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.

  • 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.
  • 31 May 2017: A preprint for “A 33 GHz Survey of Local Major Mergers” (Barcos-Muñoz+) has been released. In this paper we measure the sizes of starbursts using 33 GHz radio continuum and use them to compute luminosity surface densitites for the starbursts. We find a number of sources that likely exceed the luminosity surface densities for starbursts limited by radiation pressure. The paper has been accepted for publication in the Astrophysical Journal.
    Update (12 July): The article has now been published in ApJ.
  • 12 May 2017: Two recent papers I co-authored were the subject of press releases. For Ricci+2017 NASA announced that “Merging Galaxies Have Enshrouded Black Holes”. And for Kim+2017, the Chandra X-ray observatory announced the discovery of “CXO J101527.2+625911: Astronomers Pursue Renegade Supermassive Black Hole”. The press releases are based on papers recently publshed in MNRAS and ApJ, respectively.
