Curriculum Vitae:

Jacqueline McCleary

I have always been passionate about astrophysics. My research experiences began as an intern at NASA’s Goddard Space Flight Center and the Harvard-Smithsonian Center for Astrophysics characterizing the outflows of young stellar objects. Upon graduating from UChicago, I entered New Mexico State University, where in collaboration with the N-Body Shop group at University of Washington I analyzed hydrodynamic N-body simulations of galaxy evolution to investigate efficiency of feedback mechanisms and compare kinematic and photometric decompositions of disk galaxies.

My more recent expertise from my PhD at Brown (2017) is in weak gravitational lensing analyses of extremely low redshift (z<0.10) clusters of galaxies. In and of themselves, the maps produced by such WL analysis can help to characterize the dark matter that makes up 80% of gravitationally interacting matter. An ensemble of WL cluster maps at different redshifts, used to generate a cluster mass function, could also be a probe of dark energy.

I have also designed a successful astrophysics survey course, “From the Solar System to the Universe,” which I have taught three times as part of the Summer@Brown program.

In 2017, I joined the Origins of the Universe group at JPL as a post-doc. I am designing a data analysis pipeline, optimized for cluster weak lensing, for the upcoming SuperBIT mission. This exciting project features a balloon-borne imaging telescope that will deliver space-like imaging at a fraction of the cost, and should launch in 2019. I am also coordinating the target list for SuperBIT, and helping the team understand what cosmology we can do with the instrument.

SuperBIT Icon SuperBIT
SuperBIT is a mid-latitude (launch from Wanaka, NZ) ultra-long duration balloon (ULDB), which will provide 100 days of near space-quality imaging of selected galaxy clusters to study properties of dark energy and dark matter.
