AGN seminar

AGN seminar

AGN seminar is a bi-weekly virtual meeting hosted by the X-ray laboratory to dicuss Active Galactic Nuclei research across all wavelengths and subfields of astrophysics. Its aim is to foster scientific discussion and collaboration among people interested in supermassive black holes. We bring together active reserachers from Goddard's Astrophysics Division and the DC metro area universities. We also welcome external speakers. You can see the past and upcoming talks below.

The seminar takes place every other Thursday at 3:00 PM ET. If you are interested in participating or giving a talk, please contact organizers, Anna Ogorzalek, Erini Lambrides, Ryan Tanner, Francesca Civano, Tim Kallman, Kelly Whalen, or Ross Silver.
