The Origins of Gas Accreted by Supermassive Black Holes: The Importance of Recycled Gas
The Astrophysical JournalWe investigate the fueling mechanisms of supermassive black holes (SMBHs) by analyzing 10 zoom-in cosmological simulations of massive galaxies, with stellar masses 10 ^11–12 M _⊙ and SMBH masses 10 ^8.9–9.7 M _⊙ at z = 0, featuring various major and ...

Evolution in the black hole mass-bulge mass relation: a theoretical perspective
, 2005 We explore the growth of super-massive black holes and host galaxy bulges in the galaxy population using the Millennium Run LCDM simulation coupled with a model of galaxy formation.

STELLAR VELOCITY DISPERSION IN DISSIPATIVE GALAXY MERGERS WITH STAR FORMATION [PDF]
, 2013 In order to better understand stellar dynamics in merging systems, such as NGC 6240, we examine the evolution of central stellar velocity dispersion (σ*) in dissipative galaxy mergers using a suite of binary disk merger simulations that include feedback ...

The Astrophysical JournalThe active galactic nucleus (AGN) channel for the formation of binary black hole (BBH) mergers has been previously studied as a potential formation channel for the merging compact binaries observed by the LIGO–Virgo–KAGRA (LVK) scientific collaboration ...

Consequences of Mechanical and Radiative Feedback from Black Holes in Disc Galaxy Mergers [PDF]
, 2013 We study the effect of AGN mechanical and radiation feedback on the formation of bulge dominated galaxies via mergers of disc galaxies. The merging galaxies have mass-ratios of 1:1 to 6:1 and include pre-existing hot gaseous halos to properly account for

Somato‐Cognitive Action Network in Focal Dystonia
Movement Disorders, EarlyView.Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

RIOJA. Complex Dusty Starbursts in a Major Merger B14-65666 at z = 7.15
The Astrophysical JournalWe present JWST NIRCam imaging of B14-65666 (“Big Three Dragons”), a bright Lyman-break galaxy system ( M _UV = −22.5 mag) at z = 7.15. The high angular resolution of NIRCam reveals the complex morphology of two galaxy components: galaxy E has a compact

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Journal of Polymer Science, EarlyView.Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

, 2012 We present a new approach to study galaxy evolution in a cosmological context. We combine cosmological merger trees and semi-analytic models of galaxy formation to provide the initial conditions for multi-merger hydrodynamic simulations.
