Post-inflationary axion constraints from the Lyman- forest
Olga Garcia-Gallego, Vid IrÅ¡iÄ, Matteo Viel +2
Among the most compelling cold dark matter candidates, the axion has recently been subject to a wide range of astrophysical studies aiming to constraints its properties. We present…
Probing General Relativity on Cosmological Scales in the 2040s
Federico Montano, Samantha J. Rossiter, Chris Addis +18
General relativity is exquisitely tested in strong-field regimes, yet its validity on cosmological scales remains largely unexplored. Upcoming wide and deep large-scale structure s…
From the Intergalactic to the Interstellar Scales -- EQUALS: a High-resolution Legacy Survey of Gas in the Distant Universe Using ESPRESSO
Trystyn Berg, Valentina D'Odorico, Elisa Boera +14
Understanding how the Universe evolved from diffuse primordial gas into the rich cosmic web we observe today is one of the great challenges of modern astrophysics. Quasar absorptio…
Constraints on the Thompson optical depth to the CMB from the Lyman- forest
Olga Garcia-Gallego, Vid IrÅ¡iÄ, Martin G. Haehnelt +1
We present the first constraints on the electron optical depth to reionization, , from the Lyman- forest alone for physically motivated reionization models tha…
Constraining Mixed Dark Matter models with high redshift Lyman-alpha forest data
Olga Garcia-Gallego, Vid IrÅ¡iÄ, Martin G. Haehnelt +2
This study sets new constraints on Cold+Warm Dark Matter (CWDM) models by leveraging the small-scale suppression of structure formation imprinted in the Lyman- forest. Using th…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
