The discovery of extreme brightness in blazars, made with space VLBI observations, has set new limits on the very high rates of energy release in plasma and a very efficient particle acceleration. The mounting observational indications for extragalactic neutrino production in blazar-type AGN now begin to deliver key understanding about the physics of proton acceleration in blazars, either nearby ...

Blazars are found to cover a broad range in luminosity and the lowest-luminosity objects turn out to be the ones whose spectral energy distribution extends to the highest energies. In the most extreme blazars their spectral energy distribution can peak at very high gamma-ray energies above 10 TeV. These extremely high peaked BL Lac objects typically are faint radio sources and thus make up a poorl ... More

Neutrinos are a unique and complementary messenger to probe the high-energy universe. I will introduce the currently operating neutrino telescopes, and review what we have learned about the spectrum, flavor composition and sources of astrophysical neutrinos since their discovery in 2013. I will also give a glimpse into the future of the field and the scientific potential of new instrumentation env ... More

In recent years, evidence has accumulated that some high-energy cosmic neutrinos may be associated with blazars. The strongest evidence for an individual association was found in the case of the blazar TXS 0506+056 which exhibited a major multi-wavelength flare coinciding with an IceCube neutrino event in 2017. A major open question is the production site of neutrinos in blazar jets, especially th ... More
