The evening will begin with an exciting cutting edge research lecture. Weather permitting, this will be followed by going to our telescope on campus. Or if the weather is not so good we will give you a tour of what you can see in the night sky on clearer nights. Members of our Astrophysics group will also be on hand during the evening to answer your questions.
Colliding black holes and gravitational waves by Dr Fabio Antonini
We are in a similar position as Galileo when he first peered through a telescope: Mankind has found a new way to observe the universe, we can now see gravitational waves! On September 14, 2015, the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) made the first direct measurement of gravitational waves. These waves were generated by two black holes 30 times more massive than the Sun that collided with each other at about 1.3 billion light-years from us. Following this first breakthrough discovery, other 5 detections were made, including the detection of a neutron star merger and its electromagnetic counterpart. I will discuss how this breakthrough detections were made, what they mean, and the future of gravitational wave astrophysics.
19.00 - Doors open
19.15 - Talk starts
19.45 - If clear up to the telescopes for stargazing
If cloudy we'll have a short break and then a talk on what you can see in the night sky this month.
