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 Prospects for a Biogenic Supernova Signature
Discovery Prospects Biogenic Supernova Signature
2011/1/10
Within the universe, the astrophysical sites responsible for the production of radioactive 60Fe, of half life 2.62 Myr, are primarily confined to two: Type 1a supernovae and massive stars that end the...
HE 1015-2050: Discovery of a Hydrogen-deficient carbon star at high galactic latitude
HE 1015-2050 Hydrogen-deficient carbon star
2011/1/10
Medium resolution spectral analysis of candidate Faint High Latitude Carbon (FHLC) stars from Hamburg/ESO survey has given us the potential to discover objects of rare types. Two primary spectral char...
Discovery of tidal tails around the distant globular cluster Palomar 14
tidal tails the distant globular cluster Palomar 14
2011/1/13
We report the detection of a pair of degree-long tidal tails associated with the globular cluster Palomar 14, using images obtained at the CFHT. We reveal a power-law departure from a King profile at...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
The XMM-Newton survey of the Small Magellanic Cloud: Discovery of the 11.866 s Be/X-ray binary pulsar XMMUJ004814.0-732204 (SXP11.87)
The XMM-Newton survey the Small Magellanic Cloud
2011/1/11
One of the goals of the XMM-Newton survey of the Small Magellanic Cloud is the study of the Be/X-ray binary population. During one of our first survey observations a bright new transient - XMMUJ004814...
Discovery of the first methanol (CH3OH) maser in the Andromeda galaxy (M31)
the first methanol the Andromeda galaxy
2011/1/10
We present the first detection of a 6.7 GHz Class II methanol (CH3OH) maser in the Andromeda galaxy (M31). The CH3OH maser was found in a Very Large Array (VLA) survey during the fall of 2009. We have...

Dissecting the Moth: Discovery of an off-centered ring in the HD 61005 debris disk with high-resolution imaging
circumstellar matter — planetary systems protoplanetary disks — Techniques
2010/11/15
The debris disk known as “The Moth” is named after its unusually asymmetric surface brightness distribution. It is located around the ∼90Myr old G8V star HD 61005 at 34.5 pc and has previously b...
During their infancy, stars are well known to expel matter violently in the form of well-defined,collimated outflows. A fairly unique exception is found in the Orion BN/KL star-forming region where a ...
Discovery of a QPO in the X-ray pulsar 1A 1118-615: correlated spectral and aperiodic variability

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...
