The LargE Area burst Polarimeter (LEAP): a NASA mission of opportunity for the ISS

21 June 2024 • 09:10 - 09:30 Japan Standard Time | Room G414/415, North - 4F

Abstract

The LargE Area burst Polarimeter (LEAP) is a proposed Compton scattering polarimeter that will, for the first time, measure the level of polarization for a significant number of GRBs with sufficient sensitivity to determine the magnetic field structure, composition, energy dissipation mechanism of GRB jets, and determine the prompt emission mechanism of GRBs. Once approved, LEAP will be deployed as an external payload on the International Space Station (ISS) where it will measure GRB polarization over the energy range from 50–1000 keV, perform GRB spectroscopy from 20 keV to 6 MeV, and self-sufficiently determine the source direction. LEAP is uniquely suited to fill a critical gap in our knowledge regarding GRBs, by exposing the underlying physics that governs astrophysical jets and the extreme environment surrounding newborn compact objects.

Dr. Gaskin is a Research Astrophysicist at NASA Marshall Space Flight Center where she leads the X-ray Astronomy Group. She is currently on part-time Detail to the NESC as the Deputy to the Technical Fellow for the Sensors and Instrumentation Technical Discipline Team and she is the Deputy Principal Investigator on the LargE Area burst Polarimeter (LEAP) Phase A Explorers Mission of Opportunity study. She has worked for NASA for over two decades (as a contractor or Civil Servant). Her professional career includes leading, managing and supporting large to small projects across X-ray and gamma-ray astrophysics, and planetary science. Dr. Gaskin’s background is on the development of instrumentation for high-energy astrophysics and planetary missions, and on large mission concept development.
