To date, 204 individual molecular species, comprised of 16 different elements, have been detected in the interstellar and circumstellar medium by astronomical observations. These molecules range in size from two atoms to seventy, and have been detected across the electromagnetic spectrum from cm-wavelengths to the ultraviolet. This census presents a summary of the first detection of each molecular species, including the observational facility, wavelength range, transitions, and enabling… Expand
Laboratory data in support of JWST observations of interstellar ices
Abstract Experimental and theoretical studies have shown that Complex Organic Molecules (COMs) can be formed on icy dusty grains in molecular clouds and protoplanetary disks. The number ofExpand
Galactic and Extragalactic Astrochemistry : Heavy-Molecule Precursors to Life ?
  • 2019
Heavy molecule spectroscopy is a developing subject, with new results from both the terrestrial laboratory and astronomical discovery in the 0.5-10 GHz range where heavy molecule spectral lines areExpand

Abstract The search for complex organic molecules in the interstellar medium (ISM) has revealed species of ever greater complexity. This search relies on the progress made in the laboratory toExpand
Volatile depletion in planet-forming disks
Newly born stars are surrounded by gas and dust with a flattened axisymmetric distribution termed protoplanetary disk, in which planets are formed. Observations of these objects are necessary forExpand
An Unbiased ALMA Spectral Survey of the LkCa 15 and MWC 480 Protoplanetary Disks
The volatile contents of protoplanetary disks both set the potential for planetary chemistry and provide valuable probes of defining disk system characteristics such as stellar mass, gas mass,Expand
λ = 2 mm spectroscopy observations toward the circumnuclear disk of NGC 1068
Aims. We investigate the physical and chemical conditions of molecular gas in the circumnuclear disk (CND) region of NGC 1068. Methods. We carried out a spectral line survey with the IRAM 30mExpand
Searches for Interstellar HCCSH and H2CCS
A long standing problem in astrochemistry is the inability of many current models to account for missing sulfur content. Many relatively simple species that may be good candidates to sequester sulfurExpand
Submillimeter-wave spectroscopy and the radio-astronomical investigation of propynethial (HC≡CCHS)
Context. The majority of sulfur-containing molecules detected in the interstellar medium (ISM) are analogs of oxygen-containing compounds. Propynal was detected in the ISM in 1988, henceExpand
An investigation of spectral line stacking techniques and application to the detection of HC11N
As the inventory of interstellar molecules continues to grow, the gulf between small species, whose individual rotational lines can be observed with radio telescopes, and large ones, such asExpand
Submillimeter and Far-infrared Spectroscopy of Monodeuterated Amidogen Radical (NHD): Improved Rest Frequencies for Astrophysical Observations
Observations of ammonia in interstellar environments have revealed high levels of deuteration, and all its D-containing variants, including ND$_3$, have been detected in cold prestellar cores andExpand


First detections of extragalactic SO2, NS and NO
We report the first detections of SO 2 , NS and NO in an extragalactic source, the nucleus of the starburst galaxy NGC 253. Five SO 2 transitions, three groups of hyperfine components of NO and fiveExpand
Detection of Interstellar OH in Two External Galaxies
Abstract : Molecular OH lines at 1665 and 1667 MHz have been detected in absorption in the spiral galaxy NGC 253 and the irregular galaxy M82. This is the first time interstellar molecular lines,Expand
Detection of an Extrasolar Planet Atmosphere
We report high-precision spectrophotometric observations of four planetary transits of HD 209458, in the region of the sodium resonance doublet at 589.3 nm. We find that the photometric dimmingExpand
Detection of Interstellar PN: The First Identified Phosphorus Compound in the Interstellar Medium
Interstellar PN has been identified in Ori (KL), W51M, and Sgr B2, by observations of its J = 2-1, 3-2, and 5-4 rotational transitions. PN appears to occur in regions of relatively high excitation,Expand
First Detection of the Simplest Organic Acid in a Protoplanetary Disk
The formation of asteroids, comets, and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of the disk might shapeExpand
Observations of the Icy Universe
Freeze-out of the gas-phase elements onto cold grains in dense interstellar and circumstellar media builds up ice mantles consisting of molecules that are mostly formed in situ (H2O, NH3, CO2, CO,Expand
Detection of CH 4 in the GV Tau N Protoplanetary Disk
T Tauri stars are low mass young stars that may serve as analogs to the early solar system. Observations of organic molecules in the protoplanetary disks surrounding T Tauri stars are important forExpand
Detection of C60 and C70 in a Young Planetary Nebula
The environment of Tc 1, a peculiar planetary nebula whose infrared spectrum shows emission from cold and neutral C60 and C70, is studied, indicating that if the conditions are right, fullerenes can and do form efficiently in space. Expand
Detection of extragalactic argonium, ArH + , toward PKS 1830-211
Context. Argonium has recently been detected as a ubiquitous molecule in our Galaxy. Model calculations indicate that its abundance peaks at molecular fractions in the range of 10^(-4) to 10^(-3) andExpand
