TL;DR
The MAGIC telescopes conducted the deepest VHE gamma-ray observation of the Perseus galaxy cluster, detecting emissions from NGC 1275 and IC 310, and constraining cosmic-ray emission models.
Contribution
This study provides the first deep VHE gamma-ray survey of a galaxy cluster, detecting emissions and constraining models of cosmic-ray acceleration.
Findings
Detected VHE gamma-ray emissions from NGC 1275 and IC 310
Achieved the deepest VHE observation of a galaxy cluster
Constrained models of cosmic-ray induced gamma-ray emission
Abstract
The MAGIC telescopes performed a deep observation of the central region of the Perseus galaxy cluster in stereoscopic mode between October 2009 and February 2011. The nearly 85 hr of collected data (after quality selection) represent the deepest observation of a cluster of galaxies at very high energies (VHE, E > 100 GeV) ever. The survey resulted in the detection of VHE gamma-ray emissions from its central galaxy NGC 1275 and from the radio galaxy IC 310. In addition, the deep survey also permits for the first time to constrain emission models predicting VHE gamma-rays from cosmic-ray acceleration in the cluster. In this contribution we report the latest MAGIC results concerning these topics.
