Magnetic-Field Gives Clues Galaxy-Formation
2015/6/18
Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy's main spiral arm. The discovery, they said, helps explain how galacti...

Brief pulse detected by Arecibo telescope appears to come from far beyond our galaxy.The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico...
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
2012/2/22
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
2011/10/13
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...

Discovery Prospects Biogenic Supernova Signature
2010/11/30
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
2010/11/30
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
2010/11/30
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
2010/11/30
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
2010/11/30
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...

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
2010/11/1
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 ...
