Precision Cosmology with the Lightest Elements
Max Pettini, Ryan Cooke
This is a transcript of the joint talk we gave at the Sixth Gruber Cosmology Conference at Yale University on 3 October 2025. We describe the key role played by Big Bang Nucleosynt…
A search for HI 21cm absorption towards a radio-selected quasar sample II: a new low spin temperature DLA at high redshift
Nissim Kanekar, Sara L. Ellison, Emmanuel Momjian +2
We report results from a deep search for redshifted HI 21cm absorption from eight damped Lyman- absorbers (DLAs) detected in our earlier optical survey for DLAs towards radio-lo…
A downturn in intergalactic CIV as redshift 6 is approached
Emma V. Ryan-Weber, Max Pettini, Piero Madau +1
We present the results of the largest survey to date for intergalactic metals at redshifts z > 5, using near-IR spectra of nine QSOs with emission redshifts z(em) > 5.7. We find, f…
