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-t... 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.
