DOI: 10.1038/s41550-018-0489-x
Abstract: Black hole binary (BHB) systems comprise a stellar-mass black hole and a closely orbiting companion star. Matter is transferred from the companion to the black hole, forming an accretion disk, corona and jet structures. The… read more here.

DOI: 10.1093/mnras/stab1877
Abstract: We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) observations of the inner 3.5×3.5 kpc2 of the radio galaxy Cygnus A to map the gas excitation and kinematics at a spatial resolution of 200 pc. The emission of… read more here.

DOI: 10.1093/mnras/stab2258
Abstract: We present a detailed spectral and timing analysis of Cygnus X-1 with multi-epoch observations, during 2016–2019, by SXT and LAXPC onboard AstroSat. We model the spectra in broad energy range of $0.5\!-\!70.0\, \rm {keV}$ to… read more here.

DOI: 10.1126/science.add5399
Abstract: A black hole x-ray binary (XRB) system forms when gas is stripped from a normal star and accretes onto a black hole, which heats the gas sufficiently to emit x-rays. We report a polarimetric observation… read more here.

DOI: 10.1371/journal.pntd.0010266
Abstract: Laboratory diagnosis of dengue virus (DENV) infection including DENV serotyping requires skilled labor and well-equipped settings. DENV NS1 lateral flow rapid test (LFT) provides simplicity but lacks ability to identify serotype. A simple, economical, point-of-care… read more here.
