Tracking dispersion measure variations of timing array pulsars with the GMRT
Ujjwal Kumar, Yashwant Gupta, Willem van Straten +5
We present the results from nearly three years of monitoring of the variations in dispersion measure (DM) along the line-of-sight to 11 millisecond pulsars using the Giant Metrewav…
PSR J1141-6545: a powerful laboratory of GR and tensor-scalar theories of gravity
J. P. W. Verbiest, N. D. R. Bhat, M. Bailes
Pulsars in close binary systems have provided some of the most stringent tests of strong-field gravity to date. The pulsar--white-dwarf binary system J1141-6545 is specifically int…
Radio emission evolution, polarimetry and multifrequency single pulse analysis of the radio magnetar PSR J1622-4950
L. Levin, M. Bailes, S. D. Bates +11
Here we report on observations of the radio magnetar PSR J1622-4950 at frequencies from 1.4 to 17 GHz. We show that although its flux density is varying up to a factor of ~10 withi…
Multi-wavelength Observations of the Radio Magnetar PSR J1622-4950 and Discovery of its Possibly Associated Supernova Remnant
Gemma E. Anderson, B. M. Gaensler, Patrick O. Slane +29
We present multi-wavelength observations of the radio magnetar PSR J1622-4950 and its environment. Observations of PSR J1622-4950 with Chandra (in 2007 and 2009) and XMM (in 2011)…
