Void cosmology
The distribution of matter in the Universe has much to say about its constituents and evolution. Can the distribution of voids also help us understand the Universe?
Piecing together the Hubble constant
Different methods of measuring the Hubble constant yield slightly different values, but they are still in reasonable agreement.
Astrophysical Classics: Cosmochronology with White Dwarfs
In today’s Astrophysical Classic, we hark back to 1987 and the introduction of a new method determining the age of the universe through the use of white dwarf stars.
Something from Nothing: Simulating our Universe
High resolution computational simulations are a valuable means by which Astronomers test our understanding of the Universe, and make predictions. The world of computational astrophysics broke new ground recently with the highest resolution cosmological simulation to date, Illustris, making for some spectacular science and some spectacular images.
Filling the redshift gap with carbon monoxide mapping
Can we find galaxies using the light emitted by their star forming regions? The authors of this paper explore a technique that would allow us to reach relatively unexplored epochs of the Universe.
To the Center of The Cold Spot
Astronomers measure the randomness in the Cosmic Microwave Background radiation to determine the cause of an anomalously cold spot.
