Nuclear stellar discs in low-luminosity elliptical galaxies: NGC 4458 and NGC 4478
L. Morelli, C. Halliday, E. M. Corsini +7
We present the detection of nuclear stellar discs in the low-luminosity elliptical galaxies NGC 4458 and NGC 4478, which are known to host a kinematically-decoupled core. Using arc…
Super massive black holes in spiral galaxies: HST/STIS observations for 3 new objects
L. Coccato, E. Dalla Bonta', M. Sarzi +3
We present long-slit HST/STIS measurements of the ionized-gas kinematics in the nucleus of three disk galaxies, namely NGC 2179, NGC 4343, NGC 4435. The sample galaxies have been s…
Ionized gas and stellar kinematics of seventeen nearby spiral galaxies
A. Pizzella, E. M. Corsini, J. C. Vega-Beltran +1
Ionized gas and stellar kinematics have been measured along the major axes of seventeen nearby spiral galaxies of intermediate to late morphological type. We discuss the properties…
The V_c-sigma_c relation in high and low surface brightness galaxies
A. Pizzella, E. Dalla Bonta`, E. M. Corsini +3
We investigate the relation between the asymptotic circular velocity, V_c, and the central stellar velocity dispersion, sigma_c, in galaxies. We consider a new sample of high surfa…
