X Marks the Spot, said the Gamma Ray
A Fermi/LAT study of the ISM using gamma rays finds evidence for missing gas and variations in the CO-to-molecular gas conversion factor.
Disappearing act: how gamma-ray bursts help us find massive reservoirs of neutral hydrogen
Using a combination of spectra from gamma-ray burst afterglows and photometry and spectroscopy of nearby objects, astronomers have found the galaxy counterpart to at least one high-redshift absorption system, bumping the total number of such galaxies from nine to ten.
Snow Lines and Protoplanetary Disks, Or, Where’d All The Water Go?
Planet formation theory predicts a water-rich Earth. On a comparative basis, the Earth is water-poor. This paper aims to reconcile theory and observation.
Searching for Signatures of Pair-Instability Supernovae
Scientists search for signatures of pair-instability supernovae in thousands of Sloan Digital Sky Survey Stars.
First GASPs of Star Formation in Taurus
The well-known constellation Taurus is home to many young stars, and the details of star formation are explained by observing far-infrared radiation from several of these objects with the Herschel space observatory.
How to use DNA to search for dark matter
Can DNA be used to detect dark matter? Guest author Elisa Chisari explains how biology and physics can combine to teach us more about the universe.
