Giulio Magli (born 1964, Rome) is an Italian astrophysicist and archaeo-astronomer working primarily on the relationship between the architecture of ancient cultures and the sky.
Biography
After receiving a PhD in Mathematical Physics at the University of Milan, Magli developed his academic career at the Politecnico of Milan, where he became full professor of Mathematical Physics in 2005. Since 2009, he has taught a course on archaeoastronomy, first ever such course offered in an Italian University.
Work
In the field of relativistic astrophysics, Magli has worked on the so-called Cosmic Censorship conjecture. He was the first to find the general exact solution of the Einstein field equations for spherically symmetric spacetimes with tangential stresses and, together with R. Giambo', F. Giannoni and P. Piccione, to investigate the nature of the final state for these gravitational collapse models.{{cite journal|last1=Magli|first1=Giulio|year=1997|title=Gravitational collapse with non-vanishing tangential stresses: a generalization of the Tolman-Bondi model|journal=Classical and Quantum Gravity|volume=14|issue=7|pages=1937–1953|doi=10.1088/0264-9381/14/7/026|bibcode=1997CQGra..14.1937M |s2cid=250855110 }}
In the field of archaeoastronomy, Magli has investigated the foundations of the discipline and its relationship with "exact" sciences, insisting in particular on the possibility for Archaeoastronomy to make "predictions" - to be tested against facts - as any other scientific discipline can do. These ideas have been applied in particular to the relationship between topography, astronomy and dynastic history in the Egyptian pyramid's fields. In this context Magli proposed an inverse chronology between the two main pyramids of Giza as a consequence of the astronomical data, a theory which - thanks to Juan Belmonte of the IAC - developed in the idea, sustained today by both authors, that the project of the two was conceived together by Khufu in order to actualize his Akhet, symbolic horizon.{{cite book|author1=Belmonte, J.A.|url=https://books.google.com/books?id=COoYkSabGVAC&pg=PA316|title=In Search of Cosmic Order: Selected Essays on Egyptian Archaeoastronomy|author2=Shaltout, A.M.|date=2009|publisher=Supreme Council of Antiquities Press|isbn=9789774794834|page=316|accessdate=2015-06-25}}{{cite book|last1=Magli|first1=Giulio|title=Nexus Network Journal |chapter=Akhet Khufu: Archaeo-astronomical Hints at a Common Project of the Two Main Pyramids of Giza, Egypt|year=2009|isbn=978-3-7643-8973-4|pages=35–50|doi=10.1007/978-3-7643-8974-1_4|arxiv=0708.3632|s2cid=119206211 }}
Using archaeoastronomy arguments, Magli proposed an explanation for the site of the Abusir pyramid's field, as well as a possible location where the missing pyramid of the 6th dynasty king Userkare might have been located. Magli has also investigated the meaning of the Inca citadel of Machu Picchu, proposing that it was a pilgrimage center conceived in pair with that of the Island of the Sun on the Titicaca Lake.{{cite web|title=Machu Picchu Is Mini Re-creation of a Mythic Landscape?|url=http://news.nationalgeographic.com/news/2009/06/090615-machu-picchu_2.html|archive-url=https://web.archive.org/web/20090619083248/http://news.nationalgeographic.com/news/2009/06/090615-machu-picchu_2.html|url-status=dead|archive-date=June 19, 2009|publisher=news.nationalgeographic.com|accessdate=2015-06-25}}
