My researchfocuses on galaxy formation at its peak phase, during the first few billion years of cosmic history (at redshift z~2). The higher density of the Universe at earlier times makes all the timescales relevant for assembly, galactic dynamics and star formation shorter, so the processes associated with galaxy formation and evolution were intensified, making this period ideal for studying galaxy evolution.
Major advances in observations and theoretical modeling allow a new understanding of the main processes that operate during this epoch. Dense streams of cold gas impact galaxies at intense rates along the “cosmic-web” of intergalactic structure, providing fuel for high star-formation rates (SFRs) and causing a state of “violent disk instability” (VDI) where several giant clumps, each containing a few percent of the disk mass and a tenth of its star formation, are continuously formed.
My research addresses some of the main open issues in this developing picture.
