Star-forming galaxies at low-redshift in the SHARDS survey
A. Lumbreras-Calle, C. Muñoz-Tuñón, J. Méndez-Abreu +13
The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy surveys allow now to study these p…

We make use of SHARDS, an ultra-deep (<26.5AB) galaxy survey that provides optical photo-spectra at resolution R~50, via medium band filters (FWHM~150A). This dataset is combined w…
The nature of giant clumps in distant galaxies probed by the anatomy of the Cosmic Snake
Antonio Cava, Daniel Schaerer, Johan Richard +4
Giant stellar clumps are ubiquitous in high-redshift galaxies. They are thought to play an important role in the build-up of galactic bulges and as diagnostics of star formation fe…
