Construction and commissioning of the cubic-kilometer IceCube neutrino detector and its low energy extension DeepCore have been completed. The instrument detects neutrinos over a wide energy range: from 10 GeV atmospheric neutrinos to 1010 GeV...

ABSTRACT: A hierarchy of atmospheric models of increasing complexity is essential to attempts at understanding the Earth's climate and future climate change. Some examples of elements of this hierarchy and examples of their use will be provided...

ABSTRACT: Magnetic reconnection is a phenomenon of nature in which magnetic field lines change their topology in plasma and convert magnetic energy to particles by acceleration and heating. It is one of the most fundamental processes at work in...

ABSTRACT: Neutral atomic hydrogen is by far the most abundant element in galaxies. Although reasonably complete images of the HI sky exist out to redshifts of 0.08, we know surprisingly little about the HI properties of galaxies at larger...

ABSTRACT: Recent lessons learned from exploring bulk compositions and atmospheres of solid planets and the prospects to connect them to experiments in alternative biochemistries.

ABSTRACT: A fundamental challenge in cosmology and galaxy evolution is to understand how dark matter (DM) haloes influence the galaxies that form inside them. Unfortunately, the parts of this process that we can simulate well—the growth of DM...

ABSTRACT: Reionization was the last major phase transition for most of the normal matter in the universe, and a landmark event in the early phases of galaxy formation. Lyman alpha emission from galaxies provides a good tool for probing...
