Exciting concepts are under development for flagship, probe class, explorer class, and
suborbital class NASA missions in the ultraviolet/optical spectral range. These missions will …

We simulate the flux emitted from galaxy haloes in order to quantify the brightness of the
circumgalactic medium (CGM). We use dedicated zoom-in cosmological simulations with the …

The circumgalactic medium (CGM) is one of the remaining least constrained components of
galaxies and as such has significant potential for advancing galaxy formation theories. In …

Abstract The Faint Intergalactic Medium Redshifted Emission Balloon (FIREBall) is a mission
designed to observe faint emission from the circumgalactic medium of moderate-redshift …

We present here the current state of a collection of promising ultraviolet technologies in
preparation for the Habitable Worlds Observatory. Working with experts representing a …

Commercially available UV fibers suffer from high absorption and solarization in the far-UV
range at λ< 200 nm. Recently, new hollow-core anti-resonant fiber optics (UV-HCFs) have …

We present the status of on-going detector development efforts for our joint NASA/Centre
National d'Études Spatiales balloon-borne UV multiobject spectrograph, the Faint …

The Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2) is an experiment
designed to observe low density emission from HI, CIV, and OVI in the circum-galactic …

We present an overview of the detector for the upcoming Faint Intergalactic Red-shifted
Emission Balloon (FIREBall-2) experiment, with a particular focus on the development of …

We present the latest developments in our joint NASA/CNES suborbital project. This project
is a balloon-borne UV multi-object spectrograph, which has been designed to detect faint …
