Harassment Origin for Kinematic Substructures in Dwarf Elliptical Galaxies?
A. C. Gonzalez-Garcia, J. A. L. Aguerri, M. Balcells
We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum and shows counter-r…
Structural Parameters of Dwarf Galaxies in the Coma Cluster: On the Origin of dS0 Galaxies
J. A. L. Aguerri, J. Iglesias-Páramo, J. M. Vilchez +2
In this paper we analyze the structural parameters of the dwarf galaxies in the Coma cluster with and classify them in two types: those with surface brightn…
The line-of-sight velocity distributions of intracluster planetary nebulae in the Virgo cluster core
Magda Arnaboldi, Ortwin Gerhard, J. Alfonso L. Aguerri +4
Radial velocities of 40 intracluster planetary nebulae (ICPNe) in the Virgo cluster were obtained with the new multi-fiber FLAMES spectrograph on UT2 at VLT. For the first time, th…
Intracluster stars in the Virgo cluster core
J. A. L. Aguerri, O. E. Gerhard, M. Arnaboldi +3
We have investigated the properties of the diffuse light in the Virgo cluster core region, based on the detection of intracluster planetary nebulae (PNe) in four fields. We elimina…
Satellite Infall and the Growth of Bulges of Spiral Galaxies
M. C. Eliche-Moral, M. Balcells, J. A. L. Aguerri +1
For bulges of spiral galaxies, the concentration, or Sersic index, increases with bulge luminosity and bulge-to-disk ratio B/D (Andredakis, Peletier, & Balcells 1995, MNRAS, 275, 8…
Photometric properties and origin of bulges in SB0 galaxies
J. A. L. Aguerri, N. Elias-Rosa, E. M. Corsini +1
We have derived the photometric parameters for the structural components of a sample of fourteen SB0 galaxies by applying a parametric photometric decomposition to their observed $…
