    Study on the Effect of Surface Roughness on the Spectral Unmixing of Mixed Pixels by Haonan Zhang, Xingping Wen, Junlong Xu, Dayou Luo, Ping He

    Published 2020-01-01
    “…If the surface roughness of the sample to be measured is less than the maximum wavelength of the spectrometer, the experimental results believe that the photon energy is mainly mirror reflection on the surface of the object and diffuse reflection. At this time, it is still a better choice to use a linear spectral mixing model to decompose the mixed pixels.…”

    HCG 57: Evidence for Shock-heated Intergalactic Gas from X-Rays and Optical Emission Line Spectroscopy by Ewan O’Sullivan, P. N. Appleton, B. A. Joshi, Lauranne Lanz, Katherine Alatalo, Jan M. Vrtilek, Andreas Zezas, Laurence P. David

    Published 2025-01-01
    “…These different shock velocities can be reconciled by considering the contributions of rotation to collision velocity in different parts of the disks, and the clumpy nature of the preshock medium in the galaxies, which likely lead to different shock velocities in different components of the turbulent postshocked gas. We examine the diffuse X-ray emission in the group members and their associated point sources, identifying X-ray active galactic nuclei in HCG 57A, B, and D. …”
