A project to constrain emission from giant gaseous shells around high redshift radio galaxies

Mostrar todas las versiones(2)

Around half of the radio galaxies (radio-loud, type 2 quasars) at 2 are known to show strong Ly absorption features in their spectra, with a spatial extent at least as large as the background Ly nebulae closely associated with the AGN host galaxy ( 10-100 kpc). Based on their observed properties to...

description Around half of the radio galaxies (radio-loud, type 2 quasars) at 2 are known to show strong Ly absorption features in their spectra, with a spatial extent at least as large as the background Ly nebulae closely associated with the AGN host galaxy ( 10-100 kpc). Based on their observed properties to date, these absorbers are thought to be large-scale shells of gas surrounding the host galaxy and its Ly halo. Their origin is unclear, but is likely related to feedback processes in the host galaxy. In this work, we discuss our ongoing study of these absorbing shells using archival Hubble Space Telescope (HST) images of the rest-frame UV emission of 2.5 radio galaxies in order to search for these shells in emission, or to place constraints on their emission luminosity.
