42. Overview of the Euclid mission

Mario Ballardini

17/07/2026, 09:00

Invited talk

The standard cosmological model successfully describes a wide range of observations, yet the nature of dark matter and dark energy remains unknown. Euclid is ESA’s space mission designed to address these questions by mapping the extragalactic sky with high-resolution optical imaging and near-infrared photometry and spectroscopy. Its main cosmological probes, weak gravitational lensing and...

41. Gamma-Ray Bursts as probes of dark energy

Maria Dainotti (National Astronomical Observatory of Japan)

Invited talk

Testing the $Λ$CDM model requires cosmological probes spanning the wide redshift interval between Type Ia Supernovae (SNe Ia, $z\lesssim2.9$) and the Cosmic Microwave Background (CMB, $z\approx1100$). Gamma-Ray Bursts (GRBs), observed up to redshift $z=9.2$, offer the opportunity to explore this regime. Here, we investigate how many GRBs are needed to become a useful cosmological probe capable...

44. AstroGenesis: A Domain-Aware Multi-Agent Model for Data-Driven Astrophysics

Narek Sahakyan (ICRANet-Armenia)

17/07/2026, 10:10

Invited talk

Astrophysics is entering a data-rich era driven by multi-wavelength observatories and multi-messenger experiments. These facilities produce vast, heterogeneous datasets that challenge traditional analysis pipelines. General-purpose AI systems, while powerful, often lack the contextual reasoning and scientific rigor required for astrophysical interpretation. AstroGenesis is an AI-powered,...

69. A concordance picture of Tidal Disruption Event

Tsvi Piran (The Hebrew University)

17/07/2026, 11:15

Invited talk

A tidal disruption event (TDE) occurs when an ill-fated star ventures too close to a black hole. The intense gravitational forces of the black hole rip the star apart, sending roughly half of its mass hurtling into space, while the remainder falls back toward the black hole. This process produces a rich, multiwavelength observational signature—typically including an optical and ultraviolet...

51. On Synchrotron Radiation Within Non-homogeneous Astrophysical Radiator Paradigm

Mile Karlica (Astronomical Observatory Belgrade)

17/07/2026, 11:50

Invited talk

Numerous observations and numerical simulations show us that non-homogeneous magnetic fields are ubiquitous within astrophysical phenomena, be it in a regular or stochastic way. Nevertheless, models of astrophysical non-thermal radiation (namely synchrotron radiation) rarely address all the aspects of this matter. In this talk we will examine the limits of the standard synchrotron theory used...

17. Dynamical systems approach to teleparallel cosmologies

Manuel Hohmann (University of Tartu)

17/07/2026, 12:25

Invited talk

One of the most important open questions in cosmology is the so-called Hubble tension, which is an apparent disagreement between local universe measurements of the present-time Hubble parameter and measurements inferred from early-universe observations under the assumption of the $\Lambda$CDM model, which supplements general relativity (GR) with a cosmological constant $\Lambda$ and cold dark...
