Violette Impellizzeri

Violette Impellizzeri (born 14 August 1977) is an Italian astronomer and astrophysicist specializing in active galactic nuclei and molecular clouds surrounding supermassive black holes. She is currently a professor at Leiden University, where she conducts research on these phenomena using radio interferometry.

Biography

Impellizzeri was born in Saronno, a comune in the Province of Varese, Italy. She completed her primary and secondary education in Alcamo, Sicily, before relocating with her family to Karlsruhe, Germany, where her father worked as a teacher.

She completed her studies at the European School in Karlsruhe, where she obtained her European Baccalaureate. In 1995, she entered the University of Bristol; later, she returned to Germany to complete a master's degree in physics and earned a PhD in astrophysics at the Max Planck Institute for Radio Astronomy in Bonn.

Following her doctoral studies, Impellizzeri conducted postdoctoral research at the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, focusing on physical cosmology and megamasers as part of the Megamaser Cosmology Project.

In 2011, she began working as an astronomer at the Atacama Large Millimeter Array (ALMA) in Chile. In October 2020, she returned to Europe to serve as a program manager with Allegro (ALMA Local Expertise Group) and the European ALMA Regional Center node in the Netherlands, hosted by Leiden Observatory. She currently teaches at Leiden University.

Activity

During her doctoral studies at the Max Planck Institute, she mainly focused on active galactic nuclei on Radio Astronomy. As part of her research, she conducted a series of observations using the Effelsberg 100-m Radio Telescope to detect water masers in distant galaxies. Her discoveries were later confirmed by observations made with the Very Large Array Radio Telescope in New Mexico, operated by the National Radio Astronomy Observatory.

In 2007, while at the University of Virginia, Impellizzeri was recruited by a cosmological research initiative, the National Radio Astronomy Observatory, to contribute to the Megamaser Cosmology Project. She coordinated research efforts at the Green Bank Telescope in Virginia, integrating these with observations made using the Very Long Baseline Interferometry (VLBI) system. She continued to work with the VLBI system at the ALMA in Chile, where she was involved in testing and served as a liaison for VLBI activities.

Impellizzeri joined the Atacama Cosmology Telescope project as an NRAO astronomer, working with a radio telescope operating at an altitude of 5,000 meters. She was responsible for data integration of the Atacama Large Millimeter Array observations into the VLBI network under the title of “Friend of VLBI”.
