Marzia Parisi, 2023, "Gravity Investigation to Characterize Enceladus’ Ocean and Interior", https://doi.org/10.48577/jpl.TTFP7B, The Planetary Science Journal, JPL Open Repository
A key objective for the future exploration of the icy moon Enceladus is the characterization of the habitable conditions in its internal ocean. Radio science instrumentation onboard a spacecraft in a low-altitude orbit about Enceladus would enable gravity measurements that are fu... |

Daniel Cunnane, 2023, "High-Efficiency Ka-Band Frequency Multiplier Based on the Non-Linear Kinetic Inductance in a Superconducting Microstrip", https://doi.org/10.48577/jpl.LCR39X, Physical Review Applied, JPL Open Repository
LO sources have become a major technological deficit approaching the THz frequencies. Forapplications where a narrow linewidth is necessary, such as coherent remote sensing, the best solutionto signal generation is frequency multiplication, where phase locking can be easily achie... |

Laurent Pou, 2023, "Tidal dissipation of binaries in asteroid pairs", https://doi.org/10.48577/jpl.O5GDG6, Icarus, JPL Open Repository
Tidal dissipation in a celestial body can be used to probe their internal structure. Tides govern the orbital evolution of binary systems and therefore constraints on the interior of binary system members can be derived by knowing the age and tidal state of the binary system. For... |

Daniel Stern, 2023, "The High Energy X-ray Probe (HEX-P): Probing the physics of the X-ray corona in active galactic nuclei", https://doi.org/10.48577/jpl.UVNCMJ, Frontiers of Astronomy and Space Sciences, JPL Open Repository
The hard, non-thermal X-ray emission in active galactic nuclei (AGN) and black hole X-ray binaries (BHXRBs) is traditionally thought to be produced by a hot cloud of electrons referred to as the corona, which resides in close vicinity to the central black hole. This emission is c... |

Longtao Wu, 2023, "Uncertainty of Atmospheric Winds in the Reanalysis Datasets", https://doi.org/10.48577/jpl.ICGIQJ, Journal of Applied Meteorology and Climatology, JPL Open Repository
Atmospheric winds are essential to transport heat, moisture, momentum, and chemical species and enable the interactions between components of Earth’s climate system. However, direct observations of three-dimensional distributions of atmospheric winds are scarce. Existing studies... |

Ashish Goel, 2023, "Modeling Science Return from the Lunar Crater Radio Telescope on the Far Side of the Moon", https://doi.org/10.48577/jpl.LDQUPK, Philosophical Transactions of the Royal Society A, JPL Open Repository
The era following the separation of CMB photons from matter, until the emergence of the first stars and galaxies, is known as the Cosmic Dark Ages. The study of the electromagnetic radiation emitted by neutral hydrogen at the 21~cm rest wavelength is the only way to explore this... |

Luis Millan Valle, 2023, "Water Vapor Measurements inside clouds and storms using a Differential Absorption Radar", https://doi.org/10.48577/jpl.MXIOYZ, Atmospheric Measurement Techniques, JPL Open Repository
NASA’s Vapor In-cloud Profiling Radar (VIPR) is a tunable G-band radar designed for in-cloud and precipitation humidity remote sensing. VIPR estimates humidity using the differential absorption radar (DAR) technique. This technique exploits the difference between atmospheric atte... |

Hartmut Aumann, 2023, "Northward shift and narrowing of the ITCZ in 20 years of AIRS data", https://doi.org/10.48577/jpl.BIQCYX, Journal of Geophysical Research: Atmosphere, JPL Open Repository
A time series analysis of Atmospheric InfraRed Sounder (AIRS) data between 2002 and 2022 show that both mean northern and southern boundaries of the Inter Tropical Convergence Zone (ITCZ) have shifted north for land and ocean. Such a shift is plausible, but has not predicted and... |

Michael Ressler, 2023, "JOYS+: mid-infrared detection of gas-phase SO2 emission in a low-mass protostar; The case of NGC 1333 IRAS2A: hot core or accretion shock?", https://doi.org/10.48577/jpl.RGDBPS, Astronomy & Astrophysics, JPL Open Repository
Context. The Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) has sharpened our infrared eyes toward the star formation process. Due to its unprecedented spatial and spectral resolution and sensitivity in the mid-infrared, JWST/MIRI can see through highly e... |

Robert Anderson, 2023, "Early Noachian Terrains: Vestiges of the Early Evolution of Mars", https://doi.org/10.48577/jpl.YX7RDK, Icarus, JPL Open Repository
NASA's main scientific reason for exploring Mars is to determine the early evolution and the possibility of life on the red planet. Scientists have adopted an approach for identifying habitable environments on Mars that could be conducive to the early development and preservation... |
