Search for gamma-ray emission from the nearby dwarf spheroidal galaxies with 9 years of Fermi-LAT data
In this work, we search for $\ensuremath{\gamma}$-ray emission from nearby Milky Way dwarf spheroidal galaxies (dSphs) and candidates with the publicly available Pass 8 data of Fermi-LAT. Our sample includes 12 sources with the distances $<50\text{ }\text{ }\mathrm{kpc}$. Very weak $\ensuremath{\gamma}$-ray excesses ($\ensuremath{\sim}2\ensuremath{\sigma}$) are found in some dSphs/candidates, consistent with …
