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...
Discovery of the correspondence between intra-cluster radio emission and a high pressure region detected through the Sunyaev-Zel'dovich effect
galaxies: clusters: individual: RX J1347-1145 – radio continuum: galaxies – X-rays: galaxies: clusters – cosmic back- ground radiation
2011/10/18
We analyzed new 237 MHz and 614 MHz GMRT data of the most X-ray luminous galaxy cluster, RX J1347-1145. Our radio results are compared with the MUSTANG 90 GHz Sunyaev-Zel'dovich effect map and with re...
The discovery of geomagnetically trapped cosmic ray antiprotons

2011/10/19
The existence of a significant flux of antiprotons confined to Earth's magnetosphere has been considered in several theoretical works. These antiparticles are produced in nuclear interactions of energ...
Discovery of a broad O VIII Ly alpha line in the ultra-compact X-ray binary 4U 1543-624
accretion accretion discs binaries-X-rays individual 4U 1543-624
2010/11/15
We report the discovery of a broad emission feature at ∼ 0.7 keV in the spectra of the ultracompact X-ray binary 4U 1543-624, obtained with the high-resolution spectrographs of the
XMM-Newton a...
Discovery of a QPO in the X-ray pulsar 1A 1118-615: correlated spectral and aperiodic variability
X-rays binaries — pulsars individual 1A 1118-615
2010/11/10
Aims. Our goal is to investigate the X-ray timing and spectral variability of the high-mass X-ray binary 1A 1118-615 during a type-II outburst.
A note on the discovery of a 2M_\odot pulsar
dense matter elementary particles pulsars general —stars neutron
2010/11/10
It is conventionally thought that the state equation of dense matter softens and thus cannot result in high maximum mass if pulsars are quark stars, and that a recently discovered 2M⊙ pulsar (PSR J161...

Despite their discovery potential touching a wide range of science, construction of TeV gamma-ray telescopes, Auger, IceCube and a suite of other particle astrophysics experiments has been largely mot...
