Four direct measurements of the fine-structure constant 13 billion years ago

Michael R. Wilczynska, John K. Webb, Matthew Bainbridge +14

Observations of the redshift z=7.085 quasar J1120+0641 have been used to search for variations of the fine structure constant, alpha, over the redshift range 5.5 to 7.1. Observatio…

Studying the Lyman- $α$ optical depth fluctuations at $z \sim 5.5$ using fast semi-numerical methods

T. Roy Choudhury, Aseem Paranjape, Sarah E. I. Bosman

We present a computationally efficient and fast semi-numerical technique for simulating the Lyman- $α$ (Ly $α$ ) absorption optical depth in presence of neutral hydrogen "islands" lef…
