Robert Wharton, 2021, "Scintillation timescale measurement of the highly active FRB 20201124A", https://doi.org/10.48577/jpl.YMKJ2N, Monthly Notices of the Royal Astronomical Society, JPL Open Repository
Scintillation of compact radio sources is caused by the interference between images caused by multipath propagation, and can be used to probe the intervening scattering plasma, and the velocities of the emitting source and scattering screen. In FRB20201124A, a repeating FRB which... |

Margaret Sipple-Srinivasan, 2021, "Success Stories of Satellite Altimeter Applications", https://doi.org/10.48577/jpl.UFYWVS, Bulletin of American Meteorological Society, JPL Open Repository
For nearly three decades, satellite nadir altimeters have provided essential information to understand, primarily ocean, and also, inland water dynamics. A variety of parameters can be inferred via altimeter measurements, including sea surface height, sea surface wind speeds, sig... |

Erik Ivins, 2021, "Notes on a Compressible Extended Burgers Model of Rheology", https://doi.org/10.48577/jpl.S5HKZQ, Geophysical Journal International, JPL Open Repository
Constitutive theory for viscoelasticity has broad application to solid mantle or ice deformations driven by tides, surface mass variations, and post-seismic flow. Geophysical models using higher order viscoelasticity can better accommodate geodetic observations than lower-order th... |

Brendan Byrne, 2021, "The carbon cycle of southeast Australia during 2 2019–2020: Drought, fires and subsequent recovery", https://doi.org/10.48577/jpl.AP7D51, AGU Advances, JPL Open Repository
2019 was the hottest and driest year on record for southeast Australia leading to bushfires of unprecedented extent between November 2019 and January 2020. In this study, we utilize space-based measurements of trace gases (TROPOspheric Monitoring Instrument XCO, Orbiting Carbon O... |

Mousavi, Mohammad, 2021, "Evaluation of Surface Melt on the Greenland Ice Sheet using SMAP L-Band Microwave Radiometry", https://doi.org/10.48577/jpl.IZAVQG, Journal of Selected Topics in Applied Earth Observations and Remote Sensing, JPL Open Repository
Monitoring melt extent and timing on the Greenland ice sheet is important for tracking the ice sheet’s mass and energy balance as well as the global and Arctic climate variability and change. In this study, we use L-band (1.4 GHz) brightness temperature observations collected by... |

Cochrane, Corey J, 2021, "In Search of Subsurface Oceans within the Uranian Moons", https://doi.org/10.48577/jpl.8WY24L, Journal of Geophysical Research: Planets, JPL Open Repository
The Galileo mission to Jupiter discovered magnetic signatures associated with hidden sub-surface oceans at the moons Europa and Callisto using the phenomenon of magnetic induction. These induced magnetic fields originate from electrically conductive layers within these moons and... |

Connor, Thomas P, 2021, "Discovery of a Possible Splashback Feature in the Intracluster Light of MACS J1149.5+2223", https://doi.org/10.48577/jpl.6VI6LN, Monthly Notices of the Royal Astronomical Society, JPL Open Repository
We present an analysis of the intracluster light in the Frontier Field Cluster MACSJ1149.5+2223 (z=0.544), which combines new and archival Hubble WFC3/IR imagingto provide continuous radial coverage out to 2.8 Mpc from the brightest cluster galaxy. Employingcareful treatment of p... |

Apurva Oza, 2021, "Volatile Transport Modeling on Triton with New Observational Constraints", https://doi.org/10.48577/jpl.4WWMXC, Icarus, JPL Open Repository
Neptune’s moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4and CO, and represents a benchmark case for the study of surface-atmosphere interactions onvolatile-rich Kuiper Belt objects. The observations of Pluto by New Horizons acquired during t... |

Connor, Thomas P, 2021, "X-Ray Evidence Against the Hypothesis that the Hyper-Luminous z = 6:3 Quasar J0100+2802 is Lensed", https://doi.org/10.48577/jpl.DDQRHQ, The Astrophysical Journal Letters, JPL Open Repository
The z = 6:327 quasar SDSS J010013.02+280225.8 (hereafter J0100+2802) is believed to be powered by ablack hole more massive than 1010 M , making it the most massive black hole known in the first billion yearsof the Universe. However, recent high-resolution ALMA imaging shows four... |

Apurva Oza, 2021, "Evolution of Mercury's Earliest Exosphere", https://doi.org/10.48577/jpl.8RGSJC, The Planetary Science Journal, JPL Open Repository
MESSENGER observations suggest a magma ocean formed on proto-Mercury, during which evaporation of metals and outgassing of C- and H-bearing volatiles produced an early atmosphere. Atmosphericescape subsequently occurred by plasma heating, photoevaporation, Jeans escape, and photo... |
