Neutrino imaging of the Galactic Centre and Millisecond Pulsar Population
(Journal article; Peer reviewed, 2023)In this work, we consider the possible presence of a large population of millisecond pulsars in the Galactic Centre. Their direct detection would be challenging due to severe pulse broadening caused by scattering of ... -
Prospects for the detection of transient neutrino sources with PLEnuM
(Journal article; Peer reviewed, 2023)The discovery of high-energy astrophysical neutrinos in the TeV-PeV range by IceCube marked the start of neutrino astronomy, and the search for their sources continues. Two promising source candidates have been identified ... -
Ultra-High-Energy Cosmic Rays from a Population of Non-identical Sources
(Journal article; Peer reviewed, 2023)Astrophysical candidates for the sources of ultra-high-energy cosmic rays (UHECRs) exhibit a large diversity in terms of their properties relevant for the acceleration of charged particles, such as luminosity, Lorentz ... -
Disentangling the multi-messenger puzzle of the AGN-starburst composite galaxy NGC 1068
(Journal article; Peer reviewed, 2023)he recent observation of tera electronvolt neutrinos from NGC 1068 has clarified that the dominant high-energy neutrino sources might actually be gamma-ray dim at these energies. But to understand the whole multi-messenger ... -
The origin of optical emission lines in the soft state of X-ray binary outbursts: The case of MAXI J1820+070
(Peer reviewed; Journal article, 2023)The optical emission line spectra of X-ray binaries (XRBs) are thought to be produced in an irradiated atmosphere, possibly the base of a wind, located above the outer accretion disc. However, the physical nature of – and ... -

(Journal article; Peer reviewed, 2023)Complementing the overview contribution about the whitepaper on ultra-high-energy cosmic rays (UHECR) prepared for the Snowmass community survey in the U.S. [Astroparticle Physics 149 (2023) 102819 - arXiv:2205.05845], ... -
The Curious Case of the Maximum Rigidity Distribution of Ultra-high Energy Cosmic-Ray Accelerators
(Journal article; Peer reviewed, 2023)A standard assumption among models of candidate source populations of ultra-high energy cosmic rays (UHECRs) is that all sources in the population accelerate particles to the same maximum energy. Motivated by the fact that ... -

A Gaia view of the optical and X-ray luminosities of compact binary millisecond pulsars
(Peer reviewed; Journal article, 2023)In this paper, we study compact binary millisecond pulsars with low- and very low-mass companion stars (spiders) in the Galactic field, using data from the latest Gaia data release (DR3). We infer the parallax distances ... -
The UHECR contribution of radio galaxies with a finite life-time
(Peer reviewed; Journal article, 2023)The observational data on ultrahigh energy cosmic rays (UHECR), in particular their mass composition, show strong indications for extremely hard spectra of individual mass groups of CR nuclei at Earth. It has been shown ... -
Anisotropy-assisted magnon condensation in ferromagnetic thin films
(Peer reviewed; Journal article, 2024)We theoretically demonstrate that adding an easy-axis magnetic anisotropy facilitates magnon condensation in thin yttrium iron garnet (YIG) films. Dipolar interactions in a quasi-equilibrium state stabilize room-temperature ...
