E-INSPIRE - II. Finding relics from wide-sky multi-band surveys: A proof-of-concept machine learning regression algorithm
Charles Rosen, Chiara Spiniello, John Mills +7
In this second paper of the E-INSPIRE series, we train a machine-learning-based regression on nearby () ultra-compact massive galaxies (UCMGs) with spectroscopical…

INSPIRE: INvestigating Stellar Population In RElics VIII. Emission lines and UV colours in ultra-compact massive galaxies
Chiara Spiniello, Mario Radovich, Anna Ferré-Mateu +13
We report the discovery of emission lines in the optical spectra of ultra-compact massive galaxies (UCMGs) from INSPIRE, including relics, which are the oldest galaxies in the Univ…
