Emergent Gravity faces its First Test in Galaxy Lensing
A recently proposed theory of gravity that got the astrophysical community’s attention is put to tests by observations. Does it succeed? Let’s find out!
The Bullet Cluster – A Smoking Gun for Dark Matter!
A classic paper on dark matter is brought to ‘light’ in this bite, discussing a discovery that provides one of the best evidences we have for non-baryonic matter in the universe.
Tying the knot with galaxy clustering
Star formation rate and stellar mass as telltales of dark matter and galaxy connection.
Like a Rolling Coin: How Stars Trace Out The Dark Matter Surrounding Us
As smaller galaxies collide with our own they’re slowly torn apart. By watching how they spread across the night’s sky we can infer an incredible amount about the shape of the galaxy and the nature of dark matter.
The Darkest Galaxies
Astronomers have recently discovered a number of galaxies made almost entirely of dark matter. Today’s astrobite takes a closer look at one of them.
Particlebites reports on possible dark matter signatures from the Galactic center
In the latest post on our sister site Particlebites, Chris Karwin writes about new observations of the gamma ray excess at the Galactic center from Fermi.
