Searching for Giant Planets Around Baby Stars
How long does planetary migration take? Crockett et al. look for the answer by searching for hot Jupiters around extremely young stars.
Observational Signatures of Accretion Induced Collapse of White Dwarfs
A massive white dwarf accreting from a companion can lead to accretion induced collapse turning the white dwarf into a neutron star – how can such an event be observed?
A deep X-ray observation of Hickson Compact Group 62
Rafferty et al. study the effect of radio jets on the intracluster gas in Hickson Compact Group 62.
How to Avoid Cosmic Variance in Your Cosmological Survey
To accurately model the universe, we need large surveys of its content and behavior. But how can we be sure that our surveys are a representative snapshot of the universe as a whole? In this post we tackle the problem of cosmic variance.
Into the Void
Voids in the cosmic web are observed to be contain large-scale magnetic fields … but it’s unclear how this happens. In this paper, the authors suggest two possible explanations.
Finding the source of the Universe’s infrared glow
New observations at infrared background find a mysterious background glow on the sky, which is inconsistent with the previously proposed models for its origin. The authors suggest that the infrared glow could be coming from rogue stars that have been expelled from host galaxies out into the dark matter halos that surround galaxies.
