Infrared Space Observatory's Discovery of C4H2, C6H2, and Benzene in CRL 618
- J. Cernicharo, A. Heras, +4 authors L. Waters
- Physics
- 10 January 2001
We report on the detection with the Infrared Space Observatory (ISO), for the first time in the circumstellar medium, of the polyacetylenic chains C4H2 and C6H2 and of benzene (C6H6) in the direction… Expand
Atmospheric transmission at microwaves (ATM): an improved model for millimeter/submillimeter applications
- J. Pardo, J. Cernicharo, E. Serabyn
- Physics
- 1 December 2001
We present a model of the longwave atmospheric spectrum that improves in many respects widely used older models such as the microwave propagation model (MPM), since it is based on broadband… Expand
In-orbit performance of Herschel-HIFI
- P. Roelfsema, F. Helmich, +96 authors U. Yildiz
- Physics
- 2012
Aims. In this paper the calibration and in-orbit performance of the Heterodyne Instrument for the Far-Infrared (HIFI) is described. Methods. The calibration of HIFI is based on a combination of… Expand
DISCOVERY OF THE METHOXY RADICAL, CH3O, TOWARD B1: DUST GRAIN AND GAS-PHASE CHEMISTRY IN COLD DARK CLOUDS*
- J. Cernicharo, N. Marcelino, E. Roueff, M. Gerin, A. Jiménez-Escobar, G. M. M. Caro
- Chemistry
- 10 November 2012
We report on the discovery of the methoxy radical (CH3O) toward the cold and dense core B1-b based on the observation, with the IRAM 30 m radio telescope, of several lines at 3 and 2 mm wavelengths.… Expand
A λ2 mm molecular line survey of the C-star envelope IRC+10216
- J. Cernicharo, M. Gu'elin, C. Kahane
- Physics
- 1 March 2000
The mm-wave spectrum of the C-star envelope IRC+10216 has been continuously surveyed between 129.0 and 172.5 GHz with the IRAM 30-m telescope. 380 lines are detected, of which 317 have been identied.… Expand
A stubbornly large mass of cold dust in the ejecta of Supernova 1987A
- M. Matsuura, E. Dwek, +58 authors Nasa Ames Research Center
- Physics
- 26 November 2014
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 micron data and improved imaging… Expand
SPECTROSCOPIC CHARACTERIZATION AND DETECTION OF ETHYL MERCAPTAN IN ORION
- L. Kolesnikov'a, B. Tercero, +4 authors S. Shipman
- Physics
- 30 January 2014
New laboratory data of ethyl mercaptan, CH3CH2SH, in the millimeter- and submillimeter-wave domains (up to 880?GHz) provided very precise values of the spectroscopic constants that allowed the… Expand
Detection of a Noble Gas Molecular Ion, 36ArH+, in the Crab Nebula
- M. Barlow, B. Swinyard, +9 authors E. Polehampton
- Physics, Medicine
- Science
- 13 December 2013
We Are Stardust Most of the universe's chemical elements were produced in stars, with the heaviest elements being produced when stars explode. Barlow et al. (p. 1343) used the Herschel Space… Expand
Submillimeter atmospheric transmission measurements on Mauna Kea during extremely dry El Nino conditions: implications for broadband opacity contributions
- J. Pardo, E. Serabyn, J. Cernicharo
- Environmental Science
- 15 February 2001
Abstract We present broadband atmospheric transmission spectra obtained on Mauna Kea, Hawaii (4100 m. above sea level) on UT April 1st, 1998 and July 1st, 1999 under very similar pressure and… Expand
