Central Galaxy
- Nir Shaviv (Hebrew University of Jerusalem)
The Galactic center (GC) is one of the most important regions to search for a gamma-ray signal from a possible annihilation of dark matter due to its proximity and high dark matter density. In the past years, several groups have reported an excess of gamma rays in the Fermi-LAT data with an approximately spherical morphology around the GC. In this talk I will review the current observational...
Over the last seven years, Fermi-LAT observations have convincingly
found an excess in gamma-ray emission emanating from the center of the
Milky Way galaxy. The excess has three definitive properties: (1) it
has a hard spectrum that peaks at an energy of ~2 GeV, (2) it extends
from within 0.1 degrees to more than 10 degrees from Sgr A* with a
three-dimensional intensity that falls roughly as...
An anomalous excess emission has been found in Fermi-LAT data covering the centre of the Galaxy. We report on an analysis that exploits hydrodynamical modelling to register the position of interstellar gas associated with diffuse Galactic gamma-ray emission. Our analysis reveals that the excess gamma rays’ morphology is statistically well described by the X-shaped stellar over-density in the...
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...
