The first detection of SiC in the interstellar medium
S. Massalkhi, I. Jiménez-Serra, J. Martín-Pintado +7
We report the first detection of SiC in the interstellar medium. The molecule was identified through six rotational transitions toward G\,+0.6930.027, a molecular cloud loca…
H2CN/H2NC abundance ratio: a new potential temperature tracer for the interstellar medium
David San Andrés, Laura Colzi, Víctor M. Rivilla +7
The radical is the high-energy metastable isomer of radical, which has been recently detected for the first time in the interstellar medium towards a ha…
Amides inventory towards the G+0.693-0.027 molecular cloud
S. Zeng, V. M. Rivilla, I. Jiménez-Serra +6
Interstellar amides have attracted significant attentions as they are potential precursors for a wide variety of organics essential to life. However, our current understanding of t…
MASCOT -- An ESO-ARO legacy survey of molecular gas in nearby SDSS-MaNGA galaxies: I. first data release, and global and resolved relations between H_2 and stellar content
D. Wylezalek, C. Cicone, F. Belfiore +11
We present the first data release of the MaNGA-ARO Survey of CO Targets (MASCOT), an ESO Public Spectroscopic Survey conducted at the Arizona Radio Observatory (ARO). We measure th…
First detection of CHNCO in the ISM and search of other isocyanates towards the G+0.693-0.027 molecular cloud
L. F. Rodríguez Almeida, V. M. Rivilla, I. Jiménez-Serra +9
Little is known about the chemistry of isocyanates (compounds with the functional group R-N=C=O) in the interstellar medium, as only four of them have been detected so far: isocyan…
Detection of the cyanomidyl radical (HNCN): a new interstellar species with the NCN backbone
V. M. Rivilla, I. Jiménez-Serra, J. García de la Concepción +9
We report here the first detection in the interstellar medium of the cyanomidyl radical (HNCN). Using the Yebes 40m and the IRAM 30m telescopes, we have targeted the doublets of th…
Observation of inverse Compton emission from a long -ray burst
V. A. Acciari, S. Ansoldi, L. A. Antonelli +301
Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…
Detection of deuterated molecules, but not of lithium hydride, in the z=0.89 absorber toward PKS1830-211
S. Muller, E. Roueff, J. H. Black +8
Deuterium and lithium are light elements of high cosmological and astrophysical importance. In this work we report the first detection of deuterated molecules and a search for lith…
Systematic Variations of CO J=2-1/1-0 Ratio in The Barred Spiral Galaxy M83
J. Koda, T. Sawada, K. Sakamoto +18
We present spatial variations of the CO J=2-1/1-0 line ratio in M83 using Total Power array data from ALMA. While the intensities of these two lines correlate tightly, the ratio va…
Disentangling the Circumnuclear Environs of Centaurus A: III. An Inner Molecular Ring, Nuclear Shocks and the CO to warm H2 interface
D. Espada, S. Matsushita, R. E. Miura +11
We present the distribution and kinematics of the molecular gas in the circumnuclear disk (CND, 400 pc x 200 pc) of Centaurus A with resolutions of ~5 pc (0.3 arcsec) and shed ligh…
Detection of chloronium and measurement of the 35Cl/37Cl isotopic ratio at z=0.89 toward PKS1830-211
S. Muller, J. H. Black, M. Guelin +11
We report the first extragalactic detection of chloronium (H2Cl+), in the z=0.89 absorber in front of the lensed blazar PKS1830-211. The ion is detected through its 1_11-0_00 line…
An ALMA Early Science survey of molecular absorption lines toward PKS1830-211 -- Analysis of the absorption profiles
S. Muller, F. Combes, M. Guelin +17
We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z=0.89 molecular absorber toward the lensed blazar PKS1830…
Mapping photodissociation and shocks in the vicinity of Sgr A*
M. A. Amo-Baladrón, J. Martín-Pintado, S. Martín
We have obtained maps of the molecular emission within the central five arcminutes (12 pc) of the Galactic center (GC) in selected molecular tracers: SiO(2-1), HNCO(5_{0,5}-4_{0,4}…
Unveiling the main heating sources in the Cepheus A HW2 region
I. Jimenez-Serra, J. Martin-Pintado, P. Caselli +4
We present high angular resolution PdBI images (beam of ~0.33'') of the J=27-26 line from several vibrational levels (v7=1 and v6=1) of HC3N toward Cepheus A HW2. These images reve…
