The Unfolding Mystery of ‘Jetty McJetface’: What a Brightening Black Hole Tells Us About the Universe
For four years, astronomers have been watching a supermassive black hole relentlessly brighten, a phenomenon that challenges conventional understanding of these cosmic giants. Officially named AT2018hyz, but affectionately dubbed “Jetty McJetface” – a playful nod to the internet’s penchant for naming things – this black hole continues to “burp out” the remnants of a star it shredded years ago. The ongoing observations, led by University of Oregon astrophysicist Yvette Cendes, suggest the radio blast from Jetty McJetface could peak in 2027, offering a unique opportunity to study the aftermath of a stellar disruption.
Why is This Black Hole Different?
Typically, when a star wanders too close to a supermassive black hole, it’s torn apart in a dramatic event called a tidal disruption event (TDE). Astronomers usually observe a bright flash of light, which then fades over time. However, Jetty McJetface defied expectations. While the initial optical detection in 2018 seemed routine, subsequent radio observations revealed a signal that not only persisted but continued to grow stronger years later. This “late blooming” behavior is what sets it apart.
Decoding the Signals: Spherical Outflow or Hidden Jet?
The team’s analysis, published in The Astrophysical Journal, points to two possible explanations for the sustained brightening. One theory suggests a roughly spherical outflow of material, launched around 620 days after the initial disruption, moving at about one-third the speed of light. The other proposes an early jet launch, initially obscured from view, that has turn into visible as it slows and spreads. Determining which scenario is correct is a key focus of ongoing research.
Current data indicates the black hole’s radio output is now 50 times brighter than when first detected in 2019, with energy levels rivaling those of a gamma-ray burst – an incredibly powerful cosmic event. In fact, the energy output is estimated to be a trillion to 100 trillion times greater than that of the fictional Death Star from Star Wars.
The Power of Radio Astronomy
Cendes’ work highlights the importance of radio astronomy in unraveling the mysteries of black holes. While optical, ultraviolet, and X-ray observations provide valuable insights, radio signals can reveal details about winds and jets that interact with surrounding gas. The research utilizes data from radio arrays in New Mexico and South Africa, along with observations from the Atacama Large Millimeter/submillimeter Array (ALMA).
Implications for Future Black Hole Research
The unusual behavior of Jetty McJetface is prompting astronomers to rethink how they monitor TDEs. Many events are observed briefly and then left, but this case demonstrates that significant activity can occur years after the initial disruption. This suggests a need for longer-term monitoring, particularly with radio and millimeter telescopes.
understanding the mechanisms behind these delayed outbursts can provide valuable clues about how black holes launch jets and outflows, and how matter behaves in extreme gravitational environments. Improved models could also help identify more off-axis jets – those not directly pointed towards Earth – that might otherwise go unnoticed.
What to Expect in 2027
Researchers predict the radio signal from Jetty McJetface will continue to increase exponentially before peaking in 2027. A turnover in the signal at certain frequencies around that time could provide crucial evidence to support one of the proposed models. Coordinated observations from telescopes around the globe will be essential to capture this turning point.
