This is one slice through the map of the large-scale structure of the Universe from the Sloan Digital Sky Survey and its Baryon Oscillation Spectroscopic Survey. Each dot in this picture indicates the position of a galaxy 6 billion years into the past. The image covers about 1/20th of the sky, a slice of the Universe 6 billion light-years wide, 4.5 billion light-years high, and 500 million light-years thick. Color indicates distance from Earth, ranging from yellow on the near side of the slice to purple on the far side. Galaxies are highly clustered, revealing superclusters and voids whose presence is seeded in the first fraction of a second after the Big Bang. This image contains 48,741 galaxies, about 3% of the full survey dataset. Grey patches are small regions without survey data. (Image credit: Daniel Eisenstein and the SDSS-III collaboration)

The rectangle on the far left shows a cutout of 1000 sq. degrees in the sky containing nearly 120,000 galaxies, or roughly 10% of the total survey. The spectroscopic measurements of each galaxy — every dot in that cutout — transform the two-dimensional picture into a three-dimensional map, extending our view out to 7 billion years in the past. The brighter regions in this map correspond to the regions of the Universe with more galaxies and therefore more dark matter. The extra matter in those regions creates an excess gravitational pull, which makes the map a test of Einstein’s theory of gravity. (Image credit: Jeremy Tinker and the SDSS-III collaboration)

Future particle colliders will require highly efficient acceleration methods for both electrons and positrons. Plasma wakefield acceleration of both particle types, as shown in this simulation, could lead to smaller and more powerful colliders than today’s machines. (F. Tsung/W.

Simulation of high-energy positron acceleration in an ionized gas, or plasma – a new method that could help power next-generation particle colliders. The image shows the formation of a high-density plasma (green/orange color) around a positron beam moving from the bottom right to the top left. Plasma electrons pass by the positron beam on wave-like trajectories (lines). (W. An/UCLA)

Computer simulations of the interaction of electrons (left, red areas) and positrons (right, red areas) with a plasma. The approximate locations of tightly packed bundles of particles, or bunches, are within the dashed lines. Left: For electrons, a drive bunch (on the right) generates a plasma wake (white area) on which a trailing electron bunch (on the left) gains energy. Right: For positrons, a single bunch can interact with the plasma in such a way that the front of the bunch generates a wake that accelerates the bunch tail. (W. An/UCLA)

Neutrinos can transform into one another, and so can quarks. What about muons and electrons? The Mu2e experiment will allow scientists to produce and capture muons, then search for signs that they convert into electrons. The Mu2e prototype magnet coil underwent testing in the Central Helium Liquefier at Fermilab.

Illustration of the possible layout of the quarks in a pentaquark particle such as those discovered at LHCb. The five quarks might be tightly bonded (left). They might also be assembled into a meson (one quark and one antiquark) and a baryon (three quarks), weakly bound together. (Courtesy: CERN)

Conventional theories predict that dark matter particles would not collide, rather they would slip past one another (above). Hochberg et al. predicts dark matter SIMPs would collide and interact with one another (below). (Credit: Kavli IPMU)
