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…
Cosmic variance suppression in radiation-hydrodynamic modeling of the reionization-era 21-cm signal
Anshuman Acharya, Enrico Garaldi, Benedetta Ciardi +1
The 21-cm line emitted by neutral hydrogen is the most promising probe of the Epoch of Reionization (EoR). Multiple radio interferometric instruments are on the cusp of detecting i…
Skew spectrum and smoothed skewness of 21-cm signals from epoch of reionization
Qing-Bo Ma, Ling Peng
Due to the non-linear ionizing and heating processes, the 21-cm signals from epoch of reionization (EoR) are expected to have strong non-Gaussian fluctuations. In this paper, we us…
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…
