Combining large-area optical quasar surveys with the new far-infrared Herschel-ATLAS Data Release 1, we search for an observational signature associated with the minority of quasars possessing bright far-infrared (FIR) luminosities. We find that FIR-bright quasars show broad C iv emission line blueshifts in excess of that expected from the optical luminosity alone, indicating particularly power...

Today there is unanimous agreement that the country’s production model must change. But Greeks are very confused about the direction of the necessary changes. For, as the recent elections revealed, the vast majority of citizens have been brainwashed into believing outrageous promises about what the Greek leviathan state can do for them. Hence, the situation may be expected to worsen, unless Gre...

We consider the inverse scattering problem of reconstructing multiple impenetrable bodies embedded in an unbounded, homogeneous and isotropic elastic medium. The inverse problem is nonlinear and ill-posed. Our study is conducted in an extremely general and practical setting: the number of scatterers is unknown in advance; and each scatterer could be either a rigid body or a cavity which is not ...

[1] Terrestrial thermospheric dayglow emission from the coupled and overlapping c0 4 Su (0) and b0 Su (1) levels of molecular nitrogen, observed by the Far Ultraviolet Spectroscopic Explorer, is analyzed with the aid of a coupled channels quantum mechanical model of N2 spectroscopy and predissociation dynamics. Model emission spectra for the mixed c0 4 Su (0) b0 Su(1) X Sg(vi = 2, 6–9) transiti...

By considering the structure of holococcoliths (calcite plates that cover holococcolithophores, a haploid phase of the coccolithophore life cycle) as a photonic structure, we apply a discrete dipolar approximation to study the light backscattering properties of these algae. We show that some holococcolith structures have the ability to scatter the ultraviolet radiation. This property may repres...

We set out to determine the ratio, qIR, of rest-frame 8–1000-μm flux, SIR, to monochromatic radio flux, S1.4GHz, for galaxies selected at far-infrared (-IR) and radio wavelengths, to search for signs that the ratio evolves with redshift, luminosity or dust temperature, Td, and to identify any far-IR-bright outliers – useful laboratories for exploring why the far-IR/radio correlation (FIRRC) is ...

Reflections from artificial boundaries inhibit convergence of transient solutions to their steady limit. Far-field damping operators to suppress such reflections are presented for general first order hyperbolic systems, and particular reference is made to the compressible Euler equations. T h e damping operator has the following properties: (a) No reflections are generated due to the introducti...

Spectroscopic studies of molecular structure can strongly benefit from extending the conventional mid-IR range to the far-IR and THz regions, as low-frequency molecular vibrations provide unique fingerprints and high sensitivity to intra- and intermolecular interactions. In this work, the gas-phase conformer specific far-IR spectra of aminophenol isomers, recorded in the spectral range of 220-8...
