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…
