A New Z=0 Metagalactic Ultraviolet Background Limit
We present new integral-field spectroscopy in the outskirts of two nearby, edge-on, late-type galaxies to search for the H alpha emission that is expected from the exposure of their hydrogen gas to the metagalactic ultraviolet ...
The HETDEX Pilot Survey. I. Survey Design, Performance, and Catalog of Emission-Line Galaxies
We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using awide-field integral field spectrograph. This work is partially motivated as a pilot survey for the upcoming Hobby-Eberly ...
