Identification of Candidate Halos Hosting Massive Black Hole Seeds in the Renaissance Simulations with Support Vector Machines

B. Pries, John Wise

Abstract The nature of the origins of supermassive black holes remains uncertain. Multiple possible seeding pathways have been proposed across a variety of mass scales, each with their own strengths and weaknesses. One such channel is a direct collapse black hole (DCBH), …

Search for GeV-scale dark matter from the Galactic Center with IceCube-DeepCore

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

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 high dark matter density, such as the Galactic Center. In this work, we search …

Identification and denoising of radio signals from cosmic-ray air showers using convolutional neural networks

Rasha Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Radio pulses generated by cosmic-ray air showers can be used to reconstruct key properties like the energy and depth of the electromagnetic component of cosmic-ray air showers. Radio detection threshold, influenced by natural and anthropogenic radio background, can be reduced through various …

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

Rasha Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

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 and cascade events from neutrino interactions. We present two analyses sensitive to neutrino events in …

Probing neutrino emission at GeV energies from compact binary mergers with the IceCube Neutrino Observatory

R. Abbasi, M. Ackermann, J. S. Adams, S. K. Agarwalla et autres

The advent of multi-messenger astronomy has allowed for new types of source searches by neutrino detectors. We present the results of the search for 0.5-100 GeV astrophysical neutrinos detected with IceCube and emitted from compact binary mergers detected by the LIGO, Virgo, …

All-sky Neutrino Point-source Search with IceCube Combined Track and Cascade Data

Rasha Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract Despite extensive efforts, discovery of high-energy astrophysical neutrino sources remains elusive. We present an event-level simultaneous maximum likelihood analysis of tracks and cascades using IceCube data collected from 2008 April 6 to 2022 May 23 to search the whole sky for …

Seasonal variations of the atmospheric muon neutrino spectrum measured with IceCube

Rasha Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract This study presents an analysis of seasonal variations in the atmospheric muon neutrino flux, using 11.3 years of data from the IceCube Neutrino Observatory. By leveraging a novel spectral unfolding method, we explore the energy range from 125 GeV to 10 …

The LED calibration systems for the mDOM and D-Egg sensor modules of the IceCube Upgrade: Design, production, testing and use in module calibration

R. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract The IceCube Neutrino Observatory, instrumenting about 1 km 3 of deep, glacial ice at the geographic South Pole, is due to be enhanced with the IceCube Upgrade. The IceCube Upgrade, to be deployed during the 2025/26 Antarctic summer season, will consist …
