... The very close agreement between the model and number counts at 15 and 24 ЮМm strikingly implies that (1) the polycyclic aromatic hydrocarbon features remain prominent in the redshift band 0.5-2.5 and (2) the IR energy output has to be dominated by ~3У?1011 Lsolar to ~3У?1012 Lsolar galaxies from redshift 0.5 to 2.5. Combining Spitzer with Infrared Space Observatory deep cosmological surveys gives for the first time an unbiased view of the infrared universe from z=0 to 2.5. ... citations = 214 . ...

I would like to propose two new features for the axes annotation in the GMT. 1st: In astrophysics, we often work with great ranges of values (many orders of magnitude). ... However, GMT 3.2 allows to plot annotations for log10 axes every integer log10 value or even more frequently. The proposed patch allows to specify large steps for the log10 axes, in the form illustrated by an example below. 2nd: 10^0 instead of 1, and 10^1 instead of simply 10 do not look beautiful. ... The patch is here. ...

... The technique is based on the iterative subtraction of continuum estimates and eigenvector sky models derived from singular value decompositions of sky spectra and sky spectra residuals. ... The spectra may also be redshifted to a common radial velocity, though this feature isn't used for sky subtraction. svdvec is a Fortran program, called by IRAF as a foreign task, which decomposes an array of spectra, such as that created by svdprep , into eigenvectors using Singular Value Decomposition. ...

... We have observed and studied critical supercurrents, Ic, in cross-type Nb-Cu/Ni-Nb junctions with Josephson layers prepared from diluted ferromagnetic alloys. For suitable values of the exchange energy in the ferromagnet and the F-layer thickness we have observed Ic(T) oscillation with vanishing Ic for the definite values of T and dF. ... Critical supercurrents, Ic, in Nb-Cu(1-x)Ni(x)-Nb Josephson SFS junctions with F-layers prepared from ferromagnetic Cu(1-x)Ni(x) alloys have been studied. ...

Since the light from galaxies represents the integrated contribution of its consitutient stars, then we can learn about stellar populations in galaxies by modelling their light by summing up individual stellar spectra for different kinds of stars. ...
