Monthly meeting

October 3, 2019 @ 7:00 pm – 9:00 pm
Fairview Community Center
1910 County Road B West
Roseville, MN 55113


Speaker: Prof. Tom Jones (Minnesota Institute of Astrophysics)

Topic: Active Galactic Nuclei in the 21st Century

“The fact that the nuclei of some galaxies can outshine the entire remaining galaxy and expel huge amounts of kinetic energy has been recognized since the 1960s; That the engines for these behaviors are “supermassive black holes”, sometimes exceeding a billion times the mass of our sun, has been recognized since the 1970s. How these massive monsters get fed and exactly what makes them behave the way they do remains a serious challenge to understand even towards the end of the second decade of the 21st Century. In this talk I will outline the basic picture as we understand it and touch on some of the key still-unsolved puzzles.”

Monthly meetings are open to all – you needn’t be an MAS member to attend. These meetings normally take place the first Thursday of each month at the Fairview Community Center in Roseville (“Great Room”). Monthly meetings start at 7:00 p.m. and last about two hours.

Each meeting features Board member introductions, general announcements, “Better Know a Constellation”, normally presented by a member, main speaker (around 45 minutes duration) and an after-meeting social gathering. Society business is occasionally transacted as needed.
