Optical Counterparts of MeerKLASS L-band and UHF-band surveys
M. Klein, S. Mangla, J. Mohr +7
Context: Wide-area radio continuum surveys require reliable optical and infrared counterpart identification, but high optical source densities and extended or multi-component radio…
Cosmology with HI Intensity Mapping
Laura Wolz, Gabriele Autieri, José Luis Bernal +18
The redshifted spectral emission from neutral hydrogen (HI) at rest wavelength 21 cm can be used as a tracer of large-scale structure and its evolution. Within the HI intensity map…
meer21cm: an Analysis Pipeline and Comprehensive Toolkit for HI Intensity Mapping
Zhaoting Chen, Steven Cunnington, Daniel Tassie +23
We present meer21cm, a comprehensive python package for cosmological data analysis of single-dish HI intensity mapping surveys. This package is simple to use, with a modularised co…
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
Suman Chatterjee, Sarvesh Mangla, Sourabh Paul +10
The SKAO is a next-generation radio telescope that will transform our understanding of the formation and evolution of radio galaxies, quasars, transients, and other cosmic sources.…
