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…

E-INSPIRE -- I. Bridging the gap with the local Universe: Stellar population of a statistical sample of ultra-compact massive galaxies at
John Mills, Chiara Spiniello, Alexey Sergeyev +10
This paper presents the first effort to Extend the Investigation of Stellar Populations In RElics (E-INSPIRE). We present a catalogue of 430 spectroscopically-confirmed ultra-compa…
