Ages, metallicity, and alpha-enhancement of the globular cluster populations in NGC 3311
Natalie Grasser, Magda Arnaboldi, Carlos Eduardo Barbosa +3
Aims. We aim to investigate the stellar population properties, ages, and metal content of the globular clusters (GCs) in NGC 3311, the central galaxy of the Hydra I cluster, to bet…
Planetary nebulae as tracers of stellar population properties: unlocking their potential with integral-field spectroscopy
Ana Ennis, Johanna Hartke, Magda Arnaboldi +3
Planetary nebulae (PNe) are essential tracers of the kinematics of the diffuse halo and intracluster light where stellar spectroscopy is unfeasible, due to their strong emission li…
Multi-band analysis of strong gravitationally lensed post-blue nugget candidates from the Kilo-Degree Survey
Rui Li, Nicola R. Napolitano, Linghua Xie +7
During the early stages of galaxy evolution, a significant fraction of galaxies undergo a transitional phase between the ``blue nugget" systems, which arise from the compaction of…
Searching for strong gravitational lenses
Cameron Lemon, Frédéric Courbin, Anupreeta More +9
Strong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered - a task that can be met with significa…
INSPIRE: INvestigating Stellar Population In RElics V. A catalogue of ultra-compact massive galaxies outside the local Universe and their degree of relicness
C. Spiniello, G. D'Ago, L. Coccato +18
This paper presents the third data release of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 52 ultra-compact massive galaxies (UCMGs) observed with t…
Ultra diffuse galaxies in the Hydra I cluster from the LEWIS Project: Phase-Space distribution and globular cluster richness
Duncan Forbes, Jonah Gannon, Enrichetta Iodice +18
Although ultra diffuse galaxies (UDGs) are found in large numbers in clusters of galaxies, the role of the cluster environment in shaping their low surface brightness and large siz…
Looking into the faintEst WIth MUSE (LEWIS): on the nature of ultra-diffuse galaxies in the Hydra-I cluster.I. Project description and preliminary results
Enrichetta Iodice, Michael Hilker, Goran Doll +23
Looking into the faintEst WIth MUSE (LEWIS) is an ESO large observing programme aimed at obtaining the first homogeneous integral-field spectroscopic survey of 30 extremely low-sur…
The elemental abundances of quiescent galaxies in the LEGA-C survey: the (non-)evolution of [α/Fe] from z = 0.75 to z = 0
Davide Bevacqua, Paolo Saracco, Francesco La Barbera +6
We measure the [/Fe] abundances for 183 quiescent galaxies at z = 0.60 - 0.75 with stellar masses ranging 10.4 \leq log10 10.4 log10 (M /M) 11.6 select…
Stellar metallicity from optical and UV spectral indices: Test case for WEAVE-StePS
F. R. Ditrani, M. Longhetti, F. La Barbera +35
The upcoming generation of optical spectrographs on four meter-class telescopes, with their huge multiplexing capabilities, excellent spectral resolution, and unprecedented wavelen…
WEAVE-StePS. A stellar population survey using WEAVE at WHT
A. Iovino, B. M. Poggianti, A. Mercurio +44
The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys through their huge multiplexi…
INSPIRE: INvestigating Stellar Population In RElics IV. The Initial Mass Function slope in relics
I. Martin-Navarro, C. Spiniello, C. Tortora +10
In the last decade, growing evidence has emerged supporting a non-universal stellar Initial Mass Function (IMF) in massive galaxies, with a larger number of dwarf stars with respec…
