TL;DR: In this paper, the authors used high-quality, medium-resolution Hubble Space Telescope/Cosmic Origins Spectrograph (HST/COS) observations of 82 UV-bright active galactic nuclei (AGNs) at redshifts z(AGN) \textless 0.85 to construct the largest survey of the low-redshift intergalactic medium (IGM) to date: 5138 individual extragalactic absorption lines in H I and 25 different metal-ion species grouped into 2611 distinct redshift systems at z(abs) = 21.

SSUSI-lite: next generation far-ultraviolet sensor for characterizing geospace
Larry J. Paxton,John E. Hicks,M. P. Grey,Charles Parker,Ramsay S. Hourani,Kathryn M. Marcotte,Uno P. Carlsson,Samuel Kerem,S. Osterman,Bryan J. Maas,Bernard S. Ogorzalek +10 more
- 21 Oct 2016
TL;DR: SSUSI-Lite as mentioned in this paper is an update of an existing sensor, SSUSI, which is designed to provide space weather information such as: auroral imagery, ionospheric electron density profiles, and neutral density composition changes.

SSUSI-Lite: a far-ultraviolet hyper-spectral imager for space weather remote sensing
Bernard S. Ogorzalek,S. Osterman,Uno P. Carlsson,M. P. Grey,John C. Hicks,Ramsey Hourani,Samuel Kerem,Kathryn M. Marcotte,Charles Parker,Larry J. Paxton +9 more
TL;DR: SSUSI-Lite contains an improved scanner design that results in precise mirror pointing and allows for variable scan profiles and the largest decrease in volume, mass, and power has been obtained by consolidating all control and power electronics into one data processing unit.
