Talk	Oral abstract	Title	Multi-frequency and Multi-messenger Astrophysics With Blazars: Recent Results and Predictions for Future Observations with VHE gamma-ray and Neutrino Detectors.
Coauthors
Abstract	I will present some recent multi-frequency and time domain observations of blazars, the only type of extragalactic sources capable of emitting radiation across the entire electromagnetic spectrum, and possibly beyond, through other channels. Blazars are the most powerful and most energetic cosmic accelerators known, so particular attention will be given to the X-ray, gamma-ray and VHE energy bands. In particular, the number of blazar expected to be found in upcoming and mid-term future VHE observations (e.g. Fermi and CTA) will be estimated together with their contribution to the extragalactic backgrounds. Finally, I will describe some recent attempts to open the field of multi-messenger astronomy. This will include the possible association of some of the most energetic blazars with IceCube neutrinos and ultra high energy cosmic rays, and an estimate of the contribution of blazars to the neutrino extragalactic background.
