Pitt researcher helps discover smallest known black hole
Alexander Hanna Staff Writer
Out in the vast blackness of space lie two stars dancing in space. These stars are partners, known as binary stars, that exist together in stellar multiplicity. They orbit around a single large mass that cannot be seen by the naked eye or even a telescope. However, thanks to a group of astronomers, including one at the University of Pittsburgh, we now know that our third dance partner is one of the smallest black holes ever found. Carlos Badenes, an associate profes-
sor of physics and astronomy, recently co-authored a paper detailing the discovery of a black hole in the Auriga constellation that is significantly smaller than the average black hole. According to a press release, lead author Todd A. Thompson of Ohio State University and affiliated authors, including Badenes, published “A noninteracting low-mass black hole–giant star binary system” in the journal Science on Nov. 1. With the advent of this discovery, scientists can now establish an unbiased size distribution of black holes, a task that has been evading scientists for decades.
Badenes stated that astronomers studied black holes by analyzing the black hole’s accretion, which is the black hole’s ability to eat material from matter around it. This accretion emits light that observers can see and study via X-ray wavelengths. However, Badenes highlights a problem with this method. “The problem is that the more massive the black hole is, the more luminous the material is going to become,” Badenes said. “When you try to take a census of the black hole population using this method, you end up with black holes that See Black Hole on page 2
Police are seeking a suspect responsible for an attempted burglary of Bruegger’s Bagels on Forbes Avenue Monday afternoon, according to a crime alert issued to Pitt students the same evening. University and City police responded to the incident shortly after 4:30 p.m., according to the alert. The victims reported that the man demanded they open the cash register and hand over the money inside. After the victims were unable to open the register, the victims said the suspect left the shop and fled north on Atwood Street. Though they didn’t see the man holding a weapon, he had a hand inside his pocket, which they assumed contained a firearm, the alert said. The alert described the suspect as a black man in his 40s with a short, slender build and stubble. At the time of the robbery, he was wearing a hat, a black leather jacket and carpenter-style khaki pants and had a red bag and a blue drawstring backpack. The alert requested that anyone with information call City police at 412-4226520, referencing CCR #19-230613 in the call, or call Pitt police at 412-6242121 and reference report #19-03684.
