Black hole and neutron star X-ray binary systems routinely show quasi-periodic oscillations
(QPOs) in their X-ray flux. Despite being strong, easily measurable signals, their physical …

It is known that the gravitational analog of the Faraday rotation arises in the rotating
spacetime due to the nonzero gravitomagnetic field. In this paper, we show that it also arises …

NuSTAR observed the black hole candidate XTE J1908+ 094 during its 2013 and 2019
outbursts. We use relativistic reflection to measure the spin of the black hole through 19 …

We present a comprehensive multiwavelength spectral analysis of the black hole (BH) X-ray
binary MAXI J1820+ 070 during its 2018 outburst, utilizing AstroSat far-UV, soft X-ray, and …

The physical trigger powering supernovae following the core collapse of massive stars is
believed to involve a neutron star (NS) or a black hole (BH), depending largely on progenitor …

The accreting collapsed object GRO J1655-40 could contain the gravitomagnetic monopole
(GMM), and it was shown to be better described by the Kerr-Taub-NUT (KTN) spacetime …

Black holes (BHs) formed by collapsing and/or merging of magnetized progenitors, have
magnetic fields penetrating the event horizon, and there are several possible scenarios …

Gas fueling AGN (Active Galaxy Nuclei) is now traceable at high-resolution with ALMA
(Atacama Large Millimeter Array) and NOEMA (NOrthern Extended Millimeter Array) …

The physical trigger powering supernovae following the core collapse of massive stars is
believed to involve a neutron star (NS) or a black hole (BH), depending largely on progenitor …

Aims. The prototypical microquasar GRS 1758–258 exhibits large-scale morphological
changes in radio maps over time which have been attributed to the rise of instabilities. Here …
