Integral Field Spectroscopy of Extended Lyman-alpha Emission from the DLA Galaxy in Q2233+131

Abstract

This paper presents observations of an extended Lyman-alpha emission nebula surrounding the galaxy responsible for the Damped Lyman-alpha Absorption (DLA) line in the spectrum of the quasar Q2233+131. With the Potsdam Multi Aperture Spectrophotometer (PMAS) we measure the properties of the extended Ly-alpha emission in an area of 3"* 5" having a total line flux of (2.8+/-0.3)*10^{-16} erg cm-2 s-1, which at redshift z=3.15 corresponds to a luminosity of (2.4 -0.2/+0.3)*10^{43} erg s-1 and a size of 23 times 38 kpc. The location of the emission is spatially coincident with the previously detected DLA galaxy, but extends significantly beyond its limb. We argue that the Ly-alpha emission is likely to be caused by an outflow from the DLA galaxy, presumably powered by star formation. In the case of negligible dust extinction, the Ly-alpha luminosity indicates a star-formation rate of 19+/-10 solar masses per year consistent with that derived from the UV continuum flux from the parent galaxy. The wind velocity indicated by the integral field spectra is of the order of several hundred km s-1. We find no indication of emission originating in a rotating disk.
