The far-infrared/radio correlation and radio spectral index of galaxies in the SFR–M∗ plane up to z~2 [PDF]

, 2014
We study the evolution of the radio spectral index and far-infrared/radio correlation (FRC) across the star-formation rate – stellar masse (i.e. SFR–M∗) plane up to z ~ 2.

The Intrinsic Sizes of Odd Radio Circles

The Astrophysical Journal
A 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 ...

The radio properties of a complete, X-ray selected sample of nearby, massive elliptical galaxies

, 2010
We investigate the radio properties of a complete sample of nearby, massive, X-ray bright elliptical and S0 galaxies. Our sample contains 18 galaxies with ROSAT All-Sky Survey X-ray fluxes Fx_(0.1-2.4 keV) > 3 x 10^(-12) erg/s/cm^2, within a distance of ...

Radiogalaxies in the Sloan Digital Sky Survey: spectral index-environment correlations [PDF]

, 2010
We analyze optical and radio properties of radiogalaxies detected in the Sloan Digital Sky Survey (SDSS). The sample of radio sources are selected from the catalogue of Kimball & Ivezi\'c (2008) with flux densities at 325, 1400 and 4850 MHz, using WENSS,

GOODS-HERSCHEL: STAR FORMATION, DUST ATTENUATION, AND THE FIR–RADIO CORRELATION ON THE MAIN SEQUENCE OF STAR-FORMING GALAXIES UP TO z ≃ 4 [PDF]

, 2014
We use deep panchromatic data sets in the GOODS-N field, from GALEX to the deepest Herschel far-infrared (FIR) and VLA radio continuum imaging, to explore the evolution of star-formation activity and dust attenuation properties of star-forming galaxies ...

The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431

The Astrophysical Journal
We 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.

Numerical modelling of the lobes of radio galaxies in cluster environments [PDF]

, 2013
We have carried out two-dimensional, axisymmetric, hydrodynamic numerical modelling of the evolution of radio galaxy lobes. The emphasis of our work is on including realistic hotgas environments in the simulations and on establishing what properties of ...

Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station

Bioelectromagnetics, Volume 46, Issue 8, December 2025.
ABSTRACT In the context of risk communication in mobile radio, a discussion has emerged whether exposure at common load of a base station should be presented in addition to the theoretical maximum, especially with 5G massive‐MIMO. However, a reproducible measurement method for instantaneous exposure independent of the utilization of the cell has yet to

VLA observations of a sample of galaxies with high far-infrared luminosities [PDF]

, 1987
Preliminary results are presented from a radio survey of galaxies detected by the IRAS minisurvey. It was found that the main difference between galaxies selected in the far infrared and those selected in the optical is that the former have higher radio ...
