Task: GAIA-CU5 (Photometric calibration), Payload Expert, Gaia science alerts follow-up, PLATO, J-PLUS/J-PAS


Dr. Josep Manel Carrasco is a researcher involved in Gaia calibration of photometric and spectrophotometric data (CU5 group in DPAC). He studied physics at the Universitat de Barcelona and obtained his PhD in 2006 on the design and characterization of all photometric filters proposed to fly with Gaia in the first mission design. Thanks to this work, the definition of current characteristics of the Gaia spectrophotometric instrument (BP/RP) could be done.

Currently involved in the internal calibration BP/RP data, eliminating instrumental effects and determining a way to relate all instrumental observations in any condition.

In addition to contributing to the calibration data Gaia, Josep Manel also helps in assesing the status of the satellite (in the group of experts from the payload) and creating the catalog of Gaia in CU9 coordination unit.

Taking advantage of the observations of Gaia, Josep Manel contributes to ground-based observations of the Gaia science alerts using the Joan Oró telescope from the Montsec Observatory, objects with sudden light changes detected by satellite, to classify them as supernovas, microlenses, variable starts, etc.

He is also involved in PLATO mission leading a working package on simulations of Gaia catalogue for PLATO purposes.

He is a member of J-PLUS/J-PAS consortia contributing in improving the photometric calibration, derivation of the stellar parameters and studying the white dwarf content on these two surveys from Javalambre Observatory.

He is deeply involved in outreach, being one of the usual contacts of the UB astronomy department with many press, radio and television media when some news on astronomy is on the news. He has also offered many outreach conferences and prepare different material to explain Gaia and astronomy to the general public, schools, institutes, astronomical agroupations, …

He maintain a project called Miralcel (facebook, twitter, youtube, vimeo, ivoox, blog), aiming to make outreach of astronomy and sharing visual resources to better understand astronomy related news and explain space exploration.

He has been teacher for “Space-based astronomy” subject in the “Astrophysics, particle physics and cosmology” master courses, “Observational Astronomy”, “Differential equations and vectorial calculus”, “Algebra” and “Fundamentals of laboratory” subjects in Physics degree. He also teaches the Solar System, Sun, stellar evolution and exoplanets in the astronomy courses for “Universitat de l’Experiència” offered to people older than 55 years.
