Octonions, standard model, and unification (online) --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26139 Starting: 2023-02-24 to 2023-12-15 Location: Online Additional Information: https://web.iucaa.in/attachments/events/OSMU2023LectureSeries.pdf Contact: tpsingh[AT]tifr.res.in OSMU23 Octonions, Standard Model, and Unification February 24 - December 15, 2023 An online lecture series presented by Archive Trust for Research in Mathematical Sciences and Philosophy (Oxford) and Inter-University Centre for Astronomy and Astrophysics (Pune) Motivation: Several physicists believe that quantum theory, as presently understood, is likely to be approximate, not exact. In particular, our understanding of space-time structure in quantum field theory might be in for an overhaul. Twistor theory, trace dynamics, and the number system known as the octonions, will possibly play an important role in this improved understanding of space-time. Octonions have also emerged significantly in recent years in the investigation of elementary particles, the standard model, and its unification with gravitation. The present lecture series presents ongoing research from eminent physicists and mathematicians working in these fields. Each session will be two hours long, with one hour for the talk, followed by an hour long question-answer session. Hosts: Tejinder P.

Gravitational Memory Effects: From Theory to Observation, London, UK --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/02/23/gravitational-memory-effects-... Starting: 2023-06-05 to 2023-06-09 Location: London, UK Additional Information: https://sites.google.com/view/gw-memory/ Contact: a.seraj[AT]qmul.ac.uk The past few years have witnessed a rapid growth of research in the low frequency sector of gravitational waves. This is triggered by various motivations: First, its observable consequences known as "memory effects" may be detected in the near future in current and planned gravitational wave detectors. Second, substantial breakthroughs in the holographic understanding of gravity in asymptotically flat spacetimes, have revealed a deep connection between memory and the underlying symmetries of quantum gravity. Third, novel methods to study gravitational scattering amplitudes have revealed detailed information about their soft limit. Accordingly, this topic lies at the interface between various fields of research, including quantum gravity, flat-space holography, gravitational wave theory, scattering amplitudes, mathematical GR and numerical relativity. The goal of this meeting is to bring together experts from different areas of research to discuss various aspects of gravitational memory effects. In particular, we will discuss memory effects in the context of 1- Perturbative and numerical formulation of gravitational waves 2- Observation in current and future GW detectors 3- Quantum gravity and holography 4- Scattering amplitudes and their classical limit 5- Mathematical GR and the late time behavior of gravitational waves More information, including the list of speakers and registration form can be found in the webpage of the workshop at: https://sites.google.com/view/gw-memory/ Organizers: Pau Figueras, David Nichols, Ali Seraj, and Juan A.

Living Reviews in Computational Astrophysics: "Neutrino transport in general relativistic neutron star merger simulations" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/02/24/living-reviews-in-computation... Additional Information: https://www.springer.com/journal/41115 The open-access journal Living Reviews in Computational Astrophysics has published a new review article on 23 February 2023: Francois Foucart. Neutrino transport in general relativistic neutron star merger simulations. Living Rev Comput Astrophys 9, 1 (2023). https://doi.org/10.1007/s41115-023-00016-y From the abstract: Numerical simulations of neutron star-neutron star and neutron star-black hole binaries play an important role in our ability to model gravitational-wave and electromagnetic signals powered by these systems. These simulations have to take into account a wide range of physical processes including general relativity, magnetohydrodynamics, and neutrino radiation transport. The latter is particularly important in order to understand the properties of the matter ejected by many mergers, the optical/infrared signals powered by nuclear reactions in the ejecta, and the contribution of that ejecta to astrophysical nucleosynthesis. However, accurate evolutions of the neutrino transport equations that include all relevant physical processes remain beyond our current reach. In this review, I will discuss the current state of neutrino modeling in general relativistic simulations of neutron star mergers and of their post-merger remnants. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
