Extracting the Epoch of Reionization Signal with 3D U-Net Neural Networks Using Data-driven Systematic Effect Model
Li-Yang Gao, Léon V. E. Koopmans, Florent G. Mertens +11
Neutral hydrogen (HI) serves as a crucial probe for the Cosmic Dawn and the Epoch of Reionization (EoR). Actual observations of the 21-cm signal often encounter challenges such as…
The radio properties of the JWST-discovered AGN
G. Mazzolari, R. Gilli, R. Maiolino +23
We explore the radio emission of JWST-selected Broad Line AGN (BLAGN, or type 1) in the GOODS-N field. We use deep radio data at different frequencies (144\,MHz, 1.5\,GHz, 3\,GHz,…
Stellar-gas kinematic misalignments in EAGLE: lifetimes and longevity of misaligned galaxies
Maximilian K. Baker, Timothy A. Davis, Freeke van de Voort +1
The dominant processes by which galaxies replenish their cold gas reservoirs remain disputed, especially in massive galaxies. Stellar-gas kinematic misalignments offer an opportuni…
LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. II. Analysis
S. Piras, C. Horellou, J. Conway +7
Deep polarization surveys at low radio frequencies are key to cosmic magnetism studies: Larger catalogs of polarized extragalactic sources and increased precision on Faraday rotati…
Non-thermal emission in galaxy groups at extremely low frequency: the case of A1213
T. Pasini, V. H. Mahatma, M. Brienza +7
Galaxy clusters and groups are the last link in the chain of hierarchical structure formation. Their environments can be significantly affected by outbursts from AGN, especially in…
On the nature of LOFAR RMs and new constraints on magnetic fields in cosmic filaments and on magnetogenesis scenarios
E. Carretti, F. Vazza, S. P. O'Sullivan +6
The measurement of magnetic fields in cosmic web filaments can be used to reveal the magnetogenesis of the Universe. In previous work, we produced first estimates of the field stre…
Cocoon shock, X-ray cavities and extended Inverse Compton emission in Hercules A: clues from Chandra observations
F. Ubertosi, Y. Gong, P. Nulsen +7
We present a detailed analysis of jet activity in the radio galaxy 3C348 at the center of the galaxy cluster Hercules A. We use archival Chandra data to investigate the jet-driven…
Black hole jets on the scale of the Cosmic Web
Martijn S. S. L. Oei, Martin J. Hardcastle, Roland Timmerman +10
Jets launched by supermassive black holes transport relativistic leptons, magnetic fields, and atomic nuclei from the centres of galaxies to their outskirts and beyond. These outfl…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
High-pass Filter Periodogram: An Improved Power Spectral Density Estimator for Unevenly Sampled Data
Ezequiel Albentosa-Ruiz, Nicola Marchili
Accurate time series analysis is essential for studying variable astronomical sources, where detecting periodicities and characterizing power spectral density (PSD) are crucial. Th…
