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…
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…
-probe: A new diagnostic of dark energy based on
Satadru Bag, Ryan E. Keeley, Varun Sahni +1
Recent DESI data suggest that dark energy may be evolving and motivate the use of model-independent diagnostics such as and probes of the equation of state (EoS) of dark en…
Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics III: Impact of the lightcone effect
Hemanth Potluri, Manas Mohit Dosibhatla, Leon Noble +6
The redshifted 21-cm signal emitted by neutral Hydrogen (HI) is a promising probe to understand the evolution of the topology of ionized regions during the Epoch of Reionization (E…
Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics. Part II. Impact of the realistic foreground and instrumental noise on synthetic SKA1-Low observations
Samit Kumar Pal, Saswata Dasgupta, Abhirup Datta +3
The Largest Cluster Statistics\,(LCS) analysis of the redshifted 21\,cm maps has been demonstrated to be an efficient and robust method for following the time evolution of the larg…
