In galaxies that are disappointed, pipsqueak is a & # 39; clear

There are clear blue X-ray high-energy light embosses captured by the NASA NASA resolution covered by the flexible image of Whirlpool galaxy (in the middle of the image) and the companion disease, M51b (bright white spot- gray above the Whirlpool), built by Survey Sloan Digital Sky.Credit: NASA / JPL-Caltech, IPAC

In the nearby Whirlpool disease and the companion disease, M51b, there will be two higher black holes; Heat up and distribute material around. These two monsters should be the most spectacular X-ray in terms of sight, but a new study uses ideas from the NuSTAR (Nuclear Muscle Nuclear Surgeon Security) mission; show that there is a much smaller thing and a competition with the two lies.


The most spectacular features of Whirlpool galaxy – officially officially M51a – are the two "long" arms full of stars that crawl around the galactic center as ribbons. The M51b is much smaller and goes to the bottom of the page; Whirlpool In conjunction with the M51, the two galaxies come together.

At the center of each galaxy millions of black holes are higher than the Sun. The clever unity should be pushed large amounts of gas and dust into these black holes and into the orbit around them. As a result, severe intimidation of the dark holes should cause the orbiting material to heat up and to; move, and create clear diagrams around each one who is in a position; All the stars can be donated in their galaxies.

But black hole does not have such a clear movement in the X-ray range as scientists expected through a combination. Based on earlier inspections of the solvent energy solvents, such as NAS Observatra Chandra X-ray NASA, scientists thought that there were lines of gas and dust around the black hole in the galaxy larger than & # 39; additional exclusion. But the new study, published in Icon for Astrophysical, using the NuSTAR high-energy X-ray vision to co-peers below these lines and find that the black hole is still less than expected.

"I'm still amazed at this look," said the executive author, Murray Brightman, a researcher at Caltech in Pasadena, California. "Galactic decisions are expected to become a black hole, and that the evidence will result strongly from high-tech x-ray. But we do not see that here. "

Brightman believes that black holes are most likely to be "broken" when they are " join together rather than simply move less or more sustainable through the process.

"It's a new idea in a downstream idea," said Daniel Stern, a research scientist at the NAS Propulsion Laboratory NASA in Pasadena and science the NuSTAR project. "We thought the black hole change was on millions of scales of years, but now we think these timescales could be much shorter. A & # 39; determine how short a range of active research is. "

Little but brilliant

Together with the two black ears that reduce less than expected scientists in M51a and M51b, the former one also has a & # 39; Given what millions of times are smaller than the two black holes that still have an intense shine. The two evidence is not connected, but they will create an amazing X-ray landscape in M51.

The X-ray star is a neurone star, a huge bunch of material that is available; disappeared after a big star was hit at the end of his life. The current Neodronic star is hundreds of miles of smaller journeys in a diameter than just Sun as wide as a city – but there is one or two of them. most. There would be a weight of more than one billion billion in a teaspoon of neutron reel material.

Despite their size, neutral stars often make themselves known through lightweight light. The neutron star is found in M51 even more beautiful than usual and it is the responsibility of a new class named as ultraluminous neutron stars. Brightman said that some scientists have suggested that strong magnetic fields that have created the neutron reel can be accountable for the purpose of releasing the atmosphere; a previous paper with Brightman and colleagues about this neutron star supports this opinion. Some of the clear, high-energy X-ray sources seen in these two diseases may be neutral stars.
