Molecular gas in the Andromeda galaxy
Ch. Nieten, N. Neininger, M. Guelin +5
We present a new 12CO(J=1-0)-line survey of the Andromeda galaxy, M31, covering the bright disk with the highest resolution to date (85 pc along the major axis), observed On-the-Fl…
First detection of [CII]158um at high redshift: vigorous star formation in the early universe
R. Maiolino, P. Cox, P. Caselli +10
We report the detection of the 2P_3/2 -> 2P_1/2 fine-structure line of C+ at 157.74 micron in SDSSJ114816.64+525150.3 (hereafter J1148+5251), the most distant known quasar, at z=6.…
Multiple CO lines in SMM J16359+6612 -- Further evidence for a merger
A. Weiss, D. Downes, F. Walter +1
Using the IRAM 30m telescope, we report the detection of the CO(3--2), CO(4--3), CO(5--4) and CO(6--5) lines in the gravitational lensed submm galaxy SMM J16359+6612 at z=2.5. The…
A new intermediate mass protostar in the Cepheus A HW2 region
J. Martin-Pintado, I. Jimenez-Serra, A. Rodriguez-Franco +2
We present the discovery of the first molecular hot core associated with an intermediate mass protostar in the CepA HW2 region. The hot condensation was detected from single dish a…
Grain Evolution across the Shocks in the L1448-mm Outflow
I. Jimenez-Serra, J. Martin-Pintado, A. Rodriguez-Franco +1
The recent detection of shock-precursors toward the very young L1448-mm outflow offers us the possibility to study the grain chemistry during the first stages of the shock evolutio…
The Temperature Distribution of Dense Molecular Gas in the Center of NGC 253
Juergen Ott, Axel Weiss, Christian Henkel +1
[abridged] We present interferometric maps of ammonia (NH3) of the nearby starburst galaxy NGC 253 [star formation rate: ~2.8 Mo yr^(-1)]. The observations have been taken with the…
