The Reawakening of 4U 1755-338 after 25 Years of Quiescence: Spectro-temporal Analysis Using Multi-instrument X-ray Data
Geethu Prabhakar, Samir Mandal
The black hole X-ray binary 4U 1755338 underwent an outburst in 2020 after 25 years of quiescence. The comprehensive spectral analysis revealed that the system has a low interst…
Wideband Study of the Brightest Black Hole X-ray Binary 4U 1543-47 in the 2021 Outburst: Signature of Disk-Wind Regulated Accretion
Geethu Prabhakar, Samir Mandal, Bhuvana G. R. +1
A comprehensive wideband spectral analysis of the brightest black hole X-ray binary 4U during its 2021 outburst is carried out for the first time using NICER, NuSTAR, and…
Accretion Scenario of MAXI J1820+070 during 2018 Outbursts with Multi-mission Observations
Geethu Prabhakar, Samir Mandal, Athulya M. P +1
We present a comprehensive spectral and temporal study of the black hole X-ray transient MAXI J1820+070 during its outbursts in 2018 using Swift/XRT, NICER, NuSTAR and AstroSat obs…
Properties of two-temperature magnetized advective accretion flow around rotating black hole
Indu K. Dihingia, Santabrata Das, Geethu Prabhakar +1
We study the two-temperature magnetized advective accretion flow around the Kerr black holes. During accretion, ions are heated up due to viscous dissipation, and when Coulomb coup…
Thermodynamics and Geometrothermodynamics of Charged black holes in Massive Gravity
Jishnu Suresh, C P Masroor, Geethu Prabhakar +1
The objective of this paper is to study the thermodynamics and thermodynamic geometry of charged de-Sitter and charged anti de-Sitter black hole solutions in massive gravity. We st…
