J/AJ/124/100        OH megamasers at z>0.1. III              (Darling+, 2002)

A search for OH megamasers at z>0.1. III. The complete survey. Darling J., Giovanelli R. <Astron. J. 124, 100 (2002)> =2002AJ....124..100D
ADC_Keywords: Masers ; Infrared sources ; Radio sources ; Surveys Keywords: galaxies: evolution - galaxies: interactions - galaxies: star clusters - infrared radiation - radio emission lines Abstract: We present the final results from the Arecibo Observatory OH megamaser survey. We discuss in detail the properties of the remaining 18 OH megamasers detected in the survey, including three redetections. We place upper limits on the OH emission from 85 nondetections and examine the properties of 25 ambiguous cases for which the presence or absence of OH emission could not be determined. The complete survey has discovered 50 new OH megamasers (OHMs) in (ultra)luminous infrared galaxies ([U]LIRGs), which doubles the sample of known OHMs and increases the sample at z>0.1 sevenfold.

Note (1): This marginal OH detection (3.4σ; Dickey et al., 1990AJ....100.1457D) was undetectable at Arecibo because of standing waves produced by its strong continuum. Note (2): If no continuum source lies within 30" of the IRAS coordinates, an upper limit of 5.0mJy is listed. Note (3): Spectral classifications as follows: S1 = Seyfert type 1 S2 = Seyfert type 2 H = HII region (starburst) L = low-ionization emission region (LINER)
