A jet model for Galactic black-hole X-ray sources: Some constraining correlations
N. D. Kylafis, I. E. Papadakis, P. Reig +2
Some recent observational results impose significant constraints on all the models that have been proposed to explain the Galactic black-hole X-ray sources in the hard state. In pa…
Is the Galactic submillimeter dust emissivity underestimated?
K. M. Dasyra, E. M. Xilouris, A. Misiriotis +1
We present detailed modeling of the spectral energy distribution (SED) of the spiral galaxies NGC 891, NGC 4013, and NGC 5907 in the far-infrared and submm wavelengths. The model t…
Modelling the dust content of spiral galaxies: More dust mass vs. enhanced dust grain emissivity
K. M. Dasyra, E. M. Xilouris, A. Misiriotis +1
We present detailed modelling of the spectral energy distribution (SED) of the spiral galaxies NGC 891, NGC 4013, and NGC 5907 in the far-infrared (FIR) and sub-millimeter (submm)…
Radiation Transfer Models in Galaxies
N. D. Kylafis, E. M. Xilouris
The dust in galaxies makes radiation transport calculations in them absolutely necessary. It is not only common practice in Astrophysics, but also wisdom, to try to make as simple…
Spectra and time variability of galactic black-hole X-ray sources in the low/hard state
D. Giannios, N. D. Kylafis, D. Psaltis
we propose a jet model for the low/hard state of black-hole X-ray sources which explains a) the X-ray spectra, b) the timelag spectra, c) the increase in the amplitude (QPO and hig…
Modelling the spectral energy distribution of galaxies. III. Attenuation of stellar light in spiral galaxies
Richard. J. Tuffs, Cristina C. Popescu, Heinrich J. Voelk +2
We present new calculations of the attenuation of stellar light from spiral galaxies using geometries for stars and dust which can reproduce the entire spectral energy distribution…
