We present deep IJHK_s and H_2 images of a region in the Chamaeleon I dark cloud containing the very low-mass young object [KG2001]102, in an attempt to search for multiplicity and molecular outflows in the vicinity of this object. No low-velocity shocked structures were detected on our H_2 image. The broad-band and narrow-band images show that

Beamswitch experiments located at Teide Observatory, Tenerife operate at 10, 15, 33 GHz. An area of ˜1 steradian has been covered at angular scales from 5 to 20 degrees ( l=10-30 ) . Sensitivity is ˜10 μ K per beam area at 15 and 33 GHz and 26 μ K at 10 GHz which gives a measure of the CMB fluctuation amplitude to 10 %. These data have been used to

There is a long tradition on teaching Astronomy at the UCM University. Since 1972 it is possible to study Astrophysics at the Faculty of Physics of the UCM. The facilities of the UCM Observatory are improving continuously every year. Nowadays two domes (4 m) are available. The west dome is mainly used for doing solar observations while the east

A catalogue of galaxies with extremely red colours (R-J≥5), covering 8.43 square degrees has been selected from optical and near-infrared data. Based on their bright near-infrared magnitude and their very red colour, these objects are likely to be very massive galaxies with little or no ongoing star formation. We have derived a surface density of 0
