[Vernesa Smolcic]

> Postovani kolege,
> 
> u utorak, 15.9. odrzat ce se na Fizickom odsjeku u prostoriji F-08 u 14:15 sati znanstveni seminar Hrvatskog fizikalnog drustva:
> 
> Paolo Padovani, European Southern Observatory, Garching, Njemacka
> 
> Particle Physics meets Astrophysics:  Astrophysical counterparts of IceCube neutrinos
> 
> IceCube has recently reported the discovery of high-energy neutrinos of
> astrophysical origin, opening up the PeV (10^15 eV) sky. These observations 
> are challenging to interpret on the astronomical side and have triggered a fruitful 
> collaboration across particle and astro-physics. I will make the case for BL Lacertae objects 
> to be the counterparts of at least some of the IceCube neutrinos based on: 1. a joint positional 
> and energetic diagnostic that makes use of high-energy source catalogues and 2. a theoretical 
> modelling of their spectral energy distributions within a lepto-hadronic scenario. I will then 
> extrapolate our findings from individual sources to the whole BL Lacertae class by employing 
> sophisticated Monte Carlo simulations, which reproduce all the main properties of these sources 
> in the radio, X-ray, and gamma-ray bands. Based on this, I will present a detailed calculation of 
> the neutrino astrophysical background (diffuse intensity) from the whole BL Lacertae class and discuss 
> its specific predictions, which should be testable in the next few years by further IceCube data.
> The talk is self-contained, requires no previous knowledge of neutrinos or BL Lacertae objects, 
> and has been prepared for a mixed audience of physicists and astronomers.

> Lijep pozdrav,
