The emission structure of formaldehyde megamasers [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The formaldehyde MegaMaser emission has been mapped for the three host galaxies IC\,860. IRAS\,15107$+$0724, and Arp\,220. Elongated emission components are found at the nuclear centres of all galaxies with an extent ranging between 30 to 100 pc. These components are superposed on the peaks of the nuclear continuum.

Thermal formaldehyde emission in NGC 7538 IRS 1 [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Spectral lines from formaldehyde (H2CO) molecules at cm wavelengths are typically detected in absorption and trace a broad range of environments, from diffuse gas to giant molecular clouds. In contrast, thermal emission of formaldehyde lines at cm wavelengths is rare. In previous observations with the 100 m Robert C.

The influence of decorative surface of commercial particleboards on the formaldehyde release measured by flask method [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2018 The formaldehyde release and the formaldehyde content from the commercial particleboards were determined using the flask and perforator methods. Since the melamine faced boards were used in this research, the flask method was applied to evaluate

Formaldehyde emission in galaxies
The Astrophysical Journal, 1993 Nine detections of extragalactic emission in the 4.83 GHz 1 10 -1 11 formaldehyde transition are presented in addition to the only previously known extragalactic emission source in IC 4553. Formaldehyde emission occurs among both OH absorbers and emitters. In contrast with the high-detection rate of extragalactic sources in this survey, there are only
