MOEDST-24 will be the 22nd annual international conference in the MODEST (Modeling and Observing DEnse STellar systems) meeting series. MODEST-24 will bring together researchers working on dense stellar systems and create a space for theorists and observers to connect. Our goal is to encourage a friendly exchange of knowledge, ideas and tools among groups working on similar topics and research questions. We look forward to hosting a collaborative and enriching experience for all participants. The scientific agenda of the conference will cover a broad range of topics including but not limited to: • Numerical approaches to modelling stellar systems and their constituents, • Observational properties of dense stellar systems in different environments, • Formation of dense stellar systems across cosmic time, • Stellar multiplicity, exotica, and transients in star clusters, • Compact objects and gravitational wave sources.

Advanced school on quantum spacetime will take place at the Faculty of Physics, University of Warsaw, from September 2 to September 6, 2024. The school will cover some of the most rapidly developing areas connecting quantum field theory with cosmology and gravitational physics: black holes, scattering amplitudes, gravitational waves, cosmological correlators, and celestial holography. The school will consist of five series of lectures, each series will consist of four lectures. The school is intended for graduate students, but advanced undergraduates and postdocs entering these research areas will also profit from pedagogical lectures and discussions.

Theoretical studies have shown that the multi-wavelength emission of the nuclei of active galaxies, stellar mass black hole and neutron star binaries is fueled by their accretion disks. The accretion process may be not stationary, and the accretion history as well as geometric structure of the infalling matter are not well understood. Importantly, the magnetic fields must play a key role in sustaining the accretion flows. While we have progressed in understanding many of these phenomena, there are recent observations and new models that drive our understanding in new directions. They are related either to the instabilities in the innermost part of the disk or to the sudden interaction of circumnuclear stars with the central black hole and the disk. Processes close to the black hole also allow testing of General Relativity in a strong field regime.

The Low Radioactivity Techniques (LRT) workshop series examines topics in low-radioactivity materials and techniques that are fundamental for quantum information science and rare-event searches, including dark matter, solar neutrinos, double-beta decay, long half-life phenomena and nuclear astrophysics. The workshop features updates from underground laboratories around the globe as well as the latest information regarding all aspects of low background detectors, techniques and assay programs in addition to recent developments in advanced machining and 3D printing using ultra-pure materials.
