Radio Recombination Line Contamination in Post-Reionization 21 cm Intensity Mapping
Pip Petersen, Yakov Faerman, Matthew McQuinn
The paper evaluates how radio recombination lines (RRLs) could contaminate post‑reionization 21 cm intensity‑mapping measurements, develops a formalism to predict their impact on t…

Cosmic topology. Part I. Limits on orientable Euclidean manifolds from circle searches
Pip Petersen, Yashar Akrami, Craig J. Copi +9
The Einstein field equations of general relativity constrain the local curvature at every point in spacetime, but say nothing about the global topology of the Universe. Cosmic micr…
