Welcome! My name is George Privon. I am a FONDECYT postdoctoral fellow in the Instituto de Astrofísica at the Pontificia Universidad Católica de Chile. I am an astronomer and my research is focused on merger-driven transformation of galaxies across a wide range of mass. I use observations—from telescopes such as ALMA, the VLT, and the VLA—in concert with N-body simulations to understand the interplay between star formation, active galactic nuclei, feedback, and the interstellar medium in mergers. In particular, I study the molecular gas properties of extreme starbursts and the evolution of starburst and AGN activity as mergers progress.

In addition to my research, this website has some biographical information.

  • 10 August 2017: My latest paper “A Widespread, Clumpy Starburst in the Isolated Ongoing Dwarf Galaxy Merger dm1647+21” has been accepted for publication in the Astrophysical Journal. In this paper we present optical integral-field spectroscopy which show a distributed starburst in a merger of a pair of dwarf galaxies. We argue this suggests that dwarf galaxy mergers trigger starbursts though large-scale ISM compression rather than funneling of gas to the nuclei (as happens in massive galaxies). A preprint is available.
    Update (01 September 2017): The article is now published in ApJ.
  • 12 June 2017: We have released a preprint for “ALMA [NII] 205 micron Imaging Spectroscopy of the Interacting Galaxy System BRI 1202-0725 at Redshift 4.7” (Lu+). In this paper we use observations of emission from carbon monoxide and ionized nitogen along with previously obtained empirical correlations to estimate the dust temperature in a high-redshift galaxy pair. This paper has been accepted for publication in the Astrophysical Journal Letters.
  • 02 June 2017: The Summer 2017 issue of the University of Virginia magazine has a story on TiNy Titans and our discovery of groups of dwarf galaxies (Stierwalt+ 2017).
