Descrição
Nowadays, up to 50 Dwarf Galaxies have been found by actual detectors. However, new generation experiments like the Vera Rubin telescope will be able to detect many more of these objects (called the faint dwarf galaxies).
On the other hand the SWGO detector (english abbreviation of The Southern Wide-field
Gamma-ray Observatory ), is a new gamma ray telescope which will be located on the Southern Hemisphere in South America. Its main goal is to improve the detection of photons arriving at its location, because for the moment experiments of this type are settled mainly on the other hemisphere.
One of the most interesting problems among the astrophysics community is the Dark Matter.
There is indirect evidence of their existence coming from gravitational effects observed
in galaxies, galaxy clusters, gravitational lenses and cosmic microwave background. However its nature remains elusive due the lack of a direct detection.
One possible scenario is the annihilation of dark matter into standard model particles.
If this scenario happens, dwarf galaxies offer a very good opportunity to detect or constrain dark matter properties due to its properties: less quantity of stars and a significant amount of dark matter.
As part of the SWGO collaboration, we want to present in this poster the advances in our research project about the SWGO detection of dark matter including the faint dwarf galaxies, taking into account 10 possible substructure models proposed initially by:
Maria Kherlakian, Aion Viana and Vitor de Souza. JCAP03(2023)025.
