Mattia Vaccari is an astrophysicist working in observational multi-wavelength galaxy formation and evolution.
In other words, he combines images from ground-based as well as satellite-borne telescopes to clarify the observed properties of galaxies and thus shed light on how they first formed and later evolved during the life of the universe.
He is currently based in Cape Town, South Africa, where he works at the University of Cape Town.
This blog is loosely meant to cover his daily research work and whatever strikes his fancy.
His Web Shack contains some more information about himself as well as his research.
