About me

Hello!, welcome to my personal webpage. I am Miguel Vioque and since January 2024 I am working as an ESO Fellow at the European Southern Observatory in Munich, Germany.

Born in Sevilla (Spain), I did my bachelor studies in Physics at the Universidad Complutense de Madrid (Spain) and at the University of Calgary (Canada). I obtained my master in Astrophysics and Cosmology at the Universidad Autónoma de Madrid (Spain). In October 2020, I received my PhD from the University of Leeds (UK) with a thesis titled "A census of Herbig Ae/Be stars. New candidates and analysis from a Gaia perspective" in which I studied and characterized the intermediate- to high-mass star formation regime, using data from the Gaia mission and machine learning techniques. During my PhD, I had the privilege of doing an 18 month secondment at the European Space Astronomy Centre (ESAC) in Madrid and the adjacent Centro de Astrobiología.

After my PhD, I moved to Chile for 3 years with an ALMA Fellowship at the Joint ALMA Observatory, which allowed me to do over 200 observing shifts at the ALMA telescope. Currently, at ESO-Garching, I am part of the User Support Department, and I dedicate 25% of my time to providing scientific support for the X-Shooter instrument.

My research interests focus on star and planet formation, with a particular emphasis on intermediate-mass star formation and their protoplanetary disks. I study the accretion mechanisms of forming stars, and the evolution of their dust and gas disks. This is key to understand how planets form in these disks. I am also interested in the clustering and environmental properties of forming stars. My technical expertise is varied, covering different techniques and a broad wavelength range. Mainly, I have worked with Gaia astrometry, optical and IR spectroscopy and photometry, mm-wavelength interferometry, and high-contrast imaging. I find it very useful to use machine learning techniques in my research, which I often apply to Gaia data and other large-scale surveys.

Science keywords: star formation, Herbig Ae/Be stars, T Tauri stars, young stellar objects, pre-main sequence accretion, clusters and associations, Galactic structure, protoplanetary and debris disks, planet formation, variable stars, emission-line stars, Be stars.

Technical keywords: UV to mid-IR spectroscopy and photometry, astrometry, Gaia, ALMA, VLT, machine learning, statistics, big data, large-scale surveys, mm/sub-mm interferometry, high-contrast imaging.

Miscellaneous

IDEEA association

I am a member of the IDEEA association – Inclusion, Diversity, and Equity in European Astronomy. IDEEA is an open forum for discussion and activities on all topics related to ethics and inclusion in astronomy (and also outside astronomy). I encourage interested colleagues to contact me or another IDEEA member to participate in the association. Anyone is welcome to join and more information can be found here.

Historical overview of star formation and Herbig Ae/Be stars

I wrote this (very) brief overview of the history of star formation and Herbig Ae/Be stars for the introduction of my PhD thesis. Those interested in the history of science might find it worth-reading. I compiled literature information and nothing in it is original research.
