Gamma ray emission from embedded young massive star clusters unveiled by Fermi-LAT [PDF]

EPJ Web of Conferences
Massive star clusters (SCs) have been proposed as additional contributors to Galactic Cosmic rays (CRs), to overcome the limitations of supernova remnants (SNR) to reach the highest energy end of the Galactic CR spectrum.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 2. Probabilistic Invasion Maps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study presents a new method to assess the hazard of deposit‐derived pyroclastic density currents (PDC), a critical threat on volcanic islands and on populated slopes of active volcanoes, considering the exemplary case study of Stromboli (Italy).

Probing the faint end of simulated galaxy counts at z ≳ 3

Astronomy & Astrophysics
Context. Simulations and observations now probe comparable redshift regimes with unprecedented accuracy. This overlap allows us to test their consistency under the same observational conditions using the forward-modeling technique. Aims.

Environmental history of filament galaxies

Astronomy & Astrophysics
Galaxy properties, such as stellar mass and star formation rate, correlate with their position within the cosmic web. Although galaxy properties can be correlated with a specific environment at a certain cosmic epoch, they may have experienced different ...

The early maturity of high-redshift galaxies: Insights from sSFR, M/L, and SFHs at z  ∼  7–14

Astronomy & Astrophysics
The James Webb Space Telescope (JWST) has revealed an unexpected excess of UV-bright galaxies at z > 10, unaccounted for by extrapolations from pre-JWST observations and theoretical models.

GLADE: Gravitational Light-Bending Astrometry Dual-Satellite Experiment

Applied Sciences
Light bending is one of the classical tests of general relativity and is a crucial aspect to be taken into account for accurate assessments of photon propagation. In particular, high-precision astrometry can constrain theoretical models of gravitation in
