Gravity is the key engine for the evolution of the universe and the formation of its main structures: galaxies, clusters of galaxies and filaments. Gravity is...

We present methods to (i) graphically identify robust redshifts using emission lines in the (sub)mm regime, (ii) evaluate the capabilities of different (sub)mm...

We analyse the stellar populations in the host galaxies of 53 X-ray selected optically dull active galactic nuclei (AGN) at 0.34 z 1.07 with ultradeep (mAB =...

From a new mosaic image in the H-α line of the complete disc of the spiral galaxy M100, a catalogue is composed listing 1948 individual HII regions. For each...

From an H-α image of the spiral barred galaxy NGC 3359, an HII region catalogue is composed. The catalogue comprises the position, mean radius and the...

HII region catalogue of the barred galaxy NGC 7479. The catalogue contains the position, mean radius and the calibrated H-alpha luminosity of each HII region...

Complete list of the 376 photometrically calibrated individual HII regions in the spiral galaxy NGC 628. (1 data file).

Several authors have claimed that less luminous active galactic nuclei (AGNs) are not capable of sustaining a dusty torus structure. Thus, a gradual resizing of...

Theory predicts that cosmological gas accretion plays a fundamental role fuelling star formation in galaxies. However, a detailed description of the accretion...
