Galaxy Zoo: Dust and molecular gas in early-type galaxies with prominent dust lanes
galaxies: ISM - galaxies: elliptical and lenticular cD - galaxies: peculiar galaxies: interactions - galaxies: formation - galaxies: evolution
2011/10/17
We study dust and associated molecular gas in 352 nearby early-type galaxies (ETGs) with prominent dust lanes. 65% of these 'dusty ETGs' (D-ETGs) are morphologically disturbed, suggesting a merger ori...
Dense Molecular Gas Excitation at High Redshift: Detection of HCO+(J=4-3) Emission in the Cloverleaf Quasar
galaxies active — galaxies starburst — galaxies formation — galaxies
2010/11/10
We report the detection of HCO+(J=4→3) emission in the Cloverleaf Quasar at z=2.56, using
the IRAM Plateau de Bure Interferometer. HCO+ emission is a star formation indicator similar
to HCN, tracing...
The Relationship Between Molecular Gas and Star Formation in Low-Mass E/S0 Galaxies
Relationship Between Molecular Gas Star Formation
2010/11/11
We consider the relationship between molecular-gas and star-formation sur-face densities in 19 morphologically defined E/S0s with stellar mass . 4 × 1010M⊙, paying particular attention to those found ...
Dense molecular gas toward W49A: A template for extragalactic starbursts?
Dense molecular gas toward W49A extragalactic starbursts
2011/1/10
The HCN, HCO+, and HNC molecules are commonly used as tracers of dense star-forming gas in external galaxies, but such observations are spatially unresolved. Reliably inferring the properties of galac...
Molecular gas properties of galaxies: The SMA CO(2-1) B0DEGA legacy project
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
In the last two decades high resolution (< 5 arcsec) CO observations for ~ 150 galaxies have provided a wealth of information about the molecular gas morphologies in the circumnuclear regions.
Dense Molecular Gas Excitation in Nuclear Starbursts at High Redshift: HCN, HNC, and HCO+(J=6-5) Emission in the z=3.91 Quasar Host of APM08279+5255
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We report the detection of surprisingly strong HCN, HNC, and HCO+(J=6-5) emission in the host galaxy of the z=3.91 quasar APM08279+5255 through observations with CARMA. HCN, HNC, and HCO+ are typicall...
