Supernova Neutrinos in the Multimessenger Era

Description

The IoP Astroparticle Physics (APP) group, in cooperation with the High Energy Particle Physics (HEPP) group, will hold a one-day event on multi-messenger observations of the next galactic supernova.

Preparations for observing this once-in-a-lifetime event are ongoing across many fields: Work on an updated Supernova Early Warning System (SNEWS 2.0) and next-generation neutrino detectors like DUNE and HK is progressing rapidly. At the same time, upgrades to gravitational wave detectors mean the upcoming observing run O4 will be sensitive to supernovae across most of the Milky Way. In the electromagnetic spectrum, the Vera C. Rubin Observatory will open a new era of transient astronomy, while several smaller telescopes optimised for multi-messenger follow-up are starting observations.
The goal of this workshop is to get neutrino people, EM people and gravitational wave people in the same room and we hope it might lead to future collaboration between different UK partners.

The workshop will take place on 7 April and will be held as a hybrid meeting with both in-person and virtual attendance possible. The in-person element will be hosted at King’s College London’s Bush House (South East) building at The Strand, London, WC2R 1AE. Although the event is free, registration is required due to space limitations for both in-person and online participation. Remote connection details will be provided later when registering with the Online Attendee Types.

Limited travel funding will be available for students and early career researchers. Please contact the conference organisers for more information.

        Supernova Forecast, Echoes of Supermassive Black Holes and Axion Star Explosions with Dark Matter Experiments

        Future dark matter experiments offer unprecedented opportunities for neutrino astronomy. I will discuss how coherent neutrino scattering in large direct dark matter experiments can lead to insights into the forecast of supernovae as well as the origin of supermassive black holes. If time permits, I will also highlight connections between supernovae and axion star explosions.

        Follow-up with the New Robotic Telescope

        The New Robotic Telescope (NRT), the next-generation Liverpool Telescope (LT), will have a 4-metre, 18-segment mirror, and will be located on the summit of Roque de los Muchachos in La Palma, Canary Islands. Designing and developing the world’s largest robotic telescope, with a slew speed of approximately 10 degrees/second, poses challenges that have resulted in innovative design concepts, particularly in the context of the scheduling algorithms used for optimal science efficiency. In this talk I will briefly present the latest updates for the NRT project as we approach critical design review and focus, in particular, on the science case of rapid follow-up of a Galactic supernova. This will also be discussed in the context of the new observing model, which is being adapted from the existing LT model, and the possibility of offering a combined observing facility with NRT and LT operating together.

        VHE Gamma Rays from Supernovae and CTA’s Transients Programme

        The bulk of the cosmic ray protons up to around 3 x 10^15 eV come from our Galaxy, with supernova shocks being the prime candidates for the acceleration sites. However, there is no evidence for the acceleration of particles in SNRs to the required energy from gamma-ray observations. It may be that the most energetic particles are accelerated in the early stages of Type II supernovae, resulting in prompt gamma-ray emission. I will review attempts to detect prompt gamma-rays from supernovae and consider the prospects for the Cherenkov Telescope Array (CTA).

        Gravitational Waves and Supernovae

        Core-collapse supernovae have long been considered a desirable target for gravitational-wave astronomy. Gravitational waves would provide a direct probe of motion in the inner core and potentially help to unveil the explosion mechanism. I will present the current plans for operations of the LIGO, Virgo, and KAGRA gravitational-wave observatories over the coming years, including projections for their sensitivity to gravitational waves from core-collapse supernovae, and plans for the near-real-time analysis of the data and the release of public alerts.
