Multi-frequency integrated profiles of pulsars
Simon Johnston, Aris Karastergiou, Dipanjan Mitra +1
We have observed a total of 67 pulsars at five frequencies ranging from 243 to 3100 MHz. Observations at the lower frequencies were made at the Giant Metre Wave Telescope in India…
On the Subpulse Modulation, Polarization and Subbeam Carousel Configuration of Pulsar B1857--26
Dipanjan Mitra, Joanna M Rankin
New GMRT observations of the five-component pulsar B1857--26 provide detailed insight into its pulse-sequence modulation phenomena for the first time. The outer conal components ex…
The effect of Pulse profile evolution on Pulsar Dispersion Measure
Amrit Lal Ahuja, Dipanjan Mitra, Yashwant Gupta
In an earlier paper (Ahuja, et al, 2005), based on simultaneous multi-frequency observations with the Giant Metrewave Radio Telescope (GMRT), we reported the variation of pulsar di…
Absolute Broadband Polarization Behaviour of PSR B0329+54: A Glimpse of the Core Emission Process
Dipanjan Mitra, Joanna M. Rankin, Yashwant Gupta
In this paper we report multifrequency single pulse polarization observations of the PSR B0329+54 normal mode using the Giant Meterwave Radio Telescope at 325 and 610 MHz and the E…
Filling factors and scale heights of the DIG in the Milky Way
E. M. Berkhuijsen, D. Mitra, P. Mueller
The combination of dispersion measures of pulsars, distances from the model of Cordes and Lazio (2002) and emission measures from the WHAM survey enabled a statistical study of ele…
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…
