Detection of OH and wide HI absorption toward B 0218 + 357
We present deep GMRT OH and WSRT HI absorption spectra of the z = 0.6846 gravitational lens toward B0218+357. Both the 1665 MHz and 1667 MHz OH lines are clearly detected for the first time while a new wide absorption component was detected (at low significance) in the HI spectrum; the OH spectra yielded an OH column density of NOH = 2.3 × 10 cm−2. The ratio of 1667 and 1665 MHz equivalent widt...
متن کاملHi and Oh Absorption toward Ngc 6240
VLA observations of large-scale HI and OH absorption in the merging galaxy of NGC6240 are presented with 1 arcsec resolution. HI absorption is found across large areas of the extended radio continuum structure with a strong concentration towards the double-nucleus. The OH absorption is confined to the nuclear region. The HI and OH observations identify fractions of the gas disks of the two gala...
متن کاملH I and OH absorption in the lensing galaxy of MG J 0414 + 0534
We report the detection of H I 21-cm absorption in the z = 0.96 early-type lensing galaxy towards MG J0414+0534 with the Green Bank Telescope. The absorption, with total NHI = 1.6 × 10 (Ts/f) cm, is resolved into two strong components, probably due to the two strongest lens components, which are separated by 0.4. Unlike the other three lenses which have been detected in H I, J0414+0534 does not...
متن کاملDetection of Oh Absorption against Psr B1849+00
We have searched for OH absorption against seven pulsars using the Arecibo telescope. In both OH mainlines (at 1665 and 1667 MHz), deep and narrow absorption features were detected toward PSR B1849+00. In addition, we have detected several absorption and emission features against B33.6+0.1, a nearby supernova remnant (SNR). The most interesting result of this study is that a pencil-sharp absorp...
متن کاملAbsorption Line Survey of H + 3 toward the Galactic Center Sources I . GCS
We present high-resolution (R = 20000) spectroscopy of H+ 3 absorption toward the luminous Galactic center sources GCS 3-2 and GC IRS 3. With the efficient wavelength coverage afforded by Subaru IRCS, six absorption lines of H+ 3 have been detected in each source from 3.5 to 4.0μm, three of which are new. In particular the 3.543μm absorption line of the R(3,3) transition arising from the metast...
