Radio emission from AGNs
Margo Aller is studying relativistic jet outflows from gas accretion onto massive black holes in active galactic nuclei. This research uses a combination of observations from the U-M 26-meter radio telescope (UMRAO), MOJAVE (a major VLBA program dedicated to characterizing the kinematics of these sources), complementary broadband data obtained as part of a global collaboration, and theoretical modeling. Aller is interested particularly in the geometry of magnetic fields within jets, as well as their particle composition. She has also been studying the relationship between radio band flares and activity at shorter wavelengths. Aller’s work helped identify shocks as the probable origin of radio band variability, and she was part of a team that obtained the first observational evidence for the presence of an acceleration and collimation zone within the jet, confirming the predictions of jet-launching models.
