Physics Department Seminar

Date: Thu. 2 Apr, 2015 4:00 pm - 5:00 pm
Duration: 1 Hour
Location: Workman Center
Minnie Mao, a post-doctoral researcher at the NRAO, will present the Physics Department seminar. Her talk is titled, "Here be Spiral DRAGNs." 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, four such sources have been observed to exist in the local Universe. We call these sources "spiral DRAGNs". In this talk, Mao will describe the current understanding of spiral DRAGNs, and discuss their role in galaxy formation. 11 a.m. in Workman 101.
