WiP Seminars Event | Prof. Raffaella Schneider | Online
The Women in Physics Student Club is very happy to host Prof. Raffaella Schneider in our second WiP Seminars event.
Registration is required, so make sure to do it here!
In the WiP Seminars you have the chance to not only learn about research carried out by internationally renowned physicists, but also participate in an informal conversation with them and ask about their career.
Raffaella Schneider is a full professor in astrophysics at the physics department of Sapienza University of Rome, with a vast experience in several observatories and universities around the world. Her work is mostly theoretical but with tight connections with observations, both in the electromagnetic and gravitational-wave bands.

Abstract:
Observations made using large ground-based and space-borne telescopes have probed cosmic history all the way from the present-day to ≈ 700 million years after the Big Bang. Earlier on lies the remaining frontier, where the initial density fluctuations mapped by the cosmic microwave background radiation grew by many orders of magnitude, paving the way to the formation of the first stars, supernovae and black holes. During this critical phase, the Universe was transformed from its initial simple state to a highly complex system through the injection of the first heavy elements from supernovae and the emission of light from the first stars and accreting black holes. It also witnessed the assembly of the first galaxies that, according to the hierarchical structure formation paradigm, represent the building blocks of larger systems, such as our own Milky Way. Excitingly, we are at the verge of a revolution of research into this field as the James Webb Space Telescope will enable an unprecedented epochal leap forward. In this talk, I will attempt to review our current understanding of the nature of the first stars and black holes, and the impact they had on the first billion year of cosmic history and on the properties of the first galaxies and super-massive black holes.
