The Astrophysical JournalThe discovery of quasars and their supermassive black holes (SMBHs) over 10 ^9 ${M}_{{\rm{\odot }}}$ merely hundreds of millions of years after the Big Bang generates tension with the idea of Eddington-limited accretion and pressures the community into ...

The Astrophysical Journal LettersStars falling too close to massive black holes in the centers of galaxies can be torn apart by the strong tidal forces. Simulating the subsequent feeding of the black hole with disrupted material has proved challenging because of the range of timescales ...

Late-time Radio Flares in Tidal Disruption Events
The Astrophysical JournalRadio monitoring unveiled late (hundreds to a thousand days) radio flares in a significant fraction of tidal disruption events. We propose that these late-time radio flares are a natural outcome if the surrounding density profile flattens outside the ...

Variability: A X-ray ruler for the AGN structure model
EPJ Web of Conferences, 2012 Validating our understanding of the innermost structure of Active Galactic Nuclei (AGN) would require resolving sub-parsec scales. Lacking adequate direct imaging, X-ray astronomy can still contribute to this undertaking through the study of spectral ...

Stable Collisionless Tori around Kerr Black Holes
The Astrophysical JournalIn low-luminosity active galactic nuclei like M87 ^* and Sgr A ^* , the accretion flow in the vicinity of the black hole is in the collisionless regime, meaning that the collisional mean free path of charged particles is much larger than the dynamical ...

Autoencoder-enhanced joint dimensionality reduction for constrained Bayesian optimisation
Machine Learning: Science and TechnologyBayesian Optimisation (BO) is a sample-efficient method for optimising expensive black-box functions, making it particularly suitable for engineering problems where gradients are unavailable and evaluating the objective or constraints is computationally ...
