Small experiment using Lagragian passive tracers injected in the sequence of outputs of an ENZO MHD cosmological simulations, to track the formation history of filaments and threads in the intracluster medium .
tracer propagation code in #Julia language
-
Continuous rotation around the centre of the innermost 2Mpc^3 region of a cluster of galaxies simulated with ideal MHD with the ENZO code (Constrained Transport method here). Each cell is 4kpc large and the quantity on display is the temperature of the intracluster medium gas, almost towards the end of the simulation (z=0.2).
3D rendering done with SAO's DS9.

A woman merging with a beautiful full screen rendering of the simulated cosmic web in a simulation of mine...
This is was a segment from "Destinazione Terra" (Destination Earth) a video using scientific simulations by Daniela Paoletti and Diego Molinari, together the VisitLab at #CINECA, the biggest supercomputing centre in #Italy
It was presented at the Genova Science festival, and you can see the
full video here https://www.youtube.com/watch?v=5SAybgEBiXE -
#paperday on #astroph:
"Galaxy clusters in the LoTSS-DR3:
Catalogues and detection pipeline for diffuse radio emission" by Chiara Stuardi et al. including me
https://arxiv.org/pdf/2605.06400It presents the automated detection of diffuse radio emission in clusters observed in radio, using a Convolutional neural network (RADIO-UNET) trained on my #SimulatedUniverses !
Once in a while, a decent use of #AI to do something humans cannot do on this scale (as quickly).

A few rotating views around a massive (1e15 Msol) simulated cluster of galaxies using ENZO, the almost uniform resolution in the centre is 4kpc/cell and the total volume on display here is (2Mpc)^3.
Left: magnetic field strength (a lot of filaments!).
Right: baryonic density
All rotations are done using SAO's DS9 after post-processing in #Julia

Experiments in the generation (across several timesteps) and advection of Lagragian passive tracers to track the propagation of gas matter in new cosmological simulations of clusters of galaxies.
(tracers code in #Julia language, on top of ENZO-MHD simulations)
-
New murmuration movie of tracers following ordinary matter collapsing into a forming cluster of galaxies, in a fully Eulerian MHD Enzo simulation run at #CINECA (Italy).
Notice how this cluster assembles its mass mostly along filaments in the N-S direction.About 10 million tracers evolved in @julialang , covering about 10 billions of years of cosmic evolution

Wow, spent two good hours having remote interviews with two journalists who wanted to know more about "The simulation hypothesis" and (its negation using physics).
my contribution to that was indeed born like a "summer project" last yearhttps://mastodon.social/@franco_vazza/112602495770701830
and then it makes sense it is again discussed as a "summer divertissement"

Simulated growth of magnetic fields (left) and of baryonic matter (right) at the birth location of a massive cluster of galaxies, simulated with the Enzo code at #CINECA (Italy)

Unwrapping some of the new simulation data produced at #CINECA during holidays, where I multiply relaunched runs while mostly busy eating.
This is a composite view of the last simulated cluster, of galaxies (from z=30 to z=0) which we will use together with the others to study the possible formation mechanism of large scale radio emission.

#SimulatedUniverses
Progression of gas density and of the synchrotron radio emission from shock accelerated relativistic electrons if we had layer after layer of volumes along the line of sight, in a small portion of a cosmological simulation produced with the ENZO code on Leonardo #CINECA
Not entirely trivial to reconstruct the actual cosmic web distribution of gas based on the radio observation, given that the filling factors of the two fields are quite different. -
#6 of #SimulatedUniverses
This is an early ENZO ideal Magneto-Hydrodynamical simulation of the growth in gas temperature (left) and amplitude of magnetic fields (right) in a ~1e14 Msol galaxy cluster.
The time goes from z~10 to z~0 (about 13Gyr)Sadly, the simulation had to go.
What is wrong with it?
