Abstract
We have measured the intensities of [S III]λλ9069, 9532 in the nucleus of the classic Liner elliptical galaxy NGC 1052. Their strength favours photoionization as opposed to shock-heating models, which is in agreement with recent [O III] electron temperature data for NGC 1052 and with [S III] data for some other Liners.Keywords
