Fermi-LAT γ-ray anisotropy and intensity explained by unresolved radio-loud active galactic nuclei [PDF]

, 2014
Radio-loud active galactic nuclei (AGN) are expected to contribute substantially to both the intensity and anisotropy of the isotropic γ-ray background (IGRB).

Device Performance of Emerging Photovoltaic Materials (Version 6)

Advanced Energy Materials, EarlyView.
Efficiency of single junction perovskite (circles), organic (hexagons), dye sensitized (pentagons), kesterite (diamonds), Sb2Se3 (right triangle), and AgBiS2 (left triangles) solar cells at emerging‐pv.org over the last decade. ABSTRACT This 6th annual Emerging PV Report surveys peer‐reviewed advances since August 2024 across perovskite, organic ...

Discovery of Giant Radio Sources from TGSS Alternative Data Release 1: Radio, Optical, and Infrared Properties

The Astrophysical Journal Supplement Series
Giant radio sources (GRSs) are the single largest astrophysical objects known in the Universe that have grown to megaparsec scales (≥0.7 Mpc). GRSs are much rarer compared with normal-sized radio galaxies.

Observational Signatures of Galactic Winds Powered by Active Galactic Nuclei

, 2014
We predict the observational signatures of galaxy scale outflows powered by active galactic nuclei (AGN). Most of the emission is produced by the forward shock driven into the ambient interstellar medium (ISM) rather than by the reverse shock.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Shock heating by FR I radio sources in galaxy clusters

, 2007
Feedback by active galactic nuclei (AGN) is frequently invoked to explain the cut-off of the galaxy luminosity function at the bright end and the absence of cooling flows in galaxy clusters. Meanwhile, there are recent observations of shock fronts around

Self‐Healing Materials from Electronically Integrated Microscopic Robots

Advanced Intelligent Systems, EarlyView.
Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.

The Origin and Evolution of Giant Radio Galaxies

Frontiers in Astronomy and Space Sciences, 2022
Giant radio galaxies are arguably the least understood of jetted active galactic nuclei (AGN). We propose that radio galaxies are the product of large mergers that do not involve radio galaxies or radio quasars, such as in merging spiral galaxies, while ...

Radio Properties of Low Redshift Broad Line Active Galactic Nuclei

, 2008
The question as to whether the distribution of radio-loudness in active galactic nuclei (AGN) is actually bimodal has been discussed extensively in the literature.

New blazars from the cross-match of recent multi-frequency catalogs [PDF]

, 2014
Blazars are radio-loud active galactic nuclei well known for their non thermal emission spanning a wide range of frequencies. The Roma-BZCAT is, to date, the most comprehensive list of these sources.
