The discovery of PSR J1833-1034 : the pulsar associated with the supernova remnant G21.5-0.9
Y. Gupta, D. Mitra, D. A. Green +1
We report the discovery of a young pulsar associated with the supernova remnant G21.5-0.9, using the Giant Metrewave Radio Telescope (GMRT) located near Pune, India. Discovered at…
The PSR J0514-4002A binary system in NGC 1851
P. C. C. Freire, Y. Gupta, S. M. Ransom +1
Using the Giant Metrewave Radio Telescope (GMRT), we have discovered PSR J0514-4002A, a binary millisecond pulsar in the globular cluster NGC 1851. This pulsar has a rotational per…
Constraints on Interstellar Plasma Turbulence Spectrum from Pulsar Observations at the Ooty Radio Telescope
N. D. Ramesh Bhat, Yashwant Gupta, A. Pramesh Rao
Refractive Interstellar Scintillation (RISS) effects on pulsar signals are powerful techniques for discriminating between different models that have been proposed for the power spe…
Pulsar Scintillation Studies and Structure of the Local Interstellar Medium
N. D. Ramesh Bhat, Yashwant Gupta, A. Pramesh Rao +1
Results from new observations of pulsars using the Ooty Radio Telescope (ORT) are used for investigating the structure of the Local Interstellar Medium (LISM). The observations sho…
Detection of new emission components in PSR B0329+-54
R. T. Gangadhara, Y. Gupta, D. R. Lorimer
To study the structure of emission beam, we have analysed the single pulse data of PSR B0329+-54 at 325 and 606 MHz. In order to unambiguously detect the weak emission components,…
Multiple Imaging of PSR B1133+16 by the ISM
Yashwant Gupta, N. D. Ramesh Bhat, A. Pramesh Rao
Refraction of pulsar radiation by electron density irregularities in the interstellar medium sometimes produces multiple imaging of pulsars which can lead to periodic oscillations…
