Dear Colleagues,

It is my pleasure to advertise the following seminar, that will be held remotely.

Title: Formation of the first supermassive black holes

Abstract:
For the origin of the first supermassive black holes in the Universe, different scenarios have been proposed, ranging from the direct collapse of massive gas clouds into one single object, run-away collisions in very dense stellar clusters, as well as accretion of initially stellar-mass black holes. In this talk I will present progress from the last several years in these different scenarios, starting with systematic tests of the direct collapse scenario and the conditions under which it is feasible. I will also discuss the possibility to have purely collison-based scenarios and their possible problems. Finally, I will present a new mixed scenario where the formation of a massive object is due to the interplay of collisions and accretions, including new results from recent numerical simulations.

Adriano Fontana (INAF, Osservatorio Astronomico di Roma)
The James Webb Space Telescope: the revolution is coming. 

The recently launched James Webb Space Telescope represents a groundbreaking revolution in our capability to study the Universe. 
With an IR sensitivity 10-1000 times and a spatial resolution 3-7 times better than its predecessors HST and Spitzer, JWST will deliver rest-frame 
optical imaging and spectroscopic data of thousands of galaxies soon after the Big Bang, of stellar populations in the core of nearby galaxies, 
of nascent planetary systems in our Galaxy.
In this talk I will briefly summarise the motivations for building this telescope and a few examples of the major discoveries that we expect from its first observations.
I will also describe the science programs in which the team in Rome (at the INAF Rome Observatory and at La Sapienza) are involved.
I will conclude by briefly mentionioning the synergies with other forthcoming space missions (e.g. Euclid) and ground-based future telescopes like ELT.

Next gravity-theory webinar:

*Speaker: *David Pere?iguez (Madrid, IFT)
*Title: *Love Numbers and Magnetic Susceptibility of Charged Black Holes
*Date:  *Wednesday, January 26th at 3pm CET
*Location: *Zoom (see below)

*Abstract:*
Four-dimensional black holes (BH) of GR do not deform under external
fields. This is a very special result of 4D, and ceases to hold in higher
dimensions. In this talk I will discuss the gravitational and magnetic
response of charged BHs in arbitrary spacetime dimensions D. First, I will
derive exact analytical expressions for the tensor Love numbers in terms of
the BH temperature. These turn out to vanish at extremality. In contrast,
vector Love numbers and magnetic susceptibilities increase significantly as
one approaches the maximally charged limit. I will provide exact analytical
expressions at extremality and solve numerically the finite-temperature and
finite-charge case, obtaining agreement with our results at zero
temperature and those previously known for the neutral limit. In D=4 all
response parameters remain zero at all temperatures. I will conclude by
discussing aspects that could be explored in future work.

The meeting will be on Zoom:
