Spectral Analysis of Cyg X-3 using simultaneous AstroSat and Insight-HXMT Observations
Suraj K. Chaurasia, Gitika Mall, Ruchika Dhaka +2
We present the results from the spectral analysis of Cygnus X-3 using simultaneous data from AstroSat and Insight-HXMT during its soft state. A pure reflection spectrum, including…
Variable Scintillation Arcs of Millisecond Pulsars observed with the Large European Array for Pulsars
R. A. Main, J. Antoniadis, S. Chen +26
We present the first large sample of scintillation arcs in millisecond pulsars, analysing 12 sources observed with the Large European Array for Pulsars (LEAP), and the Effelsberg 1…
Broadband Spectral properties of MAXI J1348--630 using AstroSat Observations
Gitika Mall, Jithesh Vadakkumthani, Ranjeev Misra
We present broadband X-ray spectral analysis of the black hole X-ray binary MAXI J1348--630, performed using five AstroSat observations. The source was in the soft spectral state f…
Detection of quasi-periodic micro-structure in three millisecond pulsars with the Large European Array for Pulsars
K. Liu, J. Antoniadis, C. G. Bassa +24
We report on the detection of quasi-periodic micro-structure in three millisecond pulsars (MSPs), PSRs J1022+1001, J2145-0750 and J1744-1134, using high time resolution data acquir…
Impact of ionization and electron density gradients in X-ray reflection spectroscopy measurements
Gitika Mall, Ashutosh Tripathi, Askar B. Abdikamalov +1
The models currently used for the analysis of the reflection spectra of black holes usually assume a disk with constant ionization and electron density. However, there is some deba…
Double-lens Scintillometry: The variable scintillation of pulsar B1508+55
Tim Sprenger, Robert Main, Olaf Wucknitz +2
We report on observations of PSR B1508+55's scintillation at the Effelsberg 100-m telescope spanning from early 2020 to early 2022. In the autumn of 2020, close to the time the pul…
Modelling annual scintillation arc variations in PSR J1643-1224 using the Large European Array for Pulsars
G. Mall, R. A. Main, J. Antoniadis +25
In this work we study variations in the parabolic scintillation arcs of the binary millisecond pulsar PSR J1643-1224 over five years using the Large European Array for Pulsars (LEA…
Broadband Spectral and Timing Properties of MAXI J1348-630 using AstroSat and NICER Observations
V. Jithesh, Ranjeev Misra, Bari Maqbool +1
We present broadband X-ray spectral-timing analysis of the new Galactic X-ray transient MAXI~J1348--630 using five simultaneous {\it AstroSat} and {\it NICER} observations. Spectra…
Measuring Interstellar Delays of PSR J0613-0200 over 7 years, using the Large European Array for Pulsars
R. A. Main, S. A. Sanidas, J. Antoniadis +19
Using data from the Large European Array for Pulsars (LEAP), and the Effelsberg telescope, we study the scintillation parameters of the millisecond pulsar J0613-0200 over a 7 year…
Spectral and Timing Properties of the Galactic X-ray transient Swift~J1658.2--4242 using Astrosat Observations
V. Jithesh, Bari Maqbool, Ranjeev Misra +3
We present the X-ray timing and spectral analysis of the new Galactic X-ray transient Swift J1658.2-4242 observed with LAXPC and SXT instruments onboard {\it Astrosat}. We detect p…
