Precision requirements for interferometric gridding in 21-cm power spectrum analysis
A. R. Offringa, F. Mertens, S. van der Tol +4
We analyse the accuracy of radio interferometric gridding of visibilities with the aim to quantify the Epoch of Reionization (EoR) 21-cm power spectrum bias caused by gridding, ult…
Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
The TeV-emitting radio galaxy 3C 264. VLBI kinematics and SED modeling
B. Boccardi, G. Migliori, P. Grandi +5
In March 2018, Mukherjee (2018) reported the detection by VERITAS of very-high-energy emission (VHE; > 100 GeV) from 3C 264. This is the sixth, and second most distant, radio galax…
The impact of interference excision on 21-cm Epoch of Reionization power spectrum analyses
A. R. Offringa, F. Mertens, L. V. E. Koopmans
We investigate the implications of interference detection for experiments that are pursuing a detection of the redshifted 21-cm signals from the Epoch of Reionization. Interference…
