Physical Properties of Strongly Lensed, Low-mass, High-redshift Galaxies Observed with X-shooter
Abstract
One of the science drivers for the second generation VLT instrument X-shooter is the exploration of emission-line galaxies at high redshifts. By targeting gravitationally lensed galaxies, we have demonstrated that, with the full spectral coverage and high overall sensitivity at medium spectral resolution for X-shooter, we can explore the physics of galaxies at redshifts between one and four, using the same methods as employed for local galaxies. In particular, we have determined abundances via direct temperature-sensitive methods, and have shown that galaxies at high redshifts also follow a relation between the physical properties of stellar mass, abundance and star formation rate, as seen in the local Universe.
