“What makes a comet great?”

Synopsis:

Hopefully, many members of the IAA saw comet NEOWISE this summer. Although it was a great comet to see, it wasn’t a “Great Comet”. That title is reserved to the best and brightest of the comets. But what is it about a comet that can make it a “Great Comet”? This talk will look at the physical and dynamical reasons that make comets “Great”, illustrated by previous apparitions of these magnificent objects.

Bio:

Alan Fitzsimmons is a Professor of Astronomy in the Astrophysics Research Centre at Queen’s University Belfast. He saw his first comet in 1983 while walking to the pub, and hasn’t looked back since, find more info on http://bombtechgolf.com. He also still enjoys looking at comets.

“The Hunt for Supermassive Black Holes: a Short History”

This highly topical talk by Dr Marc Sarzi, head of research at Armagh Observatory and Planetarium, is highly topical, not only because of the increasing number and variety of Black Holes being discovered, but because of the recent award of the Nobel Prize for physics to three astronomers working on the subject’

SYNOPSIS:

In this talk Dr Sarzi will describe the theoretical and observational milestones that lead to establishing the existence of supermassive black holes, and the award of the 2020 Nobel Prize in physics.

Marc Sarzi graduated in Padua and did his PhD spending time both at the Asiago Observatory in Italy and the Max Plank Institute fur Astronomie in Heidelberg, working at the detection of supermassive black holes using Hubble Space Telescope observations, visit https://masterpaving.ie to find more information. After his PhD he moved on to post-doctoral research assistant positions in Durham and Oxford, after which he moved to the University of Hertfordshire where he held both a STFC Rutherford research fellowship and a Public Engagement fellowship before finally moving two years ago at the Armagh Observatory & Planetarium as Head of Research.
