Proposal Title: FORMALDEHYDE EMISSION IN GALAXIES
ABSTRACT:
H 2CO megamasers are a productive area of research that was started with the Mini-Gregorian at Arecibo. Many
questions remain about the pumping and the nature of the H 2CO emission regions. Mapping studies of Arp 220
suggest extended as well as concentrated emission regions that follow the NIR emission structure. We propose three
areas of work on H 2CO sources: 1) Conrm published detections and particularly the tentative detections from
Baan et al (1993). 2. Search other superluminous FIR galaxies that are known to have OH megamaser emission but
also the OH absorption sources. 3. Enlarge the sample of nearby FIR galaxies by changing the FIR color selection
criteria used for the OH searches. In particular, search nearby spiral galaxies for weak formaldehyde emission.
