New Data Helps Astronomers Piece Together the Evolution of Supermassive Black Holes

March 27, 2014

0 Comments

Using data from NASA’s Wide-field Infrared Survey Explorer, astronomers are piecing together the evolution of supermassive black holes. How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA’s Wide-field Infrared […]

Neutron Stars and Their Similarities with Black Holes

March 25, 2014

1 Comment

New research shows the similarities that neutron star have with black holes. For astrophysicists neutron stars are extremely complex astronomical objects. Research conducted with the collaboration of SISSA and published in the journal Physical Review Letters demonstrates that in certain respects these stars can instead be described very simply and that they show similarities with […]

Researchers Model the Workings of an X-ray Binary Star

March 14, 2014

0 Comments

Using ten years’ worth of optical, infrared and X-ray data on LMC X-3, astronomers developed a model that can successfully explain the workings of an X-ray binary star. The bright X-ray source known as LMC X-3 resides in the Large Magellanic Cloud, the dwarf galaxy that is the Milky Way’s nearest neighbor. Two decades ago […]

Researchers Study Mysterious Gamma Ray Source with No Known Counterpart

February 28, 2014

0 Comments

Using the VERITAS gamma-ray telescope, astronomers studied a mysterious VHE gamma-ray source from the constellation of Cygnus that has no known counterpart at other wavelengths. Gamma-rays are the most energetic known form of electromagnetic radiation, with each gamma ray being at least one hundred thousand times more energetic than an optical light photon. The most […]

Researchers Trace the Evolution of Galaxies that Host Massive Black Holes

February 25, 2014

0 Comments

A newly completed statistical study of the optical and infrared properties of 330,811 galaxies traces the evolution of galaxies that host massive black holes. Our Milky Way galaxy, like most galaxies, has a nucleus with a massive black hole. Our nuclear black hole contains about four million solar masses of material, but others are thought […]

RXTE Satellite Exposes the Cloudy Cores of Active Galaxies

February 20, 2014

0 Comments

Using RXTE satellite data, researchers have revealed a dozen instances where X-ray signals from active galaxies dimmed as a result of a cloud of gas moving across our line of sight, tripling the number of cloud events previously identified in the 16-year archive. Picture a single cloud large enough to span the solar system from […]
