Connecting CGM enrichment with Lyman alpha emitters at 2.9 < z < 6.7
A. M. Sebastian, E. Ryan-Weber, R. L. Davies +2
We present the results of a blind search for Lyman emitters (LAEs) in three deep archival quasar fields from VLT/MUSE using state-of-the-art detection algorithms. We…

The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field
Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +19
We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…

A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…
