A search for mid-IR bands of amino acids in the Perseus Molecular Cloud
Susana Iglesias-Groth
Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, b…
A rich molecular chemistry in the gas of the IC 348 star cluster of the Perseus Molecular Cloud
Susana Iglesias-Groth, Martina Marin-Dobrincic
We present Spitzer 10-34 μm spectroscopic observations of the diffuse gas in the inner region of the star-forming region IC 348 of the Perseus Molecular Cloud. We find evidence for…
Milky Way-Like Gas Excitation in an Ultrabright Submillimeter Galaxy at
Nikolaus Sulzenauer, Helmut Dannerbauer, Anastasio Díaz-Sánchez +3
Based on observations with the IRAM 30-m and Yebes 40-m telescopes, we report evidence of the detection of Milky Way-like, low-excitation molecular gas, up to the transition CO($J=…
The Einstein ring GAL-CLUS-022058s: a Lensed Ultrabright Submillimeter Galaxy at z=1.4796
A. Díaz-Sánchez, H. Dannerbauer, N. Sulzenauer +2
We report an ultra-bright lensed submillimeter galaxy at , identified as a result of a full-sky cross-correlation of the AllWISE and Planck compact source catalogs…
A search for mid-IR bands of amino acids in the Perseus Molecular Cloud

Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, b…
Integrated molar absorptivity of mid- and far-infrared spectra of glycine and other selected amino acids
S. Iglesias-Groth, F. Cataldo
A selection of five proteinogenic amino acids, namely glycine, isoleucine, phenylalanine, tyrosine and tryptophan were studied in the mid-infrared and in the far-infrared with the…
Fullerenes in the IC 348 star cluster of the Perseus Molecular Cloud
S. Iglesias-Groth
We present the detection of fullerenes C60 and C70 in the star-forming region IC 348 of the Perseus molecular cloud. Mid-IR vibrational transitions of C60 and C70 in emission are f…
Ultra-bright CO and [CI] emission in a lensed z=2.04 submillimeter galaxy with extreme molecular gas properties
H. Dannerbauer, K. Harrington, T. Diaz-Sanchez +4
We report the very bright detection of cold molecular gas with the IRAM NOEMA interferometer of the strongly lensed source WISE J132934.18+224327.3 at z=2.04, the so-called Cosmic…
Discovery of a lensed ultrabright submillimeter galaxy at z=2.0439
A. Díaz-Sánchez, S. Iglesias-Groth, R. Rebolo +1
We report an ultra-bright lensed submillimeter galaxy (SMG) at , {\it WISE} J132934.18+224327.3, identified as a result of a full-sky cross-correlation of the {\it AllWIS…
A near/mid infrared search for ultra-bright submillimetre galaxies: Searching for Cosmic Eyelash Analogues
S. Iglesias-Groth, A. Diaz-Sanchez, R. Rebolo +1
We present results from a near/mid IR search for submillimetre galaxies over a region of 6230 sq deg. of the southern sky. We used a cross-correlation of the VISTA Hemispheric Surv…
A search for naphthalene in diffuse interstellar clouds
Susana Iglesias-Groth, Jonay I. González Hernández, Arturo Manchado
We have obtained high resolution optical spectroscopy of 10 reddened O-type stars with UVES at VLT to search for interstellar bands of the naphthalene cation (CH)…
The formation of fullerenes: clues from new C60, C70, and (possible) planar C24 detections in Magellanic Cloud Planetary Nebulae
D. A. Garcia-Hernandez, S. Iglesias-Groth, J. A. Acosta-Pulido +6
We present ten new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule. These new fullerene det…
Interstellar C_2 in the Perseus molecular complex: excitation temperature and density of a molecular cloud with anomalous microwave emission
Susana Iglesias-Groth
Interstellar absorption lines up to J"=10 in the (2,0) band and up to J"=6 in the (3,0) band of the C - system are detected toward star Cernis 52 (BD+31…
Amino Acids in Comets and Meteorites: Stability under Gamma Radiation and Preservation of Chirality
