X4.00001: Gamma-ray and X-ray views of the energetic sky from a multimessenger perspective Invited Speaker: Elizabeth Hays High-energy space observatories have an established history of opening new windows on the energetic universe. Recent observations in the X-ray and gamma-ray domains have revealed new source classes and phenomena that challenge and extend ideas about the sites and properties of astrophysical particle accelerators. As observations of neutrinos, cosmic rays, and gravitational waves become more sensitive, they provide an increasingly important source of information for answering some of the open questions being explored using X-ray and gamma-ray telescopes. Multimessenger studies also promise opportunities to generate questions that photon studies alone have not been able to ask. This talk will review the current gamma-ray and X-ray views of the energetic sky with a focus on interesting areas for multimessenger research. [Preview Abstract] |

X4.00002: Current and Future Cosmic Ray Observatories in Space Invited Speaker: Eun-Suk Seo Balloon-borne and space based instruments configured with particle detectors have been flown to study cosmic-ray origin, acceleration and propagation. They have also been used to search for exotic sources, such as dark matter and antimatter, and to explore a possible limit to particle acceleration in supernova. A challenge of these experiments for high energies is that the detectors must be large enough to collect adequate statistics, yet stay within the weight limit available for space/balloon flight. Innovative approaches now promise high quality measurements over an energy range that was not previously possible, particularly as the International Space Station becomes available for utilization. Recent results will be reviewed, and the outlook for existing and future experiments will be discussed. [Preview Abstract] |

X4.00003: The Science of Gravitational Waves with Space Observatories Invited Speaker: James Thorpe After decades of effort, direct detection of gravitational waves from astrophysical sources is on the horizon. In addition to providing insight about gravity itself, gravitational waves hold immense promise as a tool for general astrophysics. In this talk I will provide an overview of the science enabled by a space-based gravitational wave observatory sensitive in the milli-Hertz frequency band including the nature and evolution of massive black holes and their host galaxies, the demographics of stellar remnant compact objects in the Milky Way, and the behavior of gravity in the strong-field regime. I will also summarize the current status of efforts in the US and Europe to implement a space-based gravitational wave observatory. [Preview Abstract] |
