Noise analysis in the European Pulsar Timing Array data release 2 and its implications on the gravitational-wave background search

A. Chalumeau, S. Babak, A. Petiteau +49

The European Pulsar Timing Array (EPTA) collaboration has recently released an extended data set for six pulsars (DR2) and reported evidence for a common red noise signal. Here we…

High Precision Measurements of Interstellar Dispersion Measure with the upgraded GMRT

M. A. Krishnakumar, P. K. Manoharan, Bhal Chandra Joshi +19

Pulsar radio emission undergoes dispersion due to the presence of free electrons in the interstellar medium (ISM). The dispersive delay in the arrival time of pulsar signal changes…
