The other side of cosmology: what we learn from first galaxies and black holes
/ Fontana, Adriano (speaker) (INAF Rome Observatory)
The young Universe - that is, the epoch when first stars, galaxies and black holes formed in less than 0.5 Gyr after the Big Bang - is one of the most actively studied sectors of astrophysics, with deep connections to fundamental physics. In my talk (targeted to non-specialists) I will present how recent observations - mostly obtained with the space telescope JWST and the ground-based sub-mm array ALMA - are revolutionising our understanding of the formation of the first galaxies and their embedded Black Holes.
The physical nature of these galaxies is challenging our models of early galaxy formation, showing that the formation of the first stars has been more efficient than previously expected.
These galaxies also appear to host Black Holes that are more numerous and massive than expected, opening the possibility that they do not descend from stellar seeds but rather from primordial black holes of different nature.
I will finally discuss how these discoveries offer a new way to provide independent constraints on some classes of non-standard cosmologies that are being proposed to address the tensions in the current Λ-CDM model.

Fresh results (and surprises) from the James Webb Space Telescope
/ Fontana, Adriano (speaker) (INAF Rome Observatory)
In less than three years since the release of the first data, the James Webb Space Telescope has revolutionised our knowledge and understanding of the Universe.
My talk will be a non-specialist review of the concept and current status of the mission, that is designed around an innovative technology combining unprecedented collecting area and IR sensitivity, and of some of the latest results, covering a wide range of topics from the exploration of our solar system, the atmosphere of exoplanets and the search for extraterrestrial life, the evolution of galaxies and black holes in the young Universe.

Signals, Noise and Signal processing in Particle Detectors
/ Riegler, Werner (speaker) (CERN)
These lectures discuss the basic processes that give rise to signals in particle detectors. The first lecture will summarize the main points from the 2019 lecture series on this topic (https://indico.cern.ch/event/843083/) and will discuss further extensions of the Ramo-Shockly theorem that are valid for the full extent of Maxwell’s equations without limitation to weak conductivity and can be e.g [...]
