Pushing Variability Searches to Extreme Dwarf Galaxies with the Vera C. Rubin Observatory Data Preview 2
Researchers searched for variable extreme dwarf galaxies (EDGs) in a specific field using Vera C. Rubin Observatory data preview 2. They found seven variable EDG candidates brighter than i-band magnitude 24, suggesting they might be AGNs or supernovae. This indicates that optical variability in these faint galaxies is detectable with limited observations.
