Congratulations to Charles Bennett, Gary Hinshaw, Norman Jarosik, Lyman Page Jr., David Spergel and the WMAP Science Team for winning the 2018 Breakthrough Prize in Fundamental Physics

Congratulations to Charles Bennett, Gary Hinshaw, Norman Jarosik, Lyman Page Jr., David Spergel and the WMAP Science Team for winning the 2018 Breakthrough Prize in Fundamental Physics on Dec. 3! The citation reads: “For detailed maps of the early universe that greatly improved our knowledge of the evolution of the cosmos and the fluctuations that seeded the formation of galaxies.” The Breakthrough Prize in Fundamental Physics was founded in 2012 by Yuri Milner to recognize those individuals who have made profound contributions to human knowledge. The team also includes:

Chris Barnes, Olivier Doré, Joanna Dunkley, Ben Gold, Michael Greason, Mark Halpern, Robert Hill, Al Kogut, Eiichiro Komatsu, David Larson, Michele Limon, Stephan Meyer, Michael Nolta, Nils Odegard, Hiranya Peiris, Kendrick Smith, Greg Tucker, Licia Verde, Janet Weiland, Ed Wollack, and Ned Wright

Congratulations to the many ASD members who were involved in the exciting gravitational wave and electromagnetic counterpart discovery of merging neutron stars, and the subsequent media activity around the discovery!

Congratulations to the Astrophysics Science Division scientists who are PIs and Co-Is on the recently announced Astrophysics Missions of Opportunity and Medium-Class Explorer missions!

  • ISS-TAO (Transient Astrophysics Observer on the ISS), a Mission of Opportunity proposal submitted to the 2016 Explorer opportunity, was selected for a Phase A study. ISS-TAO team members include PI Jordan Camp (663), Scott Barthelmy (661), Rob Petre (662), Judy Racusin (661), Brad Cenko (661), Frank Marshall (661), Jeremy Schnittman (663), Andy Ptak (662), and Amy Lien (661), Leo Singer (661), and Tod Strohmeyer (662). ISS-TAO is a wide-field X-ray transient detector aboard the International Space Station that would observe numerous events per year of X-ray transients related to compact objects. The mission’s primary goal is the detection of X-ray counterparts to gravitational waves produced by neutron stars merging with black holes and other neutron stars. Other targets would be supernova shocks, neutron star bursts, and high redshift gamma-ray bursts.
  • Rob Petre (662), Andy Ptak (662), Alan Smale (660), and Lynne Valencic (662) are co-Is on Arcus (PI Randall Smith, SAO), selected as a concept study for a Medium-Class Explorer mission. Arcus would study stars, galaxies and clusters of galaxies using high-resolution X-ray spectroscopy to characterize the interactions between these objects and the diffuse million-degrees gas that surrounds and permeates them.
  • Alan Smale (660) and Terri Brandt (661) are collaborators on COSI-X (PI Steve Boggs/UCB), selected as a concept study for an Explorer Mission of Opportunity. COSI-X is a balloon-borne, wide-field-of-view telescope designed to survey the gamma-ray sky at 0.2-5 MeV, performing high-resolution spectroscopy, wide-field imaging, and polarization measurements. COSI-X would map gamma-rays from antimatter around the Milky Way's center, as well as from newly-formed radioactive elements in the debris of stellar explosions.

The Astroparticle Physics Laboratory conducts research in cosmic ray and gamma ray high-energy astrophysics. Researchers investigate high-energy phenomena in the universe in terms of unified theories of fundamental interactions. The Laboratory conducts a broad range of space-based scientific studies of the origin, nature, and effect of cosmic rays. Researchers also observe gamma radiation that carries the signatures of physical processes at work throughout the universe. The birth and evolution of black holes and other compact objects is a key area of investigation. The Laboratory emphasizes the development of new detectors and instrumentation technologies.
