Samhain agus Science: The Most Massive Black Holes in the Stellar Graveyard

The Dublin Institute for Advanced Studies (DIAS) conducts advanced studies exploring big questions of the 21stcentury and beyond. Its research gains insights into Celtic society and its legacy; progresses our understanding of our island, our planet and the universe; and deciphers the underpinning mathematical principles of nature.The Institute leads Ireland’s participation in a number of international and global initiatives that focus on big unanswered questions for mankind.When it was founded in 1940, DIAS was the world’s second-only institute for advanced studies – and the first such institute in Europe. For 80 years, it has pushed the boundaries of discovery and, today, it is a globally-embedded institution that attracts high-calibre researchers from all over the world in its core disciplines of Celtic Studies, Theoretical Physics, Astrophysics and Geophysics. DIAS Dunsink Observatory is a designated European site of historical significance for physics.

Join us for our final talk of Samhain agus Science 2021 where Dr Erin Higgins looks at end of life black holes.

Samhain agus Science 2021

Samhain agus Science is an annual initiative of the Dublin Institute for Advanced Studies taking place each year during Halloween.

The most massive stars in our Universe collapse to form black holes at the end of their lives. In this talk we will look at how we can detect these massive black holes as they merge causing ripples in space-time. The stellar graveyard is populated with black holes of different masses, but there exists an upper mass limit where stars rip themselves apart in cataclysmic explosions, leaving no remnant behind. We will look at the most massive stellar black hole ever detected and explore how it may have formed right at the boundary of this upper limit.About our SpeakerErin is originally from Derry, where she joined an astronomy club at her local school Thornhill College, before undertaking work experience at the Armagh Observatory. After completing a bachelors degree in Physics with Astrophysics at Queen’s University Belfast, she obtained a Postgraduate Certificate in Education teaching secondary school Physics. She went on to do her PhD at the Armagh Observatory &amp; Planetarium in conjunction with DIAS, as part of a cross-border collaboration with a Lindsay scholarship, studying the lives of massive stars. She now works as a Postdoctoral researcher at the Armagh Observatory focussing on black hole progenitors and the most massive stars. She also enjoys working on outreach activities and careers events at the Planetarium.This will be an online event hosted via Zoom. Registration is required. Attendance links will be delivered via email on the day of the event.
