Methodological Frontiers in 21-cm Intensity Mapping: the Treatment of Systematics and Foreground Contamination
Marta Spinelli, Matilde Barberi-Squarotti, José Luis Bernal +29
The distribution of neutral hydrogen (HI) in the post-reionization universe traces the cosmic large-scale structure and therefore serves as a powerful cosmological probe. An effici…
The SKA View of the Sunyaev-Zeldovich Effect from Massive Cosmic Halos
Yvette C. Perrott, Luca Di Mascolo, Rémi Adam +4
The thermal intracluster medium (ICM) can be observed via its interaction with Cosmic Microwave Background photons, known as the Sunyaev-Zeldovich (SZ) effect. This effect produces…
Fast Simultaneous Surveys with On-the-Fly Mapping
