Multi-wavelength spectroscopic probes: prospects for primordial non-Gaussianity and relativistic effects
Jan-Albert Viljoen, José Fonseca, Roy Maartens
Next-generation cosmological surveys will observe larger cosmic volumes than ever before, enabling us to access information on the primordial Universe, as well as on relativistic e…
SKAO HI Intensity Mapping: Blind Foreground Subtraction Challenge
Marta Spinelli, Isabella P. Carucci, Steven Cunnington +5
Neutral Hydrogen Intensity Mapping (HI IM) surveys will be a powerful new probe of cosmology. However, strong astrophysical foregrounds contaminate the signal and their coupling wi…
HI intensity mapping with MeerKAT: Calibration pipeline for multi-dish autocorrelation observations
Jingying Wang, Mario G. Santos, Philip Bull +10
While most purpose-built 21cm intensity mapping experiments are close-packed interferometer arrays, general-purpose dish arrays should also be capable of measuring the cosmological…
Constraining the growth rate by combining multiple future surveys
Jan-Albert Viljoen, José Fonseca, Roy Maartens
The growth rate of large-scale structure provides a powerful consistency test of the standard cosmological model and a probe of possible deviations from general relativity. We use…
Non-Gaussianity Constraints using Future Radio Continuum Surveys and the Multi-Tracer Technique
Zahra Gomes, Stefano Camera, Matt J. Jarvis +2
Tighter constraints on measurements of primordial non-Gaussianity will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum-the standard…
Line intensity mapping: a "novel" window to the cosmic web
José Fonseca
Intensity mapping has been attracting increasing interest as a way to study galaxy evolution and the large scale structure of the Universe. Instead of detecting individual galaxies…
