Invited Talk

Fermi bubbles and the newly discovered eRosita X-ray bubbles are gigantic bubbles above and below the Galactic center (GC) in the Milky Way Galaxy. Their symmetry suggests that they originate from energetic outbursts from the GC; however, whether it is linked to a nuclear starburst or black hole activity has been intensely debated. Here I present our recent results using 3D hydrodynamic...

Invited Talk

With over 14 years of data collection, many dark matter (DM) searches have been performed with Fermi-LAT. Notably, a systematic excess of gamma rays has been detected coming from the Galactic Center (GC) region, and the current leading explanations include mis-modeling of the Galactic diffuse emission along the line of sight, emission from a sub-threshold source population such as millisecond...

152. Gamm-ray Emission from the Sun

Invited Talk

Sustained gamma-ray emission (SGRE) from the Sun represent emission extending up to a day beyond the impulsive phase of solar flares. SGRE was first identified by Forrest et al. (1985) using data from the Solar Maximum Mission’s Gamma-Ray Spectrometer. Only a handful of SGRE events were known over the next thirty years until the advent of the Fermi-Large Area Telescope (LAT). Fermi/LAT has...
