Jet-Launching Structure Resolved Near the Supermassive Black Hole in M87
Song A Day #1367 

PART A
F   A  Bb  C
Approximately 10% of active galactic nuclei 
F  C  Bb  C
exhibit relativistic jets, 
which are powered by accretion of matter onto 
super massive black holes, yeah.

PART B
Dm       C   Bb     Dm  C
While the measured widthprofiles of such jets on large scales agree with theories of magnetic collimation, 
predicted structure on accretion disk scales at the jet launch point has not been detected. 

PART A
We report radio interferometry 
observations at 1.3 mm wavelength 
of the elliptical galaxy M87 that spatially resolve the base of the jet in this source. 

PART B
The derived size of 5.5 ± 0.4 Schwarzschild radii is significantly smaller than 
the innermost edge of a retrograde accretion disk, suggesting that the M87 jet is powered by 

Bb    C   Bb  C
an accretion disk in a prograde orbit around a spinning black hole.

F   C
Black hole 
Bb    C
THAT's right I said black hole
Dm  C   Bb  C
Tantalizing data that burns deep in my soul suggesting, ooo
Black hole
A great big, big black hole
You can try and deny it but the science won't stay quiet*
