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.
I am currently the organizer for the weekly PUC-IA galaxy evolution group.
- 20 April 2017: We recently had a paper accepted with an identification of a recoiling supermassive black hole candidate. “A Potential Recoiling Supermassive Black Hole CXO J101527.2+625911” (Kim+) will be published in The Astrophysical Journal and a preprint is available.
- 02 March 2017: Our paper on the far-infrared spectroscopy of local luminous infrared galaxies, “A Herschel Space Observatory Spectral Line Survey of Local Luminous Infrared Galaxies from 194 to 671 Microns” (Lu et al.) has been accepted for publication in the The Astrophysical Journal Supplement Series. A preprint is available.
- 08 February 2017: The GOALS Far-infrared photometry paper has been accepted for publication in The Astrophysical Journal Supplements. “The Great Observatories All-Sky LIRG Survey: Herschel Image Atlas and Aperture Photometry” (Chu et al.) is currently available in preprint form.
- 19 January 2017: “Growing supermassive black holes in the late stages of galaxy mergers are heavily obscured” (Ricci et al.) has been accepted for publication in the Monthly Notices of the Royal Astronomical Society. In this paper we use NuSTAR hard X-ray observations to show that late-stage mergers are more heavily obscured by gas and dust than early-stage mergers or isolated galaxies. A preprint is available on astro-ph.
- 10 January 2017: A preprint of “Direct evidence of hierarchical assembly at low masses from isolated dwarf galaxy groups” (Stierwalt et al.) is now available on the arXiv. In this paper we use Hα imaging taken with the Magellan Telescope to identify groups of dwarf galaxies (3–5 members), which are confirmed with spectroscopic follow-up. These rare groups may be interesting low-redshift analogies for the progenitors of isolated, more massive galaxies.
Update (23 January): This article is now published in Nature Astronomy.
