Sources of high-energy astrophysical neutrinos
[arXiv:2402.19314]
We discuss recent results in neutrino astronomy and their implications for the cosmic-ray acceleration in relativistic outflows, such as in Active Galactic Nuclei (AGN) jets, Gamma-Ray Bursts (GRBs), and Tidal Disruption Events (TDEs). We especially focus on challenges at the interface to particle acceleration which can be inferred from the multi-messenger context, such as the paradigm that the sources power the Ultra-High-Energy Cosmic Rays (UHECRs).

Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector
[CERN-EP-2024-248; arXiv:2410.16781]
A search is conducted for a new scalar boson $S$, with a mass distinct from that of the Higgs boson, decaying into four leptons ($\ell =$$e$, $\mu$) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons $Z_\text{d}$: $S \rightarrow Z_\text{d}Z_\text{d} \rightarrow 4\ell$, where the $Z_\text{d}$ boson has a mass between 15 and 300 GeV, and the $S$ boson has a mass between either 30 and 115 GeV or 130 and 800 GeV. The search uses proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider with an integrated luminosity of 139 fb$^{-1}$ at a centre-of-mass energy of $\sqrt{s}=13$ TeV.

AM$^3$: An Open-Source Tool for Time-Dependent Lepto-Hadronic Modeling of Astrophysical Sources
[arXiv:2312.13371]
We present the AM$^3$ (``Astrophysical Multi-Messenger Modeling'') software, which has been successfully used in the past to simulate the multi-messenger emission, including neutrinos, from active galactic nuclei, including the blazar sub-class, gamma-ray bursts, and tidal disruption events. AM$^3$ is a documented state-of-the-art open source software that efficiently solves the coupled integro-differential equations for the spectral and temporal evolution of the relevant particle densities (photons, electrons, positrons, protons, neutrons, pions, muons, and neutrinos).
