Detection of X-ray pulsations at the lowest observed luminosity of Be/X-ray binary pulsar EXO 2030+375 with AstroSat
Gaurava K. Jaisawal, Sachindra Naik, Shivangi Gupta +4
We present the results obtained from timing and spectral studies of Be/X-ray binary pulsar EXO 2030+375 using observations with the Large Area Xenon Proportional Counters and Soft…
VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
Multi-wavelength view of the galactic black-hole binary GRS 1716-249
Sandeep K. Rout, Santosh V. Vadawale, Aarthy E. +5
The origins of X-ray and radio emissions during an X-ray binary outburst are comparatively better understood than those of ultraviolet, optical and infrared radiation. This is beca…
The Search for Fast Transients with CZTI
Y. Sharma, A. Marathe, V. Bhalerao +9
The Cadmium Zinc Telluride Imager on AstroSat has proven to be a very effective all-sky monitor in the hard X-ray regime, detecting over three hundred GRBs and putting highly compe…
AstroSat Observations of the first Galactic ULX Pulsar Swift J0243.6+6124
Aru Beri, Sachindra Naik, K. P Singh +11
SwiftJ0243.6+6124, the first Galactic ultra-luminous X-ray pulsar, was observed during its 2017-2018 outburst with \emph{AstroSat} at both sub- and super-Eddington levels of accret…
Blazar OJ 287 After First VHE Activity: Tracking the Re-emergence of the HBL like Component in 2020
Pankaj Kushwaha, Main Pal, Nibedita Kalita +5
We report the re-emergence of a new broadband emission through a detailed and systematic study of the multi-wavelength spectral and temporal behavior of OJ 287 after its first-ever…
Revisiting the spectral and timing properties of 4U 1909+07 with NuSTAR and Astrosat
Gaurava K. Jaisawal, Sachindra Naik, Wynn C. G. Ho +3
We present the results obtained from the analysis of high mass X-ray binary pulsar 4U 1909+07 using NuSTAR and Astrosat observations in 2015 and 2017 July, respectively. X-ray puls…
Probing Nuclear and Circumnuclear Properties of NGC 6300 using X-ray Observations
Arghajit Jana, Arka Chatterjee, Neeraj Kumari +3
We present the results obtained from a detailed X-ray timing and spectral analysis of Seyfert 2 galaxy NGC 6300 by using observations with the {\it Suzaku}, {\it Chandra} and {\it…
AstroSat Observation of Non-Resonant Type-C QPOs in MAXI J1535-571
D. Chatterjee, D. Debnath, A. Jana +8
Galactic transient black hole candidate (BHC) MAXI J1535-571 was discovered on 2017 September 02 simultaneously by {\it MAXI}/GSC and {\it Swift}/BAT instruments. It has also been…
Accretion Flow Evolution of a New Black Hole Candidate MAXI J1348-630 During the 2019 Outburst
Arghajit Jana, Dipak Debnath, Debjit Chatterjee +5
Galactic black hole candidate MAXI~J1348-630 was recently discovered by {\it MAXI} and {\it Swift}/BAT satellites during its first outburst in 2019 January which continued for $\si…
Accretion Flow Properties of XTE J1118+480 During Its 2005 Outburst
Dipak Debnath, Debjit Chatterjee, Arghajit Jana +2
We study spectral and temporal properties of Galactic short orbital period transient black hole XTE J1118+480 during its 2005 outburst using archival data of RXTE PCA and HEXTE ins…
Spectro-polarimetric analysis of prompt emission of GRB 160325A: jet with evolving environment of internal shocks
Vidushi Sharma, Shabnam Iyyani, Dipankar Bhattacharya +3
GRB 160325A is the only bright burst detected by AstroSat CZT Imager in its primary field of view to date. In this work, we present the spectral and polarimetric analysis of the pr…
A retrograde spin of the black hole in MAXI J1659--152
Sandeep K. Rout, Santosh Vadawale, Mariano Méndez
We present the results of spectral analysis of the galactic black-hole binary MAXI J1659--152 in the rising phase of the outburst that lasted for about 65 days starting on 2010 Sep…
Multiwavelength behaviour of the blazar 3C279: decade-long study from -ray to radio
