Scientific paper

I present results from the Galaxy Evolution Explorer (GALEX) Key Project on “Lyman break galaxy analogs” (LBA). The LBA project was designed in order to search for nearby (z<0.3) UV-luminous starburst galaxies that could serve as a training set that can be compared with starbursts at higher redshift, in particular the population of UV-selected Lyman Break Galaxies (LBGs) at z ≳ 3 (Heckman et al. 2005; Hoopes et al. 2007). This search proved highly successful and we have since shown that there exists a rare population of nearby galaxies that is most similar to LBGs in terms of stellar mass, metallicity, extinction, star formation rate, size, morphology and gas kinematics (Overzier et al. 2008, 2009ab; Basu-Zych et al. 2007, 2009).
