New H2O masers in Seyfert and FIR bright galaxies
Using the Effelsberg 100-m telescope, detections of four extragalactic water vapor masers are reported. Isotropic luminosities are ∼50, 1000, 1, and 230 L⊙ for Mrk 1066 (UGC 2456), Mrk 34, NGC 3556, and Arp 299, respectively. Mrk 34 contains by far the most distant and one of the most luminous water vapor megamasers so far reported in a Seyfert galaxy. The interacting system Arp 299 appears to ...
متن کاملScintillation in the Circinus Galaxy H2O megamasers
We present observations of the 22 GHz water vapor megamasers in the Circinus galaxy made with the Tidbinbilla 70 m telescope. These observations confirm the rapid variability seen earlier by Greenhill et al. (1997). We show that this rapid variability can be explained by interstellar scintillation, based on what is now known of the interstellar scintillation seen in a significant number of flat...
متن کاملExtragalactic H2O masers and X-ray absorbing column densities
Having conducted a search for the λ∼1.3 cm (22GHz) water vapor line towards galaxies with nuclear activity, large nuclear column densities or high infrared luminosities, we present H2O spectra for NGC2273, UGC5101, and NGC3393 with isotropic luminosities of 7, 1500, and 400 L⊙. The H2O maser in UGC5101 is by far the most luminous yet found in an ultraluminous infrared galaxy. NGC3393 reveals th...
متن کاملNew H 2 O masers in Seyfert and FIR bright galaxies . II . The intermediate luminosity range
Context. Recently, a relationship between the water maser detection rate and far infrared (FIR) flux density has been found as a result of a 22 GHz maser survey in a sample comprised of northern galaxies with 100 μm flux density > 50 Jy and a declination > −30. Aims. The survey has been extended toward galaxies with lower FIR flux densities in order to confirm this correlation and to discover a...
متن کاملSe p 20 01 Water Maser Emission from the Active Nucleus in M 51
22GHz water vapor ‘kilomaser’ emission is reported from the central region of the Whirlpool galaxy M51 (NGC5194). The red-shifted spectral features (VLSR∼ 560 km s ), flaring during most of the year 2000, originate from a spatially unresolved maser spot of size < ∼ 30mas (< ∼ 1.5 pc), displaced by < ∼ 250mas from the nucleus. The data provide the first direct evidence for the association of an ...
