Tides in the Clouds
Tides operate at many levels,
from the beach where you take your holiday, to interactions between the most
massive structures in the universe. Such large scale interactions between
galaxies can sometimes trigger huge waves of starbirth,
producing large numbers of massive stars and their evolved products neutron
stars and black holes. This talk will describe why we believe such an event
took place 200 million years ago in the Small Magellanic Cloud (a satellite
galaxy to the Milky Way), and how X-ray telescopes are now discovering a huge
nest of neutron stars produced from those tidal interactions. Along the way we
will look at the observational history of the SMC from the first drawings by
John Herschel done in Cape Town, to a massive X-ray survey just completed last
year

"The Violent Universe - the search for
Black Holes"
Black holes represent some
of the most extreme conditions that exist anywhere in the Universe. Material
falling on to a Black Hole gets heated up to 10-100 million degrees before
being falling inside the Event Horizon. This talk presents the fundamental
properties of Black Holes in terms that are easily understood. It also presents
the overwhelming observational evidence for their existence.
