Reproduction of NGC1052-DF4 by self-interacting dark matter: dark matter deficiency and tidal features
Zhao-Chen Zhang, Xiao-Jun Bi, Peng-Fei Yin
Observations of the velocity dispersion indicate a severe dark matter (DM) deficit in the ultra-diffuse galaxy, NGC1052-DF4 (DF4). The ultra-deep images obtained with the Gemini te…

Dynamically tunable Fano resonance in periodically asymmetric graphene nanodisk pair
Zhengren Zhang, Xiaopeng Su, Yuancheng Fan +3
We present a dynamically frequency tunable Fano resonance planar device composed of periodically asymmetric graphene nanodisk pair for the mid-infrared region. There are two kinds…
