We present high-sensitivity eMERLIN radio images of the Seyfert galaxy NGC 4151 at 1.51 GHz. We compare the new eMERLIN images to those from archival MERLIN...
Radio observations of extreme ULXs: revealing the most powerful ULX radio nebula ever or the jet of an intermediate-mass black hole?
The most extreme ultraluminous X-ray sources (ULXs), with LX > 5 × 1040 erg s-1, are amongst the best candidates for hosting intermediate-mass black holes...
Radio source calibration for the Very Small Array and other cosmic microwave background instruments at around 30 GHz
Accurate calibration of data is essential for the current generation of cosmic microwave background (CMB) experiments. Using data from the Very Small Array (VSA...
ELAIS (European Large Area ISO Survey) is a project that has carried out a deep wide angle survey with ISO at 7, 15 and 90 μm over an area of ≡13 square degrees...
Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
We study the radio spectral properties of 2094 star-forming galaxies (SFGs) by combining our early science data from the MeerKAT International GHz Tiered...
Radio spectrum evolution and magnetic field in extreme GPS radio sources. The case of RXJ1459+3337
Aims:The knowledge of the properties of the youngest radio sources is very important in order to trace the earliest phase of the evolution of the radio emission...
Radio structures of the nuclei of nearby Seyfert galaxies and the nature of the missing diffuse emission
We present archival high-spatial-resolution VLA and VLBA data of the nuclei of seven of the nearest and brightest Seyfert galaxies in the Southern Hemisphere...
Supernova 1993J (SN 1993J) in M81, now classified as Type IIb, is a strongly emitting radio supernova whose size can be resolved and whose growth can be...
We examine the isotope production in star forming regions through a model of stellar-group population synthesis evolution. From this we obtain the light-curves...
