DebrisWatch II: Digging deeper for geosynchronous debris
James A. Blake, Benjamin F. Cooke, Cristina Paragini +27
The geosynchronous (GSO) debris environment is continually evolving. Regular monitoring of the region is consequently of great importance, though the trade-off between coverage and…
An Extremely-High Velocity Outflow in SMSS J2157-3602, the most luminous quasar in the first 1.3 Gyr
Giustina Vietri, Paola Rodriguez Hidalgo, Amy Rankine +16
We report the discovery of an extremely high-velocity outflow (EHVO) in the most luminous ( 2.29 10 erg/s) QSO, SMSS J2157-3602, at z=4.692. Comb…
Supermassive black holes are growing slowly by
Samuel Lai, Christopher A. Onken, Christian Wolf +2
We investigate the black hole mass function at using XQz5, our recent sample of the most luminous quasars between the redshifts . We include 72 quasars with…
The accretion of a solar mass per day by a 17-billion solar mass black hole
Christian Wolf, Samuel Lai, Christopher A. Onken +5
Around a million quasars have been catalogued in the Universe by probing deeper and using new methods for discovery. However, the hardest ones to find seem to be the rarest and bri…
SkyMapper Southern Survey: Data Release 4
Christopher A. Onken, Christian Wolf, Michael S. Bessell +5
We present the fourth data release (DR4) of the SkyMapper Southern Survey (SMSS), the last major step in our hemispheric survey with six optical filters: u, v, g, r, i, z. SMSS DR4…
XQz5: A New Ultraluminous z5 Quasar Legacy Sample
Samuel Lai, Christopher Onken, Christian Wolf +2
Bright quasar samples at high redshift are useful for investigating active galactic nuclei evolution. In this study, we describe XQz5, a sample of 83 ultraluminous quasars in the r…
Discovery of A New Blue Large-Amplitude Pulsator in the SkyMapper DR2: SMSS J184506.82-300804.7
Seo-Won Chang, Christian Wolf, Christopher A. Onken +1
We report the discovery of a new Blue Large-Amplitude Pulsator, SMSS J184506-300804 (SMSS-BLAP-1) in Data Release 2 of the SkyMapper Southern Sky Survey. We conduct high-cadence ph…
Virial Black Hole Mass Estimates of Quasars in the XQ-100 Legacy Survey
Samuel Lai, Christopher A. Onken, Christian Wolf +4
The black hole (BH) mass and luminosity are key factors in determining how a quasar interacts with its environment. In this study, we utilise data from the European Southern Observ…
A Fast Radio Burst with frequency-dependent polarization detected during Breakthrough Listen observations
D. C. Price, G. Foster, M. Geyer +30
Here, we report on the detection and verification of Fast Radio Burst FRB 180301, which occurred on UTC 2018 March 1 during the Breakthrough Listen observations with the Parkes tel…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
The SkyMapper Transient Survey
Richard Scalzo, Fang Yuan, Michael J. Childress +7
The SkyMapper 1.3 m telescope at Siding Spring Observatory has now begun regular operations. Alongside the Southern Sky Survey, a comprehensive digital survey of the entire souther…
