Description
The Galactic Center (GC) region with its rich and dense astrophysical
environment and a 4 million solar mass black hole (BH) at its center has
always been one of the primary targets for observations with gamma-ray
instruments.
MAGIC has been observing the GC within a multi-year monitoring campaign
since the first reports about the G2 fly-by in 2012. These observations
have been carried out at large zenith angles, leading to a higher energy
threshold but also to increased sensitivity at multi-TeV energies.
I will present the results of the multi-year monitoring program of SgrA*
with the MAGIC telescopes during the time period around and after the
pericentre passage of the G2 object, where MAGIC did not detect any
unusual variability, similar to what has been reported for other
wavelengths. A detailed morphology study of the region, a significant
by-product of the monitoring that became possible due to the
availability of new Fermi tools inspired software for MAGIC data, allows
us to revisit the properties of the GC diffuse emission that recently lead
H.E.S.S. to claim the existence of a PeV cosmic ray source located at
SgrA.
