Radio Continuum and Star Formation in CO-rich Early Type Galaxies

, 2007
In this paper we present new high resolution VLA 1.4 GHz radio continuum observations of five FIR bright CO-rich early-type galaxies and two dwarf early-type galaxies.

Exploring Neutral Hydrogen in Radio MOlecular Hydrogen Emission Galaxies (MOHEGs) and Prospects with the SKA

The Astrophysical Journal
Empirical studies of cold gas content are essential for comprehending the star formation activities and evolution in galaxies. However, it is not straightforward to understand these processes because they depend on various physical properties of the ...

Faint radio samples: the key to understanding radio galaxies [PDF]

arXiv, 1998
The large number of differences between high- and low-redshift radio galaxies have almost all been discovered by looking at the bright 3C sample of radio sources. This has the disadvantage that the strong correlation between radio luminosity and redshift within a single sample makes it impossible to be determine whether these differences are the result

Functional and Pangenomic Exploration of Roc Two‐Component Regulatory Systems Identifies Novel Players Across Pseudomonas Species

Molecular Microbiology, EarlyView.
The Roc system represents a highly interconnected but incomplete network of two‐component regulatory systems involved in the virulence of Pseudomonas aeruginosa. Our work has enabled us to identify the missing RocA3 regulator, to propose new players in the system and to delineate their conservation between clades of the species.

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte

Nations and Nationalism, EarlyView.
Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...

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 ...

The simplicity of physical laws

Noûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Optical- and UV-continuum Morphologies of Compact Radio Source Hosts

The Astrophysical Journal
We present the first systematic search for UV signatures from radio source-driven active galactic nuclei (AGN) feedback in Compact Steep Spectrum (CSS) radio galaxies. Owing to their characteristic sub-galactic jets (1–20 kpc projected linear sizes), CSS

The Physics of the FIR-Radio Correlation: II. Synchrotron Emission as a Star-Formation Tracer in High-Redshift Galaxies

, 2010
We construct one-zone steady-state models of cosmic ray (CR) injection, cooling, and escape over the entire dynamic range of the FIR-radio correlation (FRC), from normal galaxies to starbursts, over the redshift interval 0
