A new paper led by Mallory Thorp, a recent UW graduate and Massive Stars research group member (now a grad student at the University of Victoria!), has just been accepted for publication in ApJ! Using Gemini-South observations obtained as part of the Fast Turnaround program, we mapped metallicity and young stellar population age in the unusual host galaxy of GRB 020903, which consists of four components that may be interacting. Like the (handful of) other GRB hosts where such detailed mapping is possible, we found that the GRB occurred in the youngest and most metal-poor region of the host.
