New Wolf-Rayet galaxies – IMF in starbursts
Published online by Cambridge University Press: 25 May 2016
Abstract
We report the discovery of two new Wolf-Rayet galaxies: Mrk 1039, and F8208+2816. Two broad WR bumps at 5808Å and 4650Å indicate the presence of WCE and WNL star populations in these two sources. Comparison of the observed EW(HeII λ4686) and EW(CIV λ5808) with recent models of WR populations in young starbursts provide an indication that the stellar initial mass function in some WR galaxies might not be Salpeter-like.
