We examine the far-infrared (FIR) properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νL ν, 2500(erg s -1)]...
The star formation timescale of elliptical galaxies. Fitting [Mg/Fe] and total metallicity simultaneously
The alpha element to iron peak element ratio, for example [Mg/Fe], is a commonly applied indicator of the galaxy star formation timescale (SFT) since the two...
The star-formation rates of 1.5 < z < 2.5 massive galaxies
The star formation rate (SFR) is a key parameter in the study of galaxy evolution. The accuracy of SFR measurements at z ~ 2 has been questioned following a...
We present ISOCAM and ISOPHOT observations of the galaxy pair NGC 6090. The SED derived from all ISO measurements is typical for strong starbursts which were...
The starburst galaxy NGC 6090: from 2.5μm to 200μm.
We have carried out broad band photometry of the interacting galaxy system NGC 6090 from 3.6 to 200μm using ISOPHOT. This is complemented by a low resolution...
The Starburst-Active Galactic Nucleus Connection in Active Galaxies: The MassiveNuclear Star-Forming Disk in NGC 4303
Two-dimensional spectroscopy of the low-redshift active galaxy NGC 4303 obtained with the Two-Dimensional Fiber ISIS System is presented. The ionization...
The starburst-active galactic nucleus connection in the merger galaxy Mrk 938: an infrared and X-ray view
Mrk 938 is a luminous infrared (IR) galaxy in the local Universe believed to be the remnant of a galaxy merger. It shows a Seyfert 2 nucleus and intense star...
The statistics of voids as a tool to constrain cosmological parameters: σ8 and Γ
We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...
This paper presents observations made at intermediate spectral and spatial resolutions along the major and minor axes of the starburst galaxy NGC 253. The...
