  Clumps in high-redshift galaxies and more 

 

Abstract

Giant star-forming regions ("clumps") with sizes < 1 kpc, masses ~ 10^9 Msun and blue colors are ubiquitous features of z ~ 2 galaxies. Interestingly, their formation phase has rarely been observed and their fate is highly uncertain. Are they born in-situ due to fragmentation of gas-rich disks or are they small companion galaxies that merged with the host? Do they migrate inward and contribute to the formation of the galaxy bulge or are they rapidly disrupted by stellar feedback? Do they play a role in the structural evolution of the host galaxy?
I will discuss our latest results derived from spatially-resolved, HST/WFC3 imaging and slitless spectroscopic observations that provide some answers to these open questions. 
Furthermore, I will take the occasion to introduce myself and my work in instrumentation and outreach to those who do not know me yet
.of solid-state detectors originally developed for high energy physics is revolutionizing astrophysical measurements.
