Scintillation noise power spectrum and its impact on high redshift 21-cm observations
H. K. Vedantham, L. V. E. Koopmans
Visibility scintillation resulting from wave propagation through the turbulent ionosphere can be an important sources of noise at low radio frequencies ( MHz). Many…
Linear polarization structures in LOFAR observations of the interstellar medium in the 3C196 field
V. Jelić, A. G. de Bruyn, V. N. Pandey +21
This study aims to characterize linear polarization structures in LOFAR observations of the interstellar medium (ISM) in the 3C196 field, one of the primary fields of the LOFAR-Epo…
The Cosmic Dawn and Epoch of Reionization with the Square Kilometre Array
L. V. E. Koopmans, J. Pritchard, G. Mellema +42
Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR) (15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of sou…
Simulating the 21cm forest detectable with LOFAR and SKA in the spectra of high-z GRBs
B. Ciardi, S. Inoue, F. B. Abdalla +26
We investigate the feasibility of detecting 21cm absorption features in the afterglow spectra of high redshift long Gamma Ray Bursts (GRBs). This is done employing simulations of c…
Polarization leakage in Epoch of Reionization windows: I. LOFAR observations of the 3C196 field
K. M. B. Asad, L. V. E. Koopmans, V. Jelić +25
Detection of the 21-cm signal coming from the epoch of reionization (EoR) is challenging especially because, even after removing the foregrounds, the residual Stokes maps conta…
All-sky signals from recombination to reionization with the SKA
Ravi Subrahmanyan, N. Udaya Shankar, Jonathan Pritchard +1
Cosmic evolution in the hydrogen content of the Universe through recombination and up to the end of reionization is expected to be revealed as subtle spectral features in the unifo…
