AGWAM in 2026 is structured as an integrated six-day program with two complementary components, organised on alternating days to maximise interaction between early-career researchers (ECRs), students, and experts throughout the week. The first component is a three-day student school, designed to provide a broad and accessible introduction to GW science. It will feature pedagogical lectures by leading experts and hands-on sessions covering key aspects of GW data analysis and observational techniques, such as pulsar timing. The second component is a three-day technical workshop, focusing on current research topics and recent advances in the field. It will include invited talks, contributed presentations, and open discussions, with a strong emphasis on fostering participation by ECRs. By alternating school days and workshop days, the program ensures that students and ECRs can engage closely with experts over the full week, moving seamlessly from foundational learning to cutting-edge research discussions. The scientific program will cover a broad range of topics, including: * Pulsar Timing Arrays (PTAs) and Their Transformative Sciences * Current and future ground-based GW observatories and Their Precision Sciences * Space-based GW missions and Their Discovery-Driven Sciences * Early-Universe Probes and Their Foundational Sciences * Data Analysis, Signal Processing and Their Computational Sciences Distinguished Invited Speakers Alvin Chua (National University of Singapore) Bruce Allen (Max Planck Institute for Gravitational Physics) Chunglee Kim (Ewha Womans University) Feng-Li Lin (National Taiwan Normal University) Hyung Mok Lee (Seoul National University) Lan Nguyen Quynh (Phenikaa University) Masahide Yamaguchi (Institute for Basic Science, Korea) Myungshin Im (Seoul National University) Otto Hannuksela (The Chinese University of Hong Kong) Siyuan Chen (Shanghai Astronomical Observatory) Supakchai Ponglertsakul (Silpakorn University) Takahiro Tanaka (Kyoto University) Tjonnie Li (KU Leuven) Wang-Wei Yu (Max Planck Institute for Gravitational Physics) Yan Wang (Huazhong University of Science and Technology) Yuki Inoue (National Central University, Taiwan) Students and early-career researchers are especially encouraged to participate.

Cologne-Bonn Symposium on the habitats of massive stars across cosmic time, Cologne, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=31035 Starting: 2026-08-17 to 2026-08-21 Location: Cologne, Germany Additional Information: https://sfb1601.astro.uni-koeln.de/symposium2026/ Contact: loc-msf2026[AT]ph1.uni-koeln.de We are excited to announce a conference that will bring together the world's top researchers in the field of massive star formation and evolution, with a focus on the latest advances in simulations and observations. This meeting will provide a unique opportunity to explore the latest discoveries and advancements in our understanding of the habitats of massive stars across cosmic time. Massive stars shape the evolution of galaxies through their intense radiation, feedback and ultimate deaths, yet their habitats and impact vary widely across cosmic time. Understanding the life cycle of baryonic matter, the chemical enrichment of the Universe and the regulation of star formation requires two major steps: first, bridging the large dynamic range in scale from sub-parsec dense clumps where stars are born up to hundreds of kiloparsecs in the circumgalactic medium that is affected by their feedback, and second, comparing environments that range from quiescent, nearby spiral galaxies to turbulent, high-redshift starbusts. This symposium aims to unite experts in observations, theory, simulations, laboratory astrophysics and instrumentation to identify the key physical and chemical processes governing the formation and impact of massive stars in their diverse cosmic habitats. The main questions to be addressed will focus on how universal the massive star formation process is across these diverse environments, how efficient stellar feedback is in dispersing different media, and whether the processes and structures observed locally are universal across the Universe. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.12. Thermality in Quantum Field Theory in Curved Spacetimes, Sao Paulo, Brazil --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/04/27/thermality-in-quantum-field-… Starting: 2026-08-03 to 2026-08-07 Location: Sao Paulo, Brazil Additional Information: https://www.ictp-saifr.org/tqftcs2026/ Contact: secretary[AT]ictp-saifr.org The Fulling--Davies--Unruh effect is one of the most paradigmatic predictions of quantum field theory in curved spacetimes. It states that while an inertial observer might freeze in the Minkowski vacuum, an accelerated observer might find themselves burning up in the same quantum state. Not only does this effect challenge our usual notion of the "particle" as a central object in fundamental physics, but it also points toward the possibility of deeper connections between quantum theory, thermodynamics, and spacetime. 2026 marks the fiftieth anniversary of Unruh's seminal paper on acceleration-induced thermality. Over the last five decades, many developments have advanced the understanding of thermality in quantum field theory in curved spacetimes. It is thus with great joy that we join this August to celebrate fifty years of achievements. In a bold attempt to address fifty years of progress in five days, we will discuss topics including the Fulling--Davies--Unruh effect and related predictions, entropy and entanglement in QFT, applications of Tomita--Takesaki modular theory, experimental prospects for measuring thermality, and much more.
