The Fornax 3D project: dust mix and gas properties in the center of early-type galaxy FCC 167
S. Viaene, M. Sarzi, N. Zabel +15
Galaxies continuously reprocess their interstellar material. One can therefore expect changing dust grain properties in galaxies which have followed different evolutionary pathways…
A catalogue of nuclear stellar velocity dispersions of nearby galaxies from H STIS spectra to constrain supermassive black hole masses
I. Pagotto, E. M. Corsini, M. Sarzi +4
We present new measurements for the nuclear stellar velocity dispersion within sub-arcsecond apertures for 28 nearby galaxies. Our data consist of Space Telescope Imagin…
Near Infrared spectroscopic indices for unresolved stellar populations. I. Template galaxy spectra
P. Francois, L. Morelli, A. Pizzella +5
A new generation of spectral synthesis models has been developed in the recent years, but there is no matching -- in terms of quality and resolution -- set of template galaxy spect…
Fossil group origins IX. Probing the formation of fossil galaxy groups with stellar population gradients of their central galaxies
E. M. Corsini, L. Morelli, S. Zarattini +7
Fossil groups (FGs) are galaxy aggregates with an extended and luminous X-ray halo, which are dominated by a very massive early-type galaxy and lack of L* objects. FGs are indeed c…
Evidence for the formation of the young counter-rotating stellar disk from gas acquired by IC 719
Alessandro Pizzella, Lorenzo Morelli, Lodovico Coccato +4
The formation scenario of extended counter-rotating stellar disks in galaxies is still debated. In this paper, we study the S0 galaxy IC 719 known to host two large-scale counter-r…
