This X-ray source in the CDF-S has different properties from the as yetunexplained variable X-ray sourcesdiscovered in the elliptical galaxies NGC 5128 and NGC 4636 by Jimmy Irwin and collaborators. In particular, the CDF-S source is likely associated with the destruction of a neutron star or whit

Two Incredibly Bright X-Ray Flares Might Be Proof of Exotic Black Holes
Two x-ray flare sources detected recently by researchers at the University of Alabama compress those time scales even furtheracross six total flare events, Jimmy Irwin and colleagues observed eruptions bloom to their maximum intensity in less than a minute. In less than the time it would take you t

Mysterious X-Ray Blasts May Reveal New Stellar Objects
About an hour after a flare, the brightness returns back to normal. "We've never seen anything like this," Jimmy Irwin of the University of Alabama, who led the study, said in a statement. "Astronomers have seen many different objects that flare up, but these may be examples of an entirely new phen

Astronomers Discover Two Mysterious Cosmic Objects Belching Out Rapid X-Ray Flares
Weve never seen anything like this, Jimmy Irwin from the University of Alabama, lead author of a study describing the observations, said in a statement. Astronomers have seen many different objects that flare up, but these may be examples of an entirely new phenomenon.

University of Alabama researchers discover mystery flares in the Milky Way
Speaking to the Nature podcast team, Jimmy Irwin, an astronomer at the University of Alabama and first author of the paper, said: Theres actually very few types of objects in our universe that we know of that do this without blowing themselves up like a supernova or a gamma ray burst.
"A leading mystery in astrophysics is how the area around massive black holes can stay so dim, when there's so much fuel available to light up," said the study's co-author Jimmy Irwin, also of the University of Alabama. "This black hole is a poster child for this problem."
