Multifrequency Astrophysics (A pillar of an interdisciplinary approach for the knowledge of the physics of our Universe)

Abstract

We will discuss the importance of the "Multifrequency Astrophysics" as a pillar of an interdisciplinary approach for the knowledge of the physics of our Universe. Indeed, as largely demonstrated in the last decades, only with the multifrequency observations of cosmic sources it is possible to get near the whole behaviour of a source and then to approach the physics governing the phenomena that originate such a behaviour. In spite of this, a multidisciplinary approach in the study of each kind of phenomenon occurring in each kind of cosmic source is even more powerful than a simple "astrophysical approach". A clear example of a multidisciplinary approach is that of "The Bridge between the Big Bang and Biology". This bridge can be described by using the competences of astrophysicists, planetary physicists, atmospheric physicists, geophysicists, volcanologists, biophysicists, biochemists, and astrobiophysicists. The unification of such competences can provide the intellectual framework that will better enable an understanding of the physics governing the formation and structure of cosmic objects, apparently uncorrelated with one another, that on the contrary constitute the steps necessary for life (e.g. Giovannelli, 2001). Indeed, a lot of the future research in astrophysics will be focussed on the discovery of exoplanets and on the possibility to detect signals for alien life somewhere in the Galaxy. An extension to a multidisciplinary approach is coming from the use of historical news reported in "old chronicle" that are a fundamental source for the newborn "archaeoastronomy". In this paper we will provide several example that marked the continuous evolution on the knowledge of the physics of our Universe.

X-Ray Binary Systems – A Cauldron of Physical Processes

“…The number of CVs is increasing very rapidly thanks to the many surveys, and in particular with the MASTER-Net Transient Detections program which detected 530 new CVs (Buckley, 2015). For reviews about CVs see the fundamental papers by Robinson (1976), Patterson (1984Patterson ( , 1994, Hack & la Dous (1993), and the books of Warner (1995) and Hellier (2001 (Giovannelli, 1985), it is important to remind the long biennial series of the Frascati Workshops about "Multifrequency Behaviour of High Energy Cosmic Sources" started in 1995, whose refereed proceedings can be found in Giovannelli & Sabau-Graziati (1996, 1999, 2002a, 2002b, 2012b, 2014b, 2015b).…”

Frascati Workshop 2017: Concluding Address

“…The supernova "Livio Gratton" produced remnant-pupils, all of them rather well known within the international astrophysical community. (Giovannelli, 2010). …”

Frontier Research in Astrophysics - A Review

“…In this paper -a short updated version of our review paper about "The impact of space experiments on our knowledge of the physics of the Universe (Giovannelli & Sabau-Graziati, 2004) (GSG2004) and subsequent updating (Giovannelli & Sabau-Graziati, 2012a, 2014a) -we will briefly discuss old and new results obtained in astrophysics that marked substantially the research in this field. Thanks to the results, chosen by us following our knowledge and feelings, we will go along different stages of the evolution of our Universe discussing briefly several examples of results that are the pillars carrying the Bridge between the Big Bang and Biology.…”
