HALO II: Constraining Hubble constant through continuum delay fitting of Fairall 9
Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +28
The Hubble tension remains one of the most significant unresolved problems in modern cosmology. A key question is whether it may arise from underestimated systematic uncertainties…
Probing the Strong Gravity Region of Black Holes with eXTP
Qingcui Bu, Cosimo Bambi, Lijun Gou +42
We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…
Investigating the consistency of the shape and flux of X-ray reflection spectra in the hard state with an accretion disk reaching close to the black hole
Sudeb Ranjan Datta, Michal Dovčiak, Michal Bursa +3
The observed spectra from black hole (BH) X-ray binaries (XRBs) typically consist of two primary components: multitemperature blackbody (BB) originating from the accretion disk in…
On the search of the elusive Intermediate Mass Black-Holes
M. D. Caballero-Garcia, S. Fabrika, A. J. Castro-Tirado +4
Ultra-Luminous X-ray sources (ULXs) are accreting black holes for which their X-ray properties have been seen to be different to the case of stellar-mass black hole binaries. For m…
Bright X-ray flares from Sgr A*
G. D. Karssen, M. Bursa, A. Eckart +4
We address a question whether the observed light curves of X-ray flares originating deep in galactic cores can give us independent constraints on the mass of the central supermassi…
Failed radiatively Accelerated Dusty Outflow model of the Broad Line Region in Active Galactic Nuclei. I. Analytical solution
B. Czerny, Yan-Rong Li, K. Hryniewicz +6
The physical origin of the Broad Line Region in Active Galactic Nuclei is still unclear despite many years of observational studies. The reason is that the region is unresolved and…
