The VLA Nascent Disk and Multiplicity Survey of Perseus Protostars (VANDAM). IV. Free-Free Emission from Protostars: Links to Infrared Properties, Outflow Tracers, and Protostellar Disk Masses
Dunham, Michael M.; Kratter, Kaitlin M.; Li, Zhi-Yun +11 more
Emission from protostars at centimeter radio wavelengths has been shown to trace the free-free emission arising from ionizing shocks as a result of jets and outflows driven by protostars. Therefore, measuring properties of protostars at radio frequencies can provide valuable insights into the nature of their outflows and jets. We present a C-band …
The Herschel-PACS Legacy of Low-mass Protostars: The Properties of Warm and Hot Gas Components and Their Origin in Far-UV Illuminated Shocks
Herczeg, Gregory J.; van Dishoeck, Ewine F.; Green, Joel D. +11 more
Recent observations from Herschel allow the identification of important mechanisms responsible both for the heating of the gas that surrounds low-mass protostars and for its subsequent cooling in the far-infrared. Shocks are routinely invoked to reproduce some properties of the far-IR spectra, but standard models fail to reproduce the emission fro…
The Herschel-ATLAS Data Release 2. Paper II. Catalogs of Far-infrared and Submillimeter Sources in the Fields at the South and North Galactic Poles
Valtchanov, I.; Ivison, R. J.; de Zotti, G. +13 more
The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg2 with the PACS and SPIRE cameras in five photometric bands: 100, 160, 250, 350, and 500 µm. This is the second of three papers describing the data release for the large fields at the south and north Galactic poles (NGP and SGP). In this paper w…
The Dusty Galactic Center as Seen by SCUBA-2
Tilanus, R. P. J.; Currie, M. J.; Chrysostomou, A. +9 more
We present new JCMT SCUBA-2 observations of the Galactic Center region from 355° < l< 5° and b< +/- 1° , covering 10 × 2 square degrees along the Galactic Plane to a depth of 43 mJy beam-1 at 850 µm and 360 mJy beam-1 at 450 µm. We describe the mapping strategy and reduction method used. We present 1…
DirtyGrid I: 3D Dust Radiative Transfer Modeling of Spectral Energy Distributions of Dusty Stellar Populations
Gordon, Karl D.; Misselt, Karl A.; Law, Ka-Hei
Understanding the properties of stellar populations and interstellar dust has important implications for galaxy evolution. In normal star-forming galaxies, stars and the interstellar medium dominate the radiation from ultraviolet (UV) to infrared (IR). In particular, interstellar dust absorbs and scatters UV and optical light, re-emitting the abso…
