DESCRIPTION:Speaker: Prof. R. Ragazzoni\nTitle: New Eyes on the Cosmos: Te
 lescopes Now and Next\nAbstract. Astrophysical observation has moved beyo
 nd the boundaries of the electromagnetic spectrum. Today\, we probe the Un
 iverse not only through light\, but also through messengers such as neutri
 nos and gravitational waves\, gathering information both on the physical p
 roperties of individual celestial objects and on the geometries in which t
 hey evolve. What are the most powerful telescopes of today\, and what will
  define the observatories of tomorrow\, from the perspective of a leading 
 national research institution?\n \nSpeaker: M. Romaniello\nTitle: The Hub
 ble Constant and the Quest to Measure the Universe\nAbstract. The Hubble C
 onstant\, H₀\, measures the current expansion rate of the Universe. It i
 s one of the most fundamental parameters in cosmology\, setting the absolu
 te distance scale and\,hence\, the age of the Universe and the absolute va
 lues of luminosities and sizes. Ever since a non-static Universe emerged a
 s a natural\, and yet unexpected\, consequence of Einstein's equations of 
 General Relativity\, measuring what came to be known as the Hubble Constan
 t has sparked fierce scientific debate. In this talk\, I will trace this f
 ascinating history\, from the earliest attempts to map the cosmos to the c
 urrent tension between early- and late-Universe measurements of H₀. This
  discrepancy\, if not attributable to systematic errors\, may point to phy
 sics beyond the standard cosmological model — posing one of the deepest 
 challenges to our current understanding of the Universe.\n\nhttps://indico
