Evidence of Orbital Evolution of Gigahertz-Peaked Spectra in Binary Millisecond Pulsar
Rahul Sharan, Bhaswati Bhattacharyya
We present the first systematic investigation of the continuous orbital evolution of the Gigahertz-Peaked Spectum turnover frequency () in the binary millisecond pulsar,…
Temporal Variations in Pulsar Spectro-Polarimetry: Findings from millisecond pulsar J2144-5237 using Parkes UWL receiver
Rahul Sharan, Bhaswati Bhattacharyya, Simon Johnston +2
While the temporal variations of the spectro-polarimetric nature of pulsars remains unexplored, this investigation offers significant potential for uncovering key insights into pul…
Deciphering Profile Stability in Millisecond Pulsars: Timescales, Frequency Evolution, and Implications on Emission Mechanisms
Ankita Ghosh, Bhaswati Bhattacharyya, Rahul Sharan +3
Pulse profile stability in millisecond pulsars (MSPs) is a key factor in achieving high-precision timing essential for detecting nanohertz gravitational waves with Pulsar Timing Ar…
Unveiling Low-Frequency Eclipses in Spider MSPs using wideband GMRT Observations
Sangita Kumari, Bhaswati Bhattacharyya, Devojyoti Kansabanik +3
Eclipses of radio emission have been reported for ~ 58 spider millisecond pulsars (MSP), of which only around 19% have been extensively studied. Such studies at low frequencies are…
Unveiling frequency-dependent eclipsing in spider millisecond pulsars using broadband polarization observations with the Parkes
Sangita Kumari, Bhaswati Bhattacharyya, Rahul Sharan +6
This study presents an orbital phase-dependent analysis of three black widow spider millisecond pulsars (BW MSPs), aiming to investigate the magnetic field within the eclipse envir…
Flux Density Stability and Temporal Changes in the Spectra of Millisecond Pulsars using the GMRT
Rahul Sharan, Bhaswati Bhattacharyya, Sangita Kumari +2
This paper presents an investigation of spectral properties of 10 millisecond pulsars (MSPs) discovered by the uGMRT, observed from 2017-2023 using band 3 (300-500 MHz) and 4 (550-…
The GMRT High-Resolution Southern Sky Survey for pulsars and transients -- VII: Timing of Spider MSP J1242-4712, A Bridge Between Redback and Black Widow Pulsars
Ankita Ghosh, Bhaswati Bhattacharyya, Andrew Lyne +7
We present the timing solution for the 5.31-ms spider millisecond pulsar (MSP) J1242-4712, discovered with the GMRT. PSR J1242-4712 orbits a companion of minimum mass 0.08 M$_{\odo…
First systematic study reporting the changes in eclipse cut-off frequency for pulsar J1544+4937
Sangita Kumari, Bhaswati Bhattacharyya, Rahul Sharan +3
We present results from a long-term monitoring of frequency dependent eclipses of the radio emission from PSR J1544+4937 which is a ``black widow spider'' millisecond pulsar (MSP)…
