IceCube Search for High-Energy Neutrinos from Obscured Sources in the Great Observatories All-Sky LIRG Survey (GOALS)

Project Details

Description

The discovery of high-energy cosmic neutrinos by the IceCube
collaboration in 2013 started the quest to unravel their origin.
Multimessenger observations of both neutrinos and gamma rays
show that the contribution of gamma-ray bright objects to the
observed diffuse astrophysical neutrino flux is largely constrained.
This has lead the IceCube group at the IIHE-VUB to propose
gamma-ray dim objects, obscured by large amounts of dust and gas,
as candidate sources of astrophysical neutrinos. The PhD project
proposed here outlines an IceCube search for astrophysical
neutrinos from objects within the Great Observatories All-Sky LIRG
Survey (GOALS). GOALS objects are among the brightest infrared
sources in the Universe, containing a tremendous energy budget
combined with extreme amounts of obscuring matter. These two key
features make GOALS objects excellent candidate neutrino sources
that can contribute to the diffuse neutrino flux measured by IceCube
