Low Frequency Radio Imaging Study of PSR J1818-1607
A. Yadav, M. P. Surnis, B. C. Joshi +1
We report on the low-frequency radio observations of magnetar PSR J18181607 carried out with the upgraded Giant Metrewave Radio Telescope at band 3 (300500 MHz) and band 4 (5…
Pulse Signal Simulation of Pulsars
Jalormi Brahmachari, Mayuresh Surnis
The present thesis is a work in progress on improving the simulation of integrated pulse profiles of pulsars. Pulsars, highly magnetized rotating neutron stars, serve as precise co…
A targeted search for fast radio bursts from magnetars in elliptical galaxies
S. Paine, D. R. Lorimer, S. Sirota +12
Motivated by predictions that globular clusters associated with nearby giant elliptical galaxies are prime environments for detecting fast radio bursts (FRBs) from magnetars, we re…
Profile Reconstruction from Temporally Stable Emission Components for Timing PSR J1713+0747
Shaswata Chowdhury, M. A. Krishnakumar, Sharika Dhakappa +26
The assumption of long-term pulse-profile stability underpins high-precision pulsar timing and forms the basis of pulsar timing array experiments. However, several millisecond puls…
The Indian Pulsar Timing Array Data Release 2: III. Search for a Stochastic Gravitational Wave Background
Hemanga Tahbildar, Kunjal Vara, Mayuresh Surnis +28
We present the first independent search for an isotropic stochastic gravitational wave background in the second data release of the Indian Pulsar Timing Array, comprising of 27 mil…
The Evolution of Nulling in Pulsars
P. R. Brook, J. B. Gibson, M. A. McLaughlin +1
Nulling is a phenomenon where the emission from a pulsar becomes undetectable (or significantly weaker) for a relatively short period of time, followed by a return to a normal emis…
