Sterile neutrino searches at the Icecube Neutrino Observatory
The IceCube Neutrino Observatory is capable of performing a unique search for sterile neutrinos through the exploitation of a matter enhanced resonant neutrino oscillation phenomena. As atmospheric muon neutrinos pass the dense material within the Earth, neutral current elastic forward scattering …

Through Iron & Ice: Searching for Sterile Neutrinos at the IceCube Neutrino Observatory
… second analysis is the results of an expanded IceCube sterile neutrino search. A previous sterile neutrino search found no evidence for sterile neutrinos, finding a p-value of 8%. Of the three sterile mixing angles, 𝜃_14,𝜃_24, and 𝜃_34, only 𝜃_24 was fitted for, as 𝜃_14 was negligible and 𝜃_34 …

A Search for Muon Neutrinos from Gamma-Ray Bursts wih the IceCube 22-String Detector
… neutrinos from Gamma-Ray Bursts (GRBs) using the IceCube detector. Gamma-Ray Bursts are brief and transient emissions of keV/MeV radiation occuring with a rate of a few per day uniformly in the sky. Swift and other satellites of the Third Interplanetary Network (IPN3) detect these GRBs and send …

Light, Unstable Sterile Neutrinos: Phenomenology, a Search in the IceCube Experiment, and a Global Picture
… of unstable sterile neutrinos is explored in the IceCube experiment, a gigaton neutrino detector located at the South Pole. Second, global fits to traditional and unstable sterile neutrino models are combined with one year of data from IceCube. A preference for the unstable sterile neutrino model …

All-Sky Search for Neutrinos Correlated with Gamma-Ray Bursts in Extended Time Windows Using Eight Years of IceCube Data
… sources of the diffuse neutrino flux measured by IceCube. This thesis presents a search for neutrinos correlated with 2,091 gamma-ray bursts (GRBs) in prompt and extended time windows using data from the IceCube Neutrino Observatory ranging from May 2011 to October 2018. Ten time windows, ranging …

Sterile Neutrino Searches
… indications from the experiments Neutrino-4 and IceCube. In the second part of the thesis we discuss the current status of sterile neutrino searches at nuclear reactors, we present a study with the optimization of a green field, two baseline reactor experiment with respect to the sensitivity for …

SEARCH FOR GAMMA-RAY COUNTERPARTS OF GRAVITATIONAL WAVE EVENTS AND OTHER TRANSIENT SIGNALS WITH HAWC
… efforts led to a set of neutrinos detected by IceCube to be associated with the blazar TXS 0506+056. Both demonstrate the potential of using multiple types of probes to study an astrophysical source. The High-Altitude Water Cherenkov Observatory (HAWC), located in the state of Puebla, Mexico, …

Sterile neutrinos in cold climates
… a search for sterile neutrinos using the IceCube neutrino telescope, which has collected a large sample of atmospheric-neutrino-induced events in the 1-10 TeV energy range. Sterile neutrinos would modify the detected neutrino flux shape via MSW-resonant oscillations. Following a careful …

Targets of opportunity source catalog, prioritization, scheduler and related mechanics for the EUSO-SPB2 mission, The
… PeV energies, ground-based detectors such as IceCube and ANTARES have utilized km3-scale mediums to observe these EASs via their optical Cherenkov emissions. However, at higher energies, much of the sky becomes inaccessible to ground-based detectors because of Earth attenuation effects. As the …

Feasibility of acoustic neutrino detection with the South Pole Acoustic Test Setup
… of the kilometer-scale neutrino detector, IceCube. However, the optical attenuation length and therefore detector cost is prohibitive to a possible extension towards the even larger detector volumes that are needed to detect the astrophysical neutrinos of the highest energies. Both the …
