Webb11 dec. 2015 · AGNs and star-forming galaxies occupy distinct regions in the BPT diagram due to differences in the spectral energy distribution (SED) of their ionizing radiation, as … WebbIn the low-redshift Universe, the most powerful radio sources are often associated with gasrich galaxy mergers or interactions. We here present evidence for an advanced, gas-rich ('wet') merger associated with a powerful radio galaxy at a redshift of z similar to 2. This radio galaxy, MRC 0152-209, is the most infrared-luminous high-redshift radio galaxy …

Webbassumption of the star-forming galaxies’ spectral energy distri-bution (SED) might cause such a trend. The exact shape of the radio SED of star-forming galax-ies is usually assumed to be a superposition of the steep syn-chrotron spectrum, described by a power law, and a ˘10% contribution at 1:4GHz of a flat free–free spectrum (Condon 1992). cactus based leather

WebbTemplate UV-optical spectra of quiescent and starburst galaxies are presented and used to derive K-corrections as a function of morphological type and redshift. IUE observations and archival data are used for the UV template spectra. The optical spectra are from ground-based observations obtained in apertures that match closely the 200 arcsec^2^ IUE … Webbgalaxies Review Revisiting the Equipartition Assumption in Star-Forming Galaxies Amit Seta 1,2,* and Rainer Beck 3 1 School of Mathematics, Statistics and Physics, Newcastle University, Newcastle Upon Tyne NE1 7RU, UK 2 Research School of Astronomy and Astrophysics, Australian National University, Canberra, ACT 2611, Australia 3 Max-Planck … WebbHowever, Tacconi & Young (1985) suggest that irregular galaxies form stars more efficiently than do spirals and, as a consequence, that the present star formation rate of NGC 3738cannot be sustained for more than 10 8 yr. The UV spectrum resembles those of H II regions (cf. Rosa et al. 1984) with emission dominated by massive, hot stars. clyde savannah school tax bill
