Titolo: Leverage data science in modern astrophysics
Abstract:
The exploration of the Universe is one of main topics within the research in Physics Sciences. All incoming and on going astrophysical surveys are characterized by a huge amount of heterogeneous multi-wavelength data, which will require efficient automatic methods to be exploited in an optimal and competitive way by the italian scientific community.
Astrophysics data are then characterized by large volume, velocity and
variety, the three conditions at thebase of the Big Data paradigm. Therefore, an approach based on data mining, statistics,
machine and deep learning, in one word Astroinformatics, is required. We
will discuss a variety of such methodologies, already available and validated in several astrophysical contexts, with  the aim at proposing a pragmatic
way to approach the scientific topics of the incoming multi-messenger
Astrophysics.

Titolo: Development polishing process for bare aluminum mirrors to ARIEL space mission

Abstract: ARIEL is the 4th medium-class mission of ESA’s Cosmic Vision Programme to see and to study the exoplanets’ atmospheres in VIS/IR. The technical innovation of the project is the use of bare aluminum for the mirrors. This material is light, cheap, and available in large quantities, but difficult to polish because it is not very dense. In this seminar, I will talk about my work at Media Lario S.r.l. for the development of the aluminum polishing process, the critical issues and the results obtained.
