Title: Developing new galaxy formation models that will help us learn the Universe 

Abstract:
Understanding and simulating galaxy formation from first principles is a huge computational challenge because of the vast range of scales and rich array of physics involved. Upcoming experiments will map galaxies and gas across unprecedented volumes and probe further back into cosmic time than ever before. These experiments have the potential to probe fundamental physics questions such as the nature of dark matter and dark energy, and the initial conditions of the Universe. But in order to extract the full scientific potential from these data, we need to understand how luminous tracers (stars and gas) are related to the underlying matter density field, and we must develop techniques that can accurately forward model the galaxy formation process with a computational efficiency that is orders of magnitude higher than standard numerical hydro/N-body techniques. I will describe the philosophy and status of the SMAUG (Simulating Multiscale Astrophysics to Understand Galaxies) project, and how it will form a pillar in the new Simons Collaboration "Learning the Universe", which will combine new galaxy formation models, new machine learning techniques, and simulation based inference to obtain constraints on cosmology and astrophysics.

Title: New perspectives onto the Universe in the era of multi-messenger astrophysics

Abstract:
Since the revolutionary discovery of gravitational wave (GW) emission from a binary black hole merger in 2015, the exquisite GW detectors LIGO, Virgo and KAGRA 
have detected more than 90 compact object mergers. Most notably, one of these mergers corresponds to the first binary neutron star merger, dubbed GW170817. 
This event has been transformative because it was observed in both gravitational and electromagnetic radiation, thus opening up a new era in multimessenger astrophysics. 
The multi-messenger characterisation of such an event has enabled major advances into diverse fields of modern physics from gravity, high-energy and extragalactic astrophysics, 
nuclear physics, to cosmology. In this talk, I will discuss work in strong-field gravity astrophysics and how combining observations, theory and experiment is key to make progress 
in this field. I will present the opportunities and challenges that have emerged in multi-messenger astrophysics, and what the future holds in this new era.

GENERAL COLLOQUIUM OF THE PHYSICS DEPARTMENT

Title: CMB Surveys from the Ground: Recent Achievements with ACT, Future 
Prospects with the Simons Observatory
Speaker:   Adam Hincks
Institution: Dept. of Astronomy & Astrophysics and St. Michael?s 
College, University of Toronto
Date: Tuesday, 31 May 2022
Time: 4:00pm
Location: Aula Conversi, Marconi Building, Dept. of Physics, Sapienza 
University

Abstract: The standard model of cosmology continues to enjoy firm 
empirical support from observations of the cosmic microwave background 
(CMB), especially after the achievement of the Planck satellite. 
However, there is still much we are learning, and will learn, from 
higher resolution and higher sensitivity measurements of the CMB from 
the ground. Not only can cosmological parameters be refined, B-modes be 
searched for and extensions to the standard model be tested, but new 
vistas are opening up, such as probing the astrophysics of gas in 
galaxyclusters and the cosmic web, and studying the variable microwave 
sky. In this talk I will describe recent progress with the Atacama 
Cosmology Telescope (ACT) and what we can expect from the upcoming 
Simons Observatory.
