Sentences with phrase «by infalling»

The white blob at the center contains a massive black hole surrounded by infalling material, which, oddly, is not much brighter than some of the stars around it.

Quasars constitute a brief phase in the galactic life - cycle, during which they shine as the most luminous objects in the Universe, powered by the infall of matter onto a supermassive black hole.

Messier 108 also contains H1 supershells, shells of expanding gas driven either by bursts of star formation and the resulting supernova explosions, or by infall of gas from outside the galaxy, or possibly by radio jets.

Not exact matches

One possible solution, proposed in 2007 by physicists Patrick Hayden of Stanford University and John Preskill of Caltech, is that the black hole could act like a mirror, with information about infalling particles being reflected outward, imprinted in the Hawking radiation.

Crucially, the observed amount of infall is explained well by the predictions of general relativity.

Gottesman and colleague John Preskill of the California Institute of Technology in Pasadena, US, found that previous calculations by other researchers using this model allowed information to escape for only certain interactions between the infalling matter and the infalling Hawking radiation.

Supermassive black holes like the one in galaxy M87 probably grow not only by feeding on infalling gas and stars but also by mergers of smaller black holes.

Olsen thinks the infalling gas hit 30 Doradus, causing it to grow large and luminous by fueling the formation of new stars.

Astronomers have long suspected that the young, 12 - million - year - old star hosts a massive planet, since it is surrounded by a dusty disc of debris thought to be created by the collision of rocky bodies and infalling comets.

During this phase, some infalling gas was swallowed by the black hole, while the remaining was pumped out at a breakneck speed of nearly 2 million miles per hour.

These observational results were published in The Astrophysical Journal as Takakuwa et al. «Angular Momentum Exchange by Gravitational Torques and Infall in the Circumbinary Disk of the Protostellar System L1551 NE» in November 2014.

N ~ 2 seen in the spiral arms in M81 and M101 supports the scenario of star formation triggered by cloud - cloud collisions enhanced by spiral density wave, while N ~ 1 derived in giant HII regions in M101 suggests the star formation induced by the Parker instability triggered by high velocity HI gas infall.

Many of the mechanisms are like that — the tides, the direct inductive heating, the heating caused by the days influx of falling meteorites — which incidentally is far greater than the rate of heat loss through outgassing, as meteoric dust and matter infalls at an average rate of at least millimeters per decade, from my own direct measurements — they have «impressively» large amounts of annual energy associated with them, right up to where you divide by the surface area of the earth and the number of seconds in a year.
