21-cm Signal from the Epoch of Reionization: A Machine Learning upgrade to Foreground Removal with Gaussian Process Regression
Anshuman Acharya, Florent Mertens, Benedetta Ciardi +7
In recent years, a Gaussian Process Regression (GPR) based framework has been developed for foreground mitigation from data collected by the LOw-Frequency ARray (LOFAR), to measure…
First upper limits on the 21 cm signal power spectrum from cosmic dawn from one night of observations with NenuFAR
S. Munshi, F. G. Mertens, L. V. E. Koopmans +24
The redshifted 21 cm signal from neutral hydrogen is a direct probe of the physics of the early universe and has been an important science driver of many present and upcoming radio…
The morphology of the redshifted 21-cm signal from the Cosmic Dawn
Raghunath Ghara, Satadru Bag, Saleem Zaroubi +1
The spatial fluctuations in the tomographic maps of the redshifted 21-cm signal from the Cosmic Dawn (CD) crucially depend on the size and distribution of the regions with gas temp…
POLAR -- I: linking the 21-cm signal from the epoch of reionization to galaxy formation
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +5
To self-consistently model galactic properties, reionization of the intergalactic medium, and the associated 21-cm signal, we have developed the algorithm polar by integrating the…
Studying the Multi-frequency Angular Power Spectrum of the Cosmic Dawn 21-cm Signal
Abinash Kumar Shaw, Raghunath Ghara, Saleem Zaroubi +5
The light-cone (LC) anisotropy arises due to cosmic evolution of the cosmic dawn 21-cm signal along the line-of-sight (LoS) axis of the observation volume. The LC effect makes the…
