    The 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...

    Ram-pressure feeding of supermassive black holes

    The majority of ‘jellyfish’ galaxies, characterized by long ‘tentacles’ of gas, also have active nuclei, indicating that gas is being fed to the central supermassive black hole by ram pressure.

    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 ...

    Multiwavelength Study of the NEPR Sample. The 60 μm Luminosity Function

    We present the 60 μm luminosity function (LF) of the deepest complete IRAS selected sample [1] so far available, in the North Ecliptic Polar Region (NEPR). The LF here is the first step in the multi-wavelength st...

    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 ...

    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...
