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…
INSPIRE: INvestigating Stellar Population In RElics III. Second data release (DR2): testing the systematics on the stellar velocity dispersion
G. D'Ago, C. Spiniello, L. Coccato +15
This is the second data release (DR2) of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 21 new systems with observations completed before March 2022.…
The star formation history and the nature of the mass-metallicity relation of passive galaxies at 1.0<z<1.4 from VANDELS
Paolo Saracco, Francesco La Barbera, Roberto De Propris +9
We derived stellar ages and metallicities [Z/H] for 70 passive early type galaxies (ETGs) selected from VANDELS survey over the redshift range 1.01.4 and stellar mas…
Galaxy populations in the Hydra I cluster from the VEGAS survey I. Optical properties of a large sample of dwarf galaxies
Antonio La Marca, Reynier Peletier, Enrichetta Iodice +17
At ~50 Mpc, the Hydra I cluster of galaxies is among the closest cluster in the z=0 Universe, and an ideal environment to study dwarf galaxy properties in a cluster environment. We…
What does (not) drive the variation of the low-mass end of the stellar initial mass function of early-type galaxies
C. E. Barbosa, C. Spiniello, M. Arnaboldi +3
The stellar initial mass function (IMF) seems to be variable and not universal, as argued in the literature in the last three decades. Several relations among the low-mass end of t…
Are the total mass density and the low-mass end slope of the IMF anti-correlated?
C. Spiniello, M. Barnabè, L. V. E. Koopmans +1
We conduct a detailed lensing, dynamics and stellar population analysis of nine massive lens early-type galaxies (ETGs) from the X-Shooter Lens Survey (XLENS). Combining gravitatio…
