Sentences with phrase «dense gas disks»

These observation results were published as Izumi et al. «Do Circumnuclear Dense Gas Disks Drive Mass Accretion onto Supermassive Black Holes?»

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.

The increased sensitivity and improved resolution of the EVLA will let scientists peer deep into star - forming clouds and spy on protoplanetary disks of dense gas surrounding young stars as well as track supernovae, fast - moving neutron stars and black holes, McKinnon says.

But in the inner disk, warm gas would fight against the planet's weak gravity, so the cold and dense gas of the outer disk is the more likely womb.

Such disks have lost all of their gas and are far less dense than the ones around younger stars.

According to researchers, the debris from this collision formed a very wide disk around Mars, made up of a dense inner part composed of matter in fusion, and a very thin outer part primarily of gas.

Using an unusual configuration of radio telescopes to detect particles the size of pebbles, Greaves found a dense clump in the disk of gas and dust surrounding the star.

After carefully examining several possibilities, the team concluded that huge amounts of gas are rapidly falling onto «little monster» black holes in each of these ULXs, which produces a dense disk wind flowing away from the supercritical accretion disk.

When dense regions of a cloud collapse, the massive inner part becomes a star while the rest forms a swirling disk of gas and dust that may give rise to planets.

«Dense molecular gas disks drive the growth of supermassive black holes: Are supernova explosions the key?.»

The joint research team led by graduate student and JSPS fellow Takuma Izumi at the Graduate School of Science at the University of Tokyo revealed for the first time — with observational data collected by ALMA (Atacama Large Millimeter / submillimeter Array), in Chile, and other telescopes — that dense molecular gas disks occupying regions as large as a few light years at the centers of galaxies are supplying gas directly to the supermassive black holes.

When stars form, they are encircled by dense regions of gas and dust called protoplanetary disks, from which planets form.

Astronomers have known for some time that certain black holes were surrounded by thick, dense disks of gas and dust called tori.

Around the accretion disk are relatively dense clouds of hot gas that could be responsible for the broad emission lines seen in Type 1 Seyferts.

Some, like the Milky Way, are flat disks with arcing spiral arms and regions of dense interstellar gas, called nebulae, which are active sites of star formation.

Strong turbulence caused by supernova explosions inside a dense molecular gas disk in the central region of a galaxy disturbs the stable motion of gas.

However, it is impossible to measure the amount of dust and gas in the densest part of the disk by near - infrared observations.

While Kraan - Korteweg's work over her career has dug up some 5,000 galaxies in the Vela Supercluster, she is confident that a sensitive enough radio survey of this neutral hydrogen gas will triple that number and reveal structures that lie behind the densest part of the Milky Way's disk.
