Rapidly growing black holes and host galaxies in the distant Universe from the Herschel Radio Galaxy Evolution Project [PDF]

, 2014
We present results from a comprehensive survey of 70 radio galaxies at redshifts 1 10(12) L-circle dot) or hyper-luminous (L-tot(IR) > 10(13) L-circle dot) infrared galaxies. We fit the infrared SEDs with a set of empirical templates which represent dust

The Effect of Clear Aligners on Awareness of Tooth Clenching

Journal of Oral Rehabilitation, EarlyView.
Clear aligners do not influence perceived or EMG‐assessed clenching, while somatization emerges as a key mediator in the relationship between clenching and aligner wear. ABSTRACT Introduction Clear aligners (CAs) are an increasingly popular treatment option in modern dentistry, yet surprisingly little is known about their potential unwanted side ...

LUMINOSITY-LINEAR SIZE RELATION FOR GALAXIES AND QUASARS WITH STEEP RADIO SPECTRUM

Odessa Astronomical Publications, 2016
Our data for sources with steep radio spectrum, detected with radio telescope UTR-2 at the decametre band give evidence on the great luminosities, linear sizes, characteristic ages of these objects.

Radio continuum spectra of galaxies in the Virgo cluster region [PDF]

, 2004
New radio continuum observations of galaxies in the Virgo cluster region at 4.85, 8.6, and 10.55 GHz are presented. These observations are combined with existing measurements at 1.4 and 0.325 GHz.

Particle acceleration and dynamics of double–double radio galaxies: theory versus observations [PDF]

, 2013
In this paper we show that a small sample of radio galaxies with evidence for multiple epochs of jet activity (so-called `double-double' radio galaxies) have the same electron injection spectral index in the two activity episodes, a result which might be

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Acceleration of Ultra-high-energy Cosmic Rays in the Kiloparsec-scale Jets of Nearby Radio Galaxies

The Astrophysical Journal Letters
Radio galaxies have long been considered as potential sources of ultra-high-energy cosmic rays (UHECRs). Recent analyses of the UHECR spectrum, composition, and arrival directions indicate that the nearest radio galaxy, Centaurus A, could be linked to ...

Episodic radio galaxies J0116−4722 and J1158+2621: can we constrain the quiescent phase of nuclear activity? [PDF]

, 2013
We present multifrequency radio observations of two well known episodic FR II radio galaxies (J0116 4722 and J1158+2621) and a detailed investigation of the life-cycle of epis odic radio galaxies from their spectral and radiative properties.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Environmental Effects in Clusters: Modified Far-Infrared--Radio Relations within Virgo Cluster Galaxies [PDF]

, 2008
(abridged) We present a study on the effects of the intracluster medium (ICM) on the interstellar medium (ISM) of 10 Virgo cluster spiral galaxies using {\it Spitzer} far-infrared (FIR) and VLA radio continuum imaging.
