The Local Dimension: a method to quantify the Cosmic Web
Prakash Sarkar, Somnath Bharadwaj
It is now well accepted that the galaxies are distributed in filaments, sheets and clusters all of which form an interconnected network known as the Cosmic Web. It is a big challen…
Magnetohydrodynamic turbulence in supernova remnants
Nirupam Roy, Somnath Bharadwaj, Prasun Dutta +1
We present estimates of the angular power spectra of the synchrotron radiation intensity fluctuations at 6 and 20 cm for the shell type supernova remnant Cas A and the filled-centr…
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…
Estimation of Cosmological Parameters from HI Observations of Post-reionization Epoch
Somnath Bharadwaj, Shiv K. Sethi, Tarun Deep Saini
The emission from neutral hydrogen (HI) clouds in the post-reionization era (z < 6), too faint to be individually detected, is present as a diffuse background in all low frequency…
Exploring star formation using the filaments in the Sloan Digital Sky Survey Data Release Five (SDSS DR5)
Biswajit Pandey, Somnath Bharadwaj
We have quantified the average filamentarity of the galaxy distribution in seven nearly two dimensional strips from the SDSS DR5 using a volume limited sample in the absolute magni…
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…
