Distinct Fe-K Line Complexes in MAXI J1744-294 Revealed by XRISM High-Resolution Spectroscopy
Kaushik Chatterjee, Santanu Mondal, Biswaraj Palit +7
The newly discovered Galactic transient MAXI J1744-294 went into its first X-ray outburst in 2025. We study the spectral properties of this source in the 2-10 keV energy band durin…
Dispersion relation for the linear theory of relativistic Rayleigh Taylor instability in magnetized medium revisited
Qiqi Jiang, Guang-Xing Li, Chandra B. Singh
The Rayleigh-Taylor instability (RTI) arises at the interface between two fluids of different densities, notably when a heavier fluid lies above a lighter one in an effective gravi…
Interpreting the Spectro-Temporal Properties of the Black Hole Candidate Swift J151857.0-572147 during its First Outburst in 2024
Kaushik Chatterjee, S. Pujitha Suribhatla, Santanu Mondal +1
The transient Galactic black hole candidate Swift J151857.0-572147 went through an outburst in March 2024 for the first time. Using publicly archived {\it Insight}-HXMT data, we ha…
{\it Insight}-HXMT View of the BHC Swift J1727.8-1613 during its outburst in 2023
Kaushik Chatterjee, Santanu Mondal, Chandra B. Singh +1
The transient Galactic black hole candidate Swift\,J1727.8-1613 went through an outburst for the very first time in August 2023 and lasted for almost 6 months. We study the timing…
The first detection of X-ray polarization in a newly discovered Galactic transient Swift\,J151857.0-572147
Santanu Mondal, S. Pujitha Suribhatla, Kaushik Chatterjee +2
We study the spectro-polarimetric properties of a newly discovered black hole X-ray binary Swift\,J151857.0-572147 jointly using {\it IXPE} and {\it NuSTAR} observations during Mar…
