Follow-up of SN 2025wny III: Spectroscopic Time-delay Measurements of a Strongly Gravitationally Lensed Superluminous Supernova
Joel Johansson, Edvard Mörtsell, Ariel Goobar +30
We present spatially resolved spectra and infer the time-delays between the multiple images of the strongly gravitationally lensed superluminous supernova (SLSN) 2025wny at z=2.015…
Follow-up of SN 2025wny II: Superluminous Supernova Physics at Cosmic Noon
Maggie L. Li, Lin Yan, Anamaria Gkini +46
SN 2025wny is a gravitationally lensed, hydrogen-poor superluminous supernova (SLSN-I) at z = 2.015. To date, it is the most extensively observed high-redshift core-collapse SN and…
Minimum Energies and Magnetic Field Strengths of Edge-brightened Compact Symmetric Objects
Tirth D. Surti, Martijn S. S. L. Oei, Anthony C. S. Readhead +1
Compact symmetric objects (CSOs) are subkiloparsec radio sources with two-sided emission about a core resulting from jets that are not relativistically beamed towards the observer.…
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…
Search and analysis of giant radio galaxies with associated nuclei (SAGAN) V. Study of giant double-double radio galaxies from LoTSS DR2
Pratik Dabhade, Kshitij Chavan, D. J. Saikia +2
To test the hypothesis that megaparsec-scale giant radio galaxies (GRGs) experience multiple epochs of recurrent activity leading to their giant sizes and to understand the nature…
Constraining the giant radio galaxy population with machine learning and Bayesian inference
Rafaël I. J. Mostert, Martijn S. S. L. Oei, B. Barkus +6
Large-scale sky surveys at low frequencies, like the LOFAR Two-metre Sky Survey (LoTSS), allow for the detection and characterisation of unprecedented numbers of giant radio galaxi…
Luminous giants populate the dense Cosmic Web: The radio luminosity-environmental density relation for radio galaxies in action
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +6
Giant radio galaxies (GRGs, giant RGs, or giants) are megaparsec-scale, jet-driven outflows from accretion disks of supermassive black holes, and represent the most extreme pathway…
Finding AGN remnant candidates based on radio morphology with machine learning
Rafael I. J. Mostert, Raffaella Morganti, Marisa Brienza +6
Remnant radio galaxies represent the dying phase of radio-loud active galactic nuclei (AGN). Large samples of remnant radio galaxies are important for quantifying the radio galaxy…
An intergalactic medium temperature from a giant radio galaxy
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +5
The warm-hot intergalactic medium (warm-hot IGM, or WHIM) pervades the filaments of the Cosmic Web and harbours half of the Universe's baryons. The WHIM's thermodynamic properties…
Filamentary Baryons and Where to Find Them: A forecast of synchrotron radiation from merger and accretion shocks in the local Cosmic Web
Martijn S. S. L. Oei, Reinout J. van Weeren, Franco Vazza +3
We generate probabilistic predictions of the low-redshift () synchrotron Cosmic Web for half of the Northern Sky. In particular, we predict the contribution to the specifi…
The discovery of a radio galaxy of at least 5 Mpc
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +9
We discover what is in projection the largest known structure of galactic origin: a giant radio galaxy with a projected proper length of . The source,…
