| Summary:

[[{“value”:”The satellite populations of Milky Way–mass systems have been extensively
studied, significantly advancing our understanding of galaxy formation and dark
matter physics. In contrast, the satellites of lower-mass dwarf galaxies remain
largely unexplored, despite hierarchical structure formation predicting that
dwarf galaxies should host their own satellites. We present the first results
of the ELVES-Dwarf survey, which aims to statistically characterize the
satellite populations of isolated dwarf galaxies in the Local Volume
($4<D<10$~Mpc). We identify satellite candidates in integrated light using the
Legacy Surveys data and are complete down to $M_gapprox -9$ mag. We then
confirm the association of satellite candidates with host galaxies using
surface brightness fluctuation distances measured from the Hyper Suprime-Cam
data. We surveyed 8 isolated dwarf galaxies with stellar masses ranging from
sub-Small Magellanic Cloud to Large Magellanic Cloud scales ($10^{7.8} <
M_star^{rm host}<10^{9.5}, M_odot$) and confirmed 6 satellites with stellar
masses between $10^{5.6}$ and $10^{8} , M_odot$. Most confirmed satellites
are star-forming, contrasting with the primarily quiescent satellites observed
around Milky Way–mass hosts. By comparing observed satellite abundances and
stellar mass functions with theoretical predictions, we find no evidence of a
"missing satellite problem" in the dwarf galaxy regime.”}]]
