Researchers have discovered the largest radio jet yet at a redshift of z > 4, spanning a distance of 215,000 light-years; this discovery also shows that even low-mass black holes can produce powerful jets.
A comprehensive survey of the extensive filamentary nebula that surrounds the central galaxy of the Perseus Cluster affirms previous suggestions that magnetic fields play an important role in the life of the nebula.
By calculating general relativistic corrections, researchers show that the gravitational wave strain from a rotating neutron star with a mountain is 12% greater than when relativity is not taken into account.
Kiladze, a structure on the surface of Pluto that was first noted for its water-ice-dominated composition, may be the caldera of a cryovolcano; the region shares certain properties with other cryovolcanoes on Pluto.
Using a telescope suited to the study of crowded star fields, researchers have produced a 10,971,906-object catalog of stars toward the Small Magellanic Cloud.
The angular momentum of inflowing gas appears to be correlated with the strength of an active black hole’s jet, simulations show, and this may be consistent with the behavior of the Milky Way’s supermassive black hole.
