Mass Invariants in Riemannian Geometry: Geometry at Infinity, Lulea, Sweden --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=31364 Starting: 2027-01-11 to 2027-01-15 Location: Lulea, Sweden Additional Information: https://quasilocal.com/Conference2027/ Contact: stephen.mccormick[AT]ltu.se The notion of mass in Riemannian geometry has developed into a rich theory of geometric invariants for noncompact manifolds. Stemming from general relativity via the ADM mass of asymptotically flat manifolds and its positivity and rigidity properties, the subject now encompasses a broad spectrum of geometric settings, including asymptotically hyperbolic and asymptotically locally flat manifolds. Recent years have seen significant advances in the understanding of these mass-type invariants through spinorial methods and Weitzenboeck formulas, Hamiltonian and divergence identities, and analyses of asymptotic symmetries and conserved charges. Although most mass invariants are intertwined with scalar curvature, generalisations of mass invariants to nonlinear curvature invariants, such as Gauss-Bonnet-Chern and more general Lovelock-type masses, have since been developed. Progress has been made on questions of positivity and stability, including low-regularity settings, and the geometric characterisation of mass minimisers. We aim to bring together mathematicians interested in different notions of mass to share ideas and build new collaborations. The conference will be held at Lulea University of Technology in the north of Sweden, from January 11th to January 15th, 2027. Lulea is close to the arctic circle, so we hope for some beautiful winter weather and a chance to see the northern lights in the evenings.

Like the previous meetings in this series, TG2027 will feature the latest updates from the gravitational wave detectors, laboratory tests, cosmological surveys and other experiments, as well as discussions of recent theoretical advances. Testing Gravity remains a topical theme because of the unexplained nature of Dark Matter and Dark Energy and the long-standing failure to reconcile gravity with quantum physics. The Testing Gravity conference series aims to provide theorists working on extensions of General Relativity with a realistic perspective on what aspects of their theories can be tested. On the other hand, the experimentalists and observers get a chance to learn about new ideas that their experiments can test. There will be a one-day "school" on Wednesday, January 27th, featuring review lectures covering the key topics of the conference. The main conference, Jan 28-30, will include invited and contributed talks, and a poster session. The early registration and abstract submission deadline is Nov 30, 2026. To register and for further information, including special accommodation rates, please visit the conference website. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.3.

We envision this as the start of a recurring series - similar in spirit to the Texas Symposium - that will likely rotate among various institutions across China every few years. The symposium will cover all major topics in relativistic astrophysics, including (but not limited to) gravity and gravitational waves, formation of black holes of all scales, accretion processes around compact objects, explosive time-domain phenomena (e.g. supernovae, GRBs, TDEs), rotation and magnetically powered sources (e.g. pulsars, magnetars, FRBs), particle astrophysics (cosmic rays, gamma-rays and neutrinos), plasma astrophysics (including laboratory probes) and future high-energy astrophysics missions. Format: Oral talks + poster presentations (displayed throughout the conference). Oral talks will include both invited/solicited talks and contributed talks. Given the diverse topics covered by the symposium, it is likely the afternoon oral talks will be divided into 2-3 parallel sessions. There will be dedicated poster sessions. This conference is in-person only. The maximum number of participants in the conference is limited to 300. Registration Deadline: 1 November Abstract submission deadline: 10 October Please visit https://indico-tdli.sjtu.edu.cn/e/ISRA2026 to complete your registration and abstract submission.

Toward Sub-micro-arcsecond Astrometry: Scientific Opportunities and Measurement Pathways, Shangai, China --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=31436 Starting: 2026-12-07 to 2026-12-10 Location: Shanghai, China Additional Information: https://conf.koushare.com/conf/casfis-smastro2026 Contact: shangyuwen[AT]shao.ac.cn The Chinese Academy of Sciences Youth-Led Vanguard International Symposium "Toward Sub-micro-arcsecond Astrometry: Scientific Opportunities and Measurement Pathways" will bring together invited experts and young researchers to discuss the scientific opportunities, technical challenges, and future directions of astrometry beyond the micro-arcsecond frontier. Astrometry provides a direct way to address fundamental questions in astronomy and physics, from the formation of planetary systems and the evolution of stellar and compact-object systems to the structure of the Milky Way and the behavior of gravity across different spatial and temporal scales. By measuring positions, parallaxes, proper motions, orbital motions, and relativistic perturbations, astrometry offers a unique dynamical view of the Universe. The Gaia mission has demonstrated the transformative power of space optical astrometry and has established an unprecedented astrometric foundation for modern astronomy. However, many frontier science cases require accuracies beyond the reach of Gaia, including the detection and mass measurement of terrestrial exoplanets around nearby stars, compact-object systems, gravitational-wave-related astrometric signals, and subtle dynamical effects that demand precision and systematic-error control at or beyond the micro-arcsecond level. The symposium will focus on three core themes: science drivers at micro- and sub-micro-arcsecond precision, future measurement pathways involving instrument concepts, detectors, metrology, and observing strategies, and relativistic astrometric modeling with ephemeris support. A final discussion will explore a possible roadmap toward future space-borne sub-micro-arcsecond astrometry concepts and the associated next-generation technological capabilities. The goal of the symposium is to provide a small, focused, and discussion-oriented forum for invited experts to openly discuss major scientific and technological challenges, possible solutions, future directions, and preliminary ideas that may help shape the path toward sub-micro-arcsecond astrometry. The symposium will be held on December 7-10, 2026, at the Shanghai Astronomical Observatory, Chinese Academy of Sciences, 80 Nandan Road, Shanghai, China. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.8. 34th Texas Symposium on Relativistic Astrophysics in Melbourne, Australia --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=31439 Starting: 2027-12-13 to 2027-12-17 Location: Melbourne, Australia Additional Information: https://www.ozgrav.org/34th-texas-symposium/ Contact: ilya.mandel[AT]monash.edu Dear colleagues: The 34th Texas Symposium on Relativistic Astrophysics will be held in Melbourne, Australia, from 13-17 December 2027.
