Sharpening quasar absorption lines with ESPRESSO: Temperature of warm gas at , constraints on the Mg isotopic ratio, and structure of cold gas at
P. Noterdaeme, S. Balashev, C. Ledoux +7
We present a high-resolution (R=140,000) spectrum of the bright quasar HE0001-2340 (z=2.26), obtained with ESPRESSO at the Very Large Telescope. We analyse three systems at z=0.45,…
ESA Voyage 2050 white paper: A complete census of the gas phases in and around galaxies, far-UV spectropolarimetry as a prime tool for understanding galaxy evolution and star formation
V. Lebouteiller, C. Gry. H. Yan, P. Richter +18
(abridged) The far-UV wavelength range (912-2000A) provides access to atomic and molecular transitions of many species the interstellar medium (ISM), circumgalactic medium (CGM), a…
Far to near UV spectroscopy of the interstellar medium at very high resolution and very high signal-to-noise ratio
Cecile Gry, Edward B. Jenkins, Patrick Boissé +4
A comprehensive study of interstellar medium phases and the nature of their boundaries or connections requires comparing abundances and velocity profiles from tracers of the differ…
Dissecting cold gas in a high-redshift galaxy using a lensed background quasar
J. -K. Krogager, P. Noterdaeme, J. M. O'Meara +9
We present a study of cold gas absorption from a damped Lyman- absorber (DLA) at redshift towards two lensed images of the quasar J144254.78+405535.5 at reds…
