Evidence for Supermassive Black Hole Binaries
Martin G. H. Krause, Martin A. Bourne, Silke Britzen +10
We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy…
Converged simulations of the nozzle shock in tidal disruption events
Fangyi Fitz Hu, Ilya Mandel, Rebecca Nealon +1
When debris from a star that experienced a tidal disruption events (TDE) after passing too close to a massive black hole returns to pericenter on the second passage, it is compress…
Leading & Trailing Spiral Arms in a Nearly Broken Protoplanetary Disc
Sahl Rowther, Rebecca Nealon, Richard Alexander +1
We perform three-dimensional smoothed particle hydrodynamics simulations to investigate the formation of spiral arms in misaligned circumbinary discs. In a nearly broken disc the m…
Tracing the formation and migration history: molecular signatures in the atmosphere of misaligned hot Jupiter WASP-94Ab using JWST NIRSpec/G395H
Eva-Maria Ahrer, Siddharth Gandhi, Lili Alderson +12
The discovery of hot Jupiters that orbit very close to their host stars has long challenged traditional models of planetary formation and migration. Characterising their atmospheri…
Disc-planet misalignment from an unstable triple system: IRAS04125
Rebecca Nealon, Jeremy L. Smallwood, Hossam Aly +5
The IRAS01425+2902 wide binary system was recently reported to have both a young planet and a puzzling geometric arrangement, where the planet and binary both orbit edge-on, but mi…
Modelling a Transiting Circumbinary Disc in the HD98800 System
Amena Faruqi, Grant Kennedy, Rebecca Nealon +1
We present synthetic optical light curves of the hierarchical HD98800 quadruple system over a decade-long period when the circumbinary disc encircling the system's B binary is expe…
