Degree-Scale Galactic Radio Emission at 122 MHz around the North Celestial Pole with LOFAR-AARTFAAC
B. K. Gehlot, L. V. E. Koopmans, A. R. Offringa +11
Aims: Contamination from bright diffuse Galactic thermal and non-thermal radio emission poses crucial challenges in experiments aiming to measure the 21-cm signal of neutral hydrog…
A numerical study of 21-cm signal suppression and noise increase in direction-dependent calibration of LOFAR data
M. Mevius, F. Mertens, L. V. E. Koopmans +14
We investigate systematic effects in direction dependent gain calibration in the context of the Low-Frequency Array (LOFAR) 21-cm Epoch of Reionization (EoR) experiment. The LOFAR…
SKA-Low Intensity Mapping Pathfinder Updates: Deeper 21 cm Power Spectrum Limits from Improved Analysis Frameworks
Nichole Barry, Gianni Bernardi, Bradley Greig +2
The Square Kilometre Array (SKA) is a planned radio interferometer of unprecedented scale that will revolutionize low-frequency radio astronomy when completed. In particular, one o…
Exploring the Cosmic Dawn with NenuFAR
F. G. Mertens, B. Semelin, L. V. E. Koopmans
The exploration of the Cosmic Dawn, the period of the Universe during which the first stars and galaxies were formed, is one of the last frontiers of modern astronomy and cosmology…
A detailed kinematic study of 3C 84 and its connection to Gamma-rays
Jeffrey A. Hodgson, Bindu Rani, Junghwan Oh +7
3C 84 (NGC 1275) is the bright radio core of the Perseus Cluster. Even in the absence of strong relativistic effects, the source has been detected at Gamma-rays up to TeV energies.…
21cm signal predictions at Cosmic Dawn and Reionization with coupled radiative-hydrodynamics
Nicolas J. F. Gillet, Dominique Aubert, Florent G. Mertens +1
The process of heating and reionization of the Universe at high redshift links small scale structures/galaxy formation and large scale inter-galactic medium properties. Even if the…
