The ALPINE-ALMA [CII] survey. The nature, luminosity function, and star formation history of dusty galaxies up to z ≃ 6
Cimatti, A.; Pozzi, F.; Rodighiero, G. +30 more
Aims: We present the detailed characterisation of a sample of 56 sources serendipitously detected in ALMA band 7 as part of the ALMA Large Program to INvestigate CII at Early Times (ALPINE). These sources, detected in COSMOS and ECDFS, have been used to derive the total infrared luminosity function (LF) and to estimate the cosmic star formati…
Tracing the total molecular gas in galaxies: [CII] and the CO-dark gas
Ramambason, L.; Lebouteiller, V.; Madden, S. C. +11 more
Context. Molecular gas is a necessary fuel for star formation. The CO (1-0) transition is often used to deduce the total molecular hydrogen but is challenging to detect in low-metallicity galaxies in spite of the star formation taking place. In contrast, the [C II]λ158 µm is relatively bright, highlighting a potentially important reservoir o…
Molecular outflows in local galaxies: Method comparison and a role of intermittent AGN driving
Lutz, D.; Genzel, R.; Maiolino, R. +19 more
We report new detections and limits from a NOEMA and ALMA CO(1-0) search for molecular outflows in 13 local galaxies with high far-infrared surface brightness, and combine these with local universe CO outflow results from the literature. The CO line ratios and spatial outflow structure of our targets provide some constraints on the conversion step…
Galactic cirri in deep optical imaging
Trujillo, Ignacio; Román, Javier; Montes, Mireia
The ubiquitous presence of Galactic cirri in deep optical images represents a major obstacle to study the low surface brightness features of extragalactic sources. To address this issue, we have explored the optical properties of cirri using g, r, i, and z bands in the Sloan Digital Sky Survey (SDSS) Stripe82 region. Using state-of-the-art, custom…
Properties of the dense core population in Orion B as seen by the Herschel Gould Belt survey
White, G. J.; André, Ph.; Arzoumanian, D. +15 more
We present a detailed study of the Orion B molecular cloud complex (d ~ 400 pc), which was imaged with the PACS and SPIRE photometric cameras at wavelengths from 70 to 500 µm as part of the Herschel Gould Belt survey (HGBS). We release new high-resolution maps of column density and dust temperature for the whole complex, derived in the same …
The Herschel view of the dense core population in the Ophiuchus molecular cloud
André, Ph.; Arzoumanian, D.; Könyves, V. +15 more
Context. Herschel observations of nearby clouds in the Gould Belt support a paradigm for low-mass star formation, starting with the generation of molecular filaments, followed by filament fragmentation, and the concentration of mass into self-gravitating prestellar cores. In the case of the Ophiuchus molecular complex, a rich star formation activi…
The ISM scaling relations in DustPedia late-type galaxies: A benchmark study for the Local Universe
Bianchi, S.; Fritz, J.; Madden, S. C. +18 more
Aims: The purpose of this work is the characterization of the main scaling relations between all of the interstellar medium (ISM) components, namely dust, atomic, molecular, and total gas, and gas-phase metallicity, as well as other galaxy properties, such as stellar mass (Mstar) and galaxy morphology, for late-type galaxies in the…
In pursuit of giants. I. The evolution of the dust-to-stellar mass ratio in distant dusty galaxies
Gómez-Guijarro, C.; Małek, K.; Feltre, A. +11 more
The dust-to-stellar mass ratio (Mdust/M⋆) is a crucial, albeit poorly constrained, parameter for improving our understanding of the complex physical processes involved in the production of dust, metals, and stars in galaxy evolution. In this work, we explore trends of Mdust/M⋆ with different physical par…
GOODS-ALMA: The slow downfall of star formation in z = 2-3 massive galaxies
Magnelli, B.; Daddi, E.; Elbaz, D. +34 more
We investigate the properties of a sample of 35 galaxies, detected with the Atacama Large Millimeter/Submillimeter Array (ALMA) at 1.1 mm in the GOODS-ALMA field (area of 69 arcmin2, resolution = 0.60″, rms ≃ 0.18 mJy beam-1). Using the ultraviolet-to-radio deep multiwavelength coverage of the GOODS-South field, we fit the sp…
A 3D view of the Taurus star-forming region by Gaia and Herschel. Multiple populations related to the filamentary molecular cloud
Franciosini, E.; Randich, S.; Sicilia-Aguilar, A. +2 more
Context. Taurus represents an ideal region to study the three-dimensional distribution of the young stellar population and relate it to the associated molecular cloud.
Aims: The second Gaia data release (DR2) enables us to investigate the Taurus complex in three dimensions, starting from a previously defined robust membership. The molecular c…
