Existence And Evidence Of Dark Matter In The Galaxy;

Scientists believe that dark matter provides the significant "scaffolding" for the universe, which acts as a glue that grabs the galaxies together. The astronomer's team recently found evidence for dark matter-free galaxies. Go through the details on this page to know more facts about dark matter, dwarf galaxy, and astronomer's research about the super matter around the galaxy.

No Trace Of Dark Matter

Astronomers, an international team led by researchers from the Netherlands, carried out forty-hour detailed measurements with sophisticated telescopes but found no trace of dark matter in the galaxy AGC 114905. In the Royal Astronomical Society Monthly Notices, researchers' findings will be presented.

Existence And Evidence Were Discovered And Strengthened

Astronomers have discovered six dark non-existent galaxies, and they were asked for taking another good step with the hope of seeing dark matter around the galaxy. The Very Large Range (VLA) telescope was used by PavelMancera Piña, University of Groningen, ASTRON, the Netherlands, and his colleagues for the observation. Thus, the dark matter-free galaxy evidence was strengthened after sharp measurements for an additional 40 hours.

Name And Category Of Galaxy

Galaxy is a question...The so-called super dwarf galaxy AGC 114905 is around 250 million light-years away. It is categorized as a rife dwarf galaxy. The name 'dwarf galaxy' does not refer to its size; it refers to luminosity.

Dwarf Galaxy Made Up Of Dark Matter

The size of the dwarf galaxy is about our own Milky Way galaxy's size; however, thousand times lesser stars. Of course, the prevailing view is that all galaxies are extremely wide-ranging dwarf galaxies only if they are made up of dark matter.

Data About Gas In Dwarf Galaxy

The team collected data about gas rotation in AGC 114905 using the VLA telescope between July and October 2020. A graph that shows the distance of the gas from the center of the galaxy as X-axis and gas's rotation speed as Y-axis was created. The graph shows that motions of the gas in AGC 114905 could be fully explained by means of just normal matter.

Problem Between Theory And Observation

PavelMancera Piña said that this is what they thought and expected. Because this discovery confirms their previous measurements. However, the present problem is the theory predicts that in AGC 114905, there should be dark matter. But his team's observation says there is no dark matt. The distinction between theory and observation is widening.

Views Of Scientists

According to scientists, AGC 114905 may have removed the dark object by nearby large galaxies. Scientists believe that the angle at which they view the galaxy may be another hypothesis that could change their results.

Examine For Another Ultra-diffuse Dwarf Galaxy

The team explores another ultra-diffuse dwarf galaxy in detail. If the team doesn't find a dark object trace there, then the case of non-dark matter-free galaxies will be strengthened.
