Observational distinguishability of the Kerr and Kerr-Hayward metrics to EHT

Nikola Bukowiecka, Angelo Ricarte, Prashant Kocherlakota +1

Astrophysical black holes appear well-represented by the Kerr metric, whose maximal analytic extension contains a ringlike curvature singularity. We study a phenomenological regula…

Approximating the Fourier Transform of Ring-Like Images: the Focal Expansion

Filip Niewiński, Michael D. Johnson

We derive and showcase a novel approach to approximating Fourier transforms in higher dimensions, focusing specifically on the case of 2D radially concentrated ('ring-like') functi…

Search for GeV-scale Dark Matter from the Galactic Center with IceCube-DeepCore

The IceCube Collaboration, R. Abbasi, M. Ackermann +431

Models describing dark matter as a novel particle often predict that its annihilation or decay into Standard Model particles could produce a detectable neutrino flux in regions of…

Polarization Signatures of Inspiraling Hotspots around Kerr Black Holes

Pablo Ruales, Delilah E. A. Gates, Alejandro Cárdenas-Avendaño

Polarimetric interferometry is a powerful tool for probing both black hole accretion physics and the background spacetime. Current models aimed at explaining the observed multiwave…

Pulsar scintillation arcs formed from correlated volume scattering

Tobias Kramer

Radio waves propagating through the interstellar medium are influenced by variations in plasma density. For spatially localised plasma structures along the line of sight, time-dela…

Improved measurements of the TeV-PeV extragalactic neutrino spectrum from joint analyses of IceCube tracks and cascades

R. Abbasi, M. Ackermann, J. Adams +424

The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks an…
