Title: Magnetic fields in the early Universe
Speaker: Fabrizio Renzi
Institution: Dipartimento di Fisica, Sapienza
Date: Friday, 1 February 2019
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
Magnetic fields are an ubiquitous presence in our Universe but a 
comprehensive theory describing their generation and evolution is still 
missing. An intriguing possibility is that these fields are generated in 
the pre-recombination Universe and then evolve passively until the epoch 
of structure formation. A clean way to prove the presence of primordial 
magnetic fields (PMF) is to look at Cosmic Microwave Background (CMB) 
anisotropies induced by these fields. In this talk, I will review the 
current and future bounds on PMFs as coming from the observation of the 
CMB. Finally I will discuss how magnetic fields evolve in the 
post-recombination regime and their impact on structure formation

Title: On the crest of a wave: a four-decade long scientific journey in 
honor of Valeria Ferrari
Date: Friday, 22 February 2019
Time: 8:30am
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
  In her four-decade long career, Prof. Valeria Ferrari has given 
seminal contributions to the theory of General Relativity, to 
gravitational-wave phenomenology, and to the understanding of the 
physics of neutron stars and black holes. She has mentored several 
students who have achieved prestigious academic and institutional 
positions.

This meeting will gather together her long-lasting collaborators and 
former students to celebrate Prof. Ferrari's career and the multi-faced 
aspects of her research activity, which is nowadays more timely than 
ever.

Title: Neutrino Tomography of Earth
Speaker: Andrea Donini
Institution: Institut de Fisica Corpuscolar (IFIC) Univ. di Valencia
Date: Wednesday, 27 February 2019
Time: 4:00pm
Location: Aula Amaldi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
Global informations about the Earth (such as its mass and its moment of 
inertia) can be extracted  from gravitational measurements. Propagation 
of seismic waves allow us to infer properties of the  crust, the mantle 
and the outer core. The inner core, however, cannot be tested directly, 
as seismic  waves cannot cross the liquid outer  core. Neutrinos can be 
used to measure the Earth's density profile by  means of electroweak  
interactions only, thus giving an independent  and complementary  
picture of the Earth. I will show the first sensitive neutrino Earth 
tomography result to date using one year of IceCube atmospheric 
neutrinos data, and discuss the future prospects

Title: Black holes, atoms and gravitational molecules
Speaker: Vitor Cardoso
Institution: Instituto Superior Tecnico, Lisbon
Date: Thursday, 21 February 2019
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
Black holes are the simplest macroscopic objects one can conceive of,
and are often referred to as the Hydrogen atom of General Relativity.
Black holes allow us to test the
basic tenets of General Relativity, some of which have been taken for
granted without observations: are black holes really simple, do they
always form to cloak singularities?
I will describe black hole spectroscopy with gravitational-wave
detectors, and I will provide evidence that when bound, black hole
binaries should be thought of as gravitational molecules, with global
characteristic modes and geodesics.
Finally, I will discuss how black holes and black hole binaries can be
used as particle detectors.
