Stars in galactic nuclei interrelation with massive black holes (GM24-10599M)

The goal of the project is to study the mutual interaction between stars and supermassive black holes (SBHs) in galactic nuclei. Previously, we showed, they inevitably change the accretion state of the SBH. Traditional unified model...

Geometrical properties of the accretion disc corona in Active Galactic Nuclei (GA17-02430S)

One of the main characteristics of the Active Galactic Nuclei (AGN) is their large flux variability in the X-ray energy domain, when the source can change its photon flux by order of magnitude on time-scales of days or even...

Galactic gastronomy Green Peas and Blueberries (GA22-22643S)

. There are two main scenarios to explain this - active galactic nuclei or a large amount Green Pea galaxies without any indication of AGN activity from their optical spectra......

Extragalactic astrophysics Stellar dynamics in galactic nuclei (GP205/02/P089)

- a galactic nucleus. Our main goal is to discuss the structure and the evolution of dense strongactivity. We will consider a model which is based on a conventional view of galactic nuclei with accreting black holes. The c...

Probing Strong Gravity by Black Holes Across the Range of Masses (7E13012)

As a leader of RTD workpackages WP2, WP10 and WP15 our team will: develop new tools for modelling reflection from neutral and ionized black-hole accretion discs, accurately model thermal spectra of black-hole accretion discs in soft state over a rang...

Weather effects in using disk continuum time delays in active galactic nuclei to measure the expansion rate of the Universe (GF23-04053L)

The goal of the project is to change the multiwavelength continuum time delays in active galactic nuclei (AGN) into an efficient tool to measure the expansion rate of the Universe. Previously we successfully used the method...
