摘要: We present Expanded Very Large Array and Arecibo observations of two lensed submm galaxies at z~2.5, in order to search for redshifted 22.235 GHz water megamaser emission. Both SMM J14011+0252 J16359+6612 have multi-wavelength characteristics consistent with ongoing starburst activity, as well CO line emission indicating the presence warm molecular gas. Our do not reveal any evidence H2O either target, while lensing allows us obtain deep limits H_2O luminosities, L(H2O) < 7470 Lsun (3-sigma) case J14011+0252, 1893 J16359+6612, assuming linewidths 80 km/s. for, subsequent non-detection strongly galaxies, rich gas dust, suggests that such is likely be common within unlensed population high-redshift galaxies. use recent detection strong quasar, MG J0414+0534 z = 2.64 make predictions future EVLA C-band surveys hosting AGN.
