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…

Sub-arcsecond resolution imaging of M 51 with the International LOFAR Telescope

Deepika Venkattu, Peter Lundqvist, Miguel Pérez-Torres +5

We present an International LOFAR Telescope sub-arcsecond resolution image of the nearby galaxy M 51 with a beam size of 0.436" x 0.366" and rms of 46 Jy. We compare this image…

Subarcsecond view on the high-redshift blazar GB 1508+5714 by the International LOFAR Telescope

A. Kappes, P. R. Burd, M. Kadler +14

Studies of the most distant AGNs allow us to test our current understanding of the physics present in radio-jetted AGNs across a range of environments. The decrease in apparent lum…

Extended X-ray emission around FR II radio galaxies: hotspots, lobes and galaxy clusters

Ana Jimenez-Gallardo, Francesco Massaro, Alessandro Paggi +20

We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge catalog (3CR) Chandra Snapshot Survey wit…

A plethora of diffuse steep spectrum radio sources in Abell 2034 revealed by LOFAR

T. W. Shimwell, J. Luckin, M. Brüggen +28

With Low-Frequency Array (LOFAR) observations, we have discovered a diverse assembly of steep spectrum emission that is apparently associated with the intra cluster medium (ICM) of…

Unveiling the Intrinsic X-ray Properties of Broad Absorption Line Quasars with a Relatively Unbiased Sample

Leah K. Morabito, Xinyu Dai, Karen M. Leighly +2

There is growing evidence of a higher intrinsic fraction of broad absorption line quasars (BALQSOs) than that obtained in optical surveys, on which most previous X-ray studies of B…
