Iterative Poisson Solvers for Self-gravity with the GPU Code Astaroth
Ruben Krasnopolsky, Touko Puro, Wei-Wen Li +5
We present the development and benchmarking of Poisson solvers for graphics processing units (GPUs). Implemented in the Astaroth platform, the solvers feature high computational ef…
Magnetic Spirals in Accretion Flows Originated from Misaligned Magnetic Field
Weixiao Wang, Miikka S. Väisälä, Hsien Shang +4
Misalignment between rotation and magnetic field has been suggested to be one type of physical mechanisms which can easen the effects of magnetic braking during collapse of cloud c…
Characterization of dense Planck clumps observed with Herschel and SCUBA-2
E. Mannfors, M. Juvela, L. Bronfman +15
We aim to characterize a diverse selection of dense, potentially star-forming cores, clumps, and clouds within the Milky Way in terms of their dust emission and SF activity. We stu…
The supernova-regulated ISM. III. Generation of vorticity, helicity and mean flows
Maarit J. Käpylä, Frederick A. Gent, Miikka S. Väisälä +1
The forcing of interstellar turbulence, driven mainly by supernova explosions, is irrotational in nature, but the development of significant amounts of vorticity and helicity, acco…
The supernova-regulated ISM. IV. A comparison of simulated polarization with Planck observations
Miikka S. Väisälä, Frederick A. Gent, Mika Juvela +1
The efforts for comparing dust polarization measurements with synthetic observations from MHD models have previously concentrated on the scale of molecular clouds. Here we extend t…
Mapping the prestellar core Ophiuchus D (L1696A) in ammonia
Jukka Ruoskanen, Jorma Harju, Mika Juvela +5
The gas kinetic temperature in the centres of starless, high-density cores is predicted to fall as low as 5-6 K. The aim of this study was to determine the kinetic temperature dist…
Influence of Ohmic diffusion on the excitation and dynamics of MRI
Maarit J. Korpi, Petri J. Käpylä, Miikka S. Väisälä
In this paper we make an effort to understand the interaction of turbulence generated by the magnetorotational instability (MRI) with turbulence from other sources, such as superno…
