Virgo’s characteristic radii (top) and splashback radii (bottom).
| Characteristic radius (Mpc) | |||
|---|---|---|---|
| R500c = 1.1 Mpc | R200c = 1.7 Mpc | Rvir = 2.1 Mpc | R200m = 2.9 Mpc |
| Splashback radius (Mpc) | |||
| 3D | DM (Rsp,DM) | Gas (Rsp,gas) | Pressure (Rsp,press) |
| Collapsing material | 3.4 ± 0.2 | 3.9 ± 0.2 | 4.3 ± 0.3 |
| Outflowing material | 4.3 ± 0.3 | 4.9 ± 0.3 | 5.5 ± 0.3 |
| Filament material | – | – | – |
| Full material | – | – | – |
| 2D | Surface density (Rsp,SD) | Emission measure (Rsp,EM) | Compton-y (Rsp,y) |
| 3.3 ± 0.2 | 3.9 ± 0.2 | 4.9 ± 0.3 | |
Notes. The splashback radii are identified using 3D radial profiles in the regions or using the full material and 2D-projected quantities. The value gives the centre of the bin of minimum gradient; the error bars are plus and minus one bin width at this radius.
