Possible Host Galaxy of GRB 050509b


Keck/DEIMOS spectrum of the possible host galaxy. The clear identification of Ca H and K absorption, G band absorption, and MgI sets the redshift at z=0.225. Note the absence of Hbeta or [OIII] emission. The spectral features suggest that this is probably an early-type galaxy. Finally, note that the wavelength solution at wavelengths less than 4500Ang is the most uncertain due to the absence of strong arc lamp lines.
