Observatory Very-high-energy Sky
2016/4/25
The United States and Mexico constructed the High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory to observe some of the most energetic phenomena in the known universe—the aftermath wh...
Discovery of the neutron star spin and orbital period from the Be/X-ray binary IGR J05414-6858 in the LMC
Discovery neutron star spin orbital the Be/X-ray binary IGR J05414-6858 the LMC
2012/2/23
The number of known Be/X-ray binaries in the Large Magellanic Cloud is small compared to the observed population of the Galaxy or the Small Magellanic Cloud. The discovery of a system in outburst prov...
The Gamma-Ray Blazar PKS 0208-512, a Multi-Wavelength Investigation
Gamma-Ray Blazar PKS 0208-512 Multi-Wavelength Investigation
2012/2/23
The gamma-ray blazar PKS 0208-512 has shown strong periods of flaring, at all frequencies from radio to gamma-ray. This has led to its inclusion in the TANAMI project, which tracks the jets of souther...
Thermonuclear X-ray bursts from the 401 Hertz accreting pulsar IGR J17498-2921: indication of burning in confined regions
Thermonuclear X-ray bursts pulsar IGR J17498-2921 indication confined regions
2012/2/23
We use the 2011 Rossi X-ray Timing Explorer (RXTE) proportional counter array (PCA) data of the 401 Hz accreting pulsar and burster IGR J17498-2921 to perform timing analysis and time-resolved spectro...
Assessing the Feasibility of Cosmic-Ray Acceleration by Magnetic Turbulence at the Galactic Center
Feasibility Cosmic-Ray Acceleration Magnetic Turbulence the Galactic Center
2012/2/23
The presence of relativistic particles at the center of our galaxy is evidenced by the diffuse TeV emission detected from the inner $\sim$$2^\circ$ of the Galaxy. Although it is not yet entirely clear...
The Search for High-Mass X-ray Binaries in the Phoenix Dwarf Galaxy
High-Mass X-ray Binaries Phoenix Dwarf Galaxy
2012/2/23
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with \emph{XMM-Newton} in July 2009. This local group dwarf galaxy shares similarities with the Small Magellanic Cloud (SMC) incl...
Frame-dragging, disk warping, jet precessing, and dipped X-ray lightcurve of Sw J1644+57
Frame-dragging disk warping jet precessing dipped X-ray lightcurve Sw J1644+57
2012/2/23
The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events, the...
