We present our on-going project to unveil the post-nova population by re-discovering old novae that have been lost after the initial outburst and in which the...
The Potential of Integral Field Spectroscopy Observing Extrasolar Planet Transits
We explore the use of Integral Field Spectroscopy (IFS) for observing extrasolar planet transits. We show that IFS can improve the photometric accuracy in high...
The Pre-flight Calibration of the ISOPHOT Instrument
Extensive characterisation of subsystems such as detectors and their curing, preamplifiers, filters, on-board secondary standard sources and cryomechanisms were...
HARMONI is a visible and near-infrared (0.47 to 2.45 μm) integral field spectrograph, providing the ELT's core spectroscopic capability at first light. A pre...
The Precipitable Water Vapour GNSS monitors at the Canary Islands Astronomical Observatories: towards an optimization of the final accuracy
Since proposed by Bevis et al. in 1992, GNSS Meteorology has become a very competitive field, mainly because it provides a relatively cheap, extensive network...
The preliminary design of the M1 assembly for the European Solar Telescope
The European Solar Telescope (EST) is a 4-meter class solar telescope led by the Instituto Astrofísico de Canarias that will be erected in La Palma Island. The...
The Preparation of the GTC for the Scientific Operation of CanariCam
CanariCam is a mid-IR camera and spectrograph with coronographic and polarimetric capabilities, built by the University of Florida to operate at the GTC...
The prevalence of neutral gas in massive post-main-sequence nebulae
Results are reported from a CO (J = 2-1) survey of nine type I nebulae using the 12-m NRAO antenna at KPNO; the data are presented in tables, graphs, and...
