Professor Tom Abel will take the audience on a journey through the early stages of the universe, using the latest computer animations of how the first stars formed and died and how stars built up the first galaxies. His work has shown that the first luminous objects in the universe were massive stars, shining one … Continue reading "Public Lecture — Prof. Tom Abel: How Things in the Universe Came About & How They Ended Up Within Us?"
Title: Ionized gas outflows - delayed or no AGN feedback? Abstract: AGN-driven gas outflows are considered as a channel of AGN feedback to star formation activity over galaxy scales. I will present 1) the statistical kinematic study of gas outflows in AGNs and star forming galaxies, 2) the constrains based on the biconnical outflow models, … Continue reading "CRA seminar (Prof. Jong-Hak Woo)"
Title: Revealing black holes hiding in the centers of globular clusters Abstract: It has been long theorized that intermediate-mass black holes (IMBHs) connecting the evolution of stellar-mass and supermassive-black holes should exist. There is mounting evidence suggesting that such black holes can form and may be retained in dense stellar environments. Observationally only upper limits … Continue reading "CRA seminar: Bülent Kiziltan (CfA)"
