Caltech's Cosmic Web Imager Directly Observes "Dim Matter"
2014-04-30 03:53:16

Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM)—the diffuse gas that connects galaxies throughout the universe—with the Cosmic Web Imager, an instrument designed and built at Caltech.

Gravitational Lensing In The Unusual "Magatama" Galaxy

In a course of studying young galaxies at a distance of 11.6 billion light years from Earth, a team of astronomers noticed a strangely shaped galaxy that looks like a "magatama", an ancient, comma-shaped Japanese amulet made of stone.

Crowded Star Clusters Defy Simple View Of Gravity

On large astronomical scales, gravity remains the dominant force acting on heavenly bodies. But when it comes to young clusters of stars, researchers say these crowded environments cannot be fully accounted for by a simple view of gravity.

The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick.

Even though it was discovered by a Dutch primary school teacher it’s not a fairytale, in fact, it’s a "cosmic ghost" that could possibly represent a new class of astronomical objects.

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
