Superconducting tunnel junctions as detectors for ultraviolet, optical, and near infrared astronomy [PDF]

Astronomy and Astrophysics Supplement Series, 1997
We discuss the capabilities of superconduct- ing tunnel junctions as detectors for ultraviolet, optical, and near-infrared astronomy. Such junctions have recently been shown to allow the detection of individual optical and ultraviolet photons with an inherent spectral resolu- tion related to the critical temperature of the absorbing superconductor ...

Recent developments in superconducting tunnel junctions for ultraviolet, optical & near infrared astronomy [PDF]

Astronomy and Astrophysics Supplement Series, 1998
Some recent results associated with the development of tantalum based photon counting superconducting tunnel junctions (STJ) suitable for use as broad-band low resolution spectrometers for optical and ultraviolet astronomy are presented. A m square tantalum based STJ, operated at a temperature of 0.3 K, has demonstrated a limiting resolution of  nm at ...

The Colorado Ultraviolet Transit Experiment Mission Overview

The Astronomical Journal, 2023
Atmospheric escape is a fundamental process that affects the structure, composition, and evolution of many planets. The signatures of escape are detectable on close-in, gaseous exoplanets orbiting bright stars, owing to the high levels of extreme ...

Constraints on Stellar Flare Energy Ratios in the NUV and Optical from a Multiwavelength Study of GALEX and Kepler Flare Stars

The Astrophysical Journal, 2023
We present a multiwavelength study of stellar flares on primarily G-type stars using overlapping time domain surveys in the near-ultraviolet (NUV) and optical regimes. The NUV (the Galaxy Evolution Explorer; GALEX) and optical (Kepler) wavelength domains
