CosmoUiT: A Vision Transformer-UNet Hybrid for Fast and Accurate Emulation of 21-cm Maps from the Epoch of Reionization
Prasad Rajesh Posture, Yashrajsinh Mahida, Suman Majumdar +1
The observation of the redshifted 21-cm signal from the intergalactic medium will probe the epoch of reionization (EoR) with unprecedented detail. Various simulations are being dev…
From ANN to BNN: Inferring Reionization Parameters using Uncertainty-aware Emulators of 21-cm Summaries
Yashrajsinh Mahida, Sanjay Kumar Yadav, Suman Majumdar +6
Inferring astrophysical parameters from radio interferometric observations of the redshifted 21-cm signal from the Epoch of Reionization (EoR) is a challenging yet crucial task. Th…
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…
Ultraviolet photon production rates of the first stars: Impact on the He II 1640 Å emission line from primordial star clusters and the 21-cm signal from cosmic dawn
Joel Wasserman, Erik Zackrisson, Jiten Dhandha +3
The first stars, the chemically pristine Population III, likely played an important role in heating the intergalactic medium during the epoch of cosmic dawn. The very high effectiv…
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…
Impact of Calibration and Position Errors on Astrophysical Parameters of the HI 21cm Signal
Anshuman Tripathi, Abhirup Datta, Aishrila Mazumder +1
The Epoch of Reionization (EoR) and Cosmic Dawn (CD) are pivotal stages during the first billion years of the universe, exerting a significant influence on the development of cosmi…
