The influence of feedback on the baryonic content of haloes in the COLIBRE simulations

Jonathan J. Davies, Joop Schaye, Filip Huško +7

The paper uses the COLIBRE cosmological simulations to study how supernova and AGN feedback affect the gas mass fraction of dark matter haloes across different masses, showing a no…

Extending the Feynman variational principle and analytical methods to lattice polarons

S. N. Klimin, J. Tempere, M. Houtput +6

We develop and compare several analytical approximations for the ground state and zero-temperature polaron dispersion in finite-width, nonparabolic conduction bands. The main focus…

Stellar Forcing of (exo)Planetary Environments

Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13

The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…

An archival search for gamma-ray bursts gravitationally lensed by galaxy clusters

Dan Ryczanowski, Benjamin P. Jones, Benjamin P. Gompertz +1

Discoveries of gamma-ray bursts (GRBs) have become commonplace in recent decades, totalling unique detections across various missions. However, there have been…

Role of anisotropic electronic friction in laser-driven hydrogen recombination on copper

Alexander Spears, Wojciech G. Stark, Reinhard J. Maurer

Ultrafast light-driven chemical dynamics at surfaces are governed by energy transfer from excited electrons to vibrational degrees of freedom. When this nonadiabatic energy transfe…

Euclid preparation. Simulated galaxy catalogues for non-standard cosmological models

Euclid Collaboration, M. -A. Breton, P. Fosalba +289

Stage-IV galaxy surveys will provide the opportunity to test cosmological models and the underlying theory of gravity with unparalleled precision. In this context, it is crucial fo…
