MUSCATEL

MUSE Cosmic Assembly Survey Targeting Extragalactic Legacy Fields

MUSCATEL is a blind Extragalactic surveys lead by the MUSE consortium. They complement the deepest Hubble observations by providing a three-dimensional view and by spectroscopically covering the entirety of the fields without the need for pre-selection. They are especially powerful when the Universe was less than a tenth of its current age at redshifts beyond 4, revealing a unprecedented density of star-forming galaxies through their Lyman-alpha emission. Some of these so-called Lyman-Alpha Emitters found with MUSE are so faint in their continuum.

Galaxies in clusters are subject to various interactions that can transform their nature. Signatures can be found not only in their stellar structure but in their stellar populations, star formation histories, chemical enrichment, and kinematics. All these characteristics can now be measured and determined using MUSE spatially resolved spectroscopic data cubes. Strong advantages are the wavelength regime covering all important emission lines at the redshift of the cluster (z=0.4) and the pointings in a region outside the cluster core that is dominated by elliptical galaxies.

Our Master student Jan Zieten performs an analysis of emission line galaxies belonging to the cluster in the AS1063 MUSCATEL parallel field, with the goal to derive quantities such as SFR, O/H abundances, velocity fields and others.
