Il Colle di Galileo <p><em>Il Colle di Galileo</em>&nbsp;is the "display window" for the initiatives promoted by the agreement "Il Colle di Galileo – Galileo's Hill" among the University of Florence, CNR, INAF and INFN.<br>It publishes articles, by invitation only, both in Italian and in English in order to describe the main activities in Physics research taking place in several Institutions in the Arcetri area. Namely: Department of Physics and Astronomy (UNIFI), Galileo Galilei Institute for Theoretical Physics (INFN and UNIFI), National Institute of Optics (CNR) and Astrophysical Observatory of Arcetri. These include scientific reports of events like international conferences and workshops and highlights on the main results obtained by the research of "Galileo's Hill" institutes.</p> en-US <p>Authors retain the copyright and grant the journal right of first publication with the work simultaneously licensed under a <strong>Creative Commons Attribution 4.0 International Public License (<a href="">CC-BY-4.0</a>)</strong>&nbsp;that allows others to share the work with an acknowledgment of the work's authorship and initial publication.</p> <p><a href="" rel="license"><img src="" alt="Creative Commons License"></a><br>This work is licensed under a <a href="" rel="license">Creative Commons Attribution 4.0 International License</a></p> (Roberto Casalbuoni) (Alessandro Pierno) Thu, 24 Sep 2020 09:33:21 +0000 OJS 60 INAF Arcetri Astrophysical Observatory at 150 <p class="p1">On 26 September 2019, the 150th anniversary of the first inauguration of the Observatory was celebrated at the Teatro del Cielo of the INAF- Arcetri Astrophysical Observatory. This article reconstructs the highlights of the event, which was attended by numerous representatives of political and scientific institutions. Following the welcome addresses of the institutional figures, the event focused on the inaugural speech given in 1869 by the Observatory’s founder and first director, Giovan Battista Donati.</p> Sofia Randich, Simone Bianchi Copyright (c) 2020 Sofia Randich, Simone Bianchi Thu, 24 Sep 2020 09:16:50 +0000 Michael Faraday and James Clerk Maxwell: The Florentine days <p>.</p> Giuseppe Pelosi, Stefano Selleri Copyright (c) 2020 Giuseppe Pelosi, Stefano Selleri Thu, 24 Sep 2020 09:17:07 +0000 XI Congresso Nazionale Oggetti Compatti – CNOC XI <p class="p1">The 11<sup>th</sup> edition of the biennial national workshop on the physics of compact objects, “CNOC XI”, was held at the Department of Physics and Astronomy of the University of Florence.<span class="Apple-converted-space">&nbsp; </span>Workshops of this series have always intended to bring together the Italian community interested in scientific topics related to the astrophysics of compact objects: neutron stars, black holes, and white dwarfs. In recent times, the detection of gravitational waves and very high energy neutrinos has motivated the addition of multi-messenger astronomy as an important, rapidly growing subfield. The final part of the workshop has traditionally been devoted to the discussion of upcoming observational facilities and brainstorming on the science which they will make possible.</p> Elena Amato, Niccolò Bucciantini, Barbara Olmi Copyright (c) 2020 Elena Amato, Niccolò Bucciantini, Barbara Olmi Thu, 24 Sep 2020 09:18:02 +0000 Planet-forming gas seen with new eyes <p class="p1">Planets form around newly born stars in protoplanetary disks. These disks are made up of gas and dust and their chemical composition will affect that of planetary atmospheres. Therefore, study of the gas in protoplanetary disks is fundamental toward an understanding of the conditions under which a habitable planet can form. This is a primary aim of the ALMA-DOT survey carried out by the researchers of the Arcetri Astrophysical Observatory.</p> Antonio Garufi Copyright (c) 2020 Antonio Garufi Thu, 24 Sep 2020 09:18:30 +0000 Impossible interview with William Thomson - Lord Kelvin <p class="p1">An impossible interview with a famous physicist, William Thompson Lord Kelvin, is presented, highlighting both his scientific contributions and his short temper.</p> Franco Bagnoli Copyright (c) 2020 Franco Bagnoli Thu, 24 Sep 2020 09:19:00 +0000
