Quasar UV/X-ray relation luminosity distances are shorter than reverberation-measured radius-luminosity relation luminosity distances
Narayan Khadka, Michal Zajaček, Raj Prince +5
We use measurements of 59/58 quasars (QSOs), over a redshift range , to do a comparative study of the radius--luminosity () and X-rayUV luminosity…
Dust-driven wind as a model of Broad Absorption Line quasars
Mohammad Hassan Naddaf, Mary Loli Martinez-Aldama, Paola Marziani +3
We test a scenario claiming that the broad absorption line (BAL) phenomenon in quasars (QSOs) is not a temporary stage of their life. In this scenario, we see the BAL effect only i…
Dusty plasma in active galactic nuclei
Bożena Czerny, Michal Zajaček, Mohammad-Hassan Naddaf +10
Since many years we know that dust in the form of the dusty-molecular torus is responsible for the obscuration in active galactic nuclei (AGN) at large viewing angles and thus for…
High Eddington quasars as discovery tools: current state and challenges
Swayamtrupta Panda, Paola Marziani
A landmark of accretion processes in active galactic nuclei (AGN) is the continuum originating from a complex structure, i.e., an accretion disk and a corona around a supermassive…
Accretion disks, quasars and cosmology: meandering towards understanding
Bozena Czerny, Shulei Cao, Vikram Kumar Jaiswal +11
As Setti & Woltjer noted back in 1973, quasars could be used to construct the Hubble diagram but the actual application was not that straightforward. It took years to implement the…
The LSST era of supermassive black holes accretion-disk reverberation mapping
Andjelka B. Kovacevic, Viktor Radovic, Dragana Ilic +22
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect an unprecedentedly large sample of actively accreting supermassive black holes with typical accreti…
