We have obtained series of continuous differential photometry in the J and KS bands for several L-type dwarfs. We intend to search for photometric variability...

We present narrowband H-alpha imaging and long-slit optical and near-infrared spectroscopy of the giant H II region NGC 2363. The spectroscopic data are taken...

Near infrared monitoring taken with the 1.5 m Carlos Sanchez Telescope in Tenerife of the decline of 3C279 during its 1988 outburst is presented. These data are...

The paper reports partially simultaneous observations of the 'rapid burster' (MXB 1730-335) at X-ray, infrared, and radio wavelengths, covering several hundred...
