Radio Halos in Galaxy Clusters as unveiled by the SKA telescope

R. Cassano, G. Di Gennaro, V. Cuciti +24

Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…

Foreground Characterization and Mitigation in the Observations of the CD/EoR with the SKA

Philip Bull, Jacob Burba, Emilio Ceccotti +20

The Square Kilometre Array (SKA), with its unprecedented sensitivity, frequency coverage, and large collecting area, is poised to revolutionize our understanding of the Cosmic Dawn…

Cosmology with Multi-Wavelength Line Intensity Mapping Synergies in the SKAO Era

Debanjan Sarkar, Suman Majumdar, Chandra Shekhar Murmu +21

Line intensity mapping (LIM) has emerged as a powerful tool for surveying the large-scale structure of the Universe across cosmic time by measuring spatial fluctuations in the cumu…

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…

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…

Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders

Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21

The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…

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 Reionization up to the Mark: The Marked Power Spectrum to unveil the HI 21-cm signal from the EoR

Vishrut Pandya, Leon Noble, Suman Majumdar +3

The redshifted 21-cm signal from neutral hydrogen (HI) in the intergalactic medium (IGM) is a powerful probe of the Epoch of Reionization (EoR). Owing to the complex growth and mor…

Mitigating residual foregrounds and systematic errors in SKA1-Low AA* EoR observations via Bayesian Gaussian Process Regression

Samit Kumar Pal, Abhirup Datta, Aishrila Mazumder +1

The redshifted 21\,cm line is an emerging tool in observational cosmology that can serve as a direct probe of the intergalactic medium throughout the cosmic timeline. However, the…

Tracing Large-Scale Structure Morphology with Multiwavelength Line Intensity Maps

Manas Mohit Dosibhatla, Suman Majumdar, Chandra Shekhar Murmu +4

Line intensity mapping (LIM) is an emerging technique for probing the large-scale structure (LSS) in the post-reionisation era. This captures the integrated flux of a particular sp…
