Journal ArticleDOI
Transient pulsed radio emission from a magnetar
Fernando Camilo,Scott M. Ransom,Jules P. Halpern,John Reynolds,David J. Helfand,Neil Zimmerman,John Sarkissian +6 more
TL;DR: It is shown that XTE J1810 - 197 emits bright, narrow, highly linearly polarized radio pulses, observed at every rotation, thereby establishing that magnetars can be radio pulsars.
Journal ArticleDOI
Measurement and correction of variations in interstellar dispersion in high-precision pulsar timing
Michael Keith,William A. Coles,Ryan Shannon,George Hobbs,Richard N. Manchester,Matthew Bailes,N. D. R. Bhat,N. D. R. Bhat,Sarah Burke-Spolaor,D. J. Champion,A. Chaudhary,Aidan Hotan,Jonathan Khoo,Jonathon Kocz,Jonathon Kocz,Stefan Oslowski,Stefan Oslowski,Vikram Ravi,Vikram Ravi,John Reynolds,John Sarkissian,W. van Straten,D. R. B. Yardley,D. R. B. Yardley +23 more
TL;DR: In this article, the authors demonstrate that simple algorithms to correct for interstellar dispersion can attenuate signals of interest to pulsar timing arrays, such as that induced by a gravitational wave background.
Journal ArticleDOI
Detection of 107 glitches in 36 southern pulsars
M. Yu,M. Yu,Richard N. Manchester,George Hobbs,Simon Johnston,Victoria M. Kaspi,Michael Keith,Andrew Lyne,Guojun Qiao,Vikram Ravi,Vikram Ravi,John Sarkissian,Ryan Shannon,R. X. Xu +13 more
TL;DR: In this article, the Parkes 64m radio telescope for 165 pulsars between 1990 and 2011 have been searched for period glitches, both for the previously knownand the new glitch detections, were measured by fitting the timing residual data.
Journal ArticleDOI

TL;DR: Data show that there was new material after impact that was compositionally different from that seen before impact, and the ratio of dust mass to gas mass in the ejecta was much larger than before impact.
