The size of NGC 4151 at 11. 2 microns

Journal Article · · Astronomical Journal; (USA)

The size of the emission region of NGC 4151 at 11.2 microns has been measured to be 0.16 + or - 0.04 arcsec (1 sigma). This size is in agreement with that expected from thermal emission from dust grains heated by a central luminosity source, but is inconsistent with nonthermal emission. 19 refs.
