Aaron Bello Arufe, 2024, "Constraints on atmospheric water abundance and cloud deck pressure in the warm Neptune GJ 3470 b via CARMENES transmission spectroscopy", https://doi.org/10.48577/jpl.OPBETF, MNRAS, JPL Open Repository
Observations of cooler atmospheres of super-Earths and Neptune sized objects often show ŕat transmission spectra. The most likely cause of this trend is the presence of aerosols (i.e. clouds and hazes) in the atmospheres of such objects. Highresolution spectroscopy provides an op... |

Slava Turyshev, 2024, "Search for gravitationally lensed interstellar transmissions", https://doi.org/10.48577/jpl.XOYFLK, Physical Review D, JPL Open Repository
We consider interstellar light transmission aided by a gravitational lens. We find that optimal reception efficiency occurs in lensing geometries where the transmitter, lens, and receiver are nearly aligned. We explore various signal detection strategies, employing both existing... |

Brandon Hensley, 2024, "The BLAST Observatory: Sensitivity Study for Far-IR Polarimeters", https://doi.org/10.48577/jpl.YX4FXH, Publications of the Astronomical Society of the Pacific, JPL Open Repository
Sensitive wide-field observations of polarized thermal emission from interstellar dust grains will allow astronomers to address key outstanding questions about the life cycle of matter and energy driving the formation of stars and the evolution of galaxies. Stratospheric balloon-... |

James Wallace, 2024, "Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor", https://doi.org/10.48577/jpl.C5BJFP, The Astrophysical Journal Letters, JPL Open Repository
We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing errors are a primary contributor to contrast limits on Keck and will be necessary to correct for the next... |

Catherine Clark, 2024, "VaTEST III: Validation of 8 Potential Super-Earths from TESS Data", https://doi.org/10.48577/jpl.HN8VQZ, Proceedings of the International Astronomical Union, JPL Open Repository
NASA’s all-sky survey mission, the Transiting Exoplanet Survey Satellite (TESS), is specifically engineered to detect exoplanets that transit bright stars. Thus far, TESS has successfully identified approximately 400 transiting exoplanets, in addition to roughly 6000 candidate ex... |

Bonnie Buratti, 2024, "Pre-impact albedo map and photometric properties of the (65803) Didymos asteroid binary system from DART and ground-based data", https://doi.org/10.48577/jpl.KVMNJB, Planetary Science Journal, JPL Open Repository
This study provides a pre-impact map of the albedo of the Double Asteroid Redirection Test (DART) target Dimorphos corrected for all the effects of viewing geometry, as well as an estimate of photometric roughness for the hemisphere imaged by DART. Other photometric properties ar... |

Catherine Elder, 2024, "Rocks with extremely low thermal inertia at the OSIRIS-REx sample site on asteroid Bennu", https://doi.org/10.48577/jpl.DOLOBK, Planetary Science Journal, JPL Open Repository
The OSIRIS-REx mission recently returned a sample of rocks and dust collected from asteroid Bennu. We analyzed the highest-resolution thermal data obtained by the OSIRIS-REx Thermal Emission Spectrometer (OTES) to gain insight into the thermal and physical properties of the sampl... |
