    • A census of nuclear stellar discs in early-type galaxies 

      Ledo, H.R.; Sarzi, M.; Dotti, M.; Khochfar, S.; Morelli, L. (2010)
      Nuclear stellar discs (NSDs), of a few tens to hundreds of parsec across, are a common and yet poorly studied feature of early-type galaxies. Still, such small discs represent a powerful tool to constrain the assembling ...

      An improved high-resolution and deep A Ks foreground dust extinction map is presented for the Galactic disc area within 295◦ ≾ l ≾ 350◦, −1.0◦ ≾ b ≾ +1.0◦. At some longitudes the map reaches up to |b| ~ 2.25◦, for a total ...

    • The Fornax3D project: Planetary nebulae catalogue and independent distance measurements to Fornax cluster galaxies 

      Spriggs, T. W.; Sarz, M.; Anta, P. M. Galán-de; Napiwotzki, R.; Viaene, S.; Nedelchev, B.; Coccato, L.; Corsini, E. M.; Fahrion, K.; Falcón-Barroso, J.; Gadotti, D. A.; Iodice, E.; Lyubenova, M.; Martín-Navarro, I.; McDermid, R. M.; Morelli, L.; Pinna, F.; Ven, G. van de; Zeeuw, P. T. de; Zhu, L. (2021-09-29)
      Extragalactic planetary nebulae (PNe) offer a way to determine the distance to their host galaxies thanks to the nearly universal shape of the planetary nebulae luminosity function (PNLF). Accurate PNe distance measurements ...

    • Multiband photometric decomposition of nuclear stellar disks 

      Morelli, L.; Cesetti, M.; Corsini, E.M.; Pizzella, A.; Dalla Bonta, E.; Sarzi, M.; Bertola, F. (2010)
      Context. Small, bright stellar disks with scale lengths of a few tens of parsec are known to reside in the center of galaxies. They are believed to have formed in a dissipational process as the end result of star formation ...

    • Nuclear discs as clocks for the assembly history of early-type galaxies: the case of NGC 4458 

      Sarzi, M.; Ledo, H.~R.; Coccato, L.; Corsini, E.~M.; Dotti, M.; Khochfar, S.; Maraston, C.; Morelli, L.; Pizzella, A. (2016-04-01)
      Approximately 20 per cent of early-type galaxies host small nuclear stellar discs that are tens to a few hundred parsecs in size. Such discs are expected to be easily disrupted during major galactic encounters, hence their ...

    • Stellar Populations of Bulges in 14 Cluster Disc Galaxies 

      Morelli, L.; Pompei, E.; Pizzella, A.; Mendez-Abreu, J.; Corsini, E.M.; Coccato, L.; Saglia, R.P.; Sarzi, M.; Bertola, F. (2008)

    • Structure and dynamics of galaxies with a low surface brightness disc. I. The stellar and ionised-gas kinematics
