Beyond ΛCDM with the SKA Observatory -- II: Unveiling the Secrets of the Early Universe
José Fonseca, Benedict Bahr-Kalus, Mario Ballardini +12
The origins of the universe remain one of the biggest mysteries in modern cosmology. While the Planck satellite has provided a wealth of information about the early universe, there…
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…
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…
Revealing cosmological fluctuations in 21cm intensity maps with MeerKLASS: from maps to power spectra
Steven Cunnington, Matilde Barberi-Squarotti, José Luis Bernal +8
Mapping the integrated 21cm emission line from dark matter-tracing neutral hydrogen gas is the primary science goal for MeerKLASS (MeerKAT's Large Area Synoptic Survey). Prior to t…
Emission-line Stacking of 21cm Intensity Maps with MeerKLASS: Inference Pipeline and Application to the L-band Deep-field Data
Zhaoting Chen, Steven Cunnington, Alkistis Pourtsidou +11
We present a novel analysis of observational systematics through the emission-line stacking of the MeerKLASS L-band deep-field intensity maps, following the detection in arXiv:2407…
Bispectrum constraints on Primordial non-Gaussianities with the eBOSS DR16 quasars
Marina S. Cagliari, Matilde Barberi-Squarotti, Kevin Pardede +2
We present constraints on , the parameter quantifying the amplitude of local Primordial Non-Gaussianities (PNG), from a combined analysis of the tree-level power spectr…
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…
Radio-optical synergies at high redshift to constrain primordial non-Gaussianity
Matilde Barberi Squarotti, Stefano Camera, Roy Maartens
We apply the multi-tracer technique to test the possibility of improved constraints on the amplitude of local primordial non-Gaussianity, , in the cosmic large-sca…
