A population of hypercompact HII regions identified from young HII regions
(2021-01-22)
Context. The derived physical parameters for young H II regions are normally determined assuming the emission region to be optically thin. However, this assumption is unlikely to hold for young H II regions such as ...
The angular clustering of infrared-selected obscured and unobscured quasars
(2014-08-21)
Recent studies of luminous infrared-selected active galactic nuclei (AGN) suggest that the reddest, most obscured objects display a higher angular clustering amplitude, and thus reside in higher mass darkmatter haloes. ...
