Supernova Bullet

Supernova N49 (in LMC) in X-ray has apparently ejected a very fast object.

from the Chandra story in 2018:
'
X-ray data from Chandra reveals the presence of a bullet-shaped object to the lower right.

This "bullet," which is traveling at 5 million miles per hour, is evidence that the supernova explosion was highly asymmetric
reveals evidence for a bullet-shaped object being blown out of a debris field left over from an exploded star.
'

From Harvard-Smithsonian:
'
N49 is the brightest supernova remnant in the LMC. A massive star produced a strong wind that cleared a low density bubble around it. When the star exhausted its supply of hydrogen, it exploded, sending a shock wave throught he interstellar gas. The shock wave has now encountered the shell of dense gas at the edge of the bubble, especially in the lower left part of the image. In the dense gas, the shock slows to 100 - 300 km/s and produces bright emission from neutral hydrogen, doubly ionized oxygen and four-times ionized neon. The neon emission is difficult to detect because it lies in the near Ultraviolet part of the spectrum It is important for filling the gap between emission at visible wavelengths produced by 100 km/s shock waves and X-ray emission produced by shocks faster than 500 km/s.

From a space-dot-com story:
'
The material ejected from the Crab Nebula is moving at more than 3 million mph (4.8 million kph).
'

Everything emitting radiation in N49 must involve shock waves or a strong wind.

This motion of material must be driven by electromagnetic forces. Gravity only attracts and cannot eject anything at a substantial speed.

I cannot find online any spectra for anything here in N49.

The assumption is a star exploded and the ejected material caused X-rays from the resulting collisions.

I had posted on August 1 the Crab Nebula 'remnants' are electrically active.  The core of  M1 (or NGC 1952, or Taurus A) exhibits a source of synchrotron radiation. I would not expect that activity from any remnant of an explosion nor from a neutron star, the assumed remnant at the core. The post had a link to the spectrum.

 The N49 description implies it is like M1. The images, in any wavelength, of both objects are rather similar.

From the attached NASA story about M1 - which should apply to N49:

 
'
This view of the supernova remnant obtained by the Spitzer Space Telescope shows an infrared view of this complex object. The blue-white region traces the cloud of energetic electrons trapped within the star's magnetic field, emitting so-called "synchrotron" radiation. The red features follow the well-known filamentary structures that permeate this nebula. Though they are known to contain hot gasses, their exact nature is still a mystery that astronomers are examining.

The energetic cloud of electrons is driven by a rapidly rotating neutron star, or pulsar, at its core. The nebula is about 6,500 light-years away from the Earth, and is 5 light-years across.
'

The text clearly reveals a big problem for cosmologists. especially with  'still a mystery' and 'trapped electrons' emit 'so-called synchrotron radiation' so there is much confusion here.

These fascinating electrical behaviors are 'still a mystery' to some, but not EUT. This bullet sounds like a jet emitted by a plasmoid, like in M87.
