The Lynx arc, with a redshift of 3.357, was discovered during spectroscopic follow-up of the z ¼ 0:570 cluster RX J0848+4456 from the ROSAT Deep Cluster Survey. The arc is characterized by a very red RK color and strong, narrow emission lines. Analysis of HST WFPC2 imaging and Keck opticaland infrared spectroscopy shows that the arc is an H ii galaxy magnified by a factor of � 10 by a complex cluster environ- ment. The high intrinsic luminosity, the emission-line spectrum, the absorption… 
A Window on the Earliest Star Formation: Extreme Photoionization Conditions of a High-ionization, Low-metallicity Lensed Galaxy at z ∼ 2*
We report new observations of SL2SJ021737-051329, a lens system consisting of a bright arc at z=1.84435, magnified ~17x by a massive galaxy at z=0.65. SL2SJ0217 is a low-mass (M <10^9 M*),

3D-HST GRISM SPECTROSCOPY OF A GRAVITATIONALLY LENSED, LOW-METALLICITY STARBURST GALAXY AT z = 1.847
We present Hubble Space Telescope (HST) imaging and spectroscopy of the gravitational lens SL2SJ02176-0513, a cusp arc at z = 1.847. The UV continuum of the lensed galaxy is very blue, which is
A young star-forming galaxy at z = 3.5 with an extended Lyman α halo seen with MUSE
Spatially resolved studies of high-redshift galaxies, an essential insight into galaxy formation processes, have been mostly limited to stacking or unusually bright objects. We present here the study
