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 ...

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

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

Constraining Annihilating Dark Matter Using the Multifrequency Radio Flux Profiles of the M33 Galaxy
The Astrophysical JournalRadio data can give stringent constraints for annihilating dark matter. In general, radio observations can detect very accurate radio flux density with high resolution and different frequencies for nearby galaxies.

A Linearly Polarized Merger Shock Down to 550 MHz: A uGMRT Study of the Merging Cluster A746
The Astrophysical JournalRadio relics, arc-like polarized sources with highly aligned magnetic fields, are typically found on the outskirts of merging galaxy clusters. The magnetoionic media responsible for the significant coherence observed in radio relics remain poorly ...

3D Localization of FRB 20190425A for Its Potential Host Galaxy and Implications
The Astrophysical JournalFast radio bursts (FRBs) are high-energy, short-duration phenomena in radio astronomy. Identifying their host galaxies can provide insights into their mysterious origins. In this paper, we introduce a novel approach to identifying potential host galaxies

A Shocked Wind Interpretation of an Odd Radio Circle
The Astrophysical JournalOdd radio circles (ORCs) are a new class of extragalactic object, with large rings of faint radio continuum emission typically spanning hundreds of kiloparsecs; their origins are unknown.
