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…
Pilot study and early results of the Cosmic Filaments and Magnetism Survey with Nenufar: the Coma cluster field
Bonnassieux Etienne, Evangelia Tremou, Julien N. Girard +9
NenuFAR, the New Extension in Nancay Upgrading LOFAR, is currently in its early science phase. It is in this context that the Cosmic Filaments and Magnetism Pilot Survey is observi…
SEAGLE--III: Towards resolving the mismatch in the dark-matter fraction in early-type galaxies between simulations and observations
Sampath Mukherjee, Léon V. E. Koopmans, Crescenzo Tortora +4
The central dark-matter fraction of galaxies is sensitive to feedback processes during galaxy formation. Strong gravitational lensing has been effective in the precise measurement…
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…
High-quality strong lens candidates in the final Kilo Degree survey footprint
R. Li, N. R. Napolitano, C. Spiniello +16
We present 97 new high-quality strong lensing candidates found in the final , that completed the full area of the Kilo-Degree Survey (Ki…
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…
