We present some results from a new 2D spectrograph, SAURON (Bacon et al. 2001; de Zeeuw et al. 2002). Each SAURON, exposure provides stellar as well as gaseous...

The theory of radiatively driven winds successfully explains the key points of the stellar winds of hot massive stars. However, there is an apparent break-down...

Over the last few years a large set of spectropolarimetric observations of prominences and spicules in the He I D3 multiplet have been collected at the...

New observations of the edge-on galaxy NGC 891, at 1.15 and 2mm obtained with the IRAM 30-m telescope and the NIKA2 camera, within the framework of the IMEGIN...

Primitive asteroids (PAs) are characterized by dark surfaces (albedo < 10%) dominated by carbon compounds. Their reflectance spectra are similar to those of...

Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major...

The Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of the Sloan Digital Sky Survey III, is exploring the stellar populations of the Milky...

Recent studies of the substellar population in the Taurus cloud have revealed a deficit of substellar objects by a factor ≃ 2 compared to the Trapezium cluster...
