The CMBR ISW and HI 21-cm Cross-correlation Angular Power Spectrum
Tapomoy Guha Sarkar, Kanan K. Datta, Somnath Bharadwaj
The late-time growth of large scale structures (LSS) is imprinted in the CMBR anisotropy through the Integrated Sachs Wolfe (ISW) effect. This is perceived to be a very important o…
Simulating the impact of HI fluctuations on matched filter search for ionized bubbles in redshifted 21 cm maps
Kanan K. Datta, Suman Majumdar, Somnath Bharadwaj +1
Extending the formalism of Datta, Bharadwaj & Choudhury (2007) for detecting ionized bubbles in redshifted 21 cm maps using a matched-filtering technique, we use different simulati…
Detecting ionized bubbles in redshifted 21 cm maps
Kanan K. Datta, Somnath Bharadwaj, T. Roy Choudhury
The reionization of the Universe, it is believed, occurred by the growth of ionized regions (bubbles) in the neutral intergalactic medium (IGM). We study the possibility of detecti…
The multi-frequency angular power spectrum of the epoch of reionization 21 cm signal
Kanan K. Datta, T. Roy Choudhury, Somnath Bharadwaj
Observations of redshifted 21cm radiation from HI at high redshifts is an important future probe of reionization. We consider the Multi-frequency Angular Power Spectrum (MAPS) to q…
