AT 2022aedm and a New Class of Luminous, Fast-cooling Transients in Elliptical Galaxies

We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT 2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS). In the ATLAS o band, AT 2022aedm exhibited a rise time of 9 ± 1 days, reaching a luminous peak with M _g ≈ −22 mag. It...
