A. Sampath,Devin Crichton,Kavilan Moodley,H. C. Chiang,E. De,Lera Acedo,S. Dlamini,Sindhu Gaddam,Kit Gerodias,Quentin Gueuning,N. Gupta,Pascal Hitz,Aditya Krishna,Karigiri Madhusudhan,S. Krishna,V. Mugundhan,Edwin Retana-Montenegro,Benjamin Saliwanchik,Mario G. Santos,Anthony Walters +19 more
TL;DR: This study investigates the primary beam chromaticity of the HIRAX radio interferometric telescope, developing a physically motivated beam modeling technique to mitigate its impact on 21 cm power spectrum measurements and constrain cosmological parameters with high precision.
