Scientists Reformulate Their Knowledge Of Dark Matter

For decades, the mystery of Dark Matter has been at the forefront of physics research. Since the 1930s, scientists have been aware that all of the mass that we can see – the stars, the dust, the planets, and black holes – makes up only 20 percent of the Universe.

According to astrophysicists, dark matter is the key to understanding the universe as it comprises 85 percent of all mass found in it and is suspected to have caused the growth of galaxies.

Using the ESA’s XMM-Newton and NASA’s Chandra X-ray Observatory, astronomers have located a mysterious X-ray signal that could be produced by sterile neutrinos – particles that are a potential candidate for the abundant and essentially invisible substance known as dark matter.

Galaxies are not as isolated as they at first glance may seem; on a cosmic scale they congregate in clumps along with dark matter and hot gas.

Neighboring Satellite Dwarf Galaxies Do Not Fit The Standard Model

An international team of scientists have found that dwarf satellite galaxies that orbit the Milky Way and neighboring Andromeda galaxy defy the standard model of galaxy formation.

Looking For Evidence Of The Double Nature Of Neutrinos
2014-06-05 03:26:43

Neutrinos are tiny, neutral elementary particles that, contrary to the standard model of physics, have been proven to have mass. One possible explanation for this mass could be that neutrinos are their own antiparticles, so-called Majorana particles.

A decades-old theory used by astronomers to explain the varying appearances of supermassive black holes is being called into question in the wake of new data obtained using NASA's Wide-field Infrared Survey Explorer.

What do you get when you combine polarized radiation with Einstein's theory of general relativity? According to a group of astrophysicists at UC San Diego, you just might get more accurate estimates for the mass of ghostly subatomic particles known as neutrinos.

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

The Bullet Cluster is made up of two colliding clusters galaxies. According to a 2006 study, the Bullet Cluster also shows the best evidence for the existence of Dark Matter. From observations of galaxy cluster collisions it has been found that many show displacement between their center of visible matter and their gravitational potential. Each component, stars, gas, and dark matter, within a cluster pair behaves differently during a collision allowing for each to be studied separately....

The Abell 520 galaxy cluster is an strange structure formed by a major merger. Due to its odd and chaotic nature it has been given the nick-name the Train Wreck Cluster. The Dark Matter within the cluster does not act as expected like it does in other clusters, therefore, Abell 520 creates problems for many of the prevailing theories about Dark Matter. It also disrupts many alternative theories of modified gravity. Similar to the Bullet Cluster the gas contents and galaxies within the...

The cluster CL0024+17, located in Pisces, is a galaxy cluster that is allowing astronomers to probe the distribution of dark matter in space. Dark matter does not reflect light and therefore cannot be seen. It is only detectable by the way its gravity affects the lights around it. Using gravitational lensing astronomers observe the distorted light around the dark matter and are able to tell where it is located within a cluster. A dark matter ring found near the cluster's center, by...
