Titolo: Impulsive heating in the solar corona: large scale magnetic rearrangements

Abstract:

Abstract: Multiband observations show clear evidence for large-scale magnetic interaction of coronal loops in solar active regions. These loops are transiently (~20 min) bright in hot EUV channels (Atmospheric Imaging Assembly on-board Solar Dynamics Observatory, SDO/AIA), with temperatures up to about 10 MK, intersect in the plane of the sky, and their footpoints are hot spots for a short time in transition region UV lines (Interface Region Imaging Spectrograph, IRIS). The UV spectral features can be explained as produced by non-thermal electron beams hitting the transition region and generating a heat pulse of less than 1 minute. This is consistent with periodic pulsations detected in EUV light curves along the interacting loops, produced by sloshing wave fronts driven by short heat pulses. These loop systems represent excellent laboratories for studying impulsive heating mechanisms and allow us to focus physical models for diagnostics. We show preliminary MHD modeling of interacting loops.

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.
