Title: Planck evidence for a closed Universe and a possible crisis for 
cosmology
Speaker: Alessandro Melchiorri
Institution: Sapienza, University of Rome
Date: Thursday 20 Feb 2020
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
Recent observations are confirming the standard lambda-cold dark matter 
cosmological model in a spectacular way. This is the "earworm" song 
playing in the head of cosmologists today. But is this true? In this 
talk, I will illustrate some of the tensions that are now arising 
between cosmological observations arguing that something more ricky 
could be in place.In particular, I will show how the recent Planck 
measurements show a statistically significant evidence for a closed 
universe,  possibly opening a "cosmological crisis" where disparate 
observed properties of the Universe appear to be mutually nconsistent.

Title: Probing the Universe with Gravitational Waves
Speaker: Barry C. Barish
Institution: Caltech and UC Riverside
Date: Monday 9 Mar 2020
Time: 4:00pm
Location: Aula Amaldi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
The discovery of gravitational waves, predicted by Einstein in 1916, is 
enabling both important tests of the theory of general relativity, and 
the birth of a new astronomy. Modern astronomy, using all types of 
electromagnetic radiation, is giving us an amazing understanding of the 
complexities of the universe, and how it has evolved.  Now, 
gravitational waves and neutrinos are beginning to give us the 
opportunity to pursue some of the same astrophysical phenomena in very 
different ways, as well as to observe phenomena that cannot be studied 
with electromagnetic radiation.  The detection of gravitational waves 
and the emergence and prospects for this exciting new science will be 
explored.
