Lecture: Weds 31st October - Dr. Marc Sarzi (AOP) - "Supermassive Black Holes, the DNA of galaxies?"

Dr Marc Sarzi

Abstract: Supermassive black holes, million to billion times more massive than the Sun, are now believed to lurk at the centre of every galaxy. Furthermore, it would appear that supermassive black holes "know" in which galaxy they live, as bigger galaxies contain bigger supermassive black holes and vice versa. This suggests that the formation of galaxies and the growth of supermassive black holes are tightly linked, which is surprising considering that despite their tremendous mass such black holes are still much smaller than their host galaxies, just like DNA molecules to a human body.

Lecture Weds 17th Oct - Prof Gerry Doyle (AOP) - "The Probability of a Doomsday Solar Superflare: Fact or Fiction?"

Prof Gerry Doyle MRIA

Here's Prof Doyle with the synopsis of his talk.......

"The first part of the talk is on solar flares, how they occur, their energy, etc .. then I go into stellar flares and show data from Kepler on flares from solar-like stars and discuss whether such super-flares could occur on the Sun .. i include spot data over the past 300 years .. what is happening now, predications for the next cycle, how a super-flare could occur on the Sun .. plus observations from 900 years ago."

IAA Lecture Weds 3rd October - Prof Luke Drury (DIAS) - "Multimessenger Astronomy Comes of Age"

Prof Luke Drury

Throughout most of its long history astronomy has been based on the study of light from the stars and other celestial objects. In the language of physics this is photonic astronomy, the photon being the quantum mechanical particle of light. Yet at least two other astronomies are possible according to standard physics. The graviton, the particle asssociated with gravity, and the neutrino, associated with the weak force, share the property of being electrically neutral and stable and can thus propagate undeflected over cosmic distances.
