We present the star formation history (SFH) of the Sculptor dwarf spheroidal galaxy based on deep g, r photometry taken with Dark Energy Camera at the Blanco...

We present the star formation history (SFH) of the Sextans dwarf spheroidal galaxy based on deep archive B, I photometry taken with Suprime-Cam at Subaru...

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...
