Sentences with phrase «result in supernovae»

They are abundantly produced in supernova explosions, star - powering nuclear fusion and other nuclear processes, resulting in trillions of neutrinos passing through us every minute.
The results, presented April 15 at a conference in Geneva, may force scientists to rethink theories that focus on supernovas as the producers of these speedy particles.
The astronomers, who published their results in The Astrophysical Journal, hope such observations will help them understand supernovae, which are important because the blasts are thought to create heavy elements such as silver, nickel, and copper.
When a low - energy neutrino or antineutrino from a supernova collides with a water molecule in the tank, the resulting light signal is recorded by about 100 of 13,000 photomultipliers, ultrasensitive light - detecting devices that turn a tiny flash of light into a larger recordable burst of electricity.
When it comes time for one to end it all in a supernova, there isn't as much matter left to collapse in on itself, resulting in a lower - mass black hole.
And gamma - ray bursts — thought to result from especially powerful supernovas or stellar collisions — are so rare that the researchers calculated that, over a billion years, there's only about a 1 in 3 billion chance of one killing off tardigrades.
Kirby's team observed Segue 2 with the Keck telescope in Hawaii and found that it has the chemical composition of a galaxy that has hosted several supernovae and kept hold of the resulting debris (The Astrophysical Journal, doi.org/mtq).
«Some stars get the boot when their companion star explodes in a supernova, and others can get kicked out of crowded star clusters,» says William Chick, a UW doctoral student in physics, who presented his team's new results Jan. 5 at the 227th American Astronomical Society meeting in Kissimmee, Fla. «The gravitational boost increases a star's speed relative to other stars.»
The property results from the way they form: When a giant star runs out of fuel and can no longer fight against the crushing force of its gravity, its core shrinks to the size of an asteroid, and most of its mass is blasted away in a titanic explosion called a supernova.
The team will repeatedly bombard the target with the same type of ion to build a picture of the different energy levels in the resulting atoms, helping to predict the stabilities of the exotic forms made in supernovae.
The team also succeeded in explaining, with a theoretical model, that the actual changes (balance of inflow and outflow) in gas levels they observed were the result of the increasing amount of gas falling into the supermassive black holes within the gas disks enhanced by strong turbulence generated by supernova explosions (an activity associated with star formation) when a star inside the dense gas disks dies.
According to Kool the results coming from SUNBIRD reveal that their new approach provides a powerful tool for uncovering core - collapse supernova in nuclear regions of galaxies.
We present the first results of project SUNBIRD (Supernovae UNmasked By InfraRed Detection), where we aim to uncover CCSNe that otherwise would remain hidden in the complex nuclear regions of LIRGs, and in this way improve the constraints on the fraction that is missed by optical seeing - limited surveys.
In this, the first results of the SUNBIRD project, the team discovered three core - collapse supernovae, and one possible supernova that could not be confirmed with subsequent imaging.
This animation illustrates how the powerful gravity of a massive galaxy cluster bends and focuses the light from a supernova behind it, resulting in multiple images of the exploding star.
The explosive (or eruptive) variables include novas, supernovas, and similar stars that undergo sudden outbursts of radiant energy, which results in rapid brightening.
The top candidates, the astronomers suggested, are a neutron star, possibly a highly - magnetic magnetar, surrounded by either material ejected by a supernova explosion or material ejected by a resulting pulsar, or an active nucleus in the galaxy, with radio emission coming from jets of material emitted from the region surrounding a supermassive black hole.
Observing the spiral galaxy M100, Kieron studied a supernova in the galaxy, and his results can be seen in the coursework here.

For many years, astronomers have known two types - «supermassive» black holes at the centers of large galaxies and the so - called «stellar - mass» black holes that result when a star about 10 times the Sun's mass ends its life in a supernova explosion.
Some of the new results included deeper understandings of galaxies in the distant universe, more complete pictures of the massive galaxy clusters, and the searches for exploding massive stars, called supernovae.
