AstroMcGill Episode 41 – Andrea Ghez

Guest: Andrea Ghez (UCLA)

Andrea visited the Physics Department to give the Anna I. McPherson Lectures 2013/2014 and it was our pleasure to record this podcast with her. We discussed her recent work on the supermassive black hole at the center of our Galaxy, and the observational techniques developed to indirectly observe it.

Hosts: Ryan Lynch and Sebastien Guillot

Duration: 25 minutes

AstroMcGill Episode 36 – Philip Muirhead

Guest: Philip Muirhead (Boston University).

He is interested in the wide variety of exoplanets orbiting other stars, especially low-mass stars. We talked about the detection of exoplanets and the results from the Kepler mission.

Host: Ryan Lynch.

Duration: 18 minutes.

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 .

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 31 – David Shoemaker

Guest: David H. Shoemaker (MIT). David is part of the advancedLaser Interferometer Gravitational Wave Observatory (LIGO), and we discussed gravitational waves and how LIGO is expected to detect these ripples in the curvature of space-time predicted by Einstein.

Hosts: Ryan LynchSean Griffin, and Dave Tsang.

Duration: 21 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 29 – Dan Stinebring

Guest: Dan Stinebring (Oberlin College).

The discussion was focused on gravitational waves and the NANOGrav collaboration.

Hosts: Ryan Lynch and Sean Griffin.

Duration: 17 minutes.

AstroMcGill Episode 28 – Aaron Parsons

Guest: Aaron Parsons  (UC, Berkeley). We talked about the PAPER experiment, which is hoping to shed light on the end of the “dark ages” of the Universe, just as the first stars and galaxies started to form.

Hosts: Ryan Lynch and Sean Griffin.

Duration: 19 minutes.

AstroMcGill Episode 27 – Maxim Lyutikov

Guest: Maxim Lyutikov (Purdue University). We discussed how and why pulsars emit radiation at radio wavelengths, and at higher energies in the gamma-ray and X-ray bands.

Hosts: Ryan Lynch and Dave Tsang.

Duration: 19 minutes.
