AstroMcGill Episode 34 – Peter Martin



Guest: Peter Martin (CITA, UToronto). His current research focuses on the dust present in our Galaxy. We discussed what this galactic dust is, how it is detected, and what we can learn from it.

Hosts: Ryan Lynch and Sebastien Guillot.

Duration: 25 minutes.


AstroMcGill Episode 33 – Robert Archibald



GuestRobert Archibald (McGill)

Robert Archibald published the first firm detection of an anti-glitch in a magnetar. An anti-glitch is a sudden decrease of the rotation period of a magnetar (a neutron star with a very large magnetic field), by opposition to the frequently-observed glitches which are sudden increase of the period (spin-up). This discevery can have important implications for the understanding of the internal structure of these extreme objects .

Duration: 18 minutes

 


AstroMcGill Episode 32 – Ryan Lynch



GuestRyan Lynch (McGill)

Ryan studies neutron stars and in particular, pulsars. He was part a collaboration who discovered a massive pulsar in a binary system, which allows to test Einstein’s theory of general relativity.

HostsRobert Archibald and Sebastien Guillot

Duration: 25 minutes

 


AstroMcGill Episode 30 – Lucy Fortson



Guest: Lucy Fortson (U. of Minnesota). While Lucy’s initial research interest were focused on high-energy astrophysics, she joined the Zooniverse collaboration (initially the GalaxyZoo project), an online citizen-science project. We discussed what the project its challenges are, as well as some of the science that resulted from it. If you are interest in joining one of the projects of Zooniverse, visit their page and select a project.

Hosts:Ryan Lynch and Sebastien Guillot.

Duration: 33 minutes.


AstroMcGill Episode 23 – Chris Thompson



Guest:  Chris Thompson (CITA, U of Toronto). We discussed his research on gamma-ray bursts and magnetars.

Hosts: James KennedyRyan Lynch and Sebastien Guillot.

Duration: 19 minutes.


AstroMcGill Episode 22 – Chelsea Sharon



Guest: Chelsea Sharon (Rutgers University). We talked about the study of star formation in very distant galaxies.

Hosts: James Kennedy and Sebastien Guillot.

Duration: 18 minutes.


AstroMcGill Episode 21 – Victoria Scowcroft



Guest: Victoria Scowcroft (Carnegie Observatory). We talked about her involvement in the Carnegie Hubble Program, a project dedicated to the measurement of the Hubble constant by calibrating the steps of the distance ladder.

Hosts: James Kennedy and Sebastien Guillot.

Duration: 17 minutes.


AstroMcGill Episode 20 – David Tsang



Guest: David Tsang (McGill). We talked about neutron star mergers as emitters of gravitational waves. These waves are ripples in the curvature of space-time.

Hosts: James Kennedy, Ryan Lynch and Sebastien Guillot.

Duration: 23 minutes.


AstroMcGill Episode 19 – Dong Lai



Guest: Dong Lai (Cornell). We discussed his research on hot Jupiters, a type of exoplanets on which tidal forces play an important role.

Hosts: James Kennedy and Sebastien Guillot.

Duration: 22 minutes.


AstroMcGill Episode 17 – Mathias Zaldarriaga



Guest: Mathias Zaldarriaga (IAS/Princeton). We discussed various topics of cosmology (the Big Bang, inflation, the Cosmic Microwave Background, etc…).

Hosts: James Kennedy, Ryan Lynch and Sebastien Guillot.

Duration: 25 minutes.
