Nicola Gentile Fusillo

I am postdoc in the Astronomy and Astrophysics group at the University of Warwick warking with Pier-Emmanuel Tremblay on various aspects of white dwarf science.

Research interests

My research focuses on identification and characterization of white dwarfs.

I have dedicated large part of my work to identifying new white dwarfs. Using photometry and proper motions from large area surveys like the Sloan Digital Sky Survey (SDSS) and VST ATLAS to compile catalogues of white dwarf candidates. These catalogues have become fundamental resources in many projects spanning diverse areas of white dwarf science. In particular I have been interested in the follow-up study of metal-polluted white dwarfs and white dwarfs with debris discs. The "pollution" in the otherwise pristine H or He atmosphere of these white dwarfs is caused by accretion of planetary remnats, thus these stars provide a unique opportunity to study in detail the composition of rocky planetesimals.

I am also interested in large scale searches for variable white dwarf (e.g. pulsating white dwarf, magnetci white dwarfs) combining my catalogues with multi-epoch photometric surveys (SDSS Stripe 82, PTF, PanSTARRS).

Recently much of my research focused on white dwarf characterization by comparison of spectroscopy with models. In particular I am testing different model spectra accross all wavelengths from far UV to the near IR.

Other work

Between 2013/2014 I worked at the Isaac Newton Group (ING) as support astronomer for the Isaac Newton Telescope (INT) at Observatorio del Roque de los Muchachos in La Palma.
