The first generation of E-ELT instruments will include an optic-infrared High Resolution Spectrograph, conventionally indicated as EELT-HIRES, which will be capable of providing unique breakthroughs… Continue Reading
APEX, the Atacama Pathfinder Experiment, has been successfully commissioned and is in operation now. This novel submillimeter telescope is located at 5107 m altitude on Llano de Chajnantor in the… Continue Reading
The ESO's VISIR instrument at Paranal is dedicated to observations in two mid-infrared (MIR) atmospheric windows: N-band (8-13 micron) and Q-band (16.5-24.5 micron). It is equipped with two DRS… Continue Reading
We present PUCHEROS, the high-resolution echelle spectrograph, developed at the Center of Astro-Engineering of Pontificia Universidad Catolica de Chile to provide an effective tool for research and… Continue Reading
VISIR – ESO’s VLT Imager and Spectrometer for mid-InfraRed – is a combined imager and echelle spectrograph, providing access to the atmospheric N and Q-band windows (7.7–13.3 and 16–24 μm) with a… Continue Reading
Many detectors, optical CCDs and IR arrays, are currently in operation onboard ESO instruments at the La Silla Paranal Observatory. A unified scheme for optical detector characterization has been… Continue Reading
The Department of Astronomy and Astrophysics (DAA) of the Pontificia Universidad Católica de Chile (PUC) operates a small observatory at Santa Martina hills located in the outskirts of Santiago.… Continue Reading
The ESO Paranal observatory is operating a heterogeneous set of science detectors. The maintenance and quality control of science detectors is an important routine task to retain the technical and… Continue Reading
Resumen en: This work presents an astroclimatologic analysis of the UC Santa Martina Observatory site. This site is located near Santiago at latitude 33.3°S, longitu...
This work presents the use of system modeling with the aim of maintaining and improving instrument performances. The complexity and cryogenic nature of infrared systems prevent continuous hardware… Continue Reading
