Higher Structures, Gravity and Fields
09 Jan 2023 - 27 Jan 2023 • Mainz , Germany
Organizer:
Mainz Institute for Theoretical Physics, Johannes Gutenberg University
Abstract:
We organise a 3-week programme bringing together theoretical physicists and mathematicians working in the areas of gravity, dualities, extended geometry, field theory, higher homotopy structures, and other infinite-dimensional superalgebras. The overarching goal is to make progress in constructing “exotic” field theories, where conventional notions of spacetime break down, and thus traditional methods fail. These include exotic forms of gravity, extended (double and exceptional) geometry, string/M-theory and its dualities, and higher spin theories. The common feature of these theories is the appearance of higher symmetry algebras, generalising the notion of Lie algebras. In this programme, we will bring physicists and mathematicians together working on these “higher structures” in order to better understand the fundamental structures of physical theories and develop a bootstrap based on higher structures.

Interacting Supernovae
06 Feb 2023 - 03 Mar 2023 • Munich, Germany
Organizer:
MIAPbP - Munich Institute for Astro-, Particle and BioPhysics
Abstract:
High-cadence long-term monitoring of the transient sky suggests that most core-collapse supernovae are influenced at some level by interaction with circumstellar material. Although considered so far a feature in core-collapse supernovae, this observation has led theorists to revise the idealized view of massive star evolution and explosion, introducing a slew of time-dependent, dynamical, and multi-dimensional effects that remain today poorly understood. Bringing together experts on this multi-faceted domain of astrophysics, this MIAPP programme will allow the community 1) to investigate the various mechanisms at the origin of eruptions and explosions of massive stars, 2) to improve the techniques of radiation hydrodynamics and radiative transfer modeling of these events, 3) to integrate these advances in order to dissect the rapidly growing observational zoo of interacting supernovae, and 4) to quantify the influence of circumstellar interaction on supernova-based extragalactic distance measurements. This gathering will prepare the supernova community for the upcoming era of transient astrophysics with the Vera Rubin Observatory LSST.

781. WE-Heraeus-Seminar — Time and Clocks
27 Feb 2023 - 03 Mar 2023 • Bad Honnef, Germany
Abstract:
“Time” and “clock” are ubiquitous notions that every physicist is working with, irrespectively of whether that work is experimental or theoretical in nature. In spite of that, the theoretical meanings as well as the operational realisations of these concepts are far from obvious and certainly not unique. A whole spectrum of shifts in, and losses of, interpretations occur in the transitions between classical mechanics, quantum mechanics, special-relativistic quantum-field theory, general relativity, and, finally, quantum gravity. As a result of this, issues arise that, up to this day, are the subject of challenging and often controversial debates. Recent developments in high-precision metrology partly help to resharpen but partly also refuel these controversies. Our seminar intends to bring together scientists from different disciplines in order to foster a productive dialogue on the problematic issues in connection with “time” and “clock”. We specifically aim to characterise, in scientific terms, a common understanding of what the “problem of time” really entails. Our seminar addresses Ph.D. students as well as researchers beyond their Ph.D. degree.

AGU Chapman Conference — Advances in Understanding Alfvén Waves in the Sun and the Heliosphere
28 May 2023 - 02 Jun 2023 • Berlin, Germany
Organizer:
American Geophysical Union (AGU)
Abstract:
This conference aims to bring together scientists to review and discuss the current status of research on Alfvén waves in space plasmas, including the solar atmosphere, the solar wind, planetary magnetospheres and ionospheres, and laboratory plasmas (if relevant to space plasmas). Participants will have the opportunity to interact and exchange knowledge/ideas with scientists from the “other” communities in a collegial setting.
Topics:
Alfvén wave generation mechanisms, Alfvén wave propagation and coupling, Alfvén wave interactions with plasma and energetic particles, Alfvén wave applications in solar system plasmas

Stellar Astrophysics in the Era of Gaia, Spectroscopic, and Asteroseismic Surveys
31 Jul 2023 - 25 Aug 2023 • Munich, Germany
Organizer:
MIAPbP - Munich Institute for Astro-, Particle and BioPhysics
Abstract:
Over the past decade, the astronomical community has invested enormous efforts to exploit major ground- and space-based facilities. The advent of stellar spectroscopic surveys, such as Gaia-ESO, GALAH, and APOGEE, paved the way for the large-scale analysis of the chemical compositions of millions of stars. Time-domain photometry missions, such as CoRoT, Kepler, and TESS, allowed detailed characterization of the interior structure of stars by asteroseismic techniques. Interferometric observations with VLTI and CHARA provide new information about stellar diameters and the circumstellar environment. With Gaia, stellar luminosities and radii of millions of stars can now be derived. The upcoming facilities and surveys, such as SDSS-V, 4MOST, PLATO, LSST, and JWST will revolutionize the field with unique time-domain information, and an increase in sample size by orders of magnitude. The main challenge is to combine the large amount of high-quality observations into a general coherent picture of the fundamental parameters of stars and to position them within the context of theoretical stellar structure and stellar evolution. The MIAPP program will assess the state-of-the-art in the field and develop concepts for new strategies and models to move towards the percent-level precision and accuracy in diagnostics of stellar structure.
Topics:
This MIAPP program will focus on theoretical and observational challenges in the broad area of Stellar Astrophysics.
