Relation of internal attenuation, dust emission, and the size of spiral galaxies. Calibration at low-z and how to use it as a cosmological test at high-z

M. Lopez Corredoira, C. M. Gutierrez

Dust in spiral galaxies produces emission in the far-infrared (FIR) and internal absorption in visible wavelengths. However, the relation of the two amounts is not trivial because…
