Open AccessThe IAU recommended photometric system for ultraviolet astronomy
In the current era when access to space is becoming easier and at a lower cost thanks to the standardised cubesat technology, numerous missions are expected to be launched to observe, particularly, at ultravio...

The Impact of Encounters on the Members of Local Group Analogs. A View from GALEX
The bright galaxy population of the Local Group Analog (LGA) LGG 225 has been imaged with the Galaxy Evolution Explorer (GALEX) through its Far- and Near-UV wavebands. A significant fraction of the group members ...

The Fundamental Plane of Radio Galaxies
The global properties of early-type galaxies are fairly well described through a linear relation (the Fundamental Plane, FP [2],[3]) in the space defined by three observables: the effective radius r ...

Isolated and Mildly Interacting Spiral Galaxies: Rotation Curves and Metallicities
We present the study of long slit spectra in the region of Hα emission line of a sample of 111 spiral galaxies with recognizable and well defined spiral morphology and with a well determined environmental stat...

Evolution of Galaxy morphologies in Clusters
We have studied the evolution of galaxian morphologies from ground-based, good-seeing images of 9 clusters at z=0.09-0.25. The comparison of our data with those relative to higher redshift clusters(Dressler et al...

The Kormendy Relation for 3 Abell Clusters
As part of our ongoing study of the Fundamental Plane (FP) for cluster ellipticals we present here the Kormendy relation for the Abell clusters A1878 (z=0.254), A2111 (z=O.229) and A2151 (z=O.037). We apply ou...

NGC 4546, the Double-Spin SB0
NGC 4546 is a barred S0 seen almost edge-on whose stellar disc is cut on the equatorial plane by a disc of gas rotating in the opposite direction and with relative circular velocities as great as 400 km sec−1. Du...
