Observations of multiple NH transitions in W33
K. Tursun, C. Henkel, J. Esimbek +10
At a distance of 2.4kpc, W33 is an outstanding massive and luminous 10pc sized star forming complex containing quiescent infrared dark clouds as well as highly active infrared brig…
Kinetic temperature of massive star-forming molecular clumps measured with formaldehyde IV. The ALMA view of N113 and N159W in the LMC
X. D. Tang, C. Henkel, K. M. Menten +25
We mapped the kinetic temperature structure of two massive star-forming regions, N113 and N159W, in the Large Magellanic Cloud (LMC). We have used 1\hbox{$\,.\!\!^{\prime\pri…
36 GHz methanol lines from nearby galaxies: maser or quasi-thermal emission?
P. Humire, C. Henkel, Y. Gong +12
Methanol (CH3OH) is one of the most abundant interstellar molecules, offering a vast number of transitions to be studied, including many maser lines. While the strongest Galactic C…
ALMA view of the C/C isotopic ratio in starburst galaxies
X. D. Tang, C. Henkel, K. M. Menten +16
We derive molecular-gas-phase C/C isotope ratios for the central few 100 pc of the three nearby starburst galaxies NGC 253, NGC 1068, and NGC 4945 making use of the $…
Molecular line emission in NGC 4945, imaged with ALMA
C. Henkel, S. Muehle, G. Bendo +31
NGC 4945 is one of the nearest (~3.8 Mpc; 1" ~ 19 pc) starburst galaxies. ALMA band 3 (3--4\,mm) observations of HCN, HCO+, CS, C3H2, SiO, HCO, and CH3C2H were carried out with ~2"…
On carbon and oxygen isotope ratios in starburst galaxies: New data from NGC253 and Mrk231 and their implications
C. Henkel, H. Asiri, Y. Ao +9
Using the IRAM 30-m telescope, CN and CO isotopologues have been measured toward the central regions of the nearby starburst galaxy NGC253 and the prototypical ultraluminous infrar…
Ammonia in the hot core W51-IRS2: 12 new maser lines and a maser component with a velocity drift
C. Henkel, T. L. Wilson, H. Asiri +1
With the 100-m telescope at Effelsberg, 19 ammonia (NH3) maser lines have been detected toward the prominent massive star forming region W51-IRS2. Eleven of these inversion lines,…
Compact radio sources in M17
Luis F. Rodriguez, Ricardo F. Gonzalez, Gabriela Montes +3
The classic HII region M17 is one of the best studied across the electromagnetic spectrum. We present sensitive, high angular resolution observations made with the Jansky Very Larg…
