Navigation of mini swimmers in channel networks with magnetic fields [PDF]

, 2013
Controlled navigation of swimming micro robots inside fluid filled channels is necessary for applications in living tissues and vessels. Hydrodynamic behavior inside channels and interaction with channel walls need to be understood well for successful ...

Observations of the Fluctuations in the Interplanetary Magnetic Field around L1 Point during the Solar Transient Events of 2024 with MAG Payload on board Aditya-L1 Spacecraft

The Astrophysical Journal
The magnetometer (MAG) payload on board India’s first solar mission, Aditya-L1, is a dual-sensor fluxgate magnetometer designed to measure the interplanetary magnetic field (IMF) while operating in a halo orbit around the first Sun–Earth Lagrangian point

Magnetic Field Amplification during a Turbulent Collapse

The Astrophysical Journal
The question of whether a dynamo can be triggered by gravitational collapse is of great interest, especially for the early Universe. Here, we employ supercomoving coordinates to study the magnetic field amplification from decaying turbulence during ...

Radio Polarisation Study of High Rotation Measure AGNs

Galaxies, 2017
As radio polarised emission from astrophysical objects traverse through foreground magnetised plasma, the physical conditions along the lines of sight are encrypted in the form of rotation measure (RM).

Magnetic fields around evolved stars [Elektronisk resurs] [PDF]

, 2018
There has long been evidence of magnetic fields in the extended envelopes of asymptotic giant branch (AGB) and red supergiant (RSG) stars. These stars are important contributors to the enrichment of the interstellar medium by dust and heavy elements ...

Resistive Scaling in the Magnetic Helicity-driven Inverse Cascade

The Astrophysical Journal
The inverse cascade in MHD turbulence plays a crucial role in various astrophysical processes such as galaxy cluster formation, solar and stellar dynamo mechanisms, and the evolution of primordial magnetic fields in the early Universe.
