The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +95
We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar T…
The second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +97
We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…
Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
Discovery and timing of three millisecond pulsars in radio and gamma-rays with the GMRT and Fermi-LAT
B. Bhattacharyya, J. Roy, T. J. Johnson +14
We performed deep observations to search for radio pulsations in the directions of 375 unassociated Fermi Large Area Telescope (LAT) gamma-ray sources using the Giant Metrewave Rad…
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…
LOFAR Detection of 110-188 MHz Emission and Frequency-Dependent Activity from FRB 20180916B
Z. Pleunis, D. Michilli, C. G. Bassa +32
FRB 20180916B is a well-studied repeating fast radio burst source. Its proximity (~150 Mpc), along with detailed studies of the bursts, have revealed many clues about its nature --…
