Starburst galaxy

The gamma ray spectra of starburst galaxies are important to understand the physical emission scenario, and to extend the study of the relationship between star forming process and gamma-ray emission to extragalactic environment. Infact, cosmic rays may play a major role in the regulation of the star-formation processes, so it is important to understand where they are accelerated, how they propagate and where they interact in the interstellar medium.

Another important topic, recently raised by FERMI and investigated by MAGIC, is the gamma-ray flux observed in some AGNs and possibly related to massive molecular outflows that are shedding light on the role of AGN drivers winds in regulating galaxy growth and environment. The ACDC simulation take into account the different mechanisms of the coupling between the energy output and the gas in the host galaxy, in order to provide a possible targets for ASTRI mini array and CTA

Colour composite image of Centaurus A. The submillimetre data, from LABOCA on APEX, are shown in orange. X-ray data from the Chandra X-ray Observatory are shown in blue. Visible light data from the Wide Field Imager (WFI) on the MPG/ESO 2.2 m telescope located at La Silla, Chile, show the background stars and the galaxy’s characteristic dust lane in close to "true colour".
