We report how the action of radiation forces on small solid particles in a circumstellar disk could induce a suitable mechanism for orbital migration of...

We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very...

Aims: The spatial structure of the emission lines and continuum over the 50″ extent of the nearby, O-rich, PN NGC 7009 (Saturn Nebula) have been observed with...

This paper presents the results of a high-resolution imaging survey, using both ground-based and Hubble Space Telescope images, of a complete sample of nearby...

The identification of high-redshift, massive galaxies with old stellar populations may pose challenges to some models of galaxy formation. However, to securely...

The implicit intergral method that we have already introduced in a previous paper, together with its application to the non-Local Thermal Equilibrium (non-LTE)...

In view of more general applications, we have developed a new approach to render explicit the temperature both in the source function of the radiative transfer...

In this paper we present a new method to solve those radiative transfer problems where the scattering term in the source function, i.e., the frequency...

In the previous papers of this series, we introduced the implicit integral method (IIM) to solve those radiative transfer (RT) problems in which the source...
