The observations were made on 2003 March 29, 30 and 31 with UVES, at the VLT Kueyen Telescope in Cerro Paranal Observatory (Chile). We used the standard...

We present first results from the analysis of a sample of 14 planetary nebulae with [WC] nucleus with detected faint carbon and oxygen recombination lines (RLs)...

We have digitally coadded APM scans of 13 Kodak TechPan films of the SE region of the Virgo Cluster of galaxies. The ~6.2°×6.2° field of the R-band films...

We report on the preparation of a catalog of faint polarizedstandards for near infrared bands. The catalog will onlycontain faint targets (below J ≃ 14) which...

In this paper we propose a method to classify faint objects from digital astronomical images based on multilayer feed-forward neural networks which have been...

The RXTE All-Sky monitor shows new detections of the black hole binary, XTE J1118+480, reported to be in optical outburst (ATEL #383). The source is first seen...
