We have carried out a detailed CCD surface photometric analysis of the lenticular galaxy NGC 2907, containing multiple dust lanes, with the objective of studying properties of dust in an extragalactic environment. Measurements ...

We model the observed X-ray/radio knots in Active Galactic Nuclei (AGN) as isotropically expanding spherical plasma clouds fed continously by non-thermal electrons. The time-dependent electron distribution and the emitted ...

We describe in this paper the surface photometry of a set of lenticular galaxies. We then consider important correlations between morphological parameters of the bulges of lenticulars and other types of galaxies

In this paper we present some of the results of imaging observations of dusty ellipticals in the optical B & R bands as well as in near IR K'-band taken at the Las Campanas Observatory, Chile. We derive radial profiles of ...

Broad-band surface photometry in V, R and I colors is presented for three elliptical galaxies immersed in hot intracluster gas emitting X-rays due to thermal bremsstrahlung. The galaxies are (1) a cD galaxy, and (2) a radio ...
