The Imprint of the Baryon Acoustic Oscillations (BAO) in the Cross-correlation of the Redshifted HI 21-cm Signal and the Ly-alpha Forest
Tapomoy Guha Sarkar, Somnath Bharadwaj
The cross-correlation of the Ly-alpha forest and redshifted 21-cm emission has recently been proposed as an observational tool for mapping out the large-scale structures in the pos…
Constraining large scale HI bias using redshifted 21-cm signal from the post-reionization epoch
Tapomoy Guha Sarkar, Sourav Mitra, Suman Majumdar +1
In the absence of complex astrophysical processes that characterize the reionization era, the 21-cm emission from neutral hydrogen (HI) in the post-reionization epoch is believed t…
Metric deformation and boundary value problems in 2D
Subhasis Panda, Tapomoy Guha Sarkar, S Pratik Khastgir
A new analytical formulation is prescribed to solve the Helmholtz equation in 2D with arbitrary boundary. A suitable diffeomorphism is used to annul the asymmetries in the boundary…
