Stas Babak (APC), 11am on zoom

In this talk I introduce GW event GW190521 and describe its properties. 
Then I will assume its association with the optical flare observed by the Zwicky Transient 
Facility in an Active Galactic Nucleus (AGN). After giving some plausible explanation of this association, 
I will move to possibility observing GW190521-like event(s) with LISA. LISA should detect few tens 
of stellar-mass black hole binaries few years before the 3rd generation of ground-based GW 
interferometers observes their merger. Assuming that some of these binaries are embedded in 
gaseous circum-nuclear disk in AGN, we will discuss potentially detectable features in GW signal due to 
interaction of binary with the gas and with a massive black hole in the galactic centre.
