Measurements of the diffuse Galactic synchrotron spectral index and curvature from MeerKLASS pilot data
Melis O. Irfan, Philip Bull, Mario G. Santos +6
21cm intensity mapping experiments are bringing an influx of high spectral resolution observational data in the MHz GHz regime. We use pilot MHz data fro…
Constraining beyond CDM models with 21cm intensity mapping forecast observations combined with latest CMB data
Maria Berti, Marta Spinelli, Balakrishna S. Haridasu +2
We explore constraints on dark energy and modified gravity with forecast 21cm intensity mapping measurements using the Effective Field Theory approach. We construct a realistic moc…
Radio antenna design for sky-averaged 21 cm cosmology experiments: the REACH case
J. Cumner, E. De Lera Acedo, D. I. L. de Villiers +35
Following the reported detection of an absorption profile associated with the 21~cm sky-averaged signal from the Cosmic Dawn by the EDGES experiment in 2018, a number of experiment…
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…
Gravitational waves HI intensity mapping: cosmological and astrophysical applications
Giulio Scelfo, Marta Spinelli, Alvise Raccanelli +3
Two of the most rapidly growing observables in cosmology and astrophysics are gravitational waves (GW) and the neutral hydrogen (HI) distribution. In this work, we investigate the…
