Revealing the "High Energy Universe" with multi-messenger observations

Abstract

This talk will review what is today known about the "High Energy
Universe", that is the ensemble of the astrophysical objects,
environments and mechanisms that generate and store high energy
particles in the Milky Way and in the  entire universe, and outline the
main questions that remain open in the field. Answers to these questions
are searched by a broad program of "multi-messenger" observations  that
"look" at the sky with cosmic rays, gamma rays, neutrinos and
gravitational waves.

 
About the speaker:

Prof. Paolo Lipari embarked on his research journey as a high-energy
phenomenologist, earning his PhD degree from the University of Rome in
1980 with his thesis titled "Possible Experimental Studies in an e-p
Colliding Beam Machine, Using a Hadron Calorimeter in the Direction of
the Proton Beam. In 1986, Prof. Lipari transitioned to the field of
cosmic rays, joining the MACRO experiment at the underground Gran Sasso
laboratory. In 1988, he obtained a permanent researcher position in the
section of Roma I of the National Institute for Nuclear Research (INFN)
and he became research director in 2000. Throughout his distinguished career,
Prof. Lipari has authored over 350 research papers spanning areas such
as high-energy physics, gamma astronomy, cosmic rays, neutrino physics,
dark matter searches, and multi-messenger phenomena. His remarkable
achievements were recognized during the 37th International Cosmic Ray
Conference (ICRC) in Berlin, where Prof. Lipari was honored with the
O'Ceallaigh Medal. This prestigious award acknowledged his outstanding
contributions to cosmic ray physics, encompassing neutrinos, high-energy
interactions, and his ability to elucidate complex problems for
non-experts through pedagogy. Prof. Lipari is currently visiting TIFR as
an adjunct faculty member in the Department of High Energy Physics at
TIFR.
