8th February 2019 at 14.15 in D101: Peter Johansson

Our next colloquium will be held on 8th February. Our next talk is an inaugural lecture by another new professor in our department, Peter Johansson.

Peter is Professor of Astrophysics here in Helsinki. His research interests range from supermassive black holes to galaxy evolution. He recently received an ERC Consolidator Grant to study the dynamics of supermassive black holes in galactic-scale hydrodynamical simulations and estimate their gravitational wave signatures.

In his talk, titled The birth, life and death of astrophysical black holes, he will discuss exactly those topics.

Here is the abstract of his talk:

Black holes are an important component of the Universe. Stellar-mass black holes are found in abundance throughout galaxies, whereas supermassive black holes reside inĀ the centres of galaxies. In this presentation I will discuss the formation and evolution of different types of black holes and what impact they have on the surrounding galaxy. I will also discuss how black holes and their immediate surroundings can be observed using both electromagnetic and gravitational wave signals. The presentation will be rounded off by a discussion on what is going to happen to black holes in the very distant future and whether they will exist forever.

After the 30 minute talk, there will be a cocktail reception. Welcome!
