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…
Enhancing the detectability of ionized Regions during the Epoch of Reionization
Rutvik Ashish Mahajan, Raghunath Ghara, Nishant Pradeep Deo +1
We present an improved matched filter method for detecting large ionized regions in 21 cm observations of the Epoch of Reionization. In addition to detection, the method constrains…
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…
The Effect of Large Optical Depths on the Non-Gaussian 21-cm signal from Cosmic Dawn
Iffat Nasreen, Kanan K. Datta, Abinash K. Shaw +6
During the Cosmic Dawn (CD), the HI 21-cm optical depth ( ) in the intergalactic medium can become significantly large. Consequently, the second and higher-order terms of …
Detecting ionized bubbles around luminous sources during the reionization era using HI 21-cm signal
Arnab Mishra, Chandra Shekhar Murmu, Kanan K. Datta +4
Measuring the properties of the intergalactic medium (IGM) and sources during the Epoch of Reionization (EoR) is of immense importance. We explore the prospects of probing the IGM…
