We present the characterization of additional properties of the night-sky at the Calar Alto observatory, following the study started in Sánchez et al. (2007), hereafter Paper I. We focus here on the night sky-brightness at the near-infrared, the telescope seeing, and the fraction of useful time at the observatory. For this study we have collected a large dataset comprising 7311 near-infrared im...

Dual-band negative-index metamaterial designs in the near-infrared frequency range are presented and their performance is analyzed using a full-wave numerical electromagnetic scattering method. Negative effective permittivity is provided by a thin layer of metallic film. Negative effective permeabilities are supplied in two distinct frequency bands by magnetic resonators of different dimensions...

We present the results of an extensive infrared study of the massive star– forming region G9.62+0.19. The data cover information from broad– and narrow–band filters in the wavelength range from 1 to 19 μm and are obtained with ESO’s near– and thermal infrared camera ISAAC at the VLT and with the mid–infrared cameras TIMMI2 (La Silla, ESO) and SpectroCam-10 (Mt. Palomar). The high sensitivity an...

We present results from a near-infrared K-band imaging survey of 59 elliptical galaxies in ve nearby clusters. We measure photometric parameters for each galaxy using surface photometry and draw velocity dispersions from the literature. Three observables deene a near-infrared Fundamental Plane (FP) of elliptical galaxies with e. The scatter in the near-infrared relation is small at 16:5% in dis...

Optical and near-infrared observations of the GRB990705 error box were carried out with ESO telescopes at La Silla and Paranal in Chile and with the NOAO SPIREX 0.6-meter telescope in Antarctica. We detected the counterpart of this GRB in the near-infrared H band and optical V band. The power-law decline of the near-infrared lightcurve is rather steep with a decay index α ≃ 1.7 in the first hou...

A heterojunction between crystalline silicon and colloidal quantum dots (CQDs) is realized. A special interface modification is developed to overcome an inherent energetic band mismatch between the two semiconductors, and realize the efficient collection of infrared photocarriers generated in the CQD film. This junction is used to produce a sensitive near infrared photodetector.
