Physics & Astronomy seminar: Pushing the Canadian Frontier in Pulsar and FRB Science
November 25 @ 3:00 pm
Dr. Emmanuel Fonseca,
McGill University & McGill Space Institute
The radio sky is filled with transient phenomena that yield wondrous mysteries and opportunities in astrophysics. Radio pulsars, rotating neutron stars that emit beamed radiation, serve as precise clocks for making high-precision measurements of many different astrophysical effects, including the eventual detection of gravitational waves at nanohertz frequencies. On the other hand, “fast radio bursts” (FRBs) represent the latest mystery in radio astronomy due their large energy output, durations of milliseconds, erratic spectral behavior and implied cosmological distances; the diverse landscape of proposed physical models shows that FRBs are truly enigmatic in their nature, and thus the subject of active debate.
The goal of my current and future research efforts is use pulsars and FRBs as cosmic tools for addressing frontier problems in gravitational and nuclear astrophysics. In this talk, I will describe my academic history and future research directions in studying pulsars and FRBs, as well recent and ongoing work in building instruments to observe these sources using premier Canadian observatories.
This talk is part of an interview for a Tier II Canada Research Chair position in multi-messenger astrophysics.
