Title: Searching for the mysterious dark matter 

The dark matter problem is one of the most exciting puzzles in our understanding of the Universe. The atoms in our bodies, planets, and stars make up only about 15% of the total matter content of the Universe. The mysterious dark matter makes up the other 85%. All evidence for dark matter comes from its gravitational interaction with ordinary matter. However, the nature and distribution of dark matter in the Universe still remain unknown. A variety of experiments are currently operating around the globe and searching for the dark matter particle. To interpret the results of these experiments, we need to know how dark matter is distributed in our Galaxy. I will describe how we can use astronomical data and cosmological simulations of galaxy formation to map the dark matter content in our Galaxy, and utilize this map to unravel the particle nature of dark matter.

Bozorgnia is an assistant professor in the Department of Physics and Astronomy at York University.

Tracing the Lives, Deaths, and Explosions of Massive Stars

Presented by Sarafina Nance

RASC Calgary

Synopsis: 

Supernovae are cosmic events of gigantic power. Their explosions can shine as bright as a galaxy, a pinprick of extraordinarily bright light in the night sky. What is less well-understood, however, is which stars reach the point of explosion and how they evolve to their deaths. Interestingly, their explosions provide astronomers with key tools to uncover fundamental aspects of our Universe. While we know that the Universe is expanding at an accelerated rate due to dark energy, the rate of the expansion of the Universe is not well-constrained. Supernovae provide us with independent ways to measure this expansion and works to resolve one of the most pivotal questions in astronomy: How fast is the Universe really expanding?

Safrina's Biography:

Sarafina received her undergraduate degree from the University of Texas at Austin's College of Natural Sciences. Her honours thesis was titled: "A Theoretical Investigation of Supernovae Progenitors". There she used astroseismology to understand stars that were about to undergo a supernova. Sarafina now works as a PhD student in the Department of Astronomy at the University of California, Berkeley. She investigates supernovae and uses them as a means to study both the make-up and ultimate fate of the universe. She works with the Lawrence Berkeley National Laboratory Centre for Computational Cosmology to use supercomputers to build models of the explosions of supernovae in the final stages.

An Evening of Exoplanets

RASC Montreal

The Royal Astronomical Society of Canada (RASC) Montreal Centre invites you to join us on Tuesday, Jan 26th at 7:00 pm EST for a discussion on Exoplanet Research. In conjunction with our friends from Guelph Physics and the Institute for Research on Exoplanets (IREX), we’ll be joined by some of Canada’s top researchers probing the depths of space focusing on planets external to our solar system, or as they’re known to scientists, exoplanets. Planned topics include:

• The James Webb Space Telescope – an orbiting infrared observatory designed to complement and extend the discoveries of the Hubble Space Telescope to be launched later this year.
• The Ariel Mission – scheduled to launch in 2029, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey Mission is the first mission dedicated to measuring the chemical composition and thermal structures of hundreds of transiting exoplanets.
• The Gaia Mission – currently in space, the Gaia mission seeks to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing its composition, formation and evolution.

We will have a live Q&A where your questions about space exploration, space science, and the cosmos, in general, will be answered! Email montrealrasc@gmail.com with any questions in advance and we'll try to include them. Please join us on Facebook Live or the Guelph Physics YouTube page for this unique opportunity to join in with some of Canada’s top space scientists!

The event will take place Tuesday, January 26 @ 7 pm EST

Two Eyed Seeing: Navajo (Dine) Astronomy & NASA Moon to Mars

Native Skywatchers

Join the Native Skywatchers for an exciting session on Navajo (Dine) little known ancient astronomy! Learn how the Coyote created chaos as the Holy Beings were naming the stars. See how Navajo star knowledge is still used today, and what is the Navajo protocol for telling stories of the sky. They will focus on the skies of the Navajo winter months. Learn from Navajo traditional knowledge holders, and visit actual classrooms in the American Southwest.

Presented by: David Begay-Ph.D., Nancy Maryboy-Ph.D., Wilphina Becenti, Albert Brent Chase, Sarah Margoles, Ashley Teren M.Ed., Tom Tomas, and Annette S. Lee-Ph.D. Our lead schools are Little Singer Community School in Winslow, Arizona and Miller Middle School in Durango, Colorado. Supporting organizations are Native Skywatchers, Indigenous Education Institute, and NASA. Funded by NASA – Next Gen STEM.

This Live Virtual Show takes place Friday, January, 29th 2021 9 am PST, 10 am MST, and 11 am CST, 12 pm EST, 1 pm AST
