The Parsec-Scale Structure Of The Newer Tev Blazars, Glenn Piner
The Parsec-Scale Structure Of The Newer Tev Blazars, Glenn Piner
Physics
We expand our previous studies of the parsec-scale structure of TeV blazars by presenting first- epoch images from VLBA monitoring of ten newer TeV HBLs. All ten sources were successfully detected and imaged, and all showed a one-sided core-jet structure. Many display a morphology common to TeV HBLs: a short, collimated jet followed by a transition to low surface brightness extended emission with a much broader opening angle. The newly detected TeV HBLs tend to be fainter in the radio; the median core flux density was 22 mJy, and the median brightness temperature was 8 × 109 K. The brightness …

Magnetic Tuning Of Plasmonic Excitation Of Gold Nanorods, Serkan Zorba, Mingsheng Wang, Chuanbo Gao, Le He, Jinzhong Zhang, Chi Tang, Yadong Yin
Physics
By using gold nanorods as an example, we report the dynamic and reversible tuning of the plasmonic property of anisotropically shaped colloidal metal nanostructures by controlling their orientation using external magnetic fields. The magnetic orientational control enables instant and selective excitation of the plasmon modes of AuNRs through the manipulation of the field direction relative to the directions of incidence and polarization of light.
