The ESPRESSO Redshift Drift Experiment III -- The Third Epoch of QSO J052915.80-435152.0

Andrea Trost, Catarina M. J. Marques, S. Cristiani +25

The Sandage-Loeb test probes cosmic expansion directly by measuring the redshift drift in quasar absorption features in a model-independent way. In this series of papers, we have l…

The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection

Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12

The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$α…

The ESPRESSO Redshift Drift Experiment I -- High-resolution spectra of the Lyman- forest of QSO J052915.80-435152.0

Andrea Trost, Catarina M. J. Marques, Stefano Cristiani +25

The measurement of the temporal evolution in the redshift of distant objects, the redshift drift, is a probe of universal expansion and cosmology. We perform the first steps toward…

Probing the small scale structure of the Inter-Galactic Medium with ESPRESSO: spectroscopy of the lensed QSO UM673

Stefano Cristiani, Guido Cupani, Andrea Trost +20

The gravitationally lensed quasar J014516.6-094517 at z=2.719 has been observed with the ESPRESSO instrument at the ESO VLT to obtain high-fidelity spectra of the two images A and…

Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414

Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40

The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…
