Astronomers just discovered 18 new black holes gorging themselves on nearby stars

A recently published study in The Astrophysical Journal details 18 new black holes discovered eating away at nearby stars. Astronomers discovered the black holes when they noticed new tidal disturbance events (TDEs), extreme cases where a star was tidally pulled into a blackhole ..

The stars are ripped into shreds and slowly eaten by the black hole, creating an enormous burst of energy that can be seen all across the electromagnetic spectrum. Scientists look for these TDEs when trying to locate black holes in space. So far, this has been a great help.

These 18 new black holes were previously “hidden” as they required an unconventional band to spot: infrared. The discovery of these hidden TDEs more than double the current catalog of known TDEs in the universe, though, making this discovery even more important.

The reason that we need to rely on infrared to spot these TDEs is that they are located in particularly dusty galaxies. The black holes can be covered in tons of debris that has been created by planetary formations or the death of stars. As such, the black holes at their centers become hard to see.

By peering through the universe with an infrared band, though, the researchers at MIT were able to pick out many more TDEs, thus giving the impression of 18 new black holes that we hadn’t uncovered just yet. They’re also scattered throughout the universe and found in different types of galaxies.

Many of these sources don’t show up in optical bands, either, the lead author on the new findings explained. (via Phys.org)As such, using infrared was mandatory for spotting them and being able to add them to the catalog. One of those detected is also the closest TDE detected thus far, and it has opened up new ways for researchers to search for actively feeding black holes.
