NGC 1851A: Revealing an ongoing three-body encounter in a dense globular cluster
A. Dutta, P. C. C. Freire, T. Gautam +16
PSR J05144002A is a binary millisecond pulsar located in the globular cluster NGC 1851. The pulsar has a spin period of 4.99 ms, an orbital period of 18.8 days, and is in a very…
Single pulse polarization study of pulsars B0950+08 and B1642-03: micropulse properties and mixing of orthogonal modes
Shubham Singh, Yashwant Gupta, Kishalay De
We present the results of a high-time resolution polarization study of single pulses from pulsars B0950+08 and B1642-03. Single pulses from pulsar B0950+08 sometimes show isolated…
Discovery of a radio nebula around PSR J0855-4644
C. Maitra, S. Roy, F. Acero +1
We report the discovery of a diffuse radio emission around PSR J0855--4644 using an upgraded GMRT (uGMRT) observation at 1.35 GHz. The radio emission is spatially coincident with t…
Understanding the effects of geometry and rotation on pulsar intensity profiles
R. M. C. Thomas, Y. Gupta, R. T. Gangadhara
We have developed a method to compute the possible distribution of radio emission regions in a typical pulsar magnetosphere, taking into account the viewing geometry and rotational…
On the aberration-retardation effects in pulsars
K. Krzeszowski, D. Mitra, Y. Gupta +3
The magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so--called radius--to--frequency mapping should be reflected in the aberrati…
Results from multi-frequency observations of PSR B0826-34
B. Bhattacharyya, Y. Gupta, J. Gil
We report new results obtained from multi-frequency observations of PSR B0826-34 with the Giant Metrewave Radio Telescope (GMRT). (1) We find no evidence of weak emission during th…
