The Leo-I group: new dwarf galaxy and UDG candidates

Understand

The study of dwarf galaxies and their environments provides crucial testbeds for predictions of cosmological models and insights on the structure formation on small cosmological scales.

• In recent years, many problems on the scale of groups of galaxies challenged the current standard model of cosmology.
• We aim to increase the sample of known galaxies in the Leo-I group, containing the M\,96 subgroup and the Leo Triplet.
• This galaxy aggregate is located at the edge of the Local Volume at a mean distance of 10.7 Mpc.
