Phoenix A Black Hole vs. TON 618
Phoenix A Black Hole
The Phoenix A black hole, also known as Holmberg 15A*, is a supermassive black hole located at the center of the galaxy Holmberg 15A. This galaxy is situated within the Abell 85 galaxy cluster, approximately 700 million light-years away from Earth. The Phoenix A black hole has garnered interest due to its extraordinary size and the unique environment it inhabits.
The mass of the Phoenix A black hole is estimated to be around 100 billion solar masses, making it one of the the biggest black hole in the universe. Its size, or event horizon radius, is believed to be several times the diameter of our solar system. The Phoenix A black hole demonstrates the upper limits of black hole growth and challenges our understanding of the processes that lead to the formation of such massive objects.
The Phoenix A black hole and its host galaxy, Holmberg 15A, provide insights into the role of supermassive black holes in galaxy formation and evolution.

TON 618 Black Hole
TON 618 is an ultra-massive black hole located in the center of a distant quasar, approximately 10.4 billion light-years away from Earth. This black hole has attracted significant attention due to its extreme mass and the fact that it powers one of the brightest known quasars. The quasar itself, TON 618, is named after the Tonantzintla Observatory in Mexico, where it was first discovered.
The mass of the TON 618 black hole is estimated to be around 66 billion solar masses, making it one of the most massive black holes ever discovered. Its event horizon radius, or the boundary beyond which nothing can escape, is thought to be about 195 billion kilometers, which is roughly 1300 times the distance from the Earth to the Sun. The extreme mass of TON 618 has prompted scientists to investigate how black holes can grow to such colossal sizes, particularly considering the age of the universe.
The TON 618 black hole is associated with various phenomena and discoveries that have contributed to our understanding of supermassive black holes and their environments. The quasar TON 618 is an example of an active galactic nucleus (AGN), where the black hole is actively accreting matter from its surroundings, producing intense radiation in the process. Observations of TON 618 have provided insights into the physics of accretion and jet formation around supermassive black holes. Additionally, the extreme mass of TON 618 has implications for the growth of black holes in the early universe, suggesting that black holes may grow more rapidly than previously thought, or that there may be alternative pathways for their formation. The study of TON 618 also offers valuable information on the relationship between black hole mass and host galaxy properties, contributing to our understanding of the co-evolution of galaxies and their central black holes.
Comparative Analysis: Phoenix A Black Hole vs TON 618
Both Phoenix A and TON 618 are among the most massive black holes known to date, with Phoenix A being more massive at approximately 100 billion solar masses, compared to TON 618 estimated 66 billion solar masses. The event horizon radii of these black holes are also immense, with TON 618’s radius estimated to be around 195 billion kilometers. The Phoenix-A black hole has an estimated diameter of 5 million light-years, traversing its entire circumference at the speed of light would take a staggering 5 million years.. While both black holes exhibit extreme properties, the differences in their mass and size illustrate the range of supermassive black hole characteristics and challenge our understanding of black hole formation and growth.
In terms of accretion disks and jets, TON 618 is an active galactic nucleus, meaning it has a prominent accretion disk and produces intense radiation as it actively consumes surrounding matter. This radiation makes TON 618 one of the brightest known quasars. The accretion processes around TON 618 provide insights into the physics of jet formation and the behavior of matter near a supermassive black hole’s event horizon. On the other hand, Phoenix A’s accretion disk and jet activity are less well understood due to its relatively less active nature and the unique environment of its host galaxy, Holmberg 15A.
The surrounding environments of these black holes also differ. Phoenix A is located in the center of the massive elliptical galaxy Holmberg 15A, which resides in the Abell 85 galaxy cluster. This location points to a history of galaxy mergers and interactions that have influenced the growth of the Phoenix A black hole. In contrast, TON 618 is situated at the heart of a distant quasar, making its host galaxy and environment more challenging to study due to the intense radiation emitted by the active galactic nucleus.
The impact of these black holes on their host galaxies and neighboring regions can be significant. Phoenix A’s presence in the center of Holmberg 15A suggests a strong influence on the galaxy’s formation and evolution, as well as the potential to trigger star formation or disrupt the orbits of nearby stars through gravitational interactions. The history of galaxy mergers associated with Phoenix A also points to the role of supermassive black holes in driving galaxy evolution.
Similarly, TON 618’s extreme mass and the intense radiation emitted by its quasar can significantly impact its host galaxy and the surrounding environment. The energy output from the active galactic nucleus can drive outflows of gas and dust, affecting star formation rates and influencing the overall structure and evolution of the host galaxy. Additionally, TON 618’s immense gravitational pull can also disrupt the orbits of nearby stars and contribute to the growth and evolution of its host galaxy.
In both cases, the study of Phoenix A and TON 618 highlights the intricate relationship between supermassive black holes and the galaxies they inhabit, providing valuable insights into the processes that shape the universe on the grandest of scales.
Observational Techniques and Challenges

Studying supermassive black holes like Phoenix A and TON 618 presents several challenges. One of the primary challenges is their immense distance from Earth, which makes it difficult to obtain high-resolution images and detailed information about their properties and environments. In the case of TON 618, the quasar’s extreme brightness poses an additional challenge, as the intense radiation can outshine the host galaxy, making it difficult to study the galaxy’s properties and the black hole’s impact on its surroundings.
Another challenge in studying supermassive black holes is the need to observe across multiple wavelengths to gain a comprehensive understanding of their properties and behavior. This requires the use of various instruments and the coordination of observations, which can be logistically and financially demanding.
Technological advancements have played a crucial role in the study of black holes. The development of more powerful telescopes, such as the upcoming James Webb Space Telescope and the Extremely Large Telescope, promises to provide even more detailed observations of distant black holes like Phoenix A and TON 618.
