Infrared fibres in astronomical instrumentation [PDF]

, 1995
For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

Development of a Monitoring System for an Infrared Camera [PDF]

Journal of Astronomy and Space Sciences, 2006
The KASINICS (KASI Near-Infrared Camera System) is a ground-based instrument developed by the Korea Astronomy and Space Science Institute (KASI). We developed a temperature and vacuum monitoring system for operating the KASINICS.

Detecting the near-infrared afterglows of high-redshift gamma-ray bursts using CAGIRE [PDF]

Astronomy & Astrophysics
Transient sky astronomy is entering a new era with the advent of the Space Variable Objects Monitor mission (SVOM), successfully launched on 22 June 2024. The primary goal of SVOM is to monitor the hard X-ray sky searching for gamma-ray bursts (GRBs). On

Hydration Features on Near-Earth Objects: Integrating New Data with Prior Results

The Planetary Science Journal
Near-Earth objects (NEOs) are excellent laboratories for testing processes that affect airless bodies, as well as informing us about solar system history. Though most NEOs are nominally anhydrous because they formed inside the solar system frost line and
