Title: Unveiling the physical processes that regulate Galaxy Evolution 
through SPICA observations
Speaker:   Luigi Spinoglio
Institution: INAF-IAPS
Date: Tuesday, 16 October 2018
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
A most exciting but still unknown process in modern
astrophysics is how galaxy evolution develops from the last ten billion
years. Star formation (SF) and accretion onto supermassive black holes
(BHA) play this game. Around the peak of the SF and BHA rate histories
(z=1-4), galaxies and stars develop in dusty heavily obscured
environments, preventing optical/UV observations to reveal their
nature.
As opposite, IR spectroscopy (and photometry at higher redshift) will
reveal physically galaxy evolution, allowing to measure through lines
the main physical properties (e.g., ionization field, density,
metallicity, gas velocities, etc.). The ESA-JAXA (preselected in M5)
mission SPICA will do this.

Title: Atmospheric and Astrophysical Neutrinos with IceCube
Speaker:   Thomas K. Gaisser
Institution: Univ. Delaware
Date: Tuesday, 11 October 2018
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
There are two main categories of searches for neutrinos of 
astrophysical origin, point sources and all-sky. Neutrino sources may be 
identified by a significant excess of events from the same direction 
and/or by coincidence in time and direction with an event identified 
electromagnetically or by gravitational waves. All-sky searches are made 
by looking for an excess of high-energy neutrino-induced muons from 
below the horizon and also by selecting events that start inside the 
detector.  In all approaches the main backgrounds are atmospheric 
leptons from cosmic-ray interactions in the atmosphere, but the 
backgrounds play a different role in each case.  In this talk, I will 
review recent results from IceCube while considering the effects of the 
atmospheric backgrounds in the different analyses.

Title: Gravitational lensing and black hole shadow
Speaker: Gennadi Bisnovatyi-Kogan
Institution: Space Research Institute - Russuan Academy of Science, 
Moscow
Date: Monday, 22 October 2018
Time: 3:30pm
Location: Aula Rasetti, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
An overview of the developments in problems of the effects of 
gravitational lensing is given, including plasma influence. Deflection 
of light in the presence of gravity and plasma is determined by a 
complex combination of various physical phenomena: gravity, dispersion, 
refraction. In particular, the gravitational deflection itself, in a 
homogeneous plasma without refraction, differs from the vacuum one and 
depends on the frequency of the photon. In an inhomogeneous plasma, 
chromatic refraction also takes place. We describe chromatic effects in 
strong lens systems including a shift of angular position of image and a 
change in
magnification.

Message-ID: <CAAB73sRxDmBNjcwNrg_G1cCG4srkRGkGOgpwEJNCykW1q7AG2Q@mail.gmail.com>

Vi ricordo del seminario di Luigi Spinoglio che si terra' oggi, 16 ottobre,
in aula Conversi alle ore 16.

Si potra' assistere al seminario anche in remoto collegandosi via
Google-Hangouts.
Hangouts meeting link: https://meet.google.com/uhw-mpui-jqj

SPICA  e' stata recentemente selezionata come candidata ad essere la
prossima missione spaziale ESA-M5, ed e' di grande interesse per svariate
linee di ricerca nell'Area. Quindi invito la massima partecipazione.

Uno speciale invito e' rivolto agli studenti e giovani ricercatori, perche'
SPICA puo' rappresentare il futuro della ricerca astrofisica con
spettroscopia FIR nei prossimi 15 anni.

GENERAL COLLOQUIUM OF THE PHYSICS DEPARTMENT

Title: A chemical survey of planets in our galaxy
Speaker:   Giovanna Tinetti
Institution: University College London
Date: Tuesday, 30 October 2018
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract:
Thousands of exoplanets have now been discovered with a broad range of 
masses, sizes and orbits: from rocky Earth-size planets to large gas 
giants grazing the surface of their host star. However, the essential 
nature of these exoplanets remains largely mysterious: there is no 
known, discernible pattern linking the presence, size, or orbital 
parameters of a planet to the nature of its parent star. We have little 
idea whether the chemistry of a planet is linked to its formation 
environment, or whether the type of host star drives the physics and 
chemistry of the planet?s birth, and evolution. Work in exoplanet 
spectroscopy with current instruments has thus far been very piecemeal 
and mainly focused on gaseous planets.

	The launch of the James Webb Space Telescope in 2021 will permit for 
the first time the remote exploration of smaller planets: super-Earths 
and sub-Neptunes. However, progress with the science questions spelled 
out above demands a very large, unbiased spectroscopic survey of 
exoplanets. In the next decade new dedicated space missions, such as the 
ESA's next medium-class science mission ARIEL, have been conceived to 
conduct such a survey and to explore the nature of exoplanet atmospheres 
and, through this, the key factors affecting the formation and evolution 
of planetary systems in our galaxy.

Title: Exploring the primordial Universe
Speaker:   Umberto Maio

Date: Thursday, 25 October 2018
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza

Abstract:
Primordial times host the birth of the first stars, galaxies and  
massive black holes and represent a crucial epoch for the understanding 
of currently known cosmological objects. State-of-the-art numerical 
simulations and up-to-date data will be employed to investigate the role 
of cosmic molecules and metals, early star formation, proto-galaxy 
assembly, as well as the formation path of early massive black holes. 
Results addressing the impacts of different assumptions for the  
background cosmological model and the nature of (cold vs. warm) dark 
matter will be presented to constrain the available parameter space and 
rule out non performing models.
