We compute the axion-pion scattering a π →π π , relevant for the axion thermalization rate in the early Universe, within unitarized next-to-leading-order chiral perturbation theory. The latter extends the range of validity of the chiral expansion of axion-pion scattering and thus provides a crucial ingredient for the reliable determination of the

The main objective of this work is to characterize relevant properties of the hot spots obtained in the interaction between ion beams of V23 + and a spherical pure precompressed deuterium-tritium plasmas in the field of ion fast ignition scheme. In particular, we focus our analysis on the determination of the length, average temperature and maximum

We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local Volume Exploration Survey, which contains ~520 million astronomical sources covering ~4000 deg 2 of the southern sky to a 5σ point-source depth of g = 24.3, r = 23.9, i =

Zodiacal light (ZL) is sunlight scattered by interplanetary dust particles (IDPs) at optical wavelengths. The spatial distribution of IDPs in the Solar System may hold an important key to understanding the evolution of the Solar System and material transportation within it. The number density of IDPs can be expressed as n (r ) ∼r -α , and the

Context. Near-Earth asteroids (NEAs) that may evolve into impactors deserve detailed threat assessment studies. Early physical characterization of a would-be impactor may help in optimizing impact mitigation plans. We first detected NEA 2023 DZ 2 on 27 February 2023. After that, it was found to have a minimum orbit intersection distance (MOID) with

Aims: In this work we study the large-scale structure around a sample of non-fossil systems and compare the results with earlier findings for a sample of genuine fossil systems selected using their magnitude gap. Methods: We computed the distance from each system to the closest filament and intersection as obtained from a catalogue of galaxies in
