Evidence for an extraterrestrial flux of high-energy neutrinos has now been found in multiple searches with the IceCube detector. The first solid evidence was provided by a search for neutrino events with deposited energies greater than or similar to 30 TeV and interaction vertices inside the instrumented volume. Recent analyses suggest that the extraterrestrial flux extends to lower energies and is also visible with throughgoing, nu(mu)-induced tracks from the Northern Hemisphere. Here, we… 
The IceCube Collaboration has previously discovered a high-energy astrophysical neutrino flux using neutrino events with interaction vertices contained within the instrumented volume of the IceCube
Constraints on Galactic Neutrino Emission with Seven Years of IceCube Data
The origins of high-energy astrophysical neutrinos remain a mystery despite extensive searches for their sources. We present constraints from seven years of IceCube Neutrino Observatory muon data on

IceCube detects neutrinos at energies orders of magnitude higher than any neutrinos produced at particle accelerators. Neutrinos are weakly interacting particles but at energies above 30 TeV the
Discovery and characterization of a diffuse astrophysical muon neutrino flux with the iceCube neutrino observatory
The IceCube Collaboration has previously discovered a flux of high-energy astrophysical neutrinos whose measurement is based on events with interaction vertices contained within the IceCube detector.
Extracting the Energy-Dependent Neutrino-Nucleon Cross Section above 10 TeV Using IceCube Showers.
Using six years of public IceCube High-Energy Starting Events, it is explicitly shown for the first time that the energy dependence of the cross section above 18 TeV agrees with the predicted softer-than-linear dependence, and reaffirm the absence of new physics that would make the crossSection rise sharply, up to a center-of-mass energy sqrt[s]≈1  TeV.
Time Integrated searches for Astrophysical Neutrino Sources using the IceCube Detector and Gender in Physics studies for the Genera Project
This thesis presents point-like neutrino source searches using ten years of IceCube data collected between Apr.~6, 2008 to Jul.~10, 2018. These searches evaluate the significance of an astrophysical
Measurement of the Energy-Dependent Neutrino-Nucleon Cross Section Above 10 TeV Using IceCube Showers
Neutrinos are key to probing the deep structure of matter and the high-energy Universe. Yet, until recently, their interactions had only been measured at laboratory energies up to about 350 GeV. An
A search for neutrino emission from cores of Active Galactic Nuclei
The sources of the majority of the high-energy astrophysical neutrinos observed with the IceCube neutrino telescope at the South Pole are unknown. So far, only a gamma-ray blazar was compellingly

Since the detection of high-energy cosmic neutrinos at the IceCube Neutrino Observatory in 2013, there has been an on-going search to find the origins of this flux. Despite recent evidence


Observation of high-energy astrophysical neutrinos in three years of IceCube data.
Results from an analysis with a third year of data from the complete IceCube detector are consistent with the previously reported astrophysical flux in the 100 TeV-PeV range at the level of 10(-8)  GeV cm-2 s-1 sr-1 per flavor and reject a purely atmospheric explanation for the combined three-year data at 5.7σ.
Search for a diffuse flux of astrophysical muon neutrinos with the IceCube 59-string configuration
A search for high-energy neutrinos was performed using data collected by the IceCube Neutrino Observatory from May 2009 to May 2010, when the array was running in its 59-string configuration. The
Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector
The presence of a high-energy neutrino flux containing the most energetic neutrinos ever observed is revealed, including 28 events at energies between 30 and 1200 TeV, although the origin of this flux is unknown and the findings are consistent with expectations for a neutRino population with origins outside the solar system.
Atmospheric and Astrophysical Neutrinos above 1 TeV Interacting in IceCube
The IceCube Neutrino Observatory was designed primarily to search for high-energy (TeV-PeV) neutLrinos produced in distant astrophysical objects. A search for. greater than or similar to 100 TeV
Spectral analysis of the high-energy IceCube neutrinos
A full energy and flavor-dependent analysis of the three-year high-energy IceCube neutrino events is presented. By means of multidimensional fits, we derive the current preferred values of the
Search for neutrino-induced particle showers with IceCube-40
We report on the search for neutrino-induced particle showers, so-called cascades, in the IceCube-40 detector. The data for this search were collected between April 2008 and May 2009 when the first
First search for atmospheric and extraterrestrial neutrino-induced cascades with the IceCube detector
We report on the first search for atmospheric and for diffuse astrophysical neutrino-induced showers (cascades) in the IceCube detector using 257 days of data collected in the year 2007-2008 with 22
Searches for point-like and extended neutrino sources close to the galactic center using the antares neutrino telescope

Photohadronic Origin of the TeV-PeV Neutrinos Observed in IceCube
We perform an unbiased search of the origin of the recently observed 28 events above ~30 TeV in the IceCube neutrino observatory, assuming that these are (apart from the atmospheric background) of
Flavor composition of the high-energy neutrino events in IceCube.
The IceCube experiment has recently reported the observation of 28 high-energy neutrino events, separated into 21 showers and 7 muon tracks, consistent with an extraterrestrial origin, which is found to suggest either a misunderstanding of the expected background events or a misidentification of tracks as showers, or even more compellingly, some exotic physics which deviates from the standard scenario.
