Testing the universality of the star formation efficiency in dense molecular gas
Y. Shimajiri, Ph. André, J. Braine +7
Recent studies have suggested that star formation (SF) in dense gas may be governed by essentially the same law in Galactic clouds and external galaxies. This conclusion remains co…
The [NII] 205 micron Emission in Local Luminous Infrared Galaxies
Yinghe Zhao, Nanyao Lu, C. Kevin Xu +9
In this paper, we present the measurements of the [NII] 205micron line ([NII]205) for a flux-limited sample of 122 (ultra-)luminous infrared galaxies [(U)LIRGs] and 20 additional n…
The Herschel Comprehensive (U)LIRG Emission Survey (HerCULES): CO Ladders, fine structure lines, and neutral gas cooling
M. J. F. Rosenberg, P. P. van der Werf, S. Aalto +27
(Ultra) Luminous Infrared Galaxies ((U)LIRGs) are objects characterized by their extreme infrared (8-1000 m) luminosities (L and L…
A deep search for molecular gas in two massive Lyman break galaxies at z=3 and 4: vanishing CO-emission due to low metallicity?
Qinghua Tan, Emanuele Daddi, Mark T. Sargent +14
We present deep IRAM Plateau de Bure Interferometer (PdBI) observations, searching for CO-emission toward two massive, non-lensed Lyman break galaxies (LBGs) at z=3.216 and 4.058.…
Water vapor in nearby infrared galaxies as probed by Herschel
Chentao Yang, Yu Gao, A. Omont +5
We report the first systematic study of the submillimeter water vapor rotational emission lines in infrared (IR) galaxies based on the Fourier Transform Spectrometer (FTS) data of…
A Herschel Survey of the [N II] 205 micron Line in Local Luminous Infrared Galaxies --- The [N II] 205 micron Emission as a Star Formation Rate Indicator
Yinghe Zhao, Nanyao Lu, C. Kevin Xu +16
We present, for the first time, a statistical study of [N II] 205 mciron line emission for a large sample of local luminous infrared galaxies using Herschel Spectral and Photometri…
The star formation efficiency in Stephan's Quintet intragroup regions
G. Natale, R. J. Tuffs, C. K. Xu +11
We investigated the star formation efficiency for all the dust emitting sources in Stephan's Quintet (SQ). We inferred star formation rates using Spitzer MIR/FIR and GALEX FUV data…
The dust emission SED of X-ray emitting regions in Stephan's Quintet
G. Natale, R. J. Tuffs, C. K. Xu +11
We analysed the Spitzer maps of Stephan's Quintet in order to investigate the nature of the dust emission associated with the X-ray emitting regions of the large scale intergalacti…
Molecular Gas in Infrared Ultraluminous QSO Hosts
X. Y. Xia, Y. Gao, C. -N. Hao +6
We report CO detections in 17 out of 19 infrared ultraluminous QSO (IR QSO) hosts observed with the IRAM 30m telescope. The cold molecular gas reservoir in these objects is in a ra…
Galaxy Pairs in COSMOS -- Merger Rate Evolution Since z=1
C. Kevin Xu, Yinghe Zhao, N. Scoville +3
We present results of a statistical study of the cosmic evolution of the mass dependent major-merger rate since z=1. A stellar mass limited sample of close major-merger pairs (the…
Dust emission and star formation in Stephan's Quintet
G. Natale, R. J. Tuffs, C. K. Xu +11
We analyse a comprehensive set of MIR/FIR observations of Stephan's Quintet (SQ), taken with the Spitzer Space Observatory. Our study reveals the presence of a luminous (L_{IR}\app…
Herschel observations of water vapour in Markarian 231
E. González-Alfonso, J. Fischer, K. Isaak +32
The Ultra Luminous InfraRed Galaxy Mrk 231 reveals up to seven rotational lines of water (H2O) in emission, including a very high-lying (E_{upper}=640 K) line detected at a 4sigma…
A CO(3-2) survey of a merging sequence of luminous infrared galaxies
J. Leech, K. G. Isaak, P. P. Papadopoulos +2
Luminous infrared galaxies () are often associated with interacting galactic systems and are thought to be powered by merger--induced starbursts and/…
