Welcome! The next tea talk is listed here. Please check the Talk Schedule page for all the talks lined-up for 2020-2021 session. Please note we would be switching between the 10 am and 4 pm time slots on Mondays to accommodate speakers from different time zones.
We are currently completely booked for the 2020-2021 academic year. If you are interested in giving a Tea Talk (especially graduate students and postdocs), please reach out to us via the form accessible under "contact us" and we will place you on a list of potential speakers for the next academic year.
New eclipsing millisecond pulsars in the Galactic globular cluster Terzan 5
Dr. Ryan Urquhart(Michigan State University)
May 24, 2021
Owing to its massive, dense core, Terzan 5 has the richest population of millisecond pulsars known among Galactic globular clusters. Using new deep VLA (2-8 GHz) radio continuum observations of Terzan 5, we have identified a selection of known millisecond pulsars (discovered via timing analysis), plus a handful of previously unknown steep-spectrum radio sources. We also investigate the X-ray properties of these new sources. The combined X-ray/radio analysis suggests the sources are binary millisecond pulsars belonging to the 'spider' classification. The likely discovery of bright binary millisecond pulsars in a well-studied cluster like Terzan\,5 highlights how deep radio continuum imaging can complement pulsar search and timing observations.
