Anheem, California Blackhill At a galaxy spraying center, you still can see that the gas around the past wanders around with radiation left in the clouds, as smoke erupts with pre -extinguished flames. Astronomers call these cosmic ghosts “light resonance”-and this is the high school junior Julian Shophero Found scanning the universe for the remnants of Supernova.
“These external gas regions of gas are an ionized by a super -aunt black hole, resulting in the result of its echo,” Shapiro said in a presentation on March 20, 2025 American Physical Society (APS) on March 20, 2025 American Physical Society (APS).
The 17 -year -old Shophero is a student at Dalton School in New York City. But in eliminating potential colleges and eliminating potential colleges, it is also an independent astronomer who presents at global conferences like this week’s APS meeting.
In fact, Shophero started working through her decaps2 Survey – an inventory of a southern galactic aircraft from the Dark Energy Camera Sero Tolloo Inter -American Observatory In Chile – Finding Sprinova’s remains and finding the debris of the stars exploded in the planets Nebulus.
But after zeroing one such thing, he found that his structure is not similar to the characteristic of a supernova rest, nor has he shown evidence of a supernova in his center. “It was a real surprise by stumbling from it,” Shapiro directly told Science.

The thing that believes it is a slight resonance, is probably standing in the field of Super Massey Black Hole. Using measurements from South Africa’s big telescopeIt was sprayed in the region of oxygen and ionized sulfur in the region – both indicators of surprised material. All of these symbols show that the object is now a post -immortal black hole, which once gave birth to radiation, which constituted the surrounding gas, which causes light to be emitted even after the black hole was silenced.
An epic echo
Shophero is currently echoing light in Qatar about 150 to 250,000 to 250,000 light years-which is about 1.5 to twice the width of the whole of the galaxy of the galaxy. And if his estimation is intact, he thinks that it may be a viable candidate for the echo of the greatest light ever.
“This item covers a large area of the sky, which is a bit easier to get pictures deep.”
According to Sasha PlavinA black hole researcher at Harvard University, who was not involved in this research, can help to learn more about how the black holes are treated in the hearts of galaxies.
“How carefully do I really like [Shapiro] Considering these photos, “Plvian told Science directly.” These galaxy events are always interested, and I think this echo is a great way to study them. “
Plvian is also interested in seeing how this new light measures in front of others – whether it is faster or slow From the current examples. “Keeping this discovery in a broader context can be useful in the future,” he said.
Since Shophero is continuing to study the echoes of light, he hopes to learn more about its formation with the measurement of various areas. But in the meantime, she is excited to contribute to black hole science – whether it is accidentally exposed to her.
“It is a surprise to me in this field of research,” he said. “But I hope this item, especially this item, helps enhance the knowledge of the galaxy activities that we do not understand much.”
