Tracking pulsar dispersion measures using the GMRT
A. L. Ahuja, Y. Gupta, D. Mitra +1
In this paper, we describe a novel experiment for the accurate estimation of pulsar dispersion measures using the Giant Metre-wave Radio Telescope. This experiment was carried out…
The Frequency Evolution of Interstellar Pulse Broadening from Radio Pulsars
O. Loehmer, D. Mitra, Y. Gupta +2
In this paper we report multi-frequency measurements of pulse broadening times (tau_d) for nine medium dispersion measure (DM pc cm) pulsars observed over…
Unraveling the drift behaviour of the remarkable pulsar PSR B0826-34
Y. Gupta, J. Gil, J. Kijak +1
We present new results from high sensitivity GMRT observations of PSR B0826-34. We provide a model to explain the observed subpulse drift properties of this pulsar, including the a…
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…
GMRT Discovery of A Millisecond Pulsar in a Very Eccentric Binary System
Paulo C. Freire, Yashwant Gupta, Scott M. Ransom +1
We report the discovery of the binary millisecond pulsar J0514-4002A, which is the first known pulsar in the globular cluster NGC 1851 and the first pulsar discovered using the Gia…
