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…
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…
Shaping the diffuse X-ray sky: Structure, Variability and Visibility
Philipp Girichidis, Erika Rea, Ralf S. Klessen +5
The Local Bubble (LB) is a hot, low-density cavity in the solar neighborhood, inside which the Solar System is currently located. The X-ray emission from such bubbles is strongly g…
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…
Optimizing the potential of KM3NeT in detecting core-collapse supernovae
KM3NeT Collaboration, O. Adriani, A. Albert +285
Core-collapse supernovae mark the end of life of massive stars. However, despite their importance in astrophysics, their underlying mechanisms remain unclear. Neutrinos that emerge…
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…
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…
Evidence for a Spectral Break or Curvature in the Spectrum of Astrophysical Neutrinos from 5 TeV--10 PeV
R. Abbasi, M. Ackermann, J. Adams +424
We report improved measurements of the all flavor astrophysical neutrino spectrum with IceCube by combining complementary neutrino samples in two independent analyses. Both analyse…
Constraints on the diffuse flux of multi-PeV astrophysical neutrinos obtained with the Baikal Gigaton Volume Detector
V. A. Allakhverdyan, A. D. Avrorin, A. V. Avrorin +69
Various theoretical models predict cosmic neutrinos with multi-PeV energies. The recent detection of a ~10^17 eV neutrino in the KM3NeT experiment suggests that these energetic par…
Seasonal Variations of the Atmospheric Muon Neutrino Spectrum measured with IceCube
R. Abbasi, M. Ackermann, J. Adams +425
This study presents an energy-dependent analysis of seasonal variations in the atmospheric muon neutrino spectrum, using 11.3 years of data from the IceCube Neutrino Observatory. B…
Search for Extremely-High-Energy Neutrinos and First Constraints on the Ultrahigh-Energy Cosmic-Ray Proton Fraction with IceCube
IceCube Collaboration, R. Abbasi, M. Ackermann +423
We present a search for the diffuse extremely-high-energy neutrino flux using years of IceCube data. The nonobservation of neutrinos with energies well above $10 \, \mathrm{…
Origin of spectral bands in the Crab pulsar radio emission
Mikhail V. Medvedev
The model explaining the spectral "zebra" pattern of the high-frequency interpulse (HFIP) of the Crab pulsar radio emission is proposed. The observed emission bands are diffraction…
Jet Archaeology and Forecasting: Image Variability and Magnetic Field Configuration
Yuh Tsunetoe, Ramesh Narayan, Angelo Ricarte
We investigate how magnetic field variations around accreting black holes on event horizon scales affect the morphology of magnetically-driven jet on larger scales. By performing r…
Bayesian Black Hole Photogrammetry
Dominic O. Chang, Michael D. Johnson, Paul Tiede +1
We propose a simple, analytic dual-cone accretion model for horizon scale images of the cores of Low-Luminosity Active Galactic Nuclei (LLAGN), including those observed by the Even…
Milli-to-Deci-Hertz Detection Prospects for Gravitational Waves from Core-Collapse Supernovae
Kiranjyot Gill
Gravitational wave (GW) astronomy truly began with the detection of merging compact binaries. The next breakthrough lies in detecting GWs from core-collapse supernovae (CCSNe), par…
Accretion Flares from Stellar Collisions in Galactic Nuclei
Betty X. Hu, Avi Loeb
The strong tidal force in a supermassive black hole's (SMBH) vicinity, coupled with a higher stellar density at the center of a galaxy, make it an ideal location to study the inter…
Characterization of the Astrophysical Diffuse Neutrino Flux using Starting Track Events in IceCube
R. Abbasi, M. Ackermann, J. Adams +415
A measurement of the diffuse astrophysical neutrino spectrum is presented using IceCube data collected from 2011-2022 (10.3 years). We developed novel detection techniques to searc…
Scattering model of scintillation arcs in pulsar secondary spectra
Tobias Kramer, Daniel Waltner, Eric J. Heller +1
The dynamic spectra of pulsars frequently exhibit diverse interference patterns, often associated with parabolic arcs in the Fourier-transformed (secondary) spectra. Our approach d…
Misaligned magnetized accretion flows onto spinning black holes: Magneto-spin alignment, outflow power, and intermittent jets
Koushik Chatterjee, Nicholas Kaaz, Matthew Liska +2
Magnetic fields regulate black hole (BH) accretion, governing both inflow and outflow dynamics. When a BH accumulates substantial vertical magnetic flux, it enters the magnetically…
