Further evidence for a time-dependent initial mass function in massive early-type galaxies
I. Ferreras, C. Weidner, A. Vazdekis +1
Spectroscopic analyses of gravity-sensitive line strengths give growing evidence towards an excess of low-mass stars in massive early-type galaxies (ETGs). Such a scenario requires…
Mass accretion rates from multi-band photometry in the Carina Nebula: the case of Trumpler 14
G. Beccari, G. DeMarchi, N. Panagia +5
We present a study of the mass accretion rates of pre-Main Sequence (PMS) stars in the cluster Trumpler 14 (Tr14) in the Carina Nebula. Using optical multi-band photometry we were…
Sampling methods for stellar masses and the mmax-Mecl relation in the starburst dwarf galaxy NGC 4214
Carsten Weidner, Pavel Kroupa, Jan Pflamm-Altenburg
It has been claimed in the recent literature that a non-trivial relation between the mass of the most-massive star, mmax, in a star cluster and its embedded star cluster mass (the…
Chemo-Archaeological Downsizing in a Hierarchical Universe: Impact of a Top Heavy IGIMF
I. D. Gargiulo, S. A. Cora, N. D. Padilla +6
We make use of a semi-analytical model of galaxy formation to investigate the origin of the observed correlation between [a/Fe] abundance ratios and stellar mass in elliptical gala…
The galaxy-wide IMF of dwarf late-type to massive early-type galaxies
Carsten Weidner, Pavel Kroupa, Jan Pflamm-Altenburg +1
Observational studies are showing that the galaxy-wide stellar initial mass function are top-heavy in galaxies with high star-formation rates (SFRs). Calculating the integrated gal…
The (galaxy-wide) IMF in giant elliptical galaxies: From top to bottom
Carsten Weidner, Ignacio Ferreras, Alexandre Vazdekis +1
Recent evidence based independently on spectral line strengths and dynamical modelling point towards a non-universal stellar Initial Mass Function (IMF), probably implying an exces…
