Weak 13CO in the Cloverleaf Quasar: evidence for a young, early generation starburst
C. Henkel, D. Downes, A. Weiss +2
Observations of 12CO at high redshift indicate rapid metal enrichment in the nuclear regions of at least some galaxies in the early universe. However, the enrichment may be limited…
The CO line SED and atomic carbon in IRAS F10214+4724
Y. Ao, A. Weiss, D. Downes +3
Using the IRAM 30m telescope and the Plateau de Bure interferometer we have detected the \ctwo and the CO 32, 43, 65, 76 transitions as well as the dust continuum at 3…
Atomic carbon at redshift ~2.5
A. Weiss, D. Downes, C. Henkel +1
Using the IRAM 30m telescope we detected the lower fine structure line of neutral carbon towards three high--redshift sources: IRAS FSC10214 (z=2.3), SMMJ14011+0252 (z=2.5) and H14…
Gas and Dust in the Cloverleaf Quasar at Redshift 2.5
A. Weiss, C. Henkel, D. Downes +1
We observed the upper fine structure line of neutral carbon, CI(2-1), the CO(3-2) line and the 1.2mm continuum emission from H1413+117 (Cloverleaf quasar, z=2.5) using the IRAM int…
Dense gas in nearby galaxies: XV. Hot ammonia in NGC253, Maffei2 and IC342
R. Mauersberger, C. Henkel, A. Weiss +2
The detection of NH3 inversion lines up to the (J,K)=(6,6) level is reported toward the central regions of the nearby galaxies NGC253, Maffei2, and IC342. The observed lines are up…
First detection of ammonia in M82
A. Weiss, N. Neininger, C. Henkel +2
We report the detection of the (J,K) = (1,1), (2,2), and (3,3) inversion lines of ammonia (NH3) towards the south--western molecular lobe in M82. The relative intensities of the am…
