Figure Reference Title Description Number of Figure Data Items Identifier Download Figure Details
Figure 1 Paper 2 Force direction and normalised (logarithmic) intensity on a linear dipole positioned at $(x,y)$ and generated by a second dipole located at the origin. Both dipoles are pointing in the positive $y$ direction. The arrows have the same lengths as they only represent the direction of the force. The colour plot shows the magnitude of $log[pi epsilon_0 |mathbf{f}|/(|mathbf{p}_1||mathbf{p}_2|)]$ and the $x$ and $y$ axes are in meters. 0 CF/17/190 Download
Figure 2 Paper 2 Time evolution of interacting filaments for two representative cases. In the upper panels, the initial separation is horizontal, $w_a=w_b=5$ and $epsilon=2$. In the lower panels, the initial separation is vertical, $w_a=5$, $w_b=7.5$ and $epsilon=1.5$. The colour plots show how the density perturbation evolves at intervals separated by $475$ normalised time units. Note that the colour bar is normalised to the maximum density in each frame in order to enhance the filaments' structures. White lines represent contours of $phi$ at $0.1$ and $-0.1$ (solid and dashed, respectively). 0 CF/17/191 Download
Figure 3 Paper 2 Time evolution of the radial velocity of the centre of mass of the two filaments. Blue, green, red and cyan curves represent $epsilon$ equal to $1.5$, $2$, $3$ and $5$. Solid and dashed lines correspond to an initial horizontal and vertical separations, respectively. Black circles show the reference velocity of a single, not interacting filament. 0 CF/17/192 Download
Figure 4 Paper 2 Variation of the maximum velocity, $Delta V_%$ with respect to reference case as a function of the separation of the filaments. Each frame represents a different combination of filament sizes. Crosses and plus (squares and diamonds) markers correspond to 2D (3D) simulations with initial vertical and horizontal separation respectively. Cases with strong interactions with the boundaries are not shown (see e.g. $w_A=w_B=7.5$). 0 CF/17/193 Download
Figure 5 Paper 2 Same filaments as in Fig.ref{fig2} in 3D for $t=875$ (colour bar normalised to the maximum density). The shaded region in the back represents the target. 0 CF/17/194 Download
