Identification of Large-scale (>100 kpc) Radio Jets in Narrow-line Seyfert 1 Galaxies
The Astrophysical JournalPowerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-line Seyfert 1 (NLSy1) galaxies, thought to be young active galactic nuclei ...

Advanced Materials, EarlyView.Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Radio jet interactions with massive clouds
New Astronomy Reviews, 2000 Three-dimensional simulations of hydrodynamic jets are computed at rather high resolution using the ZEUS-3D code. The parameters we employ are suitable for moderate-to-high-power radio jets emerging through a galactic atmosphere or halo and eventually crossing a tilted pressure-matched interface with a hotter intracluster medium. Before they cross this

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz
Advanced Materials, EarlyView.Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

HST observations of jets and radio lobes [PDF]
Symposium - International Astronomical Union, 1996 The Hubble Space Telescope has proved to be remarkably useful for discovering and for studying the optical counterparts of radio lobes and radio jets. Since much of the structure seen in the radio is found on subarcsecond scales, it is not surprising that HST, with it's improved resolution relative to ground based observations, would be a major ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...
