Solar interior and solar dynamo

The study of solar acoustic modes over the last decades has allowed the interior ofour star to be reconstructed with extreme accuracy (stratification, internal rotation andcomposition), providing critical information on its evolution, composition, dynamics andactivity. The contribution from helioseismology has also been fundamental in the solution of the solar neutrino problem, providing an experimental confirmation of the Standard Solar Model. Italian astronomers have been involved in studies and observations of solar oscillations for many years, participating in the largest helioseismological experiments. The Italian helioseismology community is one of the 10 members of the "HELAS" network, the European Helio and Asteroseismology Network.

Radio evidence of a minor merger in the Shapley supercluster

Jan 17, 2022

Radio evidence of a minor merger in the Shapley supercluster A group of radio astronomers led by INAF has conducted a multi-frequency and multi-band study of the Shapley Supercluster, where the formation of large structures is ongoing at the present cosmological age. Radio astronomers have discovered a radio emission that acts as a "bridge" between a cluster of galaxies and a group of galaxies

Multiwavelength snapshot of a repeating fast radio burst

Multiwavelength snapshot of a repeating fast radio burst With a multiwavelength campaign, a group of astronomers led by the Italian National Institute for Astrophysics (INAF) studied a repeating fast radio burst (FRB). The object FRB20201124A, discovered in November 2020, reactivated in March 2021, emitting a series of radio bursts

Classifying Seyfert Galaxies with Deep Learning

Sep 28, 2021

Classifying Seyfert Galaxies with Deep Learning Scientist uses deep learning to identify low luminous Seyfert 1.9 galaxies that are usually missed by human inspection among ten thousands of spectra. These results are published in the Astrophysical Journal Supplement Series by Yen Chen Chen, in the department of physics at Sapienza University of Rome and ICRANet
