HyperFLINT: Hypernetwork‐based Flow Estimation and Temporal Interpolation for Scientific Ensemble Visualization

Computer Graphics Forum, EarlyView.
Abstract We present HyperFLINT (Hypernetwork‐based FLow estimation and temporal INTerpolation), a novel deep learning‐based approach for estimating flow fields, temporally interpolating scalar fields, and facilitating parameter space exploration in spatio‐temporal scientific ensemble data. This work addresses the critical need to explicitly incorporate

Very high-resolution radio observations of HzRGs

, 2005
We report on first results of an ongoing effort to image a small sample of high-redshift radio galaxies (HzRGs) with milliarcsecond (mas) resolution, using very-long-baseline interferometry (VLBI) techniques.

Quantifying angular clustering in wide-area radio surveys [PDF]

, 2002
We quantify the angular clustering of radio galaxies in the NVSS and FIRST radio surveys using the two-point correlation function and the moments of counts-in-cells - both important points of comparison with theory.

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.

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 ...

Exploratory Analysis of Scientific Publications for University Governance

Computer Graphics Forum, EarlyView.
This paper presents an exploratory system for the visual analysis of scientific publications for University governance. The application creates a 2D spatialisation of the publications of an institution, with an automatic clustering approach that groups papers in disciplines of research.

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 ...

Why z > 1 radio-loud galaxies are commonly located in protoclusters [PDF]

, 2014
Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in protoclusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, which preferentially reside ...

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 Seeding of Cosmic Ray Electrons by Cluster Radio Galaxies: A Review

Galaxies
Radio galaxies in clusters of galaxies are a prominent reservoir of magnetic fields and of non-thermal particles, which become mixed with the intracluster medium.
