The kinematics of ionized gas in Lyman-Break Analogs at z ~ 0.2

Understand

We present results for 19 "Lyman Break Analogs" (LBAs) observed with Keck/OSIRIS with an AO-assisted spatial resolution of less than 200 pc.

• We detect satellites/companions, diffuse emission and velocity shear, all with high signal-to-noise ratios.
• These galaxies present remarkably high velocity dispersion along the line of sight(- 70 km s-1), much higher than standard star-forming spirals in the low-redshift universe.
• We artificially redshift our data to z - 2.2 to allow for a direct comparison with observations of high-z LBGs and find striking similarities between both samples.
