Lecture: John Carlstrom – What Do We Know About The Big Bang?

John Carlstrom gives the plenary lecture at the New Horizons in Inflationary Cosmology Templeton Conference organized by the Stanford Institute for Theoretical Physics.

Our understanding of the origin, evolution and make-up of the Universe has undergone dramatic and surprising advances over the last decades. Much of the progress has been driven by measurements of the fossil light from the big bang, called the cosmic microwave background radiation, which provides us with a glimpse of the Universe as it was 14 billion years ago. This talk will discuss what we know about the Big Bang and how we learned it. We will also talk about the new questions we are asking about the origin of the Universe and the experiments being pursued to answer them, peering back to the beginning of time.

Possible signature of dark matter annihilation detected

A false-color image of the anomalous gamma-ray emission from the central region of the Milky Way galaxy; this emission is suspected of coming from dark matter annihilation. In this image, the emission from conventional sources has been subtracted from the total. The region covers roughly five degrees; the brightest emission is colored red and faintest blue.

CfA astronomer Doug Finkbeiner and a team of colleagues claim to have identified just such a signature of dark matter annihilation.

Caught in the act | ESA/Hubble

The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense gravity is warping the supernova’s light.

Fermi Telescope Caps First Year With Glimpse of Space-Time (w/ Video)

This view of the gamma-ray sky constructed from one year of Fermi LAT observations is the best view of the extreme universe to date. The map shows the rate at which the LAT detects gamma rays with energies above 300 million electron volts — about 120 million times the energy of visible light — from different sky directions. Brighter colors equal higher rates. Credit: NASA/DOE/Fermi LAT Collaboration.

Earth might have hairy dark matter

The solar system might be a lot hairier than we thought. A new study publishing this week in the Astrophysical Journal by Gary Prézeau of NASA’s Jet Propulsion Laboratory, Pasadena, California, proposes the existence of long filaments of dark matter, or “hairs.”

Fermi mission finds hints of gamma-ray cycle in an active galaxy

Fermi mission finds hints of gamma-ray cycle in an active galaxy

Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called “active” galaxy, whose emissions are powered by a supersized black hole. If confirmed, the discovery would mark the first years-long cyclic gamma-ray emission ever detected from any galaxy, which could provide new insights into physical processes near the black hole.
