MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements
Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8
The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…
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…
On unveiling Buried Nuclei with JWST: a technique for hunting the most obscured galaxy nuclei from local to high redshift
I. García-Bernete, F. R. Donnan, D. Rigopoulou +12
We analyze JWST NIRSpec+MIRI/MRS observations of the infrared (IR) Polycyclic Aromatic Hydrocarbon (PAH) features in the central regions (0.26'' at 6 micron; 50-440 pc…
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…
INSPIRE: INvestigating Stellar Population In RElics -- VII. The local environment of ultra-compact massive galaxies
Diana Scognamiglio, Chiara Spiniello, Mario Radovich +15
Relic galaxies, the oldest ultra-compact massive galaxies (UCMGs), contain almost exclusively "pristine" stars formed during an intense star formation (SF) burst at high redshift.…
