PublicationA bright triple transient that vanished within 50 min
We report on three optically bright, ~16th mag, point sources within 10 arcsec of each other that vanished within 1 h, based on two consecutive exposures at...

PublicationA deep WISE search for very late type objects and the discovery of two halo/thick-disc T dwarfs: WISE 0013+0634 and WISE 0833+0052
A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and...

PublicationA determination of the space density and birth rate of hydrogen-line (DA) white dwarfs in the Galactic plane, based on the UVEX survey
We present a determination of the average space density and birth rate of hydrogen-line (DA) white dwarfs within a radius of 1 kpc around the Sun, based on an...

PublicationA first catalogue of automatically selected ultraviolet-excess sources from the UVEX survey
We present the first catalogue of point-source ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the Northern Galactic Plane (UVEX). UVEX...

PublicationA K band survey in the Groth Strip Flanking Fields
As a part of our collaboration in the COSMOS Project, devoted to the characterization of galaxies during the epoch of maximum star formation in the history of...

PublicationA Ks-band-selected catalogue of objects in the ALHAMBRA survey
The original ALHAMBRA catalogue contained over 400 000 galaxies selected using a synthetic F814W image, to the magnitude limit AB(F814W) ≈ 24.5. Given the...

PublicationA Large-Area CCD Camera for the Schmidt Telescope at the Venezuelan National Astronomical Observatory
We have designed, constructed, and put into operation a large-area CCD camera that covers a large fraction of the image plane of the 1 m Schmidt telescope at...

PublicationA long-wavelength view on galaxy evolution from deep surveys by the Infrared Space Observatory
We discuss the constraints set on galaxy evolution by a variety of data from deep extragalactic surveys performed in the mid-IR and far-IR with the Infrared...
