AMALDI RESEARCH CENTER SEMINAR

Title: All indirect evidence of the presence of Dark Matter.
Speaker: Marcello Messina
Institution: NYU at Abu Dhabi
Date: Thursday, 10 May 2019
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
In this seminar will will discuss the most compelling evidences of the 
presence of some
matter which does not emit light (Dark Matter) however showing its 
presence by means
of the gravitational force. This seminar is especially devoted to 
students and young researchers.

AMALDI RESEARCH CENTER SEMINAR

Title: Merging Black Holes of any Size and Hierarchy
Speaker: Giacomo Fragione
Institution: Hebrew Univ.of Jerusalem
Date: Wednesday, 22 May 2019
Time: 4:00 pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza
University

Abstract: The recent discovery of gravitational waves has opened new
horizons for physics. Current and upcoming missions promise to shed light
on black holes of every size, from stellar mass sizes up to supermassive
black holes which reside in galactic nuclei. The astrophysical origin of
these mergers is among the most puzzling open questions of our time. I will
show how the rich dynamics in galactic nuclei and star clusters catalyzes
black hole mergers of any size in hierarchical systems, and make prediction
on their merger rate through cosmic time. Finally, I will also discuss how
LIGO/Virgo, LISA and other instruments will be able to shed light on the
origin of black hole mergers.

Seminario di interesse anche per studenti delle LM 17 e 58 e dei dottorati
in Fisica e Astronomy, Astrophysics and Space Science.

	GENERALE)

GENERAL COLLOQUIUM OF THE PHYSICS DEPARTMENT

Title: The first image of a black hole
Speaker:   Luciano Rezzolla
Institution: Institute for Theoretical Physics, Goethe University 
Frankfurt
Date: Tuesday, 21 May 2019
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
I will briefly discuss how the first image of a black hole was obtained 
by the EHT collaboration. In particular, I will describe the theoretical 
aspects that have allowed us to model the dynamics of the plasma 
accreting onto the black hole and how such dynamics was used to generate 
synthetic black-hole images. I will also illustrate how the comparison 
between the theoretical images and the observations has allowed us to 
deduce the presence of a black hole in M87 and to extract information 
about its properties. Finally, I will describe the lessons we have 
learned about strong-field gravity and alternatives to black holes.
