HI intensity mapping with MeerKAT: power spectrum detection in cross-correlation with WiggleZ galaxies
Steven Cunnington, Yichao Li, Mario G. Santos +13
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a detection of the cross-corre…
Gaussian Process Regression for foreground removal in HI intensity mapping experiments
Paula S. Soares, Catherine A. Watkinson, Steven Cunnington +1
We apply for the first time Gaussian Process Regression (GPR) as a foreground removal technique in the context of single-dish, low redshift HI intensity mapping, and present an ope…
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…
Power spectrum multipole expansion for HI intensity mapping experiments: unbiased parameter estimation
Paula S. Soares, Steven Cunnington, Alkistis Pourtsidou +1
We assess the performance of the multipole expansion formalism in the case of single-dish HI intensity mapping, including instrumental and foreground removal effects. This formalis…
The cosmic abundance of cold gas in the local Universe
Thomas J. Fletcher, Amelie Saintonge, Paula S. Soares +1
We determine the cosmic abundance of molecular hydrogen (H2) in the local universe from the xCOLD GASS survey. To constrain the H2 mass function at low masses and correct for the e…
Multipole expansion for HI intensity mapping experiments: simulations and modelling
Steven Cunnington, Alkistis Pourtsidou, Paula S. Soares +2
We present a framework and an open-source python toolkit to analyse the 2-point statistics of 3D fluctuations in the context of HI intensity maps using the multipole expansion form…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
