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…

COSTA: the COld STream finder Algorithm. Searching for kinematical substructures in the phase space of discrete tracers
M. Gatto, N. R. Napolitano, C. Spiniello +2
Context: We present COSTA (COld STream finder Algorithm), a novel algorithm to search for cold kinematical substructures in the phase space of planetary nebulae (PNe) and globular…

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…
