Title: IceCube and the Discovery of High-Energy Cosmic Neutrinos
Speaker: Prof. Francis Halzen
Institute: University of Wisconsin-Madison
Date: Wednesday, 11 October 2017
Time: 5:00pm
Location: ACCADEMIA NAZIONALE DEI LINCEI Palazzo Corsini, Via della 
Lungara 10, Rome

Francis Halzen, born in Belgium in 1944, is a US citizen. He is 
currently Hilldale and Gregory Breit Distinguished Professor at the
University of Wisconsin-Madison and Director of its Institute for 
Elementary Particle Physics. He is also the Principal Investigator for 
the
IceCube project, the world?s largest neutrino detector, and has served 
on various advisory committees, including those for the SNO (Sudbury
Neutrino Observatory, Canada), the Max Planck Institutes in Heidelberg 
and Munich, the ICRR at the University of Tokyo, the US Particle
Physics Prioritization Panel and the ApPEC particle astrophysics 
advisory panel in Europe.
In 2015, Halzen was awarded the Balzan Prize for Astroparticle Physics 
including neutrino and gamma-ray observation ?for his unparalleled
accomplishments which have led to the construction of the large IceCube 
Neutrino Observatory in the south polar ice, a facility that has opened 
up
a new window into the Universe through the study of cosmological high 
energy neutrinos?.

Title: PTOLEMY: An Underground Experiment to Search for MeV Dark Matter 
and the Cosmic Neutrino Background
Speaker: Christopher G. Tully
Institute: Princeton University
Date: Wednesday, 11 October 2017
Time: 2:00pm
Location: Aula Rasetti, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
The Universe is dynamical and has expanded by a factor of over one 
billion between the present-day and the early thermal epoch known as the 
neutrino decoupling. The production of relic neutrinos is within seconds 
of the inflation and heating processes that imprinted the seeds of 
future structure formation in the Universe. These early universe relics 
have cooled under the expansion of the Universe and are sensed 
indirectly through the action of their diminishing thermal velocities on 
large-scale structure formation. Experimental advances have opened up 
new opportunities to directly detect the CNB, an achievement which would 
profoundly confront and extend the sensitivity of precision cosmology 
data. PTOLEMY is a novel method of 2D target surfaces, fabricated from 
Graphene, that has unique directional detection capabilities for MeV 
dark matter and forms a basis for a future large-scale relic neutrino 
detector. The discussion of PTOLEMY focusses on experimental challenges, 
recent developments and the path forward to discovery sensitivity.

LECTURE (4:00pm): Gravitational Collapse
Abstract: In this lecture I will give a review of the gravitational 
collapse mechanism in
relativistic hydrodynamics assuming spherical symmetry, presenting the 
set of non linear
Einstein/fluid equations that need to be solved, focusing on perfect 
fluids. The equation of
state plays an important role to determine the outcome of the collapse. 
I will then discuss
the concept of space time foliation presenting the set of equations in 
two specific cases:
the Misner-Sharp comoving observer (cosmic time) and the 
Misner-Hernandez null
observer (observer time). The observer time foliation is particularly 
relevant for studying
black hole formation, following the complete evolution of the black 
hole exterior. I will
conclude introducing the concept of dynamical horizons for black holes 
in spherical
symmetry, generalizing the well known Schwarzschild condition R = 2M 
for the event
horizon.

SEMINAR (5:00pm): Primordial Black Hole Formation
Abstract: In the first part I will review the mechanism of 
gravitational collapse in
relativistic hydrodynamics assuming spherical symmetry, focusing on 
perfect fluids. With
the aim of studying black hole formation in different contexts, I will 
introduce the concept of
dynamical horizons, generalizing the Schwarzschild condition R = 2M for 
the event
horizon. In the second part I will present my results on primordial 
black hole formation,
using a Lagrangian relativistic hydrodynamical code to study the 
collapse of cosmological
perturbations in the early universe. They are interesting candidates 
for the dark matter
component of the Universe as well as for the seeds of supermassive 
black holes that we
observe today in the centres of galaxies.

GENERAL COLLOQUIUM OF THE PHYSICS DEPARTMENT

Title: Latest Results from AMS on the International Space Station
Speaker: Prof. Sam Ting
Institute: Massachusetts Institute of Technology (MIT)
Date: Thursday, 26 October 2017
Time: 4:30pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University


DESCRIPTION:

In six years on the Space Station, AMS has collected more than one 
hundred billion cosmic rays up to multi-TeV energies.  The latest 
results will be presented.

Samuel Chao Chung Ting Professor at MIT and CERN, received the Nobel 
Prize in 1976, with Burton Richter, for discovering the subatomic J/psi 
particle.
He is the principal investigator for the Alpha Magnetic Spectrometer, a 
large international collaboration with a leading Italian (INFN, ASI,  
Universities) participation. AMS-02 was installed on the International 
Space Station on 19 May 2011 and it is taking data since.

Title: Rattle and Shine: Compact Binary Coalescences in the 
Gravitational-Wave Astronomy Era
Speaker: Francesco Pannarale Greco
Institute: Cardiff University
Date: Tuesday, 31 October 2017
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
The Nobel Prize winning first observation of a binary black hole merger 
in September 2015 marked the birth of gravitational-wave astronomy.  
Just two years later, gravitational and electromagnetic radiation from a 
binary neutron star coalescence were observed jointly for the first 
time, marking the birth of gravitational-wave multi-messenger astronomy. 
I will describe these two revolutionizing events that are bound to 
continue to impact astronomy, astrophysics, fundamental physics, and 
cosmology for the years to come.  I will also discuss ongoing and future 
efforts in modelling, detecting and analyzing gravitational waves from 
coalescing neutron stars and black holes.
