Fooled by mass? Recovering the relation of quasars from their X-ray variability
Matilde Signorini, Andrea Sacchi, Bartolomeo Trefoloni +7
We measure the relation between the X-ray photon index and the Eddington ratio in unobscured type-1 quasars, using as parent sample the cross-match of the SDSS DR16Q…
Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies
M. J. Hardcastle, L. Bisigello, M. Bondi +154
The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions…
The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654
Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27
We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…
Unveiling the Cosmic Dawn with SHARP: Probing extended Lyman- nebulae in a Universe less than 600 Myr old
Susanna Bisogni, Giustina Vietri, Enrico Piconcelli +5
The existence of luminous quasars just a few hundred million years after the Big Bang challenges our understanding of both black hole growth and galaxy formation and evolution. The…
