Wang, Xu; Shi, Fang; Wallace, J. Kent, 2016, "Zernike wavefront sensor (ZWFS) development for Low Order Wavefront Sensing (LOWFS)", https://hdl.handle.net/2014/46145, SPIE Astronomical Telescopes + Instrumentation 2016, Edinburgh, Scotland, June 26 - July 1, 2016, JPL Open Repository
ZWFS is known to be photon noise optimal for measuring low order aberrations. Recently, ZWFS was selected as the baseline LOWFS technology on WFIRST for its sensitivity, accuracy, and its ease of integration with the starlight rejection mask. In this paper, we present the develop... |

Yasuhiro Hasegawa, 2021, "Z CMa: A Likely Flyby Event Caught in Action", https://doi.org/10.48577/jpl.YPJ3DI, nature astronomy, JPL Open Repository
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations of star formation1–3,but few direct observations of ongoing encounters have been made. Here we repo... |

Akeson, R., 2001, "YSO studies with infrared interferometers", https://hdl.handle.net/2014/12654, ['Young Stars Near Earth', 'Mountain View, California, USA'], JPL Open Repository
The observational technique of long baseline infrared interferometry provides a unique opportunity for studying the small scale structure of young stellar objects, particularly circumstellar disks and multiplicity. The technique of infrared interferometry is briefly described and... |

Eisenhardt, P.; Simpson, C.; Armus, L.; Chokshi, A.; Dicksinson, M.; Djorgovski, S.; Elston, R.; Jannuzi, B.; McCarthy, P.; Pahre, M.; Soifer, B., 1999, "Young Stars and Non-Stella Emission in the Aligned Radio Galaxy 3C 256", https://hdl.handle.net/2014/18000, ['Astrophysical Journal', 'USA'], JPL Open Repository
We present ground-based images of the z=1.824 radio galaxy 3C 256 in the standard BVRIJHK filters and an interference filter centered at 8800 A, a Hubble Space Telescope image in a filter dominated by Ly alpha emission (F336W), and spectra covering rest-frame wavelengths from Ly... |
