We present results for 19 “Lyman-break analogs” observed with Keck/OSIRIS with an adaptive-optics-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…

Lyman Break Analogs: Constraints on the Formation of Extreme Starbursts at Low and High Redshift
Abstract Lyman Break Analogs (LBAs), characterized by high far-UV luminosities and surface brightnesses as detected by GALEX, are intensely star-forming galaxies in the low-redshift universe (z ~
VLT/X-Shooter Spectroscopy of Lyman Break Analogs: Direct-method O/H Abundances and Nitrogen Enhancements
We used Very Large Telescope/X-Shooter to target a sample of nearby analogs of Lyman break galaxies (LBGs). These Lyman break analogs are similar to the LBGs in many of their physical properties. We

We present Very Large Telescope SINFONI near-infrared (NIR) integral field spectroscopy of six z ∼ 0.2 Lyman break galaxy “analogs” (LBAs) from which we detect H i, He i, and [Fe ii] recombination
Molecular gas properties of UV-bright star-forming galaxies at low redshift
Lyman break analogues (LBAs) are a population of star-forming galaxies at low redshift (z ∼ 0.2) selected in the ultraviolet (UV). These objects present higher star formation rates and lower dust

We present results from the Intermediate Redshift OSIRIS Chemo-Kinematic Survey (IROCKS) for sixteen z ∼ 1 and one z ∼ 1.4 star-forming galaxies. All galaxies were observed with OSIRIS with the laser
On the self-regulation of intense star-formation in galaxies at z = 1−3
(abridged) We have analyzed the properties of the rest-frame optical emission lines of a sample of 53 intensely star forming galaxies at z=1.3 to 2.7 observed with SINFONI on the ESO-VLT. We find

Abstract How is gas converted into stars across cosmic time? Observations of star-forming galaxies at high redshift indicate that the conditions of the interstellar medium (ISM) were remarkably
Extreme feedback and the epoch of reionization: clues in the local universe
The source responsible for reionizing the universe at z>6 remains uncertain. While an energetically adequate population of star-forming galaxies may be in place, it is unknown whether a large enough
