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…

Single-dish HI Intensity Mapping with the SKAO: Precursor Progress with MeerKAT's Large Area Synoptic Survey (MeerKLASS)

Steven Cunnington, Jingying Wang, Mario G. Santos +16

Using the SKAO to map the intensity of neutral hydrogen's 21cm emission line will be a golden opportunity to constrain models of cosmology. To access the largest cosmological scale…

MeerKLASS L-band deep-field intensity maps: entering the HI dominated regime

MeerKLASS Collaboration, Matilde Barberi-Squarotti, José L. Bernal +18

We present results from MeerKAT single-dish HI intensity maps, the final observations to be performed in L-band in the MeerKAT Large Area Synoptic Survey (MeerKLASS) campaign. The…

Prospects for cosmic magnification measurements using HI intensity mapping

Amadeus Witzemann, Alkistis Pourtsidou, Mario G. Santos

We investigate the prospects of measuring the cosmic magnification effect by cross-correlating neutral hydrogen intensity mapping (HI IM) maps with background optical galaxies. We…

Simulated multi-tracer analyses with HI intensity mapping

Amadeus Witzemann, David Alonso, José Fonseca +1

We use full sky simulations, including the effects of foreground contamination and removal, to explore multi-tracer synergies between a SKA-like 21cm intensity mapping survey and a…

Future Cosmological Constraints from Fast Radio Bursts

Anthony Walters, Amanda Weltman, B. M. Gaensler +2

We consider the possible observation of Fast Radio Bursts (FRBs) with planned future radio telescopes, and investigate how well the dispersions and redshifts of these signals might…
