Studying the AGN radio-neutrino correlation using IceCube and MOJAVE+RFC catalogs

Multi-messenger astronomy is a powerful tool available to researchers to understand astrophysical processes. This was seen on 22 September 2017, when the IceCube neutrino observatory reported a high-energy neutrino event which was found to be coincident with a flaring blazar, TXS 0506+056. This first multi-messenger observation hinted at blazars being sources of observed high-energy astrophysical neutrinos and raised a need for extensive correlation studies. Recent work shows a possibility that the internal absorption of gamma rays, and their interactions intrinsic to the source and with the extragalactic background, will cause a lack of energetic gamma-ray and neutrino correlation while hinting towards a correlation between neutrinos and lower photon energy observations in the X-ray and radio bands. Here, we present our stacking analysis performed using 10 years of IceCube data and the sources reported in the MOJAVE and RFC catalogs. We also talk about how our work compares to other published analyses using public IceCube data.
