This interactive shows the cosmic web inferred from Lyman Alpha tomography at z~2.0-2.5 using a dynamical forward model reconstruction technique (TARDIS, Horowitz et al. 2020, 2021). The cosmic web classification was derived from the modelled dark matter distribution using the eigenvalues of the deformation tensor, known as the "T-web" method.

Control

• LMB: Rotate the camera around the current point-of-interest
• MMB/wheel: Change the distance to the current point-of-interest
• RMB: Move the camera parallel to the viewing plane

In the config panel, you can change a couple of display parameters to highlight certain features. The transfer function consists of 4 thin uniformly distributed Gaussians whose opacity (alpha) can be adjusted individually. Additionally, the volume can be clipped along the x-, y- and z-direction.
