Title: | On the low detection efficiency of disk water megamasers in Seyfert 2 AGN | Authors: | Masini, Alberto COMASTRI, Andrea |
Issue Date: | 2018 | Volume: | Astrophysical Masers: Unlocking the Mysteries of the Universe | Editors: | Tarchi, A.; Reid, M. J.; Castangia, P. | Series: | PROCEEDINGS OF THE INTERNATIONAL ASTRONOMICAL UNION | Number: | 336 | First Page: | 133 | Abstract: | Disk megamasers are a unique tool to study active galactic nuclei (AGN) sub-pc environment, and precisely measure some of their fundamental parameters. While the majority of disk megamasers are hosted in heavily obscured (i.e., Seyfert 2, Sy2) AGN, the converse is not true, and disk megamasers are very rarely found even in obscured AGN. The very low detection rate of such systems in Sy2 AGN could be due to the geometry of the maser beaming, which requires a strict edge-on condition. We explore some other fundamental factors which could play a role in a volume-limited survey of disk megamasers in Sy2 galaxies, most importantly the radio luminosity. | Conference Name: | Astrophysical Masers: Unlocking the Mysteries of the Universe | Conference Place: | Cagliari, Italia | Conference Date: | 4-8 Settembre, 2017 | URI: | http://hdl.handle.net/20.500.12386/27694 | URL: | https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/on-the-low-detection-efficiency-of-disk-water-megamasers-in-seyfert-2-agn/9C937FB21D6BFB66E8C77CF668EA14E9 | ISSN: | 1743-9213 | ISBN: | 978-1107192454 | DOI: | 10.1017/S1743921317009383 | Bibcode ADS: | 2018IAUS..336..133M | Fulltext: | open |
