Some Comments on the High Energy Emission from Regions of Star Formation beyond the Galaxy∗
Regions that currently are or have been subject to a strong process of star formation are good candidates to be intense γ-ray and neutrino emitters. They may even perhaps be sites where ultra high energy cosmic rays are produced. Outside the Galaxy, the more powerful sites of star formation are found within very active galaxies such as starbursts (SGs) and Luminous or Ultra-Luminous Infrared Ga...
متن کاملGalactic very high energy sources and enhancements of material content
The association of very-high energy (VHE; E > 100GeV) sources with regions of the sky rich in dust and gas has been noticed in the study of individual VHE sources. However, the statistical significance of this correlation for the whole population of TeV detections has not been assessed yet. To trace the material content, we make use of the publicly released all-sky maps of astrophysical foregro...
متن کاملThe diffuse neutrino flux from the inner Galaxy: constraints from very high energy gamma-ray observations
Recently, the MILAGRO collaboration reported on the detection of a diffuse multiTeV emission from a region of the Galactic disk close to the inner Galaxy. The emission is in excess of what is predicted by conventional models for cosmic ray propagation, which are tuned to reproduce the spectrum of cosmic rays observed locally. By assuming that the excess detected by MILAGRO is of hadronic origin...
متن کاملThe H . E . S . S . survey of the Inner Galaxy in very - high - energy gamma - rays
We report on a survey of the inner part of the Galactic Plane in very high energy γ-rays with the H.E.S.S. Cherenkov telescope system. The Galactic Plane between ±30 in longitude and ±3 in latitude relative to the Galactic Centre was observed in 500 pointings for a total of 230 hours, reaching an average flux sensitivity of 2% of the Crab Nebula at energies above 200 GeV. Fourteen previously un...
متن کاملThe Center of Our Galaxy: Activity and High-energy Emission of the Closest Massive Black Hole
The Center of our Galaxy is a peculiar region where a number of crucial astrophysical phenomena take place, from star formation to SN explosions and accretion onto a massive black hole. The quest for a massive black hole in the Galactic Nucleus is of course of particular relevance because, it would be the closest of such extreme objects, which are now believed to reside in most of the galactic ...
