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

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

Integrative Zoology, EarlyView.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

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

High-Redshift Radio Galaxies [PDF]

Highlights of Astronomy, 1995
Radio galaxies are unique cosmological probes. As with radio-loud quasars, the presence of luminous radio continuum and optical line emission enable radio galaxies to be observed and recognized at large distances, up to z = 4.2. However, unlike the situation for most quasars, their optical emission can be spatially resolved from the ground and studied ...

Deep Learning for Detecting Dental Plaque and Gingivitis From Oral Photographs: A Systematic Review

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives This systematic review aimed to evaluate the performance of deep learning (DL) models in detecting dental plaque and gingivitis from red, green, and blue (RGB) intraoral photographs. Methods A comprehensive literature search was conducted across Medline, Scopus, Embase, and Web of Science databases up to January 31, 2025.

Starburst radio galaxies: general properties, evolutionary histories and triggering [PDF]

, 2010
In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the activity and the evolution of the host galaxies.

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.

Towards Scaling‐Invariant Projections for Data Visualization

Computer Graphics Forum, EarlyView.
Abstract Finding projections of multidimensional data domains to the 2D screen space is a well‐known problem. Multidimensional data often comes with the property that the dimensions are measured in different physical units, which renders the ratio between dimensions, i.e., their scale, arbitrary.

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 ...

Clusters of galaxies in radio

, 2003
Recent results on the radio emission from galaxy clusters are reviewed, with emphasis both on the radio galaxies and on the diffuse radio emission from the intracluster medium. We show that the formation of the tailed morphology in cluster radio galaxies is due to the effect of the cluster gaseous environment and of its large scale motions in merging ...
