Smoothed Particle Hydrodynamics in Astrophysics [PDF]

Annual Review of Astronomy and Astrophysics, 2010
This review discusses smoothed particle hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formulation of hydrodynamics that has excellent conservation properties and can be coupled to self-gravity with high accuracy.

Artificial intelligence for improved fitting of trajectories of elementary particles in dense materials immersed in a magnetic field

Communications Physics, 2023
Particle track fitting is crucial for understanding particle kinematics. In this article, we use artificial intelligence algorithms to show how to enhance the resolution of the elementary particle track fitting in dense detectors, such as plastic ...

Particle acceleration in astrophysical sources [PDF]

Proceedings of Frontiers of Fundamental Physics 14 — PoS(FFP14), 2016
Astrophysical sources are extremely efficient accelerators. Some sources emit photons up to multi-TeV energies, a signature of the presence, within them, of particles with energies much higher than those achievable with the largest accelerators on Earth.

The Type IIn SN 2025cbj coincidence with the high-energy neutrino IceCube-250421A

Astronomy & Astrophysics
Context. The origins of astrophysical high-energy neutrino flux remain uncertain. Core-collapse supernovae (CCSNe) with strong circumstellar material (CSM) interactions (i.e., Type IIn, a.k.a.

Towards a full solution of the large N double-scaled SYK model

Journal of High Energy Physics, 2019
We compute the exact, all energy scale, 4-point function of the large N doublescaled SYK model, by using only combinatorial tools and relating the correlation functions to sums over chord diagrams. We apply the result to obtain corrections to the maximal

Astrophysical Particle Acceleration [PDF]

Progress of Theoretical Physics Supplement, 2003
Nonthermal particle acceleration is one of the most important topics in physics of cosmic plasmas. The heliosphere has been playing the role of the astrophysical laboratory for particle acceleration processes, where the basic ideas on various physical mechanisms can be tested against the data from in situ observations.

Testing minimal flavor violation in leptoquark models of the RK∗ $$ {R_K}_{{}^{\left(\ast \right)}} $$ anomaly

Journal of High Energy Physics, 2017
The RK∗ $$ {R_K}_{{}^{\left(\ast \right)}} $$ anomaly can be explained by tree level exchange of leptoquarks. We study the consequences of subjecting these models to the principle of minimal flavor violation (MFV).

Searching for Earth/Solar axion halos

Journal of High Energy Physics, 2020
We discuss the sensitivity of the present and near-future axion dark matter experiments to a halo of axions or axion-like particles gravitationally bound to the Earth or the Sun. Such halos, assuming they are formed, can be searched for in a wide variety
