UV/Optical Detections of Candidate Tidal Disruption Events by GALEX and CFHTLS
S. Gezari, S. Basa, D. C. Martin +11
We present two luminous UV/optical flares from the nuclei of apparently inactive early-type galaxies at z=0.37 and 0.33 that have the radiative properties of a flare from the tidal…
Outburst of the 2 s Anomalous X-ray Pulsar 1E 1547.0-5408
J. P. Halpern, E. V. Gotthelf, J. Reynolds +2
Following our discovery of radio pulsations from the newly recognized Anomalous X-ray Pulsar (AXP) 1E 1547.0-5408, we initiated X-ray monitoring with the Swift X-ray Telescope, and…
CCO Pulsars as Anti-Magnetars: Evidence of Neutron Stars Weakly Magnetized at Birth
E. V. Gotthelf, J. P. Halpern
Our new study of the two central compact object pulsars, PSR J1210-5226 (P = 424 ms) and PSR J1852+0040 (P = 105 ms), leads us to conclude that a weak natal magnetic field shaped t…
1E 1547.0-5408: a radio-emitting magnetar with a rotation period of 2 seconds
F. Camilo, S. M. Ransom, J. P. Halpern +1
The variable X-ray source 1E 1547.0-5408 was identified by Gelfand & Gaensler (2007) as a likely magnetar in G327.24-0.13, an apparent supernova remnant. No X-ray pulsations have b…
Neutral Hydrogen Absorption Toward XTE J1810-197: the Distance to a Radio-Emitting Magnetar
Anthony H. Minter, Fernando Camilo, Scott M. Ransom +2
We have used the Green Bank Telescope to measure HI absorption against the anomalous X-ray pulsar XTE J1810-197. Assuming a flat rotation curve, we find that XTE J1810-197 is locat…
X-ray Timing of PSR J1852+0040 in Kesteven 79: Evidence of Neutron Stars Weakly Magnetized at Birth
J. P. Halpern, E. V. Gotthelf, F. Camilo +1
The 105-ms X-ray pulsar J1852+0040 is the central compact object (CCO) in SNR Kes 79. We report a sensitive upper limit on its radio flux density of 12 uJy at 2 GHz using the NRAO…
