Although black holes are usually dark and invisible, occasionally they can produce “fireworks” which light up their surrounding space-me. Sciensts have put tremendous efforts into catching such fireworks for decades, and recently a few sophiscated observaons greatly improved our understanding of black holes. The Event Horizon Telescope has just captured the first-ever image of a massive black hole and its shadow. The Swiſt telescope has allowed us to witness a star wandering too close to a black hole and geng pulled apart. LIGO has detected the gravitaonal waves, or the ripples of space-me, produced by two black holes spiraling towards each other and eventually colliding into one. In this talk, the speaker will discuss the black hole science that has been learnt from these successful endeavors and that will be explored with new telescopes to be launched soon.

About the talk
Black holes are probably the least understood yet the most fascinating celestial objects in our Universe. Although black holes are usually dark and invisible, occasionally they can produce “fireworks” which light up their surrounding space-time. Scientists have put tremendous efforts into catching such fireworks for decades, and recently a few sophisticated observations greatly improved our understanding of black holes. The Event Horizon Telescope has just captured the first-ever image of a massive black hole and its shadow. The Swift telescope has allowed us to witness a star wandering too close to a black hole and getting pulled apart. LIGO has detected the gravitational waves, or the ripples of space-time, produced by two black holes spiraling towards each other and eventually colliding into one.
In this talk, the speaker will discuss the black hole science that has been learnt from these successful endeavors and that will be explored with new telescopes to be launched soon.

Dr Jane Lixin Dai is a theoretical astrophysicist who studies stars, accretion disks, and jets around black holes. She received her BSc from HKUST and PhD from Stanford University. She joined HKU this year as an Assistant Professor.
About the speaker
Black holes are probably the least understood yet
the most fascinating celestial objects in our
Universe. In this talk, Dr Jane Dai will talk about
the “fireworks” produced by black holes which
light up their surrounding space-time.
