Here be Spiral DRAGNs

Thursday March 9, 2017

 Presenter:  Minnie Mao, Marie Sklodowska-Curie Fellow at University of Manchester
 Series:  Center for Astrophysics Research and Technologies Seminar Series
 Abstract:  In the local Universe, large-scale double-lobed radio sources are almost always hosted by elliptical galaxies. This is consistent with leading galaxy formation models that suggest both elliptical galaxies and extended radio sources are the result of mergers. These models do not allow for spiral galaxies to host large-scale double-lobed radio sources. However, to-date, a handful of such sources have been observed to exist in the local Universe, including the recently discovered J1649+2635. We call these sources "spiral DRAGNs". I will give a summary of the known properties of spiral DRAGNs, and discuss recent observational results focussing on VLBI.
