The Evolving Interstellar Medium of Star-forming Galaxies since z = 2 as Probed by Their Infrared Spectral Energy Distributions
Daddi, E.; Elbaz, D.; Béthermin, M. +11 more
Using data from the mid-infrared to millimeter wavelengths for individual galaxies and for stacked ensembles at 0.5 < z < 2, we derive robust estimates of dust masses (M dust) for main-sequence (MS) galaxies, which obey a tight correlation between star formation rate (SFR) and stellar mass (M *), and for starbursting ga…
Herschel Far-infrared and Submillimeter Photometry for the KINGFISH Sample of nearby Galaxies
Helou, G.; Roussel, H.; Murphy, E. J. +39 more
New far-infrared and submillimeter photometry from the Herschel Space Observatory is presented for 61 nearby galaxies from the Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel (KINGFISH) sample. The spatially integrated fluxes are largely consistent with expectations based on Spitzer far-infrared photometry and extrapolations t…
GOODS-Herschel Measurements of the Dust Attenuation of Typical Star-forming Galaxies at High Redshift: Observations of Ultraviolet-selected Galaxies at z ~ 2
Magnelli, B.; Altieri, B.; Aussel, H. +20 more
We take advantage of the sensitivity and resolution of the Herschel Space Observatory at 100 and 160 µm to directly image the thermal dust emission and investigate the infrared luminosities (L IR) and dust obscuration of typical star-forming (L*) galaxies at high redshift. Our sample consists of 146 UV-selected galaxies with spect…
A Unified Empirical Model for Infrared Galaxy Counts Based on the Observed Physical Evolution of Distant Galaxies
Buat, Véronique; Daddi, Emanuele; Hezaveh, Yashar +10 more
We reproduce the mid-infrared to radio galaxy counts with a new empirical model based on our current understanding of the evolution of main-sequence (MS) and starburst (SB) galaxies. We rely on a simple spectral energy distribution (SED) library based on Herschel observations: a single SED for the MS and another one for SB, getting warmer with red…
GOODS-Herschel and CANDELS: The Morphologies of Ultraluminous Infrared Galaxies at z ~ 2
Bell, Eric F.; Dickinson, Mark; Ferguson, Henry C. +40 more
Using deep 100 and 160 µm observations in GOODS-South from GOODS-Herschel, combined with high-resolution HST/WFC3 near-infrared imaging from CANDELS, we present the first detailed morphological analysis of a complete, far-infrared (FIR) selected sample of 52 ultraluminous infrared galaxies (ULIRGs; L IR > 1012 L
A Cool Dust Factory in the Crab Nebula: A Herschel Study of the Filaments
Ivison, R. J.; Henning, Th.; Krause, O. +13 more
Whether supernovae are major sources of dust in galaxies is a long-standing debate. We present infrared and submillimeter photometry and spectroscopy from the Herschel Space Observatory of the Crab Nebula between 51 and 670 µm as part of the Mass Loss from Evolved StarS program. We compare the emission detected with Herschel with multiwavele…
The Herschel Reference Survey: Dust in Early-type Galaxies and across the Hubble Sequence
Clements, D. L.; Ciesla, L.; Bianchi, S. +24 more
We present Herschel observations of 62 early-type galaxies (ETGs), including 39 galaxies morphologically classified as S0+S0a and 23 galaxies classified as ellipticals using SPIRE at 250, 350, and 500 µm as part of the volume-limited Herschel Reference Survey (HRS). We detect dust emission in 24% of the ellipticals and 62% of the S0s. The me…
GOODS-Herschel: Impact of Active Galactic Nuclei and Star Formation Activity on Infrared Spectral Energy Distributions at High Redshift
Dickinson, Mark; Kirkpatrick, Allison; Valtchanov, Ivan +25 more
We explore the effects of active galactic nuclei (AGNs) and star formation activity on the infrared (0.3-1000 µm) spectral energy distributions (SEDs) of luminous infrared galaxies from z = 0.5 to 4.0. We have compiled a large sample of 151 galaxies selected at 24 µm (S 24 >~ 100 µJy) in the GOODS-N and ECDFS fields…
G0.253 + 0.016: A Molecular Cloud Progenitor of an Arches-like Cluster
Longmore, Steven N.; Battersby, Cara; Meingast, Stefan +20 more
Young massive clusters (YMCs) with stellar masses of 104-105 M ⊙ and core stellar densities of 104-105 stars per cubic pc are thought to be the "missing link" between open clusters and extreme extragalactic super star clusters and globular clusters. As such, studying the initial conditions of …
A Redshift Survey of Herschel Far-infrared Selected Starbursts and Implications for Obscured Star Formation
Berta, S.; Magnelli, B.; Lutz, D. +30 more
We present Keck spectroscopic observations and redshifts for a sample of 767 Herschel-SPIRE selected galaxies (HSGs) at 250, 350, and 500 µm, taken with the Keck I Low Resolution Imaging Spectrometer and the Keck II DEep Imaging Multi-Object Spectrograph. The redshift distribution of these SPIRE sources from the Herschel Multitiered Extragal…
