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…

Unveiling Dark Matter free-streaming at the smallest scales with high redshift Lyman-alpha forest

Vid Iršič, Matteo Viel, Martin G. Haehnelt +8

This study introduces novel constraints on the free-streaming of thermal relic warm dark matter (WDM) from Lyman- forest flux power spectra. Our analysis utilises a high-resolut…

The relationship between IGM Lyman-alpha opacity and galaxy density near the end of reionization

Holly M. Christenson, George D. Becker, Anson D'Aloisio +6

Observed scatter in the Lyman-alpha opacity of quasar sightlines at has motivated measurements of the correlation between Ly opacity and galaxy density, as models that pre…

Constraints on the End of Reionization from the Density Fields Surrounding Two Highly Opaque Quasar Sightlines

Holly M. Christenson, George D. Becker, Steven R. Furlanetto +5

The observed large-scale scatter in Lyman opacity of the intergalactic medium at implies large fluctuations in the neutral hydrogen fraction that are unexpected long afte…

Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra

Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13

We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…

The Evolution of O I over 3.2 < z < 6.5: Reionization of the Circumgalactic Medium

George D. Becker, Max Pettini, Marc Rafelski +11

We present a survey for metal absorption systems traced by neutral oxygen over . Our survey uses Keck/ESI and VLT/X-Shooter spectra of 199 QSOs with redshifts up to…
