The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431
The Astrophysical JournalWe present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a starburst system containing three tidally distorted disk galaxies.

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases
ChemBioChem, Volume 27, Issue 11, 15 June 2026.Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

The Seeding of Cosmic Ray Electrons by Cluster Radio Galaxies: A Review
GalaxiesRadio galaxies in clusters of galaxies are a prominent reservoir of magnetic fields and of non-thermal particles, which become mixed with the intracluster medium.

Spectral differences between radio galaxies and quasars
, 1990 IT has been suggested recently1-4 that two classes of radio-loud extragalactic object, narrow-line radio galaxies and quasars, are intrinsically similar, differing only in the angle from which they are seen by the observer.

Tracing Quenching by Radio Active Galactic Nuclei in Post-starburst Galaxies at Cosmic Noon
The Astrophysical JournalWe present a radio continuum study of photometrically selected post-starburst galaxies (PSBs) at cosmic noon (0.5 10 ^11 M _⊙ ). In contrast, 1.4 GHz-detected quiescent galaxies exhibit luminosities reaching the radio-loud regime and show a higher ...

Searches for high redshift radio galaxies [PDF]
, 1998 We have started a search for High Redshift Radio Galaxies (HzRGs) in an area covering 7 sr by selecting a sample of Ultra Steep Spectrum (USS) sources with a low flux density cut-off S{sub 1400} > 10 mJy and a steep spectral index {alpha} 3 5 Our search

Radio galaxies and their environment
, 1993 The relationships between radio galaxies and their environment are varied, complex, and evolve with cosmic epoch. Basic questions are what role the environment plays in triggering and fuelling (radio) galaxy activity what the effects of this activity are
