Extreme brightness temperatures and refractive substructure in 3C 273 with radioastron by Johnson, M., Kovalev, Y., Gwinn, C., Gurvits, L., Narayan, R., Macquart, Jean-Pierre, Jauncey, D., Voitsik, P., Anderson, J., Sokolovsky, K., Lisakov, M.

“…We also demonstrate that for a source having a Gaussian surface brightness profile, a single long-baseline estimate of refractive substructure determines an absolute minimum brightness temperature, if the scattering properties along a given line of sight are known, and that this minimum accurately approximates the apparent brightness temperature over a wide range of total flux densities.…”

OMEGA–OSIRIS mapping of emission-line galaxies in A901/2:IV. Extinction of star formation estimators with inclination by Wolf, Christian, Weinzirl, Tim, Aragón-Salamanca, Alfonso, Gray, Meghan E., Rodríguez del Pino, Bruno, Chies-Santos, Ana L., Bamford, Steven P., Böhm, Asmus, Harborne, Katherine

“…We study the effect of inclination on the apparent brightness of star-forming galaxies in spectral passbands that are commonly used as star formation indicators. …”
