Ascona Workshop 2025: Back-reaction Effects on Cosmological Observables, Ascona, Switzerland --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29198 Starting: 2025-06-22 to 2025-06-25 Location: Ascona, Switzerland Additional Information: https://www.astro.uzh.ch/en/Information---Events/events/ASCONA2025.html Contact: rhb[AT]physics.mcgill.ca Ascona Workshop 2025: Back-reaction Effects on Cosmological Observables Place and Date: June 22 - 25 2025 at Congressi Stefano Franscini in Ascona, Switzerland Overview Observational cosmology has entered a golden age. Windows to probe the universe such as the cosmic microwave background (CMB) and large-scale galaxy surveys (LSS) have become precision science, and new windows such as 21cm redshift surveys with radio telescopes are opening up. In light of these advances in observational cosmology, the challenges on theoretical cosmology have grown rapidly. The standard first-order linear perturbation theory, which is the current main tool in the literature, has been pushed to its limits, and improved approaches are needed in interpreting precision measurements in observational cosmology. Beyond linear order in perturbations, fluctuations on any particular physical scale obtain contributions from other Fourier modes, which are independent in the linear regime. Of particular interest among these nonlinear effects to cosmological observations are so called "back-reaction effects, by which both short wavelength non-linear fluctuations affect the larger scale modes and hence the background evolution in large-scale structure of the Universe. There are also back-reaction effects of long wavelength linear modes on the modes which are currently measured in observations. The aim of this workshop is to bring together experts working on various aspects of back-reaction problems, with particular emphasis on computing the effects on measurable quantities which are based on light cone averages.

Is it fundamental or emergent? This question lies at the foundation of contemporary physics and provides a key to unlocking some of its most challenging open problems, from quantum gravity to cosmology. The quest to understand time extends beyond the realm of physics, providing a privileged standpoint to address questions in diverse fields such as philosophy, mathematics, and computer science. In this conference, we explore the nature of time from many different perspectives. This is the occasion to honor Perimeter's "Master of Time," Lee Smolin, and to celebrate his seminal scientific contributions. Lee Smolin is a founding faculty member of Perimeter Institute and a primary inspiration behind its spirit and design. This is an opportunity to journey back in time to the origins of some of the groundbreaking initiatives that Lee helped develop, and to look forward to future developments inspired by his achievements. The conference focuses on time but also on the foundations of quantum mechanics and the quest for quantum gravity, particularly Loop Quantum Gravity, of which Lee Smolin is a co-creator. In the spirit of Lee Smolin, the conference celebrates the interdisciplinary nature of the journey toward quantum gravity, with contributions from physics, mathematics, computer science, and philosophy.

Numerical models of extreme stellar explosions: bridging the gap between the central engine and the emission region, Special Session at EAS 2025, Cork, Ireland --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/02/17/numerical-models-of-extreme-… Starting: 2025-06-23 to 2025-06-27 Location: Cork, Ireland Additional Information: https://eas.unige.ch/EAS_meeting/session.jsp?id=SS31 Contact: matteo.bugli[AT]iap.fr We are glad to announce a Special Session (SS31) titled "Numerical models of extreme stellar explosions: bridging the gap between the central engine and the emission region" at the upcoming EAS 2025 Annual Meeting. The meeting will be held on June 23-27 in Cork, Ireland, with SS31's exact date to be announced soon. This special session aims at bringing together experts in the modeling of all the different phases that characterize extreme stellar explosions, from their initial onset to the emission of the electromagnetic transient. The main goal is to foster discussions and collaborations that will help the community to develop a deeper understanding of the fundamental physical processes at work during these events and trace the path to connect observed GRBs to their stellar progenitors. We will focus on three major topics related to the modeling of extreme stellar explosions: - The formation and dynamics of the central engine (i.e. extreme core-collapse supernovae, collapsar, binary neutron stars and neutron star-black hole mergers) - The relativistic jet (launch mechanism, propagation through the stellar progenitor or the merger ejecta, interaction with the surrounding medium) - The multi-wavelength electromagnetic and multi-messenger emission (including energy dissipation mechanisms and particle acceleration processes, GW, and neutrinos) If you are interested in participating, you are kindly invited to submit an abstract by March 3. We look forward to seeing you in Cork! The organizing committee of SS31 (M. Bugli, M. Bernardini, F. Daigne, M. Obergaulinger, E. O'Connor, B.

Dark Matter, Dark Energy and the Cosmological Tensions, Como, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/02/17/dark-matter-dark-energy-and-… Starting: 2025-06-23 to 2025-06-27 Location: Como, Italy Additional Information: https://dmdet.lakecomoschool.org/ Contact: roberto.peron[AT]inaf.it Dear colleague, the "Dark Matter, Dark Energy and the Cosmological Tensions" School will be held on 23-27 June 2025, in Como, Italy, at Villa del Grumello. Event Description: Today, cosmology and astrophysics are experiencing a dilemma: on one side, we have a very successful model, the LambdaCDM 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.

Living Reviews in Relativity: "Applications of machine learning in gravitational-wave research with current interferometric detectors" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/02/27/living-reviews-in-relativity… Additional Information: https://link.springer.com/journal/41114 The open-access journal Living Reviews in Relativity has published a new review article on 27 February 2025: Cuoco, E., Cavaglia', M., Heng, I.S. et al. Applications of machine learning in gravitational-wave research with current interferometric detectors. Living Rev Relativ 28, 2 (2025). https://doi.org/10.1007/s41114-024-00055-8 Abstract: This article provides an overview of the current state of machine learning in gravitational-wave research with interferometric detectors. Such applications are often still in their early days, but have reached sufficient popularity to warrant an assessment of their impact across various domains, including detector studies, noise and signal simulations, and the detection and interpretation of astrophysical signals. In detector studies, machine learning could be useful to optimize instruments like LIGO, Virgo, KAGRA, and future detectors. Algorithms could predict and help in mitigating environmental disturbances in real time, ensuring detectors operate at peak performance. Furthermore, machine-learning tools for characterizing and cleaning data after it is taken have already become crucial tools for achieving the best sensitivity of the LIGO-Virgo-KAGRA network. In data analysis, machine learning has already been applied as an alternative to traditional methods for signal detection, source localization, noise reduction, and parameter estimation. For some signal types, it can already yield improved efficiency and robustness, though in many other areas traditional methods remain dominant. As the field evolves, the role of machine learning in advancing gravitational-wave research is expected to become increasingly prominent. This report highlights recent advancements, challenges, and perspectives for the current detector generation, with a brief outlook to the next generation of gravitational-wave detectors. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2.
