NASA's NICER maps debris from recurring cosmic crashes

80% Informative

Scientists have only recently encountered this class of X-ray flares, called QPEs, or quasi-periodic eruptions.

Ansky 's name comes from ZTF19acnskyy , the moniker of a visible-light outburst seen in 2019 .

Scientists' current understanding suggests the eruptions repeat until the disk disappears or the orbiting object disintegrates, which may take up to a few years .

NICER continued observing Ansky to explore how outbursts have evolved over time.

A paper about these results, led by Hernández-García and co-authored by Chakraborty , is under review.

Observational studies of QPEs will play a key role in preparing the science community for a new era of multimessenger astronomy, which combines measurements using light, elementary particles and space-time ripples called gravitational waves.
