Consistently Reproducing Early Galaxy Observations and 21-cm Signal during the Epoch of Reionization
Michele Bianco, Sambit K. Giri, Arghyadeep Basu\orcidlink +5
In the standard cosmological model, galaxies forming within dark matter haloes are the primary drivers of the Epoch of Reionization (EoR). The complex physics of galaxy formation i…
Machine Learning and the SKA for Cosmic Dawn and the Epoch of Reionization
Anshuman Acharya, Michele Bianco, Daniela Breitman +18
When operational, the SKA will generate unprecedented amounts of data and provide exquisite sensitivity for 21 cm tomography of Cosmic Dawn (CD) and the Epoch of Reionization (EoR)…
Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
Imaging the 21-cm Signal from the Cosmic Dawn & Epoch of Reionization and the Connection with the Global Signal
Satadru Bag, Michele Bianco, Samir Choudhuri +12
The original baseline design for SKA-Low was motivated by the ability to produce tomographic images of the redshifted 21-cm signal, thus allowing the research field to move beyond…
Implicit inference of the reionization history with higher-order statistics of the 21-cm signal
Nicolas Cerardi, Sambit K. Giri, Michele Bianco +9
The Epoch of Reionization (EoR), when the first luminous sources ionised the intergalactic medium, represents a new frontier in cosmology. The Square Kilometre Array Observatory (S…
Exploring the Early Universe with Deep Learning
Emmanuel de Salis, Massimo De Santis, Davide Piras +9
Hydrogen is the most abundant element in our Universe. The first generation of stars and galaxies produced photons that ionized hydrogen gas, driving a cosmological event known as…
Mapping neutral islands during end stages of reionization with photometric intergalactic medium tomography
Sambit K. Giri, Koki Kakiichi, Michele Bianco +1
During the epoch of reionization (EoR), the first generation of luminous sources in our Universe emitted ionizing photons that almost completely ionized the gas in the intergalacti…
Exploring the effect of different cosmologies on the Epoch of Reionization 21-cm signal with POLAR
Anshuman Acharya, Qing-bo Ma, Sambit K. Giri +8
A detection of the 21-cm signal power spectrum from the Epoch of Reionization is imminent, thanks to consistent advancements from telescopes such as LOFAR, MWA, and HERA, along wit…
Deep learning approach for identification of HII regions during reionization in 21-cm observations -- III. image recovery
Michele Bianco, Sambit. K. Giri, Rohit Sharma +7
The low-frequency component of the upcoming Square Kilometre Array Observatory (SKA-Low) will be sensitive enough to construct 3D tomographic images of the 21-cm signal distributio…
The 21-cm signal during the end stages of reionization
Sambit K. Giri, Michele Bianco, Timothée Schaeffer +3
During the epoch of reionization (EoR), the 21-cm signal allows direct observation of the neutral hydrogen (HI) in the intergalactic medium (IGM). In the post-reionization era, thi…
BIPP: An efficient HPC implementation of the Bluebild algorithm for radio astronomy
Emma Tolley, Simon Frasch, Etienne Orliac +6
The Bluebild algorithm is a new technique for image synthesis in radio astronomy which decomposes the sky into distinct energy levels using functional principal component analysis.…
