Context: The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still being debated. Aims: We aim to...
Internal dynamics of the massive cluster Abell 697: a multiwavelength analysis
Aims.We conduct an intensive study of the rich, X-ray luminous, and hot galaxy cluster Abell 697 (at z=0.282), likely containing a diffuse radio-emission, to...

Aims.We present a detailed dynamical analysis of the rich galaxy cluster A2744, containing a powerful diffuse radio halo.Methods.Our analysis is based on...
Internal dynamics of the radio halo cluster Abell 773: a multiwavelength analysis
Aims:To conduct an intensive study of the rich, X-ray luminous galaxy cluster Abell 773 at z = 0.22 containing a diffuse radio halo to determine its dynamical...
Internal dynamics of the radio-halo cluster A2219: A multi-wavelength analysis
We present the results of the dynamical analysis of the rich, hot, and X-ray very luminous galaxy cluster A2219, containing a powerful diffuse radio-halo. Our...
Internal kinematics and dynamical models of dwarf spheroidal galaxies around the Milky Way
We review our current understanding of the internal dynamical properties of the dwarf spheroidal galaxies surrounding the Milky Way. These are the most dark...
Internal kinematics of dwarf satellites of MW/M31-like galaxies in TNG50
We present a kinematic study of a thousand of dwarf satellites of MW/M31-like hosts from the IllustrisTNG50 simulation. Internal kinematics were derived for all...
We present measurements of internal proper motions at more than 500 positions of NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 on board the...
Internal reddening of H II-regions and HH-objects, with special reference to NGC 896 (W3)
The effect of scattering by dust internal to H II regions on their spectral characteristics has been studied on the basis of simple analytical models, for...
