FIGARO simulation: FIlaments & GAlactic RadiO simulation

Abstract We produce the first low to mid-frequency radio simulation that incorporates both traditional extragalactic sources as well synchrotron cosmic web emission. The FIlaments & GAlactic RadiO (FIGARO) includes 10 unique 4° × fields, incorporating active galactic nucleii (AGNs), star-forming galaxies (SFGs), and emission out a redshift of z = 0.8 over frequency range 100–1 400 MHz. To do this, brings together recent 100 3 Mpc magnetohydrodynamic (Vazza et al. 2019, A&A, 627, A5), calibrated match observed relic population statistics, alongside updated ‘T-RECS’ code for simulating (Bonaldi MNRAS, 482, 2). Uniquely, AGNs SFGs are populated positioned in accordance with underlying matter density cosmological simulation. In this way, provides an accurate understanding apparent morphology, angular scales, brightness as—crucially—the clustering properties respect embedded population. find does not closely trace mass distribution web, but is instead dominated by shocked shells surrounding dark halos resembles large, undetected relics. also show that, kernels, clearly detectable cross-correlation techniques signal separable from offer public resource towards development detecting measuring web.
