Multi-wavelength spectroscopic probes: biases from neglecting light-cone 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…
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…
Magnification and evolution biases in large-scale structure surveys
Roy Maartens, José Fonseca, Stefano Camera +3
Measurements of galaxy clustering in upcoming surveys such as those planned for the Euclid and Roman satellites, and the SKA Observatory, will be sensitive to distortions from lens…
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…
Anti-symmetric clustering signals in the observed power spectrum
José Fonseca, Chris Clarkson
In this paper, we study how to directly measure the effect of peculiar velocities in the observed angular power spectra. We do this by constructing a new anti-symmetric estimator o…
