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!

  • 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.

Overview

The Gravitational Astrophysics Laboratory (Code 663) conducts a broad range of scientific investigations into astrophysical regimes dominated by extreme gravity. The laboratory provides the scientific and technical leadership to develop space-based gravitational wave observatories and includes a mix of theorists and experimentalists. Research encompasses a variety of areas, including numerical relativity, gravitational-wave sources and data analysis, mission formulation, theoretical modeling of high energy astrophysical sources, and precision metrology.
