AuroraMag: Twin Explorer of Asymmetry in Aurora and Solar Wind-Magnetosphere Coupling Open
In the present-day context, small satellites and their constellations consisting of varying sizes (nano, micro, pico satellites) are being favored for remote sensing and in situ probing of the heliosphere and terrestrial magnetosphere-iono…

Solar Occultation Experiments (SOE) in the Venusian Atmosphere: effect of orbital parameters on the spatiotemporal distribution of measurements Open
Solar occultation is a satellite-based technique for high-resolution vertical profiling of planetary atmospheres. Owing to the distinctive observational geometry, the deduction of the spatiotemporal coverage of solar occultation measuremen…

The MUSE <i>Hubble</i> Ultra Deep Field Survey Open
We investigated the ultraviolet (UV) spectral properties of faint Lyman- α emitters (LAEs) in the redshift range 2.9 ≤ z ≤ 4.6, and we provide material to prepare future observations of the faint Universe. We used data from the MUSE Hubble…

XV. The mean rest-UV spectra of Ly-alpha emitters at z>3 Open
We investigate the ultraviolet (UV) spectral properties of faint Lyman-$\alpha$ emitters (LAEs) in the redshift range 2.9 3. We compute various averaged spectra of LAEs sub-sampled on the basis of their observational (e.g., Ly$\alpha$ stre…

Solar-metallicity gas in the extended halo of a galaxy at <i>z</i> ∼ 0.12 Open
We present the detection and analysis of a weak low-ionization absorber at z = 0.121 22 along the sightline of the blazar PG 1424+240, using spectroscopic data from both HST/COS and STIS. The absorber is a weak Mg ii analogue, with an inci…

Detection of metal-rich, cool-warm gas in the outskirts of galaxy clusters Open
We present an ultraviolet quasar absorption line analysis of metal lines associated with three strong intervening H i absorbers (with $N(\rm {{H}\,{\small I}})$ > 1016.5 cm−2) detected in the outskirts of Sunyaev–Zel’dovich (SZ) effect-…
