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…
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…
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…
