A Systematic Survey for z < 0.04 Changing-Look AGNs

Madhooshi R. Senarath, Michael J. I. Brown, Michelle E. Cluver +6

We have conducted a systematic survey for z 0.04 active Galactic nuclei (AGNs) that may have changed spectral class over the past decade. We use SkyMapper, Pan-STARRS and the V…

SkyMapper colours of Seyfert galaxies and Changing-Look AGN

Christian Wolf, Jacob Golding, Wei Jeat Hon +1

We study the utility of broad-band colours in the SkyMapper Southern Survey for selecting Seyfert galaxies at low luminosity. We find that the index, built from the ultraviol…

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…

Discovery of the most ultra-luminous QSO using Gaia, SkyMapper and WISE

Christian Wolf, Fuyan Bian, Christopher A. Onken +5

We report the discovery of the ultra-luminous QSO SMSS~J215728.21-360215.1 with magnitude and W4 at redshift 4.75. Given absolute magnitudes of $M_{145,\rm AB}=-29.…

Discovery of two bright quasars with SkyMapper, Pan-STARRS1 and WISE

Zefeng Li, Christian Wolf, Fuyan Bian +5

We present a search for bright quasars using imaging data from SkyMapper Southern Survey, Pan-STARRS1 and the Wide-field Infrared Survey Explorer (WISE). We select two set…
