Volker Schlue (University of Melbourne)06/07/2026, 09:00Plenary Talk
This talk reviews recent advances in mathematical general relativity on the stability and scattering problem for Kerr de Sitter spacetimes. It describes several results concerning the non-linear vacuum evolution of solutions to the Einstein equations with positive cosmological constant, near the rotating black hole solutions, and outlines some of the challenges for a non-linear theory of...

In this talk, I will present on behalf of the LIGO-Virgo-KAGRA collaborations the results from version 5.0 of the Gravitational-Wave Transient Catalog (GWTC-5.0). The updated catalog contains results from the network of observatories up to the second part of the fourth observing run (O4b). We find 161 new compact binary coalescence candidates with masses consistent with signals from the merger...

Prof. Kenny Chun Yu Ng (The Chinese University of Hong Kong)06/07/2026, 10:40Plenary Talk
Abstract: I will discuss the dark matter research program of the Large High Altitude Air Shower Array (LHAASO). Located at 4410 m above sea level, LHAASO comprises three complementary detectors—KM2A, WCDA, and WFCTA—making it the most sensitive very-high-energy gamma-ray survey instrument currently operating. This unique capability establishes LHAASO as an excellent tool for indirect dark...

Krzysztof Bolejko (University of Tasmania)06/07/2026, 11:15Plenary Talk
The nature of dark energy remains one of the central open problems in cosmology, commonly parameterised through the equation of state w(z). The inference of the dark energy equation of state w(z) is typically performed within the homogeneous FLRW paradigm. However, cosmic structure introduces inhomogeneities that can impact both observables and their interpretation. In this talk, I discuss how...

Fast Radio Bursts (FRBs) represent one of the most intriguing frontiers in modern astrophysics, yet their origins and physical mechanisms remain elusive. The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) project is a dedicated radio interferometer designed to address these fundamental challenges. By prioritizing an ultra-wide "fisheye" field of view, BURSTT compensates for its...

Prof. Nicole Bell (The University of Melbourne)07/07/2026, 09:35Plenary Talk
Neutrino physics is entering an era of precision measurement, offering unprecedented opportunities to probe neutrino properties. This talk will discuss three examples. First, we present a new approach to measuring the CP-violating phase in neutrino mixing. This involves an up-down flux ratio for sub-GeV atmospheric neutrinos. For the example of Hyper-Kamiokande --- the first experiment with...

Prof. David Wiltshire (University of Canterbury)07/07/2026, 10:10Plenary Talk
The timescape cosmology returns to first principles, to explain apparent cosmic acceleration in the statistical regime of general relativity. As inhomogeneities in density and expansion grow, they back react on the average cosmic expansion, which differs from conventional FLRW models. Crucially, dynamical spatial curvature arises as time-varying gradients of the kinetic energy of expansion,...

The PandaX (Particle AND Astrophysical Xenon Experiments) project is a staged xenon-based deep experiment at the China Jin-Ping Underground Laboratory. Using a dual-phase liquid xenon time projection chamber (TPC) technology, the PandaX-4T detector features a sensitive volume of about 4 tons to search for rare events, including the detection of dark matter, solar neutrinos, and neutrinoless...

KAGRA is a large cryogenic gravitational wave telescope located at the Kamioka Mine in Gifu Prefecture, Japan. KAGRA was constructed under the ground and it is operated using cryogenic mirrors that help in reducing the seismic and thermal noise. KAGRA has performed its observation runs. In this talk, we will report on the current status and the prospects of KAGRA.

Bin Wang (Shanghai Jiao Tong University / Yangzhou University)08/07/2026, 09:00Plenary Talk
Violent cosmic events, from black hole mergers to stellar collapses, often leave behind highly excited black hole remnants that inevitably relax to equilibrium. The relaxation is usually understood in linear perturbation theory and observed in gravitational wave. We disclose a distinct nonlinear regime exists before the linear ringdown. This intrinsic nonlinear regime is a long-lived...

Sabrina Einecke (University of Adelaide)08/07/2026, 09:35Plenary Talk
Cosmic rays play a crucial role in the evolution of galaxies, but their origin remains one of the biggest mysteries today. Their spectrum suggests the existence of so-called PeVatrons - astrophysical objects that accelerate particles up to at least PeV energies. However, we cannot trace them back to their accelerator, as they are deflected by interstellar magnetic fields. To hunt these extreme...

Prof. Misao Sasaki (Asia Pacific Center for Theoretical Physics)08/07/2026, 10:40Plenary Talk
Thanks to the rapid progress in observational cosmology, we have begun to understand the physics of the very early Universe, the inflationary universe. However our knowledge is still far from complete. Based on my personal perspective, I will first review what inflation is and what we currently know about it. Then I will discuss some recent topics that may improve our understanding of the...

Sebastian Bahamonde (Institute for Basic Science, Daejon)08/07/2026, 11:15Plenary Talk
Einstein’s theory describes gravity through spacetime curvature, but more general gauge-theoretic frameworks allow spacetime to carry torsion and nonmetricity as well. I will first introduce metric-affine gravity as a framework in which curvature, torsion, and nonmetricity have distinct geometric roles, and discuss the theoretical consequences of these structures, including their relation to...

Prof. Arman Shafieloo (Korea Astronomy and Space Science Institute)09/07/2026, 09:30Plenary Talk
Reconstructing the expansion history of the universe and the properties of dark energy has been a central goal in physical cosmology, with far reaching implications for our understanding of fundamental physics. In this talk, I will discuss different approaches of reconstructing dark energy properties, assess findings from the latest observational data such as DESI DR2 and discuss potential...

A strong first-order phase transition offers the intriguing possibility of explaining

the stochastic gravitational wave background at nHz frequencies. In order to avoid
cosmological constraints, such a phase transition must have occurred in a dark sector
with non-negligible couplings to the standard model -- opening promising avenues of
connecting the gravitational wave signal to the... -

Naoko Kurahashi Neilson (Drexel University, USA)09/07/2026, 11:50Plenary Talk
In the past decade, neutrino astronomy went from dream to reality with the IceCube collaboration producing observations of the very first neutrino sources in the sky and the Galactic Plane, making it the first non-electromagnetic view of our own galaxy. Fundamentally, all neutrino astronomy telescopes are particle physics detectors, and observations are only possible by teasing out an...

Seon-Hee (Sunny) Seo (Fermilab, USA)Plenary Talk
Neutrinos are still the most mysterious particles of the Standard Model. Our knowledge of leptonic CP violation and the neutrino mass ordering remains limited; the current long-baseline experiments NOvA and T2K provide only first hints. The next generation of long-baseline experiments, DUNE and Hyper-Kamiokande, is designed to resolve these questions, while the JUNO medium-baseline reactor...
