Science Public Lecture May flyer
Black Hole Feedback with Dr Helen Russell
Join us for on Thursday 21 May for our Science Public Lecture, with Dr Helen Russell from the 海角黑料’s Faculty of Science.
Over the last 30 years, `feedback' has been the single most important discovery in our understanding of structure in the Universe (NASA Decadal Review 2021). Gravity pulls mass together to form stars and galaxies, like our own Milky Way. But, if our models only include gravity, galaxies grow far too big and form far too many stars. Additional physics is needed to explain the galaxies we see around us.
The energetic processes around black holes, known collectively as feedback, are thought to be the missing mechanism driving gas back out of massive galaxies and slowing their growth over cosmic time.
Developed by NASA and the Japanese Space Agency at a cost of US$300M, the newly-launched XRISM satellite is now finally revealing the vast, feedback-driven gas flows that are shaping galaxies.
As the only UK-based astronomer awarded observing time in XRISM's first call for science programs, Dr Russell will present the exciting new results from this observatory and the incredible potential of the European Space Agency's future NewAthena mission
No registration is required for this event. This lecture is part of our monthly Science Public Lecture series, and everyone is welcome to join.
