Dr Sergio Martin-Alvarez


I'm a Postdoctoral Researcher at the Institute of Astronomy and the Kavli Institute for Cosmology of University of Cambridge. I investigate the formation of structure in our Universe employing massive cosmological numerical simulations. My recent research focuses on understanding the impact that physics frequently unexplored in these simulations have in the formation of galaxies. In particular, magnetic fields, stellar radiation, and cosmic rays.

I am also interested in understanding the magnetic component of our Universe, with particular interest in figuring out what is the cosmic magnetic field and whether primordial magnetic fields are important to understand our Universe.

Prior to my current role, I obtained my PhD at the University of Oxford, working with Julien Devriendt and Adrianne Slyz, studying magnetic fields in and around galaxies.

Galaxies in the Infant Universe Were Surprisingly Mature

Oct 27, 2020

Massive galaxies were already much more mature in the early universe than previously expected. This was shown by an international team of astronomers—including researchers from the Kavli Institute for Cosmology (KICC) and the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) — who studied 118 distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA).
