Continuum Reverberation in Bright Quasars Using NASA/ATLAS

Zachary Steyn, Christian Wolf, Christopher Onken +5

Variable continuum emission from AGN can be used to probe the structure of their accretion disks via reverberation mapping. Assuming a variable, hot inner light source irradiates t…

A catalogue of Type 2 active galactic nuclei in the 6dF Galaxy Survey

Sruthi Suresh, Wei Jeat Hon, Rachel L Webster +2

Active galactic nuclei (AGNs) are the compact, energetic central regions of galaxies, powered by supermassive black holes that accrete surrounding gas and dust. Their optical spect…

Deep Extragalactic VIsible Legacy Survey (DEVILS): Evolution of the Morphology-Density Relation

L. J. M. Davies, J. Doan, S. Bellstedt +6

Galaxies with different morphological characteristics likely have different evolutionary histories, such that understanding the mechanisms that drive morphological change can provi…

Detection of Ubiquitous Circumbinary Matter in Hot Subdwarfs Formed from Common-Envelope Ejections

Jiangdan Li, Christian Wolf, Jiao Li +7

The formation of compact binary systems is largely driven by their evolution through a common envelope (CE) phase, crucial for understanding phenomena such as type Ia supernovae an…

A new way to find symbiotic stars: accretion disc detection with continuum survey photometry

A. B. Lucy, J. L. Sokoloski, G. J. M. Luna +10

Symbiotic stars are binaries in which a cool and evolved star of luminosity class I-III accretes onto a smaller companion. However, direct accretion signatures like disc flickering…

The Variability Structure Function of the Highest-Luminosity Quasars on Short Timescales

Ji-Jia Tang, Christian Wolf, John Tonry

The stochastic photometric variability of quasars is known to follow a random-walk phenomenology on emission timescales of months to years. Some high-cadence restframe optical moni…

Discovering Changing-Look AGN in the 6dF Galaxy Survey using ATLAS Light curves

Neelesh Amrutha, Christian Wolf, Christopher A. Onken +4

Changing-Look Active Galactic Nuclei (CLAGN) are characterised by extreme variations in line emission over short timescales, mostly affecting broad H lines. While a few hundred…

Broad-line Active Galactic Nuclei in the 6dF Galaxy Survey

Wei Jeat Hon, Rachel Webster, Christian Wolf

The Six-degree Field Galaxy Survey (6dFGS) is a spectroscopic redshift survey of the Southern hemisphere completed in 2006. While it provides 136,304 spectra of mostly low-redshift…

Detection of circumstellar material in a normal Type Ia Supernova

F. Patat, P. Chandra, R. Chevalier +19

Type Ia supernovae are thought to be thermonuclear explosions of accreting white dwarfs that reach a critical mass limit. Despite their importance as cosmological distance indicato…
