Discovery of an Intermittent Pulsar: PSR J1839+15
M. P. Surnis, B. C. Joshi, M. A. McLaughlin +1
We report the discovery of a new pulsar PSR J1839+15, having a period of 549 ms and a DM of 68 pc-cm^-3. We also present its timing solution and report the intermittent behaviour o…
Modal Sequencing and Dynamic Emission Properties of an 8-hour GMRT Observation of Pulsar B1822-09
Crystal Latham, Dipanjan Mitra, Joanna Rankin
The research presented here examines an 8-hour observation of pulsar B1822-09,taken by the Giant Metrewave Radio Telescope. B1822-09 has been known to exhibit two stable emission m…
Observations of four glitches in the young pulsar J1833-1034 and study of its glitch activity
Jayanta Roy, Yashwant Gupta, Wojciech Lewandowski
We present the results from timing observations with the GMRT of the young pulsar J1833-1034, in the galactic supernova remnant G21.5-0.9. We detect the presence of 4 glitches in t…
A survey of nulling pulsars using the Giant Meterwave Radio Telescope
Vishal Gajjar, B. C. Joshi, M. Kramer
Several pulsars show sudden cessation of pulsed emission, which is known as pulsar nulling. In this paper, the nulling behaviour of 15 pulsars is presented. The nulling fractions o…
Three-dimensional Evolution of Solar Wind during Solar Cycles 22-24
P. K. Manoharan
This paper presents the analysis of 3D evolution of solar wind density turbulence and speed at various levels of solar activity between solar cycles 22 and 24. The solar wind data…
