Radio Sources and Their Environment [PDF]

Highlights of Astronomy, 2002
AbstractThe properties of radio sources in and outside of Abell clusters are reviewed. The properties of sources in and out of Abell clusters are shown to be surprisingly similar. However, sources in dense cluster cores do not fit this pattern and, as in Virgo A (M87), have a significant, sometimes dominant input of energy into the “cooling core ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

A search for steep spectrum radio relics and halos with the GMRT [PDF]

, 2009
Context: Diffuse radio emission, in the form of radio halos and relics, traces regions in clusters with shocks or turbulence, probably produced by cluster mergers.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Radio and spectroscopic properties of miniature radio galaxies: revealing the bulk of the radio-loud AGN population

, 2009
We explore radio and spectroscopic properties of a sample of 14 miniature radio galaxies, i.e. early-type core galaxies hosting radio-loud AGN of extremely low radio power, 10^(27-29) erg s^(-1) Hz^(-1) at 1.4 GHz.

The new class of FR0 radio galaxies [PDF]

, 2015
Are the FRI and FRII radio galaxies representative of the radio-loud (RL) AGN population in the local Universe? Recent studies on the local low-luminosity radio sources cast lights on an emerging population of compact radio galaxies which lack extended ...

Sources of the Radio Background Considered

, 2009
We investigate different scenarios for the origin of the extragalactic radio background. The surface brightness of the background, as reported by the ARCADE 2 collaboration, is several times higher than that which would result from currently observed radio sources.

The core dominance parameter and \emph{Fermi} detection of extragalactic radio sources

, 2016
In this paper, by cross-correlating an archive sample of 542 extragalactic radio sources with the \emph{Fermi}-LAT Third Source Catalog(3FGL), we have compiled a sample of 80 $\gamma$-ray sources and 462 non-\emph{Fermi} sources with available core ...
