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…
Observing relativistic features in large-scale structure surveys -- II: Doppler magnification in an ensemble of relativistic simulations
Louis Coates, Julian Adamek, Philip Bull +2
The standard cosmological model is inherently relativistic, and yet a wide range of cosmological observations can be predicted accurately from essentially Newtonian theory. This is…
Observing relativistic features in large-scale structure surveys -- I: Multipoles of the power spectrum
Caroline Guandalin, Julian Adamek, Philip Bull +3
Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation, and…
Searching for dark energy in the matter-dominated era
Philip Bull, Martin White, Anže Slosar
Most efforts to detect signatures of dynamical dark energy are focused on late times, , where the dark energy component begins to dominate the cosmic energy density.…
DAYENU: A Simple Filter of Smooth Foregrounds for Intensity Mapping Power Spectra
Aaron Ewall-Wice, Nicholas Kern, Joshua S. Dillon +14
We introduce DAYENU, a linear, spectral filter for HI intensity mapping that achieves the desirable foreground mitigation and error minimization properties of inverse co-variance w…
Redundant-Baseline Calibration of the Hydrogen Epoch of Reionization Array
Joshua S. Dillon, Max Lee, Zaki S. Ali +76
In 21 cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally-smooth astrophysical foregrounds. The Hydrogen Epo…
