WST instrument Exposure Time Calculator: full simulation of multi-mode spectrograph performance from source to detector
Matteo Ferro, Matteo Genoni, Henri M. J. Boffin +13
We present a comprehensive Exposure Time Calculator (ETC) developed for the Wide-field Spectroscopic Telescope (WST) concept. The WST, currently in its conceptual phase, is designe…
Reaching the Metallicity Floor at : Lensed Star Clusters at Cosmic Dawn and Cosmic Noon
Raul Jimenez, Elena Tomasetti, Carmela Lardo +1
Origins of globular clusters (GCs) are linked to the assembly of their host galaxies. We analyze star-cluster populations in two strongly lensed systems that bracket Cosmic Dawn an…
Cosmic CORALS: Timing the Universe with high-z star clusters
Elena Tomasetti, Martin Millon, Licia Verde +5
In this work, we explore the potential of anchoring the age-redshift relation across cosmic time by probing the oldest star clusters at high redshift, now observed thanks to the Ja…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Chemo-dynamical reconstruction of Milky Way globular cluster progenitors: Age-metallicity relations and the universality of multiple stellar populations
Carmela Lardo, David Valcin, Raul Jimenez
Globular clusters encode the hierarchical assembly history of the Milky Way and the physics of multiple stellar populations. Using homogeneous stellar parameters for 69 Galactic gl…
The Age of the Universe with Globular Clusters IV: Multiple Stellar Populations
David Valcin, Raul Jimenez, Carmela Lardo +2
We revisit the determination of the age of the Universe from galactic globular clusters, extending previous analyses by explicitly accounting for the presence of multiple stellar p…
