Supertransient Magnetohydrodynamic Turbulence in Keplerian Shear Flows: The role of the Hall Effect
Danilo Morales Teixeira, Erico Luiz Rempel
Space and astrophysical plasmas are frequently found in the regime of differential rotation, where the presence of a magnetic field can result in the magnetorotational instability,…
No Evidence for Bardeen-Petterson Alignment in GRMHD Simulations and Semi-Analytic Models of Moderately Thin, Prograde, Tilted Accretion Disks
Viacheslav V. Zhuravlev, Pavel B. Ivanov, P. Chris Fragile +1
In this paper we introduce the first results that use data extracted directly from numerical simulations as inputs to the analytic twisted disk model of Zhuravlev & Ivanov. In both…
Conservative GRMHD Simulations of Moderately Thin, Tilted Accretion Disks
Danilo Morales Teixeira, P. Chris Fragile, Viacheslav V. Zhuravlev +1
This paper presents our latest numerical simulations of accretion disks that are misaligned with respect to the rotation axis of a Kerr black hole. In this work we use a new, fully…
Modeling very long baseline interferometric images with the cross-entropy global optimization technique
Anderson Caproni, Hektor Monteiro, Zulema Abraham +2
We present a new technique for obtaining model fittings to VLBI images of astrophysical jets. The method minimizes a performance function proportional to the sum of the squared dif…
Precessing AGN Jets, Bubbles and Cooling Flows
D. Falceta-Goncalves, A. Caproni, Z. Abraham +2
Several galaxy clusters are known to present multiple and misaligned pairs of cavities seen in X-rays, as well as twisted kiloparsec-scale jets at radio wavelengths. It suggests th…
Precessing jets and X-ray bubbles from NGC1275 (3C84) in the Perseus galaxy cluster: a view from 3D numerical simulations
D. Falceta-Goncalves, A. Caproni, Z. Abraham +2
The Perseus galaxy cluster is known to present multiple and misaligned pairs of cavities seen in X-rays, as well as twisted kiloparsec-scale jets at radio wavelengths; both morphol…
