Submillimeter water and ammonia absorption by the peculiar z~0.89 interstellar medium in the gravitational lens of the PKS 1830-211 system
K. M. Menten, R. Guesten, S. Leurini +5
Using the Atacama Pathfinder Experiment (APEX) telescope we have detected the rotational ground-state transitions of ortho-ammonia and ortho-water toward the redshift ~0.89 absorbi…
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…
Detection of 6.7 GHz methanol absorption towards hot corinos
J. D. Pandian, S. Leurini, K. M. Menten +2
Methanol masers at 6.7 GHz have been found exclusively towards high-mass star forming regions. Recently, some Class 0 protostars have been found to display conditions similar to wh…
Variations of the Radio Synchrotron Spectral Index in M33
F. S. Tabatabaei, R. Beck, E. Krügel +4
We determine the variation in the nonthermal radio spectral index in the nearby spiral galaxy M33. We separate the thermal and nonthermal components of the radio continuum emission…
ATCA 3mm observations of NGC6334I and I(N): dense cores, outflows and an UCHII region
H. Beuther, A. J. Walsh, S. Thorwirth +4
Aims: Investigation of the dense gas, the outflows and the continuum emission from the massive twin cores NGC6334I and I(N) at high spatial resolution. Methods: We imaged the regio…
Interacting coronae of two T Tauri stars: first observational evidence for solar-like helmet streamers
M. Massi, E. Ros, K. M. Menten +7
Context {The young binary system V773 Tau A exhibits a persistent radio flaring activity that gradually increases from a level of a few mJy at apoastron to more than 100 mJy at per…
