Unbiased Large Spectroscopic Surveys of Galaxies Selected by SPICA Using Dust Bands
(2017-01-01)
The mid-infrared range contains many spectral features associated with large molecules and dust grains such as polycyclic aromatic hydrocarbons and silicates. These are usually very strong compared to fine-structure gas ...
Star formation rates in luminous quasars at 2 < z < 3
(2016-02-10)
We investigate the relation between star formation rates (M˙s) and AGN properties in optically selected type 1 quasars at 2 < z < 3 using data from Herschel and the SDSS. We find that M˙s remains approximately constant ...
The role of the most luminous obscured AGNs in Galaxy assembly at Z ∼ 2
(2017-01-01)
We present Hubble Space Telescope WFC3 F160W imaging and infrared spectral energy distributions for 12 extremely luminous, obscured active galactic nuclei (AGNs) at 1.8 < z < 2.7 selected via “hot, dust-obscured” mid-infrared ...
Herus: A CO atlas from spire spectroscopy of local ULIRGs
(2016-11-01)
We present the Herschel SPIRE Fourier Transform Spectroscopy (FTS) atlas for a complete flux-limited sample of local ultraluminous infrared galaxies (ULIRGs) as part of the HERschel Ultra Luminous InfraRed Galaxy Survey ...
RADIO JET FEEDBACK and STAR FORMATION in HEAVILY OBSCURED, HYPERLUMINOUS QUASARS at REDSHIFTS ∼ 0.5-3. I. ALMA OBSERVATIONS
(2015-11-01)
We present Atacama Large Millimeter/submillimeter Array (ALMA) 870 μm (345 GHz) data for 49 high-redshift (0.47 < z < 2.85), luminous (11.7 < log(Lbol/L⊙) < 14.2) radio-powerful active galactic nuclei (AGNs), obtained to ...
Self-consistent two-phase AGN torus models : SED library for observers
(2015-11-01)
We assume that dust near active galactic nuclei (AGNs) is distributed in a torus-like geometry, which can be described as a clumpy medium or a homogeneous disk, or as a combination of the two (i.e. a two-phase medium). The ...
Unveiling the AGN in IC 883: Discovery of a parsec-scale radio jet
(2017-01-01)
IC 883 is a luminous infrared galaxy (LIRG) classified as a starburst-active galactic nucleus (AGN) composite. In a previous study, we detected a low-luminosity AGN (LLAGN) radio candidate. Here, we report on our radio ...
Star formation and AGN activity in a sample of local luminous infrared galaxies through multiwavelength characterization
(2017-01-01)
Nuclear starbursts and active galactic nucleus (AGN) activity are the main heating processes in luminous infrared galaxies (LIRGs) and their relationship is fundamental to understand galaxy evolution. In this paper, we ...
First results from GeMS/GSAOI for project SUNBIRD: Supernovae UNmasked by Infra-Red Detection
(2018-01-01)
Core collapse supernova (CCSN) rates suffer from large uncertainties as many CCSNe exploding in regions of bright background emission and significant dust extinction remain unobserved. Such a shortfall is particularly ...
Characterizing the UV-to-NIR shape of the dust attenuation curve of IR luminous galaxies up to z ~ 2
(2017-12-01)
In this work, we investigate the far-ultraviolet (UV) to near-infrared (NIR) shape of the dust attenuation curve of a sample of IR-selected dust obscured (ultra)luminous IR galaxies at z~2. The spectral energy distributions ...
