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 ...
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 ...
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 ...
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 ...
The concept of ageing in evolutionary algorithms: Discussion and inspirations for human ageing
(2017-04-01)
This paper discusses the concept of ageing as this applies to the operation of Evolutionary Algorithms, and examines its relationship to the concept of ageing as this is understood for human beings. Evolutionary Algorithms ...
Characterization of attenuation and respiratory motion artifacts and their influence on SPECT MP image evaluation using a dynamic phantom assembly with variable cardiac defects
(2017-04-01)
A phantom assembly that simulates the respiratory motion of the heart was used to investigate artifacts and their impact on defect detection. Methods: SPECT/CT images were acquired for phantoms with and without small and ...
Impact of respiratory motion correction on SPECT myocardial perfusion imaging using a mechanically moving phantom assembly with variable cardiac defects
(2017-08-01)
Background: The aim of this study was to determine the impact of respiratory motion correction on SPECT MPI and on defect detection using a phantom assembly. Methods: SPECT/CT data were acquired using an anthropomorphic ...
Nanotechnology to the rescue: using nano-enabled approaches in microbiological food safety and quality
(2017-04-01)
Food safety and quality assurance is entering a new era. Interventions along the food supply chain must become more efficient in safeguarding public health and the environment and must address numerous challenges and new ...
