Neutrinos in Cosmology and Astrophysics

6 Mar 2024, 09:00 → 8 Mar 2024, 17:00 US/Pacific

Auditorium (TRIUMF)

Neutrinos play a crucial role in cosmology and astrophysics. They may also connect to the mysteries of dark matter and the matter-antimatter asymmetry. With many exciting new observations, measurements, and calculations expected in the coming years, it is good time to investigate what we might learn and the potential implications for fundamental physics. This workshop will bring together a diverse range of theorists and experimentalists to new directions in neutrino physics and their connections with cosmology and astrophysics.

While most of the workshop will be in-person, a remote connection will be offered as well. Please note that in-person attendance will be limited by the size of the venue. If you would like to attend at TRIUMF, please register by February 16, 2024.

09:30 → 10:00 Relic neutrinos from collapsars and neutron star mergers

In highly dense matter scenarios, such as in Supernova, collapsars, and neutron star mergers, neutrinos decouple from matter much earlier and deeper than photons. Their detection in neutrino observatories would allow us to gain valuable insight into the interior, structure, and evolution of these astrophysical environments. While much can be learned from the neutrinos emitted by a single explosion, the rarity of these events combined with neutrinos' weakly interacting nature pose challenges for their detection. Relic neutrinos, emitted since the first Supernovae and mergers occurred in the universe, provide a continuous background flux that offers an additional avenue for the study of matter under strong gravity. In this talk, I shall discuss the diffuse neutrino background from collapsars and neutron star mergers, and the prospects of learning about the equation of state of nuclear matter from its possible detection.

14:00 → 15:30 TRIUMF Colloquium - Core-collapse supernovae as probes of (not only) non-standard neutrino physics

Core-collapse supernovae are one of the most complex phenomena in the Universe. Not only are they one of the production sites of the heavy elements that enable the existence of life, but their cores are also one of the densest environments we can probe, albeit indirectly. Core-collapse supernovae are also among the most spectacular and efficient neutrino factories. Detecting these neutrinos can allow us to probe physics in extreme conditions inaccessible on Earth. In this talk, I will discuss how we can prepare for the next nearby supernova neutrino detection to extract as much information as possible from the neutrino signal. I will also talk about how observing neutrinos from all the past collapses in our Universe – the diffuse supernova neutrino background - can help us better understand the supernova population and may provide hints about physics beyond the Standard Model.
