    A semi-empirical absolute flux calibration in the near infrared: Direct stellar diameters vs. IRFM determinations
    A new semi-empirical method to derive the absolute flux calibration in the near infrared (J,K,L and L' bands) is proposed. The method consists of the...

    A Shallow Dark Matter Halo in Ultra-diffuse Galaxy AGC 242019: Are UDGs Structurally Similar to Low-surface-brightness Galaxies?
    A central question regarding ultra-diffuse galaxies (UDGs) is whether they are in a separate category from low-surface-brightness (LSB) galaxies, or just their...
