Unveiling the remarkable photodissociation region of M8
M. Tiwari, K. M. Menten, F. Wyrowski +5
Messier 8 is one of the brightest HII regions in the sky. Using SOFIA, APEX 12 m and IRAM 30 m telescopes, we have performed a comprehensive imaging survey of the emission from the…
The diffuse molecular component in the nuclear bulge of the Milky Way
D. Riquelme, L. Bronfman, R. Mauersberger +4
Context: The bulk of the Molecular gas in the Central Molecular Zone (CMZ) of the Galactic center region shows warm kinetic temperatures, ranging from K in the coldest and de…
Physical conditions of the molecular gas in metal-poor galaxies
L. K. Hunt, A. Weiss, C. Henkel +8
Studying the molecular component of the interstellar medium in metal-poor galaxies has been challenging because of the faintness of carbon monoxide emission, the most common proxy…
DGSAT: Dwarf Galaxy Survey with Amateur Telescopes II. A catalogue of isolated nearby edge-on disk galaxies and the discovery of new low surface brightness systems
C. Henkel, B. Javanmardi, D. Martinez-Delgado +2
The connection between the bulge mass or bulge luminosity in disk galaxies and the number, spatial and phase space distribution of associated dwarf galaxies is a discriminator betw…
Molecular depletion times and the CO-to-H2 conversion factor in metal-poor galaxies
L. K. Hunt, S. Garcia-Burillo, V. Casasola +8
Tracing molecular hydrogen content with carbon monoxide in low-metallicity galaxies has been exceedingly difficult. Here we present a new effort, with IRAM 30-m observations of 12C…
On the universality of luminosity-metallicity and mass-metallicity relations for compact star-forming galaxies at redshifts 0 < z < 3
Y. I. Izotov, N. G. Guseva, K. J. Fricke +1
We study relations between global characteristics of low-redshift (0 < z < 1) compact star-forming galaxies, including absolute optical magnitudes, Hbeta emission-line luminosities…
The inhomogeneous ISM toward PKS1830-211 SW - A detailed view on molecular gas at a look-back time of 7.5 Gyr
A. Schulz, C. Henkel, K. M. Menten +4
Based on measurements with the Effelsberg 100-m telescope, a multi-line study of molecular species is presented toward the south-western source of the gravitational lens system PKS…
Dust emission in star-forming dwarf galaxies: General properties and the nature of the sub-mm excess
Y. I. Izotov, N. G. Guseva, K. J. Fricke +2
We studied the global characteristics of dust emission in a large sample of emission-line star-forming galaxies. The sample consists of two subsamples. One subsample (SDSS sample)…
The IRAM M33 CO(2-1) Survey - A complete census of the molecular gas out to 7 kpc
C. Druard, J. Braine, K. F. Schuster +11
In order to study the ISM and the interplay between the atomic and molecular components in a low-metallicity environment, we present a complete high angular and spectral resolution…
The thermal state of molecular clouds in the Galactic Center: evidence for non-photon-driven heating
Y. Ao, C. Henkel, K. M. Menten +6
We used the Atacama Pathfinder Experiment (APEX) 12 m telescope to observe the J_KaKc=3_03-2_02, 3_22-2_21, and 3_21-2_20 transitions of para-H_2CO at 218 GHz simultaneously to det…
