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 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 fragile and rare isotope 6Li has a spallative origin. It is rapidly destroyed in solar-type stars while fully preserved in low-mass brown dwarfs and planets...

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 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...

Narowband H alpha imaging and long-slit optical and near-infrared spectroscopy are analyzed in a study of the starburst galaxy NGC 7714. The data indicate that...

The evolution of an SNR in a high-density medium has been studied using analytical and numerical hydrodynamic and photoionization models. The models show that...

In the starburst model for active galactic nuclei (AGN), the observed broad emission lines and their variability are generated by compact, strongly radiative...

Two-dimensional spectroscopy of the low-redshift active galaxy NGC 4303 obtained with the Two-Dimensional Fiber ISIS System is presented. The ionization...
