Ultra-luminous quasars at redshift from SkyMapper
Christian Wolf, Wei Jeat Hon, Fuyan Bian +6
The most luminous quasars at high redshift harbour the fastest-growing and most massive black holes in the early Universe. They are exceedingly rare and hard to find. Here, we pres…
Rest-frame UV and optical emission line diagnostics of ionised gas properties: a test case in a star-forming knot of a lensed galaxy at z~1.7
Ayan Acharyya, Lisa J. Kewley, Jane R. Rigby +7
We examine the diagnostic power of rest-frame ultraviolet (UV) nebular emission lines, and compare them to more commonly used rest-frame optical emission lines, using the test case…
Far-Infrared Properties of the Bright, Gravitationally Lensed Quasar J0439+1634 at z=6.5
Jinyi Yang, Bram Venemans, Feige Wang +11
We present IRAM/NOEMA, JCMT/SCUBA-2 and VLA observations of the most distant known gravitationally lensed quasar J0439+1634 at z = 6.5. We detect strong dust emission, [CII] 158 $μ…
