Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders

Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21

The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…

Searching for axion dark matter gegenschein of the Vela supernova remnant with FAST

Wenxiu Yang, Yitian Sun, Yougang Wang +7

Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a co…

The 21-cm forest as a simultaneous probe of dark matter and cosmic heating history

Yue Shao, Yidong Xu, Yougang Wang +4

The absorption features in spectra of high-redshift background radio sources, caused by hyperfine structure lines of hydrogen atoms in the intervening structures, are known collect…
