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…

CORN -- Chronometers of Relic Nature I: The first estimate of the expansion rate of the Universe using compact relic galaxies

Krzysztof Lisiecki, Nicola Principi Cavaterra, Agnieszka Pollo +9

Measuring the expansion rate of the Universe is a central challenge in cosmology. Independent and robust methods are essential to validate existing measurements and assess potentia…

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…

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…
