EXPLORING THE COSMIC REIONIZATION EPOCH IN FREQUENCY SPACE: AN IMPROVED APPROACH TO REMOVE THE FOREGROUND IN 21 cm TOMOGRAPHY

TL;DR: In this article, the authors re-examine the separation approaches based on the quadratic polynomial fitting technique in frequency space to investigate whether they work satisfactorily with complex foreground by quantitatively evaluating the quality of restored 21 cm signals in terms of sample statistics.
Journal ArticleDOI

Radio sources in the ncp region observed with the 21 centimeter array

TL;DR: In this article, the authors presented a catalog of 624 radio sources detected around the North Celestial Pole (NCP) with the 21 Centimeter Array (21CMA), a radio interferometer dedicated to the statistical measurement of the epoch of reionization (EoR).

Separating the EoR signal with a convolutional denoising autoencoder: a deep-learning-based method

TL;DR: This paper proposes a novel deep-learning-based method that uses a 9-layer convolutional denoising autoencoder (CDAE) to separate the EoR signal and concludes that, by hierarchically learning sophisticated features through multiple Convolutional layers, the CDAE is a powerful tool that can be used to overcome the complicated beam effects and accurately separate the NLP signal.
