Dust Attenuation Curves in the Local Universe: Demographics and New Laws for Star-forming Galaxies and High-redshift Analogs
Boquien, Médéric; Salim, Samir; Lee, Janice C.
We study the dust attenuation curves of 230,000 individual galaxies in the local universe, ranging from quiescent to intensely star-forming systems, using GALEX, SDSS, and WISE photometry calibrated on the Herschel ATLAS. We use a new method of constraining SED fits with infrared luminosity (SED+LIR fitting), and parameterized attenuation curves d…
The HDUV Survey: A Revised Assessment of the Relationship between UV Slope and Dust Attenuation for High-redshift Galaxies
van Dokkum, Pieter G.; Illingworth, Garth D.; Labbé, Ivo +13 more
We use a newly assembled sample of 3545 star-forming galaxies with secure spectroscopic, grism, and photometric redshifts at z = 1.5-2.5 to constrain the relationship between UV slope (β) and dust attenuation (L IR/L UV ≡ IRX). Our sample significantly extends the range of L UV and β probed in previous UV-selected …
“Super-deblended” Dust Emission in Galaxies. II. Far-IR to (Sub)millimeter Photometry and High-redshift Galaxy Candidates in the Full COSMOS Field
Calabrò, Antonello; Dickinson, Mark; Daddi, Emanuele +17 more
We present a “super-deblended” far-infrared (FIR) to (sub)millimeter photometric catalog in the Cosmic Evolution Survey (COSMOS), prepared with the method recently developed by Liu et al., with key adaptations. We obtain point-spread function fitting photometry at fixed prior positions including 88,008 galaxies detected in VLA 1.4, 3 GHz, and/or M…
“Super-deblended” Dust Emission in Galaxies. I. The GOODS-North Catalog and the Cosmic Star Formation Rate Density out to Redshift 6
Dickinson, Mark; Inami, Hanae; Daddi, Emanuele +10 more
We present a new technique to measure multi-wavelength “super-deblended” photometry from highly confused images, which we apply to Herschel and ground-based far-infrared (FIR) and (sub-)millimeter (mm) data in the northern field of the Great Observatories Origins Deep Survey. There are two key novelties. First, starting with a large database of de…
The Brightest Galaxies in the Dark Ages: Galaxies’ Dust Continuum Emission during the Reionization Era
Finkelstein, Steven L.; Casey, Caitlin M.; Zavala, Jorge A. +6 more
Though half of cosmic starlight is absorbed by dust and reradiated at long wavelengths (3 µm-3 mm), constraints on the infrared through the millimeter galaxy luminosity function (or the “IRLF”) are poor in comparison to the rest-frame ultraviolet and optical galaxy luminosity functions, particularly at z ≳ 2.5. Here, we present a backward ev…
A Survey of Atomic Carbon [C I] in High-redshift Main-sequence Galaxies
Dickinson, Mark E.; Lee, Min-Young; Daddi, Emanuele +15 more
We present the first results of an Atacama Large Millimeter Array survey of the lower fine-structure line of atomic carbon [C I] {(}3{P}1 {--}{}3{P}0) in far-infrared-selected galaxies on the main sequence at z ∼ 1.2 in the COSMOS field. We compare our sample with a comprehensive compilation of data avai…
SHINING, A Survey of Far-infrared Lines in Nearby Galaxies. II. Line-deficit Models, AGN Impact, [C II]-SFR Scaling Relations, and Mass-Metallicity Relation in (U)LIRGs
Lutz, D.; Genzel, R.; Maiolino, R. +12 more
The SHINING survey offers a great opportunity to study the properties of the ionized and neutral media of galaxies from prototypical starbursts and active galactic nuclei (AGNs) to heavily obscured objects. Based on Herschel/PACS observations of the main far-infrared (FIR) fine-structure lines, in this paper, we analyze the physical mechanisms beh…
On the Gas Content and Efficiency of AGN Feedback in Low-redshift Quasars
Ho, Luis C.; Shangguan, Jinyi; Xie, Yanxia
The interstellar medium is crucial to understanding the physics of active galaxies and the coevolution between supermassive black holes and their host galaxies. However, direct gas measurements are limited by sensitivity and other uncertainties. Dust provides an efficient indirect probe of the total gas. We apply this technique to a large sample o…
SHINING, A Survey of Far-infrared Lines in Nearby Galaxies. I. Survey Description, Observational Trends, and Line Diagnostics
Lutz, D.; Genzel, R.; Maiolino, R. +12 more
We use the Herschel/PACS spectrometer to study the global and spatially resolved far-infrared (FIR) fine-structure line emission in a sample of 52 galaxies that constitute the SHINING survey. These galaxies include star-forming, active-galactic nuclei (AGNs), and luminous infrared galaxies (LIRGs). We find an increasing number of galaxies (and kil…
Gaia 17bpi: An FU Ori-type Outburst
Naylor, Tim; Mainzer, Amy K.; Hillenbrand, Lynne A. +7 more
We report on the source Gaia 17bpi and identify it as a new, ongoing FU Ori-type outburst, associated with a young stellar object. The optical light curve from Gaia exhibited a 3.5 mag rise with the source appearing to plateau in mid-/late 2018. Mid-infrared observations from NEOWISE also show a >3 mag rise that occurred in two stages, with the…
