A team of international astronomers identified an intermediate-mass black hole (IMBH) in the star cluster Omega Centauri using Hubble Space Telescope data.
Researchers arrived at this conclusion by analyzing the motion of seven stars in the cluster's central region with velocities much higher than other stars within it.

A team of international astronomers has made a significant discovery using data from NASA's Hubble Space Telescope. They identified the presence of an intermediate-mass black hole (IMBH) in the star cluster Omega Centauri, located near the Milky Way. The researchers arrived at this conclusion by analyzing the motion of seven stars in the cluster's central region that exhibit velocities much higher than other stars within it.
The estimated mass of this IMBH is at least 8,200 times that of our Sun, making it a rare find. The existence of such black holes is crucial for understanding various ways they form and grow in the universe. Previously, astronomers believed that IMBHs were elusive objects due to their scarcity.
The Hubble Space Telescope's long-term observations allowed researchers to detect these fast-moving stars, which provided compelling evidence for the presence of a massive object with a strong gravitational pull at the center of Omega Centauri. The discovery was published in the journal Nature and marks an important step forward in our understanding of black hole evolution.
A group of stars near the Omega Centauri cluster's core are moving so fast that they should have been ejected from it, implying the presence of a massive object.
The researchers argue that this massive object is a rare intermediate-mass black hole, weighing in at over 8,000 times the mass of the Sun.
These seven stars, despite their high velocities, are likely within the cluster due to an additional mass holding them in place. This could potentially be a single, compact object such as a black hole.
The estimated mass of this object is at least 8,200 times that of the Sun and possibly over 20,000 solar masses based on accelerating stars.
Intermediate-mass black holes, with masses between 100 and 100,000 times the mass of the Sun, are elusive astrophysical objects.
These fast-moving stars offer evidence of an intermediate-mass black hole in the center of χ Centauri.

The article contains a few informal fallacies and an appeal to authority. The author states that intermediate-mass black holes remain one of the most elusive members of an already exotic class of astrophysical objects, implying that they are difficult to find which is an appeal to authority based on expert knowledge. Additionally, the author references several studies and articles in support of their claims, but does not commit a formal fallacy themselves. There are also a few instances where the author uses sensational language such as 'mindboggling' to describe the discovery, which can be considered an inflammatory rhetoric.

An international team of astronomers used data from NASA’s Hubble Space Telescope to search for evidence of an intermediate-mass black hole (IMBH) in Omega Centauri.
The team identified seven stars that are moving too fast to be contained by the cluster, indicating the presence of a massive object with a gravitational pull keeping them close to the center.
This object is most likely an IMBH with a mass at least 8,200 times that of our sun.

The article contains several scientific statements and does not contain any obvious fallacies. However, there is an instance of an appeal to authority when the author quotes Maximilian Häberle stating that 'a very massive object is gravitationally pulling on these stars and keeping them close to the center. The only object that can be so massive is a black hole, with a mass at least 8,200 times that of our sun.' This statement implies that because Häberle is an expert in astronomy, his conclusion about the presence of an intermediate-mass black hole in Omega Centauri is valid. While this may be true, it does not negate the need for further evidence and investigation.

An intermediate-sized black hole, approximately 8,000 times more massive than the sun, has been identified at the center of the star cluster Omega Centauri.
The discovery was made by analyzing the motion of seven stars in the cluster's central region that are moving much faster than other stars.
This black hole is not as massive as a supermassive black hole and not as small as a garden-variety black hole, making it an important find for understanding various ways black holes form and grow.

No informal fallacies found. Some formal fallacies and dichotomous depictions present. The author presents an intermediate-sized black hole as a mysterious discovery without contextualizing it within existing scientific theories or previous research on black holes, which could lead to a misleading portrayal of the significance of this finding (Dichotomous Depiction). The author also attributes the discovery and interpretation of the data solely to Maximilian Häberle without acknowledging that this work likely involved collaboration with other researchers (Appeal to Authority). Additionally, there is an overgeneralization regarding the inability to find intermediate-sized black holes despite years of effort, which may oversimplify a complex scientific search process (Formal Fallacy: Hasty Generalization).
. . . finding them could shed light on the myriad ways that black holes can form and why some grow into gargantuan monsters.
The author attributes the discovery and interpretation of the data solely to Maximilian Häberle: “So people have wondered, is it difficult to find them because they are just not there, or because it’s difficult to detect them?” says Maximilian Häberle of the Max Planck Institute for Astronomy, Heidelberg, Germany.
The overgeneralization regarding the inability to find intermediate-sized black holes: “Despite plenty of effort over the years, however, scientists haven’t had luck in finding solid examples of black holes in the so-called intermediate size range . . .”.
