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.…

Asymmetric drift in MaNGA: Mass and radially-dependent stratification rates in galaxy disks
Matthew A. Bershady, Kyle B. Westfall, Shravan Shetty +5
We measure the age-velocity relationship from the lag between ionized gas and stellar tangential speeds in ~500 nearby disk galaxies from MaNGA in SDSS-IV. Selected galaxies are ki…
