Variation in the dust emissivity index across M33 with Herschel and Spitzer (HerM33es)

F. S. Tabatabaei, J. Braine, E. M. Xilouris +12

We study the wavelength dependence of the dust emission as a function of position and environment across the disk of M33 at a linear resolution of 160 pc using Spitzer and Herschel…

An ALMA survey of submillimeter galaxies in the Extended Chandra Deep Field South: Source catalog and multiplicity

J. A. Hodge, A. Karim, I. Smail +24

We present an Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 0 survey of 126 submillimeter sources from the LABOCA ECDFS Submillimeter Survey (LESS). Our 870 micron surv…

Molecular Gas and Star Formation in Nearby Disk Galaxies

Adam K. Leroy, Fabian Walter, Karin Sandstrom +12

We compare molecular gas traced by 12CO(2-1) maps from the HERACLES survey, with tracers of the recent star formation rate (SFR) across 30 nearby disk galaxies. We demonstrate a fi…

The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies

K. M. Sandstrom, A. K. Leroy, F. Walter +42

We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…

An ALMA survey of Sub-millimetre Galaxies in the Extended Chandra Deep Field South: Detection of [C II] at z=4.4

Mark Swinbank, Alexander Karim, Ian Smail +19

We present ALMA 870-um (345GHz) observations of two sub-millimetre galaxies (SMGs) drawn from an ALMA study of the 126 sub-millimeter sources from the LABOCA Extended Chandra Deep…

Millimeter imaging of submillimeter galaxies in the COSMOS field: Redshift distribution

V. Smolcic, M. Aravena, F. Navarrete +21

We present new IRAM PdBI 1.3mm continuum observations at ~1.5" resolution of 28 SMGs previously discovered with the 870um bolometer LABOCA at APEX within the central 0.7deg2 of the…

The Intense Starburst HDF850.1 in a Galaxy Overdensity at z=5.2 in the Hubble Deep Field

Fabian Walter, R. Decarli, C. Carilli +24

The Hubble Deep Field (HDF) is a region in the sky that provides one of the deepest multi-wavelength views of the distant universe and has led to the detection of thousands of gala…

Giant Molecular Clouds in the Local Group Galaxy M33

P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +7

We present an analysis of the systematic CO(2-1) survey at 12" resolution covering most of the local group spiral M 33 which, at a distance of 840 kpc, is close enough that individ…

A Molecular Star Formation Law in the Atomic Gas Dominated Regime in Nearby Galaxies

Andreas Schruba, Adam K. Leroy, Fabian Walter +11

We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using atomic hydrogen (HI) data, mostly from THINGS, we predict th…

Star formation in M33 (HerM33es)

C. Kramer, M. Boquien, J. Braine +6

Within the key project "Herschel M33 extended survey" (HerM33es), we are studying the physical and chemical processes driving star formation and galactic evolution in the nearby ga…

A Constant Molecular Gas Depletion Time in Nearby Disk Galaxies

F. Bigiel, A. K. Leroy, F. Walter +8

We combine new sensitive, wide-field CO data from the HERACLES survey with ultraviolet and infrared data from GALEX and Spitzer to compare the surface densities of H2, Sigma_H2, an…

Molecular and Atomic Gas in the Local Group Galaxy M33

P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +22

We present high resolution large scale observations of the molecular and atomic gas in the Local Group Galaxy M33. The observations were carried out using the HERA at the 30m IRAM…

The Molecular Interstellar Medium of the Local Group Dwarf NGC6822

P. Gratier, J. Braine, N. J. Rodriguez-Fernandez +4

Do molecular clouds collapse to form stars at the same rate in all environments? In large spiral galaxies, the rate of transformation of H2 into stars (hereafter SFE) varies little…
