Table 1
Number of dwarf galaxy candidates within the UNIONS footprint and their distance ranges, compiled from the listed literature catalogs.
| Catalog | Number of objects | Distance (Mpc) |
|---|---|---|
| ELVES | 49 | <12 |
| MATLAS | 315 | ∼ 10−45 |
| SAGA | 27 | 25−40.75 |
| SMUDGES | 1212 | ≲ 143 |
| NGC5485 UDGs | 4 | ∼ 27 |
| dEs Local Universe | 402 | ≲40 |
Notes. References for these are ELVES (Carlsten et al. 2022), MATLAS (Duc et al. 2015; Bílek et al. 2020; Habas et al. 2020; Poulain et al. 2021), SAGA (Geha et al. 2017; Mao et al. 2021, 2024), SMUDGES (Zaritsky et al. 2019; Goto et al. 2023; Zaritsky et al. 2023), NGC5485 UDGs (Merritt et al. 2014), and dEs Local Universe (Paudel et al. 2023). Note: for the majority of objects (except ELVES and SAGA), distances are predominantly estimated based on their assumed association with a host galaxy for which the spectroscopic redshift or direct distance measurements are available.
