Dark Matter, Dark Energy and the Cosmological Tensions, June 23-27, 2025 at Lake Como

The Schools are directed to PhD students and young Post-Docs in Physics, Astronomy and Mathematics who are interested in widening their knowledge in the fields of Physical Cosmology, Relativistic Astrophysics, General Relativity, Experimental Gravity and the Modern Quantum Theories of Gravitation. The Schools wish to introduce students to current problems, highlighting their importance and potential scientific impact. Lecturers will report on theoretical, observational and experimental aspects of the research, reviewing the latest achievements in the field.

This School

Today, cosmology and astrophysics are experiencing a dilemma: on one side, we have a very successful model, the ΛCDM model, able to adjust to almost all observations. On the other hand, such a model requires 96% of stuff about whose nature we have yet no certain knowledge: 26% of dark matter and 70% of dark energy, with only 4% left for the known matter, mostly in the form of hydrogen and helium nuclei. While dark matter seems to be necessary to explain the formation and the dynamics of galaxies and of larger structures, such as galaxy clusters and super clusters, dark energy is required to explain why our universe is in a state of accelerated expansion. The school aims at providing master’s and doctoral students and young post doctoral researchers with a perspective on the most important proposals on the nature of the dark components of the universe, not only from the theoretical point of view, but also from the experimental and observational one.

IAU Symposium 398: Compact Objects and Binaries in Dense Stellar Systems, June 16-20, 2025, Seoul

Cluster dynamics and the evolution of single and binary stars are closely intertwined, leading to different scenarios than those in the galactic field. Star clusters serve as dynamic factories for all these intriguing objects, and these topics are inherently interconnected. This symposium is intended to discuss the astrophysical origin of gravitational waves and to establish connections between theoretical and observational data concerning dynamics, populations, binaries, multiples, and compact objects (including binaries containing them) in dense star clusters. 2025 will be an excellent time to delve into the topic of star clusters and the roles of compact objects as it aligns with the release of significant results from the fourth observing run of LIGO/Virgo/KAGRA, which should provide crucial new constraints on the formation of gravitational wave sources. Additionally, numerous new discoveries of globular cluster pulsars are expected from large radio facilities such as MeerKAT, ASKAP, FAST, and others. New computer codes for dynamical simulations of dense star clusters are also emerging, and this symposium offers an excellent opportunity to discuss the latest results based on these codes.

2nd European AI for Fundamental Physics Conference (EuCAIFCon 2025), June 15-20 2025, Cagliari

The second “European AI for Fundamental Physics Conference” (EuCAIFCon) will be held in Sardinia, from 15 - 20 June 2025. This event aims to provide a platform for establishing new connections between AI activities across various branches of fundamental physics, by bringing together researchers that face similar challenges and/or use similar AI solutions. The conference will be organized “horizontally”: sessions are centered on specific AI methods and themes, while being cross-disciplinary regarding the scientific questions.

EuCAIFCon 2025 is organized by EuCAIF, and hosted by the NFN Cagliari, the University of Cagliari and the University of Sassari. EuCAIF is a new European initiative for advancing the use of Artificial Intelligence (AI) in Fundamental Physics. Members are working on particle physics, astroparticle physics, nuclear physics, gravitational wave physics, cosmology, theoretical physics as well as simulation and computational infrastructure.

The Dawn of Gravitational Wave Cosmology, April 28 – May 17 2025, Benasque

Starting at its very origin, the universe is awash with mechanisms for gravitational wave (GW) production. The upcoming launch of an unprecedented array of gravitational wave missions, capable of testing more than 20 decades in frequencies, will usher in the era of gravitational wave cosmology and open up a new window on fundamental physics. It is thus more timely than ever for the physics community to identify priorities and coordinate the efforts in the field.

It is fair to say theory has not yet fully caught up with experiments and that a theory-to-data pipeline ought to be built to maximize and amplify the discovery potential of GW probes. There is more: the sheer number and range of forthcoming probes call for a truly multi-messenger approach to cosmology.

The Benasque Program is the ideal setting to:
(i) put together experts on many different GW probes, from the CMB to large scale structure, from PTAs to laser interferometers. This will enable the community to paint a complete picture of what can be achieved in the coming years, a pursuit that will not be complete without a strong focus on (ii) the possibility of cross-correlating different probes. One key aspect of cross-correlations is indeed their ability to disentangle the primordial from the astrophysical GW signal. This is central to the success of the entire field of GW cosmology.

Benasque is the beautiful town on the Spanish Pyrenees where the ‘Pedro Pascual’ Science Center (https://www.benasque.org/) is located.

Black Holes, Neutron Stars, and Gravitational Waves @ Black Sea, June 16-20 2025, Varna

The direct detection of gravitational waves heralded a new era in gravity and astrophysics, allowing us to probe the universe in ways previously thought impossible. Electromagnetic observations have also made remarkable progress over the last decade. Thus, we live now in times where the strong-field regime of gravity and the behavior of matter at ultra-high densities can be tested with unprecedented precision, offering new insights into fundamental physics.

Black Holes, Neutron Stars, and Gravitational Waves @ Black Sea aims to highlight the significance of these discoveries, discuss the latest theoretical and observational advancements, and explore future directions in the field. For this purpose, we will bring together gravity researchers from different backgrounds. We are delighted to be hosting a broad range of invited speakers and we aim for a constructive and interactive meeting. Apart from the invited speakers, we will be able to accommodate a limited number of contributed talks. A poster session will also be organized.

The main topics of the conference are:

  • Gravitational waves from the coalescence of black holes, neutron stars, and other compact object
  • Detection and analysis of gravitational waves
  • Strong field tests of General Relativity and alternative theories of gravity
  • Accretion discs and shadows of compact objects
  • Pulsar timing
  • Fundamental physics with gravitational waves
  • Modified theories of gravity
  • Long-range gravity, dark matter, dark energy
