Dwarf Galaxy Is An Under-powered Spiral Galaxy
NGC 1156 is an interesting dwarf galaxy for comparing cosmologies.
Electric Universe can offer explanations when none are offered now.
excerpt===
It is classified as a dwarf irregular galaxy, meaning that it lacks a clear spiral or rounded shape, as other galaxies have, and is on the smaller side, albeit with a relatively large central region that is more densely packed with stars.
Some pockets of gas within NGC 1156 rotate in the opposite direction to the rest of the galaxy, suggesting that there has been a close encounter with another galaxy in the past.

my comment:
NGC 1156 has interesting attributes unlike most galaxies in modern cosmology (MC).
Among them:
a) no black hole,
b) no dark matter,
c) inconsistent rotation of the irregular shape.
MC expects galaxies to rotate like our solar system where each object rotates about the barycenter, or the system's center of gravity.
Nearly every galaxy has an X-ray source at its core.
MC explains that source with a black hole with an extremely hot accretion disk. This black hole is always sized to be greater than the number of stars in the system to balance this assumed barycenter behavior.
MC requires black matter for every galaxy having rotation but the stars do not rotate about a barcenter so dark matter is the excuse for the wrong model for a spiral galaxy.
This particular galaxy has no X-ray source identified to justify (a).
The galaxy has an unusual rotation so there is no justification for (b).
Instead the anomalous rotation (c) is explained away by an unverifiable claim of an encounter with an unidentified galaxy with no details of this encounter, like the respective masses and velocities, trajectories, the distance, and time of this encounter.
The electric universe cosmology can offer believable explanations instead of this evasion.
Because there is an observed rotation there must be an axial electric current generating a galactic magnetic field exerting the Lorentz force for rotation.
There must be a birkelund current in dark mode along this galaxy's axis.
There must be a Z-pinch at the core of this dwarf galaxy.
The Z-pinch is a source of synchrotron radiation. Its highest frequency is determined by the intensity of the electric current.
The story offers no spectrum details for this core.
From the description the core is obscured by the dense stellar activity.
Perhaps the electric current to this galaxy is inadequate for X-rays.
Donald Scott has a pod cast explaining how a birkelund current filament with its multiple concentric current paths can result in counter rotating disks in a spiral galaxy.
NGC 1156 is another example of that behavior.
Because the galaxy rotation is present but not well defined, one explanation is a weaker magnetic field from the birkelund current filament weaker than typical for a definite spiral galaxy appearance.
The Hubble image shows noticeable stellar activity so the galaxy must have enough current to sustain what is observed.
The story's mention of a 'characteristic pink hue' is strange because the emission line of hydrogen is in ultraviolet.
Ultraviolet frequency will affect neutral hydrogen atoms, like in gas clouds near the core. Stars like our Sun radiate in ultraviolet. The story claims 'newborn stars' are doing this but actually most stars (i.e., similar to the Sun or more energetic) are probably capable.
This particular color must be from the the filters mentioned in the caption. That means some portion of this image has false colors. The caption makes this clear but not the story.
From the above observations NGC 1156, called a dwarf irregular galaxy, is just an under-powered spiral galaxy.
