Abstract The Chandra Deep Fields (CDFs), being a major thrust among extragalactic X-ray
surveys and complemented effectively by multiwavelength observations, have critically …

Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-
Eddington levels and back over timescales of months to years. This provides a unique …

We present the deepest Chandra observation to date of the galaxy M84 in the Virgo Cluster,
with over 840 ks of data provided by legacy observations and a recent 730 ks campaign …

Detection of black holes (BHs) with detached luminous companions (LCs) can be
instrumental in connecting the BH properties with their progenitors since the latter can be …

The corona is an integral component of active galactic nuclei (AGNs) which produces the
bulk of the X-ray emission above 1–2 keV. However, many of its physical properties and the …

Despite their factor of∼ 10 8 difference in black hole mass, several lines of evidence
suggest possible similarities between black hole accretion flows in active galactic nuclei …

ABSTRACT We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) adaptive optics
assisted data cubes to map the stellar population of the inner few hundred parsec of a …

We study the relation between accretion rate (in terms of L/L Edd) and shape of the hard X-
ray spectral energy distribution (namely the photon index Γx) for a large sample of 228 hard …

We present a systematic and uniform analysis of NuSTAR data of a sample of 60 SWIFT BAT-
selected AGNs with 10–78 keV signal-to-noise ratio (S/N)> 50, 10 of which are radio loud …

Using the publicly available eROSITA Final Equatorial Depth Survey (eFEDS) data, we
detected the stacked X-ray emissions at the position of 463 filaments at a significance of …
