CHEX-MATE: the intracluster medium entropy distribution in the gravity-dominated regime
G. Riva, G. W. Pratt, M. Rossetti +26
We characterise the entropy profiles of 32 very high mass () galaxy clusters (HIGHMz), selected from the CHEX-MATE sample, to study the intracl…
Design and development of the HERMES Pathfinder payloads
R. Campana, Y. Evangelista, F. Fiore +22
HERMES (High Energy Rapid Modular Ensemble of Satellites) Pathfinder mission aims to observe and localize Gamma Ray Bursts (GRBs) and other transients using a constellation of nano…
Ageing and dynamics of the tailed radio galaxies in Abell 2142
L. Bruno, T. Venturi, D. Dallacasa +11
Context. Tailed radio galaxies are shaped by ram pressure owing to the high-velocity motion of their host through the intracluster medium (ICM). Recent works have reported on the i…
Examining the local Universe isotropy with galaxy cluster velocity dispersion scaling relations
A. Pandya, K. Migkas, T. H. Reiprich +7
In standard cosmology, the late Universe is assumed to be statistically homogeneous and isotropic. However, a recent study based on galaxy clusters by Migkas et al. (2021, arXiv:21…
Axion-like Particle Effects on Photon Polarization in High-Energy Astrophysics
Giorgio Galanti
In this review, we present a self-contained introduction to axion-like particles (ALPs) with a particular focus on their effects on photon polarization: both theoretical and phenom…
On the nature of the 2.4 hr-period eclipsing cataclysmic variable W2 in 47 Tuc
R. Amato, N. La Palombara, M. Imbrogno +5
W2 (CXOGlb J002415.8-720436) is a cataclysmic variable (CV) in the Galactic globular cluster 47 Tucanae. Its modulation was discovered within the CATS@BAR project. The source shows…
Multi-wavelength properties of three new radio-powerful quasi-stellar objects discovered from RACS
L. Ighina, A. Caccianiga, A. Moretti +12
We present a multi-wavelength study of three new quasi-stellar objects (QSOs) identified from dedicated spectroscopic observations. The three sources were selected as hi…
The restless population of bright X-ray sources of NCG 3621
A. Sacchi, M. Imbrogno, S. E. Motta +9
We report on the multi-year evolution of the population of X-ray sources in the nuclear region of NGC 3621 based on Chandra, XMM-Newton and Swift observations. Among these, two sou…
Evaluating the efectiveness of sonifcation in science education using Edukoi
Lucrezia Guiotto Nai Fovino, Anita Zanella, Luca Di Mascolo +4
