Spectropolarimetric study of 4U 163047 in Steep Power law state with IXPE and NICER
Divya Rawat, Akash Garg, Mariano Méndez
We probe the spectropolarimetric properties of the black-hole binary source 4U 163047 in the steep power law state. We detect a significant polarization fraction of 7 % at…
Testing the dynamic origin of Quasi-periodic Oscillations in MAXI J1535-571 and H 1743-322
Divya Rawat, Nazma Husain, Ranjeev Misra
We investigate spectro-temporal properties for two black hole X-ray binary sources, MAXI J1535571 and H 1743322, during their hard and hard-intermediate states. For MAXI J153…
Symmetry breaking and structure instability in ultra-thin 2H-TaS2 across charge density wave transition
Divya Rawat, Aksa Thomas, Ajay Soni
Ultra-thin 2D materials have shown complete paradigm shift of understanding of physical and electronic properties because of confinement effects, symmetry breaking and novel phenom…
Evolution of QPOs in GX 339-4 and EXO 1846-031 with Insight-HXMT and NICER
Zuobin Zhang, Honghui Liu, Divya Rawat +6
We conduct a spectral and timing analysis of GX 339-4 and EXO 1846-031 with the aim of studying the evolution of Type-C QPOs with spectral parameters. The high cadence data from In…
Flux-resolved Spectropolarimetric Evolution of the X-Ray Pulsar Hercules X-1 Using IXPE
Akash Garg, Divya Rawat, Yash Bhargava +2
We conduct a spectro-polarimetric study of the accreting X-ray pulsar Hercules X-1 using observations with the Imaging X-ray Polarimetry Explorer (IXPE). IXPE monitored the source…
Detection of X-ray polarized emission and accretion-disk winds with IXPE and NICER in the black-hole X-ray binary 4U 1630-47
Divya Rawat, Akash Garg, Mariano Méndez
We detect a high level of polarization in the X-ray emission of the black-hole binary 4U 1630-47 in an observation with the Imaging X-ray Polarimetry Explorer. The 2-8 keV polariza…
A NICER look at the jet-like corona of MAXI J1535-571 through type-B quasi-periodic oscillations
Yuexin Zhang, Mariano Méndez, Federico García +7
MAXI J1535-571 is a black-hole X-ray binary that in 2017 exhibited a very bright outburst which reached a peak flux of up to 5 Crab in the 2-20 keV band. Given the high flux, sever…
The comptonizing medium of the black-hole X-ray binary MAXI~J1535571 through type-C quasi-periodic oscillations
Divya Rawat, Mariano Méndez, Federico García +7
We present a detailed spectral and temporal analysis of the black-hole candidate MAXI~J1535571 using NICER observations in September and October 2017. We focus specifically on o…
Anisotropic Light-Matter Interactions in Single Crystal Topological Insulator Bismuth Selenide
Divya Rawat, Aditya Singh, Niraj Kumar Singh +1
Anisotropy of light-matter interactions in materials give remarkable information about the phonons and their interactions with electrons. We report the angle-resolved polarized Ram…
