Magnetic-Field Gives Clues Galaxy-Formation
2015/7/13
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...
Astronomers join forces to speed discovery of habitable worlds
Astronomers speed discovery habitable worlds
2015/4/30
UC Berkeley astronomers will lead one of 16 new projects funded by NASA to coordinate different exoplanet searches to more efficiently find habitable planets around other stars, and perhaps extraterre...
Discovery of a 136 Millisecond Radio and X-Ray Pulsar in Supernova Remnant G54.1+0.3
G54.1+0.3 PSR J1930+1852
2014/12/26
We report the discovery of a pulsar with period P = 136 ms and dispersion measure 308 cm-3 pc in a deep observation of the supernova remnant (SNR) G54.1+0.3 with the Arecibo radio telescope. Timing me...
Discovery of a Molecular Outflow in the Haro 6-10 Star-forming Region

2014/12/23
We present high sensitivity 12CO and 13CO J=1!0 molecular line maps covering the full extent of the parsec scale Haro 6-10 Herbig-Haro (HH) flow. We report the discovery of a molecular CO outflow alon...
DISCOVERY OF A LUMINOUS BLUE VARIABLE WITH AN EJECTION NEBULA NEAR THE QUINTUPLET CLUSTER
variable star Pistol Star
2014/12/22
We report on the discovery of a luminous blue variable (LBV) lying 7 pc in projection from the Quintuplet cluster. This source, which we call LBV G0.120 – 0.048, was selected for spectroscopy owing to...
A SEARCH FOR RADIO PULSARS IN THE NORTHERN SKY: DISCOVERY OF A PULSAR IN A UNIQUE BINARY SYSTEM
Search Radio pulsar The sky The pulsar. A binary system
2014/12/10
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...

2014/7/18
COLUMBUS, Ohio—A newly discovered planet in a binary star system located 3,000 light-years from Earth is expanding astronomers’ notions of where Earth-like—and even potentially habitable—planets can f...
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...
