3. The AstroStat Slog afterglow
... Posts tagged ?afterglow? ... Without an optical afterglow, a galaxy within the 2 arc second error region of a GRB x-ray afterglow is identified as a host galaxy; however confusion can rise due to the facts that 1. the edge of a galaxy is diffused, 2. multiple sources could exist within 2 arc second error region, 3.the distance between the galaxy and the x-ray afterglow is measured by projection, and 4. lensing causes increase of brightness and position shifts. ...

9. Complete ionisation of the neutral gas: why there are so few detections of
From the first published z > 3 survey of 21-cm absorption within the hosts of radio galaxies and quasars, we found an apparent dearth of cool neutral gas at high redshift. ... This indicates that he non-detection of 21-cm absorption is not due to the sensitivity limits of current radio telescopes, but rather that the lines-of-sight to the quasars, and probably the bulk of the host galaxies, are devoid of neutral gas. | ...

The observers think that they are smart, but it is only thanks to these new telescopes that all the exciting recent progress has been made in the study of the high redshift universe. ... By redshift ten, some knots (where filaments and sheets join) are getting dense enough to form galaxies, and the first light in the universe switches on. ... By redshift 5, clusters of galaxies are centred on these knots. ...

17. Informational system "Evolution of RG"
The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... 1993: . ... It was shown that the degree of the drop in turbulence depends on the magnetic field strength and the fact that it is completely suppressed at the field strengths of 4-5 kG. As a consequence, there arise the conditions of unimpeded diffusion of chemical elements under the influence of radiation pressure, so the degree of chemical anomalies depends on the magnetic field strength. ...
