Exploring quasar evolution with proximate molecular absorbers: Insights from the kinematics of highly ionized nitrogen
R. Cuellar, P. Noterdaeme, S. Balashev +3
We investigate the presence and kinematics of NV absorption proximate to high redshift quasars selected upon the presence of strong and HI absorption at the quasar redshift…
The Galaxy Counterparts of the two high-metallicity DLAs at z=2.412 and z=2.583 towards Q0918+1636
J. P. U. Fynbo, S. Geier, L. Christensen +9
The quasar Q0918+1636 (z=3.07) has two intervening high-metallicity Damped Lyman-alpha Absorbers (DLAs) along the line of sight, at redshifts of z=2.412 and 2.583. The z=2.583 DLA…
Deuterium at high-redshift: Primordial abundance in the zabs = 2.621 damped Ly-alpha system towards CTQ247
P. Noterdaeme, S. López, V. Dumont +3
The detection of neutral deuterium in the low-metallicity damped Lyman-α system at zabs = 2.621 towards the quasar CTQ247 is reported. Using a high signal-to-noise and high spectr…
CUBES: a UV spectrograph for the future
S. Covino, S. Cristiani, J. M. Alcala' +86
In spite of the advent of extremely large telescopes in the UV/optical/NIR range, the current generation of 8-10m facilities is likely to remain competitive at ground-UV wavelength…
A translucent interstellar cloud at z=2.69: CO, H2 and HD in the line-of-sight to SDSS J123714.60+064759.5
P. Noterdaeme, P. Petitjean, C. Ledoux +3
We present the analysis of a sub-DLA system (log N(H^0)=20.0+/-0.15, z_abs=2.69) toward SDSS J123714+064759 (z_em=2.78). Using the VLT/UVES and X-shooter spectrographs, we detect H…
CII*/CII ratio in high-redshift DLAs: ISM phase separation drives the observed bimodality of [CII] cooling rates
S. A. Balashev, K. N. Telikova, P. Noterdaeme
We discuss observations of CII*/CII ratios and cooling rates due to [CII]158m emission in high-redshift intervening damped Lyman- systems towards quasars. We show that…
