[103.02] The UV Galaxy Luminosity Function in the Local Universe from GALEX Data

T. K. Wyder (CalTech), M. A. Treyer, B. Milliard (LAM), GALEX Science Team

We present the first preliminary results from GALEX regarding the UV galaxy luminosity function in the local universe. As a part of its mission, the GALEX satellite is performing an All-Sky Survey (AIS) in two bands centered at 1550 Å (FUV) and 2200 Å (NUV), that reaches AB magnitudes of ~21 in both bands. From matching of the GALEX AIS data with catalogs from available low-redshift surveys, we create FUV and NUV magnitude-limited redshift samples. We present a preliminary calculation of the FUV and NUV luminosity functions and compare the results with previous measurements of the UV luminosity function from the FOCA experiment.

GALEX (Galaxy Evolution Explorer) is a NASA Small Explorer, launched in April 2003. We gratefully acknowledge NASA's support for construction, operation, and science analysis for the GALEX mission.
