The pristine nature of SMSS 16051443 revealed by ESPRESSO
D. S. Aguado, E. Caffau, P. Molaro +20
SMSS J160540.18144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H]=-6.2, which was first reported with the SkyMapper tele…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
Photometric IGM Tomography: Efficiently Mapping Quasar Light Echoes with Deep Narrow Band Imaging
Koki Kakiichi, Tobias Schmidt, Joseph Hennawi
In the standard picture, episodes of luminous quasar activity are directly related to supermassive black hole (SMBH) growth. The ionising radiation emitted over a quasar's lifetime…
Fundamental physics with ESPRESSO: Constraints on Bekenstein and dark energy models from astrophysical and local probes
C. J. A. P. Martins, S. Cristiani, G. Cupani +21
Dynamical scalar fields in an effective four-dimensional field theory are naturally expected to couple to the rest of the theory's degrees of freedom, unless some new symmetry is p…
Chromatic Drift of the Espresso Fabry-Pérot Etalon
Tobias M. Schmidt, Bruno Chazelas, Christophe Lovis +5
In the last decade, white-light illuminated Fabry-Pérot interferometers wave been established as a widely used, relatively simple, reliable, and cost-effective way to precisely cal…
Fundamental Physics with ESPRESSO, Constraining a simple parametrisation for varying
Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes +24
The spectrograph ESPRESSO recently obtained a limit on the variation of the fine-structure constant, , through measurements along the line of sight of a bright quasar with a pre…
