Probing the mass loss history of the yellow hypergiant IRC+10420 (2009)
Muller, Sebastien, Lim, Jeremy, Kwok, Sun, Muthu, C.
We have used the sub-millimeter array to image the molecular envelope around IRC+10420. Our observations reveal a large and clumpy expanding envelope around the star. The molecular envelope shows a...
HCO+ and HCN J=3-2 absorption toward the center of Centaurus A (2009)
We have investigated the presence of dense gas toward the radio source Cen A by looking at the absorption of the HCO+ and HCN (3-2) lines in front of the bright continuum source with the...

Based on measurements with the Effelsberg 100-m telescope, a multi-line study of molecular species is presented toward the gravitational lens system PKS 1830–211, which is by far the best known...

SMA CO(J=6-5) and 435 micron interferometric imaging of the nuclear region of Arp 220 (2008)
Matsushita, Satoki, Iono, Daisuke, Petitpas, Glen R., Chou, Richard C. -Y., Gurwell, Mark A., Hunter, Todd R., ...
We have used the Submillimeter Array (SMA) to make the first interferometric observations (beam size ~1") of the 12CO J=6-5 line and 435 micron (690 GHz) continuum emission toward the central region...
Drastic changes in the molecular absorption at redshift z=0.89 toward the quasar PKS 1830-211 (2008)
Muller, Sebastien, Guelin, Michel
A 12 year-long monitoring of the absorption caused by a z=0.89 spiral galaxy on the line of sight to the radio-loud gravitationally lensed quasar PKS 1830-211 reveals spectacular changes in the HCO+...

The Standard Model of particle physics assumes that the so-called fundamental constants are universal and unchanging. Absorption lines arising in molecular clouds along quasar sightlines offer a...
Searching for dust in the intracluster medium from reddening of background galaxies (2008)
Muller, Sebastien, Wu, Szu-Ying, Hsieh, Bau-Ching, Gonzalez, Rosa, Loinard, Laurent, Yee, Howard, ...
We report a search for the presence of dust in the intra-cluster medium based on the study of statistical reddening of background galaxies. Armed with the Red Sequence Cluster survey data, from which...

Jet-disturbed molecular gas near the Seyfert 2 nucleus in M51 (2007)
Matsushita, Satoki, Muller, Sebastien, Lim, Jeremy
Previous molecular gas observations at arcsecond-scale resolution of the Seyfert 2 galaxy M51 suggest the presence of a dense circumnuclear rotating disk, which may be the reservoir for fueling the...
Muller, Sebastien, Guelin, Michel, Dumke, Michael, Lucas, Robert, Combes, Francoise
With the Plateau de Bure interferometer, we have measured the C, N, O and S isotopic abundance ratios in the arm of a spiral galaxy with a redshift of 0.89. The galaxy is seen face-on according to...
Total Opacity of Local Group Galaxies and Large Scale Structure behind the Galactic Bulge (2004)
Gonzalez, Rosa A., Holwerda, Benne, Loinard, Laurent, Allen, Ronald J., Muller, Sebastien
Recently, we have developed and calibrated the Synthetic Field Method to derive total extinction through disk galaxies. The method is based on the number counts and colors of distant background field...
