Cepheids and RR Lyrae stars have played a historic role in the development of astronomy in a general sense. At the beginning of the 20th century, the famous period-luminosity relation played a fundamental role in the discovery of galaxies and the expansion of the universe. The study of the properties of Cepheids and RR Lyrae stars, which is highly interesting, allows us to understand the evolutionary structure of these classes of variable stars. On the other hand, it contributes significantly to the theory of stellar evolution.

Gravitational lensing represents a characteristic feature of astrophysical systems in strong gravitational fields, such as the supermassive black holes recently observed by the Event Horizon Telescope. On the other hand, strong gravitational fields are also being probed by the LIGO-Virgo-KAGRA observations of gravitational waves. With the rapidly increasing number of observed gravitational waves, it is expected that a small portion of these events will be gravitationally lensed. This workshop aims to bring together members of the astrophysical community working on lensing and wave effects in strong gravitational fields and to discuss physics relevant for both the Event Horizon Telescope and LIGO-Virgo-KAGRA observations. We plan to discuss the current open problems and perspectives in the field, facilitate the transfer of techniques between the much more mature field of lensing of electromagnetic waves towards novel studies in the lensing of gravitational waves, as well as to see how wave effects beyond the standard lensing approaches could be incorporated.

The extraordinary amount of high-quality data will open new directions for cosmology in the next few years. The increasing precision of CMB and LSS data will provide answers to current tensions and will shed light on the connections between cosmology and particle physics either behind or beyond the phenomenological success of the LambdaCDM model. At the same time, new observations at high redshifts from Lyman alpha forest and JWST and the rapid progress in gravitational-wave astronomy call for accurate theoretical predictions for new cosmological observables.

In 2024 we expect new data releases from experiments such as DESI, ACT, SPT, and new results from Euclid and JWST: the timing of this workshop is therefore very exciting. The aim of this workshop will be to discuss these latest measurements, new methodologies of data analysis, and novel theoretical developments in cosmology. The workshop format foresees invited talks, contributed talks, discussion sessions and aims in bringing together theoretical and observational cosmologists from all over the world, and providing a lively environment for a fruitful exchange of ideas on the most recent results from ACT, SPT, BICEP, DESI, Euclid, JWST, PTA and perspectives for Simons Observatory, LiteBIRD, S4, Sphere-X, Rubin-LSST and other future experiments.

Fast Radio Bursts (FRBs) remain one of the most captivating mysteries in astrophysics. These millisecond bursts of radio waves from distant cosmic sources offer a unique glimpse into extreme astrophysical environments, yet their exact origins remain unknown. From neutron stars to exotic phenomena, FRBs hold the potential to reshape our understanding of high-energy processes and the universe itself. This conference brings together experts in theory, observation, and instrumentation across multi-wavelength and multi-messenger astronomy (including gravitational waves and neutrinos). With new instruments providing precise localizations of FRBs, this meeting will focus on preparing to analyze this influx of data, integrating it with upcoming multi-wavelength and multi-messenger surveys, and fostering collaboration to unlock the mysteries of FRBs.

Over the past ten years tremendous progress has been achieved in quantum field theory thanks to the realization that symmetries can be interpreted in terms of the action of topological defects on the space of operators. This gives a generalization of the notion of symmetries, explicitly realized in many instances exploiting Lagrangian field theory techniques, uncovering a rich and unexpected landscape of physical effects in condensed matter, high energy physics, and quantum gravity. This conference will bring together the major experts in the subject, and strives to be an opportunity for participants to quickly get up to speed with the most recent advances and open problems in the field.

Dark matter is a long outstanding problem in modern astrophysics and one of the biggest mysteries physicists are currently struggling to understand. Its presence throughout the Universe is inferred by its gravitational effects on normal matter. Physicists have taken different paths to approach this problem. One of the leading lines of research is to look for new matter in the form of yet unknown particles. However, a promising avenue of research is to consider modifications of General Relativity, such as the presence of higher order curvature terms which seems to provide us with an elegant geometric interpretation of the dark matter problem. This workshop has the goal of bringing together researchers, both from theory and experiment, with different views on the dark matter issue, to be presented during the talks and discussed throughout the breaks. Hopefully we may all learn from each other and foster new ideas into understanding the perplexing nature of the dynamics of the Universe and of gravity itself.

The Kepler and TESS missions, as well as ground-based telescopes, have discovered thousands of planets on short-period orbits around other stars, including many that are Earth-size and likely to be rocky. These objects have no direct counterparts in the Solar System, and the corresponding inner regions within the protoplanetary disks that spawned them are challenging to study. This conference will confront this challenge and advance our understanding of the nature, formation and evolution of Earth-sized planets in inner protoplanetary disks by bringing together diverse experts in exoplanet demographics, protoplanetary disks, models of disks and planet formation, and meteoritics to address four key questions: (1) what is the nature of close-in rocky planets and their atmospheres? (2) do they form in situ or migrate inwards after forming further out? (3) what are the governing parameters that could vary between star systems? and (4) why are there no analogous planets around the Sun? The conference will complement and energize the associated KITP Program by including a broader range of participants and highlighting recent observational results. The goals of the conference are to synthesize current knowledge of the properties of planets and inner disks, describe the state of the art in models of planet formation and evolution, catalyze interactions between different fields, and chart a path forward for advances in observations, theory, and computational modeling.

Gravity and gauge theories share a rich infrared physics whose universal features manifest themselves in the context of asymptotic symmetries and their Noether charges. They clarify the soft factorization properties of scattering amplitudes, they play a role in the phenomenology of gravitational waves, and enter in the identification of new observable effects including gravitational and color memories. From the perspective of quantum gravity, they introduce new tools to understand the structure of the Hilbert space, and bring about a novel and promising approach to investigate a holographic principle for asymptotically flat spacetimes, currently pursued along two related lines: celestial and Carrollian holography. The latter exploits the Carroll structure at null infinity while the former takes advantage of powerful toolkit of conformal field theory. The vast majority of these developments have taken place in the last ten years and gave rise to research lines currently undergoing a fast growth. The proposed workshop aims at exploiting this rich and timely topic to bring together experts from all over the world, together with young researchers and students, with the goal to provide training, share results, build common grounds and foster new collaborations.

This workshop aims at catalyzing the joint efforts of particle physicists and cosmologists towards the exploration of new physics with large cosmological datasets. The workshop is structured to encompass three thematic weeks dedicated to model building and testing fundamental physics in cosmology, developing novel theoretical tools to search for new physics in cosmological observables, and discussing the potential of next generation experiments to probe the plethora of new physics signals. A symposium with summary talks will conclude the workshop. A concurrent school is planned, with the aim of addressing the evolving landscape of this new field and helping participants catch up with recent developments and novel tools. An important feature of the workshop is a designated focus week, devoted to the initiation of a much-needed community white paper, summarizing the new and well-motivated particle physics models that can be tested in cosmology in the light of upcoming data and planned future experiments. The workshop nicely aligns with the expected data releases from DESI and Euclid.

Active galactic nuclei (AGN) are among the most dynamic and powerful sources in the universe, powered by supermassive black holes (SMBHs) through mass accretion. The accretion rate influences many AGN properties, with high accretion rates playing a key role in growing black holes and launching outflows that may shape the host galaxy's growth. The workshop will gather astronomers to summarize the field’s current status, bridging the accretion history from the early to the local Universe, and explore the mechanisms driving their growth and impact on the Universe.
