is black hole a remnant of a supernova

van Loon, J. C. Wheeler and Giovanna Zanardo, 19 November 2019, The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.Email address is optional. An explanation of cosmic X-ray sources, from black holes to galaxy clusters, as well as a review of the history of X-ray astronomy, what X-rays are and how they are produced. This is a list of observed supernova remnants (SNRs) in the Milky Way, as well as galaxies nearby enough to resolve individual nebulae, such as the Large and Small Magellanic Clouds and the Andromeda Galaxy.. Supernova remnants typically only survive for a few tens of thousands of years, making all known SNRs fairly young compared to many other astronomical objects. Extremely high-resolution images revealed a hot “blob” in the dusty core of SN 1987A, which is brighter than its surroundings and matches the suspected location of the neutron star.“We were very surprised to see this warm blob made by a thick cloud of dust in the supernova remnant,” said Mikako Matsuura from Cardiff University and a member of the team that found the blob with ALMA. “The supernova’s neutrino signal suggested that a black hole never formed, and moreover it seems difficult for a black hole to explain the observed brightness of the blob. The green and blue hues reveal where the expanding shock wave from the exploded star is colliding with a ring of material around the supernova. Credit: NRAO/AUI/NSF, B. SaxtonEver since astronomers witnessed one of the brightest explosions of a star in the night sky, creating Extremely high-resolution ALMA images revealed a hot “blob” in the dusty core of Supernova 1987A (inset), which could be the location of the missing neutron star. It was like a modern holy grail.”The theoretical study by Page and his team, published today in These predictions were the location and the temperature of the neutron star. The green represents the glow of visible light, captured by NASA’s Hubble Space Telescope. That’s why we suggested that there is a neutron star hiding inside the dust cloud.”Even though Matsuura and her team were excited about this result, they wondered about the brightness of the blob. “There has to be something in the cloud that has heated up the dust and which makes it shine. A teaspoon of its material would weigh more than all the buildings within New York City combined. The blue color reveals the hottest gas and is based on data from NASA’s Chandra X-ray Observatory. We compared all possibilities and concluded that a hot neutron star is the most likely explanation.”Supernova 1987A resides 163,000 light-years away in the Southern Sky in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Both diagrams show a part of the shock front produced by the expansion of the supernova remnant W44. The black hole, found lurking about 10,000 light-years away in the gas cloud of the supernova remnant W44, is believed to be just one of the millions peppered throughout our cosmic neighborhood. “We thought that the neutron star might be too bright to exist, but then Dany Page and his team published a study that indicated that the neutron star can indeed be this bright because it is so very young,” said Matsuura.Dany Page is an astrophysicist at the National Autonomous University of Mexico, who has been studying SN 1987A from the start. The expanding cloud of material left over from the supernova now appears approximately 10 light-years (3 pc) across from Earth's perspective. “Its kinetic energy is a few tens of times larger than that injected by the W44 supernova.

The ring was initially made to glow by the flash of light from the original explosion.
