History of ICRANet foundation: ICRA and ICRANet

ICRA and ICRANet

In 1985, ICRA[1] (International Center for Relativistic Astrophysics) was founded by Remo Ruffini (University of Rome "La Sapienza") together with Riccardo Giacconi (Nobel Prize for Physics 2002[2]), Abdus Salam (Nobel Prize for Physics 1979[3]), Paul Boynton (University of Washington), George Coyne (former director of the Vatican observatory), Francis Everitt (Stanford University), Fang Li-Zhi (University of Science and Technology of China).

The Establishment and the Statute of ICRANet were signed on March 19, 2003 and recognized in the same year by the Republic of Armenia and the Vatican State. ICRANet has been created in 2005 by a law of the Italian Government, ratified by the Italian Parliament and signed[4] by the President of the Italian Republic Carlo Azeglio Ciampi on February 10, 2005. The Republic of Armenia, Italy, the Vatican State, ICRA, the University of Arizona and the Stanford University are the founding members.

On September 12, 2005 the Steering Committee was established and had its first meeting. Remo Ruffini and Fang Li-Zhi were appointed respectively Director and Chairman of the Steering Committee. On December 19, 2006 the Scientific Committee was established and had its first meeting in Washington DC. Riccardo Giacconi was appointed Chairman and John Mester Co-Chairman.

On September 21, 2005 the Director of ICRANet signed with the Ambassador of Brazil Dante Coelho De Lima the adhesion of the Federative Republic of Brazil to ICRANet. The entrance of Brazil, requested by the President of Brazil Luiz Ignácio Lula Da Silva has been unanimously ratified by the Brazilian Parliament. On August 12, 2011 the President of Brazil Dilma Rousseff signed the entrance of Brazil in ICRANet.[5]

Marcel Grossmann meetings

By the beginning of the twentieth century the new branch of mathematics, tensor calculus, was developed in the works of Gregorio Ricci Curbastro and Tullio Levi Civita of the University of Padua and the University of Rome "La Sapienza". Marcel Grossmann of the University of Zurich who had a deep knowledge of the Italian school of geometry and who was close to Einstein introduced to him these concepts. The collaboration between Einstein and Grossmann was essential for the development of General Relativity.

Remo Ruffini and Abdus Salam in 1975 established the Marcel Grossmann meetings (MG) on Recent Developments in Theoretical and Experimental General Relativity, Gravitation, and Relativistic Field Theories,[6] which take place every three years in different countries gathering near 1000 researchers. MG1 and MG2 were held in 1975 and in 1979 in Trieste; MG3 in 1982 in Shanghai; MG4 in 1985 in Rome; MG5 in 1988 in Perth; MG6 in 1991 in Kyoto; MG7 in 1994 at Stanford; MG8 in 1997 in Jerusalem; MG9 in 2000 in Rome; MG10 in 2003 in Rio de Janeiro; MG11 in 2006 in Berlin; MG12 in 2009 in Paris; MG13 in 2012 in Stockholm; MG14 in 2015 in Rome. Since its foundation ICRANet plays a leading role in organization of MG meetings.

The symposia cover topics in astrophysics and cosmology, such as gamma ray bursts and compact stars, high energy cosmic rays, dark energy and dark matter, general relativity, black holes, and new physics related to cosmology.

The Galileo-Xu Guangqi meetings

The Galileo-Xu Guangqi meetings[45] have been created in the name of Galileo and Xu Guangqi, the collaborator of Matteo Ricci (Ri Ma Dou), generally recognized for bringing to China the works of Euclid and Galileo and for his strong commitment to the process of modernization and scientific development of China. The 1st Galileo - Xu Guangqi Meeting[46] was held in Shanghai, China in 2009. The 2nd Galileo - Xu Guangqi meeting took place in Hanbury Botanic Gardens (Ventimiglia, Italy) and Villa Ratti (Nice, France) in 2010. The 3rd and 4th Galileo - Xu Guangqi meetings were held in Beijing, China in 2011 and 2015, respectively.

Stueckelberg Workshops on Relativistic Field Theories

These workshops represent a one-week dialogues on Relativistic Field Theories in Curved Space, which is inspired to the work of E. C. G. Stueckelberg and is named the Stueckelberg Workshops.[47] These meetings included invited lectures by Abhay Ashtekar, Thomas Thiemann, Gerard 't Hooft and Hagen Kleinert.

Other meetings

ICRANet also organized:

PhD schools

Within IRAP PhD program ICRANet is organizing PhD schools, in particular 15 schools were held in Nice and Les Houches, France, within EMJD program.[51]

ICRANet visiting program

ICRANet has developed a program[52] of visits for scientific collaboration with short and long duration.

Prominent personalities have carried out their activities at ICRA and ICRANet, among them are: Francis Everitt, Chairman of the Scientific Committee of ICRANet, Isaak Khalatnikov, Russian physicist and former director of the Landau Institute for Theoretical Physics from 1965 to 1992; Roy Kerr, New Zealand mathematician and discoverer of the "Kerr Metric"; Thibault Damour; Demetrios Christodoulou; Hagen Kleinert; Neta and John Bachall; Tsvi Piran; Charles Misner; Robert Williams; José Gabriel Funes; Fang Li-Zhi; Rashid Sunyaev.

Weekly seminars

ICRANet co-organizes a Joint Astrophysics Seminar[53] at the Department of Physics of University "La Sapienza" and ICRA in Rome. All institutions collaborating with ICRANet as well as ICRANet centers are participating in these seminars in the regime of video conference.

Brazilian Science Data Center

The main objective of the Brazilian Science Data Center[54] (BSDC) is to provide data of all international space missions existing on the wavelength of X- and gamma rays, and later on the whole electromagnetic spectrum, for all the galactic and extragalactic sources of the Universe. A special attention will be paid to the achievement and the complete respect of the levels defined by the International Virtual Observatory Alliance (IVOA). In addition to these specific objectives, BSDC will promote technical seminars, annual workshops and it will assure a plan of scientific divulgation and popularization of science with the aim of the understanding of the Universe.

The BSDC is currently being implemented at CBPF, and at the Universidade Federal do Rio Grande do Sul (UFRGS), and will be expanded to all other ICRANet centers in Brazil as well as to the other Latin-American ICRANet Centers in Argentina, Colombia and Mexico: a unique coordinated continental research network planned for Latin America.
