The Astrophysical JournalWe report new radio observations of SDSS J090122.37+181432.3, a strongly lensed star-forming galaxy at z = 2.26. We image 1.4 GHz ( L -band) and 3 GHz ( S -band) continuum using the Very Large Array (VLA) and 1.2 mm (band 6) continuum with Atacama Large ...

LoTSS/HETDEX: Optical quasars I. Low-frequency radio properties of optically selected quasars [PDF]
, 2018 The radio-loud/radio-quiet (RL/RQ) dichotomy in quasars is still an open question. Although it is thought that accretion onto supermassive black holes in the centre the host galaxies of quasars is responsible for some radio continuum emission, there is still a debate as to whether star formation or active galactic nuclei (AGN) activity dominate the ...

Deciphering the radio-star formation correlation on kpc-scales III. Radio-dim and bright regions in spiral galaxies [PDF]
arXiv, 2023 The relation between the resolved star formation rate per unit area and the non-thermal radio continuum emission is studied in 21 Virgo cluster galaxies and the two nearby spiral galaxies, NGC6946 and M51. For the interpretation and understanding of our results we used a 3D model where star formation, 2D cosmic ray (CR) propagation, and the physics of ...

The Astrophysical JournalThe nearby ultraluminous infrared galaxy (ULIRG) IRAS F01004−2237 exhibits 100 kpc scale continuum emission at radio wavelengths. The absence of extended X-ray emission in IRAS F01004−2237 has suggested an active galactic nucleus (AGN) origin for the ...

The characteristic polarized radio continuum distribution of cluster spiral galaxies [PDF]
, 2007 Deep observations of 6cm polarized radio continuum emission of 8 Virgo spiral galaxies are presented. All galaxies show strongly asymmetric distributions of polarized intensity with elongated ridges located in the outer galactic disk. Such features are not found in existing observations of polarized radio continuum emission of field spiral galaxies ...

Sub-arcsecond imaging of the radio continuum and neutral hydrogen in the Medusa merger [PDF]
, 2005 We present sub-arcsecond, Multi-Element Radio Linked Interferometer (MERLIN) observations of the decimetre radio continuum structure and neutral hydrogen (HI) absorption from the nuclear region of the starburst galaxy NGC 4194 (the Medusa Merger). The continuum structure of the central kiloparsec of the Medusa has been imaged, revealing a pair of ...

HCO+ and Radio Continuum Emission from the Star Forming Region G75.78+0.34
Advances in Astronomy, 2014 We present 1.3 and 3.6 cm radio continuum images and a HCO+ spectrum of the massive star forming region G75.78+0.34 obtained with the Very Large Array (VLA) and with the Berkley Illinois Maryland Association (BIMA) interferometer.

On the Dynamical Evolution of the Asteroid Belt in a Massive Star–Neutron Star Binary
The Astrophysical JournalSome fast radio bursts (FRBs) exhibit repetitive behaviors, and their origins remain enigmatic. It has been argued that repeating FRBs could be produced by the interaction between a neutron star and an asteroid belt.
