Dwarf barred galaxies are the perfect candidates for hosting slowly-rotating bars. They are common in dense environments and they have a relatively shallow potential well, making them prone to heating by interactions. When an interaction induces bar

The Temperature and Ionization of Unshocked Ejecta in Cas A

Autor: Raymond, J. C., Koo, B. -C., Lee, Y. -H., Milisavljevic, D., Fesen, R. A., Chilingarian, I.

The supernova remnant Cassiopeia A (Cas A) is one of the few remnants in which it is possible to observe unshocked ejecta. A deep 1.64 micron image of Cas A shows a patch of diffuse emission from unshocked ejecta, as well as brighter emission from Fa
