Gr24 & Amaldi16

The 24th International Conference on General Relativity and Gravitation (GR24) and the 16th Edoardo Amaldi Conference on Gravitational Waves (Amaldi16) were held jointly at the Scottish Exhibition Centre in Glasgow, UK, from 14–18 July 2025 (iop.eventsair.com/gr24-amaldi16). The event attracted over 800 participants and featured around 600 talks, running daily from 09:00 to 17:30. Eighteen plenary talks and four prize lectures were given in the five morning sections (09:00–12:00).

Notable plenary presentations in quantum gravity included Gautam Satishchandran on Black Hole Decoherence of Quantum Superpositions; and Mukund Rangamani on Thermodynamics of Near-Extremal Black Holes: Quantum Gravitational Effects.​​​​​​​

The afternoons consisted of parallel sessions, with 12 sections daily (except Wednesday and Friday, which had 11). The conference spanned 21 topics, covering classical and quantum gravity; mathematical and applied relativity; gravitational-wave instrumentation and data analysis; multi-messenger astronomy; relativistic astrophysics and cosmology; and education, outreach, and community-building initiatives. Parallel Session D1: Loop Quantum Gravity and Spin Foams (held Tuesday–Friday) and organized by Bianca Dittrich, featured 12 talks on topics such as, black hole perturbations and statistical mechanics; Hamiltonian renormalization, Bell-network states; non-perturbative quantum effects; and initial states and analytical cosmological perturbations in modified loop quantum cosmology.

Other three quantum gravity sessions were: Section D2: Gravitational Aspects of String Theory; Section D3: Causal Sets, Causal Dynamical Triangulations, Non-Commutative Geometry, Asymptotic Safety, and Other Quantum Gravity Approaches; and Section D4: Quantum Fields in Curved Space-Time, Semiclassical Gravity, Quantum Gravity Phenomenology, and Analogue Models.

The conference provided a comprehensive forum for cutting-edge research, fostering collaboration across the diverse fields of gravitational physics.
