Signatures of winds and jets in the environment of supermassive black holes
Bidisha Bandyopadhyay, Christian Fendt, Dominik R. G. Schleicher +4
The Event Horizon Telescope Collaboration (EHTC) has presented first - dynamic-range limited - images of the black hole shadows in M87 and Sgr A*. The next generation Event Horizon…
General relativistic radiation transport: Implications for VLBI/EHT observations of AGN discs, winds and jets
Bidisha Bandyopadhyay, Christian Fendt, Dominik R. G. Schleicher +1
In 2019, the Event Horizon Telescope Collaboration (EHTC) has published the first image of a supermassive black hole (SMBH) obtained via the Very Large Baseline Interferometry (VLB…
Resolving accretion flows in nearby active galactic nuclei with the Event Horizon Telescope
Bidisha Bandyopadhyay, Fu-Guo Xie, Neil M. Nagar +5
The Event Horizon Telescope (EHT), now with its first ever image of the photon ring around the supermassive black hole of M87, provides a unique opportunity to probe the physics of…
Accretion models for LLAGNs: Model Parameter Estimation and Prediction of their Detectibility
Bidisha Bandyopadhyay, Dominik R. G. Schleicher, Neil Nagar +2
The Event Horizon Telescope (EHT) provides a unique opportunity to probe the physics of supermassive black holes through Very Large Baseline Interferometry (VLBI), such as the exis…
Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
Studying neutral hydrogen structures during the epoch of reionization using fractal dimensions
Bidisha Bandyopadhyay, T. Roy Choudhury, T. R. Seshadri
Fractal dimensions can be used to characterize the clustering and lacunarities in density distributions. We use generalized fractal dimensions to study the neutral hydrogen distrib…
Impact of Sommerfeld enhancement on helium reionization via WIMP dark matter
Bidisha Bandyopadhyay, Dominik R. G. Schleicher
Dark matter annihilation can have a strong impact on many astrophysical processes in the Universe. In the case of Sommerfeld-enhanced annihilation cross sections, the annihilation…
Helium reionization in the presence of self-annihilating clumpy dark matter
Bidisha Bandyopadhyay, Dominik R. G. Schleicher
The reionization of helium describes the transition from its singly ionized state to a doubly-ionized state in the intergalactic medium (IGM). This process is important for the the…
