The Astrophysical Journal is a peer-reviewed scientific journal covering astronomy and astrophysics. It was founded in 1895 by the American astronomers George Ellery Hale and James Edward Keeler. It publishes three 500-page issues per month. Since 1953, The Astrophysical Journal Supplement Series has been published in conjunction with The Astrophysical Journal. It aims to supplement the material in the journal. It publishes six volumes per year, with two 280-page issues per volume. The journal and the supplement series were both published by the University of Chicago Press for the American Astronomical Society. In January 2009 publication was transferred to Institute of Physics Publishing, following the move of the society s Astronomical Journal in 2008. The reason for the changes were given by the Society as the increasing financial demands of the Press. The Astrophysical Journal Letters is another section of The Astrophysical Journal intended to publish rapid communications.

Black holes stunt growth of dwarf galaxies

Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies ...

The clumpy and lumpy death of a star

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond ...

Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this ...

Not long ago, the center of the Milky Way exploded

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the centre of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the Galaxy and ...

Heating the solar corona

The hot outer layer of the sun, the corona, has a temperature of over a million degrees Kelvin, much more than the surface temperature of the Sun which is only about 5500 degrees Kelvin. Moreover, the corona is very active ...

Many gas giant exoplanets waiting to be discovered

There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA's WFIRST space telescope, according to new models of gas giant planet formation ...

Oldest galaxy protocluster forms 'queen's court'

Using the Subaru, Keck and Gemini Telescopes, an international team of astronomers has discovered a collection of 12 galaxies that existed about 13.0 billion years ago. This is the earliest protocluster ever found. One of ...
