Cosmic-ray positron fraction measurement from 1 to 30 GeV with AMS-01
01 Collaboration
A measurement of the cosmic ray positron fraction e+/(e+ + e-) in the energy range of 1-30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during…
Discovery of Radio Emission from Transient Anomalous X-ray Pulsar XTE J1810-197
J. P. Halpern, E. V. Gotthelf, R. H. Becker +2
We report the first detection of radio emission from any anomalous X-ray pulsar (AXP). Data from the Very Large Array (VLA) MAGPIS survey with angular resolution 6" reveals a point…
Hubble Advanced Camera for Surveys Observations of the z=6.42 Quasar SDSS 1148+5251: A Leak in the Gunn-Peterson Trough
Richard L. White, Robert H. Becker, Xiaohui Fan +1
The Hubble Advanced Camera for Surveys has been used to obtain a narrow-band image of the weak emission peak seen at lambda=7205 A in the Gunn-Peterson Ly beta absorption trough of…
The Reddest Quasars
Michael D. Gregg, Mark Lacy, Richard L. White +4
In a survey of quasar candidates selected by matching the FIRST and 2MASS catalogs, we have found two extraordinarily red quasars. FIRST J013435.7-093102 is a 1 Jy source at z=2.21…
