Discovered Two Supermassive Black Holes in Our Galaxies

A new study has confirmed the existence of two supermassive black holes in galaxies close to us. Previously they were hidden by the clouds of gas and dust, obscuring the high power bursts when matter formed the universe being sucked into their inventory.
“These black holes in relatively close to the Milky Way, but they are still hiding from us until now. We like the monsters hiding under your bed “, sharing from researchers from the University of Durham Ady Annuar (UK), a member of the research team at the center of a black hole NGC 1448 galaxy.

Supermassive black holes really invisible to us, because they do not emit light. But when the matter falls through the event horizon boundaries, they heat up and generate radiation that can be observed on the electromagnetic spectrum. This process occurs in the center of the galaxy contains a supermassive black hole, creating a brilliant performance can be detected from a distance of billions of light years, but only with favorable conditions.

The problem is that most active nuclei are said to be surrounded by clouds of gas and dust blocks most of the light emitted. If you have a vantage point to observe, you will see a performance incredible light, but when viewed from the side, you can not see anything.

“Just like we can not see the sun on a cloudy day, we can not directly see the bright cores of galaxies really how by gas and dust surrounding the central area operations” Peter Boorman from the University of Southampton (UK), who led a study of black hole in the galaxy IC 3639, said. “When the level of cover up, only the X-rays have the largest new energy can escape to be observed by us,” he added.

The new findings may be made by NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array – spectral telescopes) – an X-ray telescope placed in space. Using NuSTAR, Boorman’s group measured the X-ray emission from high energy to IC3639, from Earth galaxy 170 million light years away, a relatively close distance, the universe itself is said to increase the lead 45 billion light years.

IC 3639 has been previously observed by the Chandra X-ray observatory NASA and Japan’s Suzaku satellite, but the new data from NuSTAR is the first confirmed that this galaxy has a private real galaxies activity.

“The black hole (of IC 3639) is very faint, it requires extremely sensitive observed in the high-energy X-rays to classify it is obscured. IC 3639 turned out to be a powerful glow is due to the glow from hot iron atoms, which until now has not been fully understood, “Boorman said.

In another study, the team used NuSTAR Annuar also to observe a giant black hole that is even closer to Earth, at a distance of 38 million light-years, or about 360 trillion kilometers, so no need to worry there are some surprises about the universe surrounding us in the near future.

“These recent discoveries suggest definitely the question that how many other supermassive black holes that we still ignore, even in the universe of our neighborhood,” Annuar said.
