Reply to a comment on `Understanding the gamma-ray emission from the globular cluster 47 Tuc: evidence for dark matter?'
Anthony M. Brown, Thomas Lacroix, Sheridan Lloyd +2
Analysing 9 years of Fermi-LAT observations, we recently studied the spectral properties of the prominent globular cluster 47 Tuc (Brown et al. 2018). In particular, we investigate…
Using Circular Polarisation to Test the Composition and Dynamics of Astrophysical Particle Accelerators
Céline Boehm, Céline Degrande, Jakub Scholtz +1
We investigate the production of circularly polarised X and gamma-ray signals in cosmic accelerators such as supernova remnants and AGN jets. Proton-proton and proton-photon collis…
Discovery of a new extragalactic source population of energetic particles
Anthony M. Brown, Celine Bœhm, Jamie Graham +3
We report the discovery of a statistically significant hardening in the Fermi-LAT -ray spectrum of Centaurus A's core, with the spectral index hardening from $Γ_{1}=2.73 \pm 0.0…
The Spatial Morphology of the Secondary Emission in the Galactic Center Gamma-Ray Excess
Thomas Lacroix, Oscar Macias, Chris Gordon +3
Excess GeV gamma rays from the Galactic Center (GC) have been measured with the Fermi Large Area Telescope (LAT). The presence of the GC excess (GCE) appears to be robust with resp…
