Quasars are the most luminous stable sources in the Universe. They are currently
observed out to redshift z ~ 7 when the Universe was less than one tenth of its
present age. Since their discovery 50 years ago astronomers have dreamed of using

The origin of the main excitation mechanisms in LINER 
(Low Ionization Emission Line Region) nuclei are
still controversial, with nonstellar photoionization,

We have developed a reliable powerful method to measure the atmospheric column of
water vapour (PWV) down to very low levels.
For this purpose we use and off-the-shelf cheap spectrometer to measure the
equivalent width of the H2O bands at 940nm.

In this talk we will perform a review of the basic principles of the optical/near-infrared interferometry and of the current European facilities to use this observational technique. Particularly, we will describe the interferometric observables used at near-infrared wavelengths.

Outflows generated by protostars heavily affect the kinematics
and chemistry of the hosting molecular cloud due to strong shocks. These
shocks heat and compress the ambient dense gas switching on a complex
chemistry that leads to an enhancement of the abundance of several

Planetary nebulae (PN) are one of the final phases in the evolution of
low and intermediate mass stars (<8 Msun). They display a great variety
of shapes, although in their previous phases (Asymptotic giant branch

In this talk -my last one in the IAA for the moment- I will talk

The European VLBI Network (EVN) is currently the most sensitive VLBI array in the world (its collecting area is about a hundred thousand square meters, or 1/10 of the planned Square Kilometer Array). 

The science performed in Astronomy is digital science, from observing proposals to final publication, including data and software used: each of the elements and actions involved in the scientific output could be recorded in electronic form.

SN1993J, a powerful radio supernova high in the northern sky, has been monitored with VLBI though its lifetime. The VLBI observations have been phase-referenced to the core of M81.
