A z1 galactic-scale outflow transversally mapped to 50 kpc through gravitational-arc tomography
J. A. Hernández-Guajardo, L. F. Barrientos, S. López +12
We report spatially resolved measurements of cool gas traced by Mg II and Fe II absorption in the circumgalactic medium (CGM) of a star-forming galaxy at (G1). The fortuit…
One H2 molecule per ten million H-atoms reveals sub-pc scale cold overdensities at z~4
P. Noterdaeme, S. Balashev, T. Berg +11
We present the detection and analysis of H2 absorption at z = 4.24 towards the bright quasar J0007-5705, observed with the Very Large Telescope as part of the ESPRESSO QUasar Absor…
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…
Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon
Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen +7
The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons,…
