Giuseppe PUGLISI
I am interested in Cosmology since there are many many open questions which people are trying to understand and interpret. We are now in the era of precision cosmology so it's going to be very exciting. My area of research is mostly based on the study of the polarization of the Cosmic Microwave Background (CMB).
I have recently started a tenure track at University of Catania, (which is also my home town!), where I joined the Astrophysics group in the Observatory and started teaching (both grad and undergrad students). Before that I worked as a staff researcher at University of Rome - Tor Vergata where I joined the cosmology group led by Nicola Vittorio and Marina Migliaccio. I spent ~5 years in my beloved California where I had the great opportunity of being a PostDoc at UC Berkeley and at the Center for Computational Cosmology, (led by Julian Borrill) and at KIPAC (Stanford University, CMB group led by Chao-Lin Kuo). Thanks to this experience, I got actively involved in several CMB experiments to date: Simons Observatory, CMB-S4 and LiteBIRD.
I graduated in Astrophysics at the International School of Advanced Studies (SISSA) in Trieste (Italy) on October, 2017 and I worked on data analysis for Cosmic Microwave Background ground based experiments under the supervision of Carlo Baccigalupi and Giulio Fabbian since October 2013 (when my PhD started)..
On December, 2016 I got a Master in High Performance Computing (MHPC) meant to improve the young scientists capability in writing massively parallel codes, installing and handling any scientific library, object oriented programming, finite element methods, iterative methods, large-data manipulation, parallel linear algebra and advanced numerical analysis.
Currently, I have several responsability roles: SO pipeline leader of Galactic and Extra-galactic science, and Simulation Production Manager for LiteBIRD. I am currently working on systematics assessments for Litebird and SO due to gain drifts and beam systematics on one hand. On the other hand, I am interested in improving the foreground modelling by identifying area of homogeneity in the spectral quantities we use to parameterize the Foreoground emission.
Challenges for the forthcoming CMB polarization experiments
One of the major challenges in the context of the Cosmic Microwave Background (CMB) radiation is to detect a polarization pattern, the so called B-modes of CMB polarization, that are thought to be directly linked to the space-time fluctuations present in the Universe at the very first instants of life. To date, several challenges have prevented to detect the B-modes partly because of the lower sensitivity of the detectors. Our own Galaxy is observed in this context as a foreground contamination. However the awareness of improving the modeling of its polarized emission has been constantly increase not only to assess the cosmological signals but also to provide new insights onto the Galactic magnetic field probed with the Galactic polarized emissions, e.g. synchrotron and thermal dust. This is particularly relevant in order to better characterize the foreground contamination for future CMB experiments (e.g. SO, LiteBIRD, CMB-S4 ), where high sensitivities are expected to be achieved
Astro-Meet
Anche quest'anno ricominciano gli appuntamenti bi-settimanali in cui parleremo delle ultime novità e scoperte astrofisiche nel mondo.
Abbiamo un canale Telegram dove puoi iscriverti -> https://t.me/+k-rqzDq1Isw0Zjc0 in cui comunicherò i vari appuntamenti e gli argomenti su cui verterà la discussione.
Gli incontri saranno di mercoledì alle 14:15 in aula F (DFA) avranno cadenza bisettimanale e non dureranno più di 40 minuti.
== BYOM@OACT ==
Bring-Your-Own-Mug at the Osservatorio Astrofisico.
Serie di incontri molto simili agli Astro-Meet che si terranno all'osservatorio, a partecipare spesso ci saranno i ricercatori dell'INAF. Portatevi la tazza il caffe' lo offro io!
Gli incontri saranno di Martedi alle 14:15 in aula Ovest (OACT) avranno cadenza bisettimanale e non dureranno più di 40 minuti, verranno sempre annunciati nel canale telegram linkato sopra.
