Towards constraining cosmology with HI--galaxy cross-correlations from MeerKLASS

We present an inference of cosmological parameters from the cross-correlation power spectrum between the MeerKLASS 2019 L-band HI intensity maps and the overlapping WiggleZ galaxies at $z \simeq 0.43$. The analysis is intended as a proof of concept to verify that the full pipeline, from the foreground cleaning of the m...

Cosmological Inference with Gravitational-Wave Dark Sirens and 21-cm Intensity Mapping: Forecasts for LIGO-Virgo-KAGRA with MeerKAT and SKAO

Gravitational waves (GWs) and 21-cm intensity mapping (IM) are emerging as complementary cosmological probes: GWs provide direct luminosity-distance measurements, while neutral-hydrogen (HI) IM traces the matter distribution in redshift space. Their synergy offers a promising avenue for precise measurements of the Hubb...

Detecting redshift space distortions with forthcoming 21cm intensity maps from MeerKLASS

Redshift space distortions (RSD) provide a powerful measurement of structure formation in modern cosmology. In this work, we explore the potential of 21cm intensity mapping with the MeerKAT Large Area Synoptic Survey (MeerKLASS) to detect RSD and probe gravity within the redshift range of MeerKAT's UHF band ($0.4<z<1.4...
