The detection and number estimates of supermassive binary black holes (SMBBHs) provide important constraints on the hierarchical models for galaxy formation and...
Complex Organic Molecules in the Interstellar Medium
More than 200 species have been detected in the interstellar medium (ISM), among them many molecules, radicals and ions, containing the −C≡N functional group...
Deriving model-based chemical abundances in ionized gaseos nebulae
There is an increasing multiplicity of proposed methodologies to derive chemical abundances in HII regions from the measurement of the relative fluxes of their...
Dusty supernovae running the thermodynamics of the matter reinserted by young stellar clusters
Following the observational and theoretical evidence that points at core collapse supernovae as major producers of dust, we calculate the hydrodynamics of the...
Facing the Abundance Discrepancy in the Orion Nebula
The spectral analysis of HII regions allows one to determine the chemical composition of the ionized gas phase of the interstellar medium (ISM) from the solar...
Genuine spectral energy distribution of active galactic nuclei
Spectral energy distributions (SEDs) of the central few tens of parsec region of some of the nearest active galactic nuclei (AGN) are presented. Peering into...
We have selected the Galactic HII region M43, a close-by apparently spherical nebula ionized by a single star (HD37061, B0.5V) to investigate several topics of...
Magnetic field components analysis of the SCUPOL 850 microns polarization data catalog
I will present an extensive analysis of the 850 microns (353 GHz) polarization maps of the SCUBA Polarimeter Legacy (SCUPOL) Catalogue produced by Matthews et...
Nanocosmos : An experimental and observational approach to the study of dust formation in evolved stars
Evolved stars are factories of cosmic dust. This dust is made of tiny grains that are injected into the interstellar medium and plays a key role in the...
