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…
Cleaning foregrounds from single-dish 21cm intensity maps with Kernel Principal Component Analysis
Melis O. Irfan, Philip Bull
The high dynamic range between contaminating foreground emission and the fluctuating 21cm brightness temperature field is one of the most problematic characteristics of 21cm intens…
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…
21cm foregrounds and polarization leakage: a user's guide on cleaning and mitigation strategies
Steven Cunnington, Melis O. Irfan, Isabella P. Carucci +2
The success of HI intensity mapping is largely dependent on how well 21cm foreground contamination can be controlled. In order to progress our understanding further, we present a r…
Recovery of 21 cm intensity maps with sparse component separation
Isabella P. Carucci, Melis O. Irfan, Jérôme Bobin
21 cm intensity mapping has emerged as a promising technique to map the large-scale structure of the Universe. However, the presence of foregrounds with amplitudes orders of magnit…
Determining thermal dust emission from Planck HFI data using a sparse, parametric technique
Melis O. Irfan, Jérôme Bobin, Marc-Antoine Miville-Deschênes +1
Context: The Planck data releases have provided the community with sub-millimetre and radio observations of the full-sky at unprecedented resolutions. We make use of the Planck 353…
