Shedding Light on the Dark Matter of the Universe

Dr. Marie-Cécile Piro                         

Astronomical and cosmological observations strongly suggest that most of the matter in the Universe is non-luminous and made of an unknown substance called dark matter (DM). Even if its direct detection escaped to the scientific community in our time, DM is a fundamental concept that could explain how our Universe formed and helps to restore the mismatch between what we observed and what we predicted.  Over the last decade, dark matter detection techniques have been improving a lot pushing the sensitivity to unprecedented levels. After giving an introduction of the evidences of dark matter, the diverse experimental techniques to detect dark matter will be presented. The current and future stage of the international collaborations in the context of the global dark matter search will also be discussed.

The Hubble Space Telescope was launched 28 years ago in 1990. After overcoming problems caused by a defective main mirror, Hubble has made discoveries that have revolutionized our view of the universe we live in. This talk will cover the history of HST based on a history book the speaker is writing for NASA.

RASC Regular Meeting December 10, 2018, Unravelling Star Formation

Unravelling Star Formation

Stars form in the coldest, densest collections of interstellar gas, called molecular clouds.  Observations in the Milky Way and nearby galaxies show that molecular cloud mass is strongly related to the rate stars form. This relationship is rather surprising since it continues over a range of galaxy types and environments, suggesting that stars form through a common process. What controls that process, however, remains elusive. I will present recent observations of molecular clouds taken by new, state-of-the-art radio telescopes that are beginning to unravel the process of star formation. The quality of these observations is an enormous improvement from previous observations and has lead to an on-going revolution in our understanding of star formation.

Dr. Mathieu Dumberry

The whole of the Moon: a journey to the center of our closest neighbor

The Lunar Interior

We know many things about our closest neighbor, the Moon.  Yet, its deepest part, close to the center, remains not well known.  In this presentation, I will give a brief overview of what we know about the Moon and its interior and how this information is obtained.  I will also show examples of the work that we do in my research group, where we use observations on the rotation of the Moon as a way to gather information about its deep interior.

Black Holes Don’t Suck!

Often portrayed as cosmic vacuum cleaners that ensnare everything that dares come close, black holes represent the ultimate end, in both science fact and science fiction. First theorized in the early 20th century, black holes have fascinated astronomers for the last 100 years. I will discuss the history of these systems, from the accidental discovery of Sagittarius A* at the centre of our Galaxy by Karl Jansky in the 1930s, to the violent accretion events occurring in X-ray binary systems and active galactic nuclei. I will show you that, contrary to popular belief, black holes don’t suck!
