Pseudo-Dirac neutrinos and relic neutrino matter effect on the high-energy neutrino flavor composition by P.S. Bhupal Dev, Pedro A.N. Machado, Ivan Martínez-Soler

“…We show that if neutrinos are pseudo-Dirac, they can potentially affect the flavor ratio predictions for the high-energy astrophysical neutrino flux observed by IceCube. In this context, we point out a novel matter effect induced by the cosmic neutrino background (CνB) on the flavor ratio composition. …”

The FLUKA code: Overview and new developments by Ballarini Francesca, Batkov Konstantin, Battistoni Giuseppe, Bisogni Maria Giuseppina, Böhlen Till T., Campanella Mauro, Carante Mario P., Chen Daiyuan, De Gregorio Angelica, Degtiarenko Pavel V., De la Torre Luque Pedro, dos Santos Augusto Ricardo, Engel Ralph, Fassò Alberto, Fedynitch Anatoli, Ferrari Alfredo, Ferrari Anna, Franciosini Gaia, Kraan Aafke Christine, Lascaud Julie, Li Wenxin, Liu Juntao, Liu Zhiyi, Magro Giuseppe, Mairani Andrea, Mattei Ilaria, Mazziotta Mario N., Morone Maria C., Müller Stefan E., Muraro Silvia, Ortega Pablo G., Parodi Katia, Patera Vincenzo, Pinsky Lawrence S., Ramos Ricardo L., Ranft Johannes, Rosso Valeria, Sala Paola R., Santana Leitner Mario, Sportelli Giancarlo, Tessonnier Thomas, Ytre-Hauge Kristian S., Zana Lorenzo

“…The FLUKA Monte Carlo Radiation Transport and Interaction code package is widely used to simulate the interaction of particles with matter in a variety of fields, including high energy physics, space radiation, medical applications, radiation protection and shielding assessments, accelerator studies, astrophysical studies and well logging. This paper gives a brief overview of the FLUKA program and describes recent developments, in particular, improvements in the modelling of particle interactions and transport are described in detail. …”

Experimental dynamos: from models to applications to the geodynamo by Pétrélis, François

“…This phenomenon, known as the dynamo effect, is considered to be responsible for most of the magnetic fields of astrophysical objects, including that of the Earth. It took over 80 years after Larmor’s explanation for the first laboratory experiments to demonstrate the dynamo instability. …”

Negative frequencies and negative norms in analogue Hawking radiation systems by Aguero-Santacruz, Raul, Bermudez, David

“…In this work, we study the core concepts of Hawking radiation in the astrophysical and analogue systems. We focus on negative frequencies and negative norms: their definition, their relationship, and their role in the particle creation process of the Hawking effect. …”

Direct imaging of exoplanets: Legacy and prospects by Chauvin, Gael

“…From the astrophysical point of view, it is indeed crucial to understand the mechanisms of formation and evolution of giant planets, including planet and disk interactions, which will completely sculpt the planetary architectures and thus dominate the formation of terrestrial planets, especially in regions around the host star capable of supporting life. …”

Star shearing season: transient signals in wave-like dark matter experiments from black hole formation by Arturo de Giorgi, Joerg Jaeckel

“…This signal can be correlated with the corresponding astrophysical signal of the event. In this note, we consider a variety of couplings and the associated signals and estimate the corresponding sensitivities.…”

Lorentz violation alleviates gravitationally induced entanglement degradation by Wentao Liu, Cuihong Wen, Jieci Wang

“…This suggests that investigating Lorentz violation at astrophysical scales requires low-frequency detectors, as the low energy of these fields enhances the significance of the Lorentz-violating field’s non-zero vacuum expectation value.…”

Internal gravity waves versus inertial waves in the laboratory by Joubaud, Sylvain, Boury, Samuel, Odier, Philippe

“…Density-stratified and/or rotating fluids are very common in geophysical and astrophysical flows and enable the propagation of respectively internal gravity waves and inertial waves. …”

Quasi-biennial oscillation: laboratory experiments by Semin, Benoît, Pétrelis, François

“…This wind is a mean flow induced by atmospheric waves, including internal gravity waves, which explain that the period (28 month) is not linked to any astrophysical forcing. This oscillation has only been reproduced in 3 laboratory experiments, which share a similar geometry. …”

Herrera complexity and shadows of spherically symmetric compact objects by Subhasis Nalui, Subhra Bhattacharya

“…In this context we explore how complexity of compact objects (a fundamentally theoretical classification) is connected to the photon ring (an astrophysical observable in the universe) and its stability. …”
