Poštovani,

U biblioteci Astronomske opservatorije biće održan naučno-stručni skup u
utorak 19. jula sa početkom u 13h (uživo).

Tema: Investigating our variable Universe: from AGN variability to the
quest for exoplanets

Izlagač: Dr. Lia F. Aleksandrović-Sartori, ETH Zurich, Institute for
Particle Physics and Astrophysics

Apstrakt:
-----------
Variability is ubiquitous in our Universe and can be observed or inferred
in different objects at all timescales, from minutes to billions of years.
In this talk I will illustrate how spatially resolved optical spectroscopy,
combined with high quality X-ray data, can be used to probe active galactic
nuclei (AGN) variability on > 10^4 yr timescales. I will then present a
framework which allows us to test if and how variability in different AGN
and at different timescales can be linked and explained based on the
distribution of the Eddington ratio (ER) among the galaxy population, and
discuss possible applications of this model. In the second part of the talk
I will show how techniques similar to those applied to AGN variability can
enable us to search for extrasolar planets, and how satellites usually
devoted to exoplanets search can be used to investigate AGN variability.
