Dust and star formation in distant radio galaxies
, 2004 International audienceWe present the results of an observing programme with the Submillimetre Common User Bolometer Array (SCUBA) to measure the submillimetre (submm) dust continuum emission of 24 distant (z > 1) radio galaxies.

The Intrinsic Sizes of Odd Radio Circles
The Astrophysical JournalA new class of sources, the so-called odd radio circles (ORCs), have been discovered by recent sensitive, large-area radio continuum surveys. The distances of these sources have so far relied on photometric redshifts of optical galaxies found at the ...

LUMINOSITY-LINEAR SIZE RELATION FOR GALAXIES AND QUASARS WITH STEEP RADIO SPECTRUM
Odessa Astronomical Publications, 2016 Our data for sources with steep radio spectrum, detected with radio telescope UTR-2 at the decametre band give evidence on the great luminosities, linear sizes, characteristic ages of these objects.

What is the difference between radio galaxies and radio quasar galaxies?
The Astrophysical Journal, 1987 Deep optical imaging in the B and R band of about 50 luminous radio galaxies and radio QSOs in the redshift range 0.1-0.5 is reported. More than 80 percent of each type of object are optically interacting; about 60 percent are irregular in some way, and about 30 percent have tidal tails. Separations range from a few kpc to tens of kpc. About 30 percent

X-ray emission in powerful radio galaxies and quasars [PDF]
, 1994 ROSAT is the first mission to have detected X‐ray emission in radio galaxies which are both powerful (l_(178 MHz)>10^(27) W Hz^(−1) sr^(−1)) and distant (z>0.4), enabling test of ‘‘unified schemes’’ through a comparison of the X‐ray and radio properties ...

Peculiar Galaxies and Radio Sources
Science, 1966 Pairs of radio sources which are separated by from 2° to 6° on the sky have been investigated. In a number of cases peculiar galaxies have been found approximately midway along a line joining the two radio sources. The central peculiar galaxies belong mainly to a certain class in the recently compiled Atlas of Peculiar Galaxies

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...
