Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

RX J1211+2242 is an optically faint (B ≃ 19.2 mag) but X-ray bright (f2 - 10 keV = 5 × 10-12 erg cm-2 s-1) AGN, which has been shown to be a BL Lac object at...

The Gamow Explorer will use Gamma Ray Bursts (GRBs) to: 1) probe the high redshift universe (z < 6) when the first stars were born, galaxies formed and Hydrogen...

As part of the GTC Control System (GCS) a data processing package is being developed. We will describe the perfomance of the Data Processing Kit (DPK), using...

The standard Non-LTE problem consists in calculating the atomic level populations that are consistent with the intensity of the radiation field generated within...

The GEO 600 gravitational wave detector uses advanced technologies including signal recycling and monolithic fused-silica suspensions to achieve a sensitivity...

Originally thought to explore the high redshift Universe, the extreme depth of the Frontier Fields survey provides also an excellent opportunity to explore with...

This paper presents the results of the authors' study on the giant (radius = 60 pc) extragalactic H II region Hubble III in NGC 6822. Based on the observational...
