G27.4+0.0
4C−04.71
- Right Ascension: 18 41 19
- Declination: −04 56
- Size (/arcmin): 4
- Type: S
- Flux density at 1 GHz (/Jy): 6
- Spectral Index: 0.68
Notes: Early references refer to G27.3−0.1 (Kes 73), a supposed larger remnant.
- Radio: Incomplete shell.
- X-ray: Diffuse emission, with central low period pulsar.
- Point sources: Central AXP.
- Distance: HI absorption suggests 7.5 to 9.8 kpc.
