Square Kilometer Array Synergies for the Epoch of Reionization and Cosmic Dawn

Anirban Chakraborty, Tirthankar R. Choudhury, Kanan K. Datta +15

Synergies with other instruments will be essential in making, verifying, and interpreting a detection of the cosmic 21-cm signal from the Epoch of Reionization (EoR) and Cosmic Daw…

High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization

Rennan Barkana, Oliver Basquette, Ankita Bera +22

In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…

Overview of 21cm Experiments at high redshift with SKAO

CD Science Working Group, Gianni Bernardi, Daniela Breitman +81

We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…

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…

Probing ionized bubbles around luminous sources during reionization with SKA 21-cm observations

Arnab Mishra, Kanan Kumar Datta, Chandra Shekhar Murmu +3

Detecting and characterizing individual ionized bubbles during the Epoch of Reionization (EoR) using the redshifted HI 21-cm signal provides a direct probe of the early ionizing so…

ELAIS-N1 deep field uGMRT Band-2: constraints on diffuse Galactic synchrotron emission power spectrum

Rashmi Sagar, Abhirup Datta, Arnab Chakraborty +13

We present high sensitivity, low radio frequency continuum observations of the ELAIS-N1 field with 32 hours of observations of the uGMRT Band-2 ( MHz) covering $5.86\,\tex…
