LMC 0.2-100GeV images
Listed in IVOA Registry (Virtual Observatory)
The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in {gamma}-rays.
Description
The LMC was detected at 0.1-100GeV as an extended source with CGRO/EGRET and using early observations with the Fermi-LAT. The emission was found to correlate with massive star-forming regions and to be particularly bright towards 30 Doradus.
Studies of the origin and transport of cosmic rays (CRs) in the Milky Way are frequently hampered by line-of-sight confusion and poor distance determination. The LMC offers a complementary way to address these questions by revealing whether and how the {gamma}-ray emission is connected to specific objects, populations of objects, and structures in the galaxy. We revisited the {gamma}-ray emission from the LMC using about 73 months of Fermi-LAT P7REP data in the 0.2-100GeV range.

We developed a complete spatial and spectral model of the LMC emission, for which we tested several approaches: a simple geometrical description, template-fitting, and a physically driven model for CR-induced interstellar emission.
