Beginning of ReadMe : J/ApJ/652/136 Water maser emission in five AGNs (Kondratko+, 2006) ================================================================================ Discovery of water maser emission in five AGNs and a possible correlation between water maser and nuclear 2-10 keV luminosities. Kondratko P.T., Greenhill L.J., Moran J.M. <Astrophys.

The positions of the newly discovered masers, measured with the VLA, are consistent with the optical positions of the host nuclei to within 1sigma (0.3" radio and 1.3" optical) and most likely mark the locations of the embedded central engines. The spectra of three sources, 2MASX J08362280+3327383, NGC 6264, and UGC 09618 NED02 (PGC 053432), display the characteristic spectral signature of emission from an edge-on accretion disk with maximum orbital velocity of  700,  800, and  1300km/s, respectively. We also present a GBT spectrum of a previously known source, Mrk 0034, and interpret the narrow Doppler components reported here as indirect evidence that the emission originates in an edge-on accretion disk with orbital velocity of  500km/s . Description: The survey was conducted during the 2003-2004 northern winter with the GBT using the observing system and correlator setup identical to that described in Braatz et al. (2004ApJ...617L..29B). The channel spacing was 24.4kHz and the instantaneous bandwidth was 380MHz (5600km/s for a representative recessional velocity of 12500km/s, assuming the optical definition of Doppler shift).
