Potential Impact of Global Navigation Satellite Services on Total Power HI Intensity Mapping Surveys
Stuart Harper, Clive Dickinson
Future total-power single-dish HI intensity mapping (HI IM) surveys have the potential to provide unprecedented insight into late time () cosmology that are competitive with…
The BINGO Project II: Instrument Description
Carlos A. Wuensche, Thyrso Villela, Elcio Abdalla +41
The measurement of diffuse 21-cm radiation from the hyperfine transition of neutral hydrogen (HI signal) in different redshifts is an important tool for modern cosmology. However,…
HI intensity mapping with MeerKAT: 1/f noise analysis
Yichao Li, Mario G. Santos, Keith Grainge +2
The nature of the time correlated noise component (the 1/f noise) of single dish radio telescopes is critical to the detectability of the HI signal in intensity mapping experiments…
Update on the BINGO 21cm intensity mapping experiment
Richard Battye, Ian Browne, Tianyue Chen +21
21cm intensity mapping is a novel approach aimed at measuring the power spectrum of density fluctuations and deducing cosmological information, notably from the Baryonic Acoustic O…
HI intensity mapping with FAST
Marie-Anne Bigot-Sazy, Yin-Zhe Ma, Richard A. Battye +7
We discuss the detectability of large-scale HI intensity fluctuations using the FAST telescope. We present forecasts for the accuracy of measuring the Baryonic Acoustic Oscillation…
The BINGO Project IV: Simulations for mission performance assessment and preliminary component separation steps
Vincenzo Liccardo, Eduardo J. de Mericia, Carlos A. Wuensche +21
The large-scale distribution of neutral hydrogen (HI) in the Universe is luminous through its 21 cm emission. The goal of the Baryon Acoustic Oscillations from Integrated Neutral G…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
Observations of Galactic star-forming regions with the Cosmic Background Imager at 31 GHz
Constantinos Demetroullas, Clive Dickinson, Dimitrios Stamadianos +6
Studies of the diffuse Galactic radio emission are interesting both for better understanding the physical conditions in our Galaxy and for minimising the contamination in cosmologi…
Joint power spectrum and voxel intensity distribution forecast on the CO luminosity function with COMAP
HÃ¥vard Tveit Ihle, Dongwoo Chung, George Stein +12
We develop a framework for joint constraints on the CO luminosity function based on power spectra (PS) and voxel intensity distributions (VID), and apply this to simulations of COM…
Impact of Simulated 1/f Noise for HI Intensity Mapping Experiments
Stuart Harper, Clive Dickinson, Richard Battye +5
Cosmology has entered an era where the experimental limitations are not due to instrumental sensitivity but instead due to inherent systematic uncertainties in the instrumentation…
Constraining the Anomalous Microwave Emission Mechanism in the S140 Star Forming Region with Spectroscopic Observations Between 4 and 8 GHz at the Green Bank Telescope
Maximilian H. Abitbol, Bradley R. Johnson, Glenn Jones +2
Anomalous microwave emission (AME) is a category of Galactic signals that cannot be explained by synchrotron radiation, thermal dust emission, or optically thin free-free radiation…
Cosmology with Phase 1 of the Square Kilometre Array; Red Book 2018: Technical specifications and performance forecasts
Square Kilometre Array Cosmology Science Working Group, David J. Bacon, Richard A. Battye +44
We present a detailed overview of the cosmological surveys that will be carried out with Phase 1 of the Square Kilometre Array (SKA1), and the science that they will enable. We hig…
