---+ January 20, 2023 7-9PM *Event Type*: [[PublicLectures][Lecture and Stargazing]]<br> *Title*: Fireworks from Black Holes Devouring Stars<br> *Lecturer*: Yuhan Yao<br> *Position*: Phd Candidate<br> *Institution*: Caltech<br> *Abstract*: <br> Most galaxies in the universe are thought to contain a supermassive black hole. While these black holes themselves do not emit light, they can be "awakened" when a star gets too close and is torn apart by their powerful gravitational forces. From start to finish, a black hole takes a couple of months to fully consume a star, all the while producing visual fireworks across the electromagnetic spectrum. I will talk about how astronomers search for these "tidal disruption events", and what we have learned about black holes as they manipulate nearby material to create new physical features. <br><br> <img src="%ATTACHURLPATH%/20230120V.jpg" alt="20230120V.jpg" width="768" height="1024" />
