title: Formation of Coronae 1 Topography and Fractures via Plume Buoyancy and Melting

description: Coronae are volcanic-tectonic features seemingly unique to the surface of Venus. As such they offer potential insights into differences in geodynamic processes on Venus and Earth. Largely due to limitations in processing power and computational complexity, models of corona formation generally ignore the effect of melt and magmatism despite the presence of volcanic features like domes and lava flows. Here we present a new model of corona formation integrating visco-plastic rheology with two-phase flow melt migration. Additionally, we model brittle failure of surface material, viscous flow of partially molten material at depth, and cracking of solid rock from fluid pressure to exist in one model. The model consists of a two-dimensional half space model of a round plume body ascending through an asthenosphere and interacting with a Venusian lithosphere and crust. The size and temperature of the plume body, lithosphere thickness, crustal thickness, and regional strain rate are all varied over 20 model runs. Most models show deflection of the plume as it rises due to the increased viscosity of the base of the lithosphere. As the plume spreads and rises against the base of the lithosphere, melting occurs. Melt rises and accumulates in the lithosphere which supports surface topography. Brittle failure occurs at the surface due to the induced stress of the migrating plume body and rising melt. Increased temperatures and sizes of initial plumes result in larger topographies occurring over smaller timescales. Decreased temperatures and sizes of initial plumes result in smaller topographies over larger timescales. Increased lithosphere thickness generates smaller topographies. Thinner crusts result in more viscous lithosphere and more strain accumulation, creating surface depressions seen in approximately half of real corona. Both thicker crusts and increased regional strain result in lower viscosities at the base of the lithosphere, preventing the deflection of the plume body, which instead rises through the lithosphere relatively unimpeded. The models generally result in an evolutionary sequence of topographies and fracture patterns which resemble actual corona, without requiring a collapsing dome to create outer rims, as is often invoked for corona formation via upwelling plumes. Corona rim topography is generally created within 105 and 106 year timescales, while multiple rims or central depressions are generally observed over 106 year timescales. Observed topography is actively supported by partially molten regions in the lithosphere, supporting the notion of an active squishy-lid Venus. These partially molten regions are not centrally located and may provide a source for observed lava flows away from corona centers.

title: Monolithic optical resonator for high spectral purity laser and low-noise photonic millimeter-wave synthesis

description: Optical resonators as indispensable tools in optical metrology usually benefit from an evacuated and highly isolated environment to achieve peak performance. Here, we demonstrate a monolithic Fabry-Perot (FP) resonator in ambient environment, characterized with $4.5$~cm$^3$ volume, $2\times10^5$ finesse. \hl{We achieve 18 Hz integrated laser linewidth and $7\times10^{-14}$ frequency stability measured at 0.2~s averaging time, the highest spectral purity and stability have ever been demonstrated in the content of monolithic reference resonators.} By locking two separate lasers to distinct modes of the same cavity, generation of 96~GHz microwave signals is achieved with phase noise -100~dBc$/$Hz at 10~kHz frequency offset, more than an order of magnitude lower than previously achieved with injection-locked lasers. The compact monolithic FP cavity is promising for applications in spectrally pure, high-frequency microwave photonic references as well as optical clocks and other metrological devices, and can replace more technically demanding evacuated FP cavities that have filled those roles to date.

title: Lunar Trailblazer Ground System Development

description: Lunar Trailblazer is a NASA SIMPLEx mission scheduled for launch in late 2024. The mission's goal is to continue the search for water in its various forms on the Moon and to explore how temperature fluctuations impact it. The Mission Operations System and Ground Data Systems (MOS/GDS) for Lunar Trailblazer are the responsibility of IPAC on the Caltech campus, with Mission Design and Navigation at JPL. Lunar Trailblazer is using the AMMOS Instrument Toolkit (AIT) and Open MCT software developed by NASA JPL and NASA Ames, respectively, for DSN connectivity, commanding, telemetry displays, and telemetry storage and trending. Lunar Trailblazer is a target-driven mission, and the science planning system for target selection and scheduling is a custom Postgres database for target tracking. This paper describes the ground systems for LTB and their development, with special attention paid to contributions by undergraduate interns.

title: Mass, density, and radius of asteroid (16) Psyche from high-precision astrometry

description: We characterize asteroid (16) Psyche using high-precision astrometry, including the recent Gaia Focused Data Release. The gravitational perturbations of Psyche on other asteroids can be observable in case of mutual encounters. Using a least squares approach, we estimate the mass of Psyche by fitting astrometric data of asteroids that come within 0.05 au of Psyche. Combining the resulting individual estimates, we find GM = 1.601 ± 0.017 km3 s −2 . This result is robust against variations in the orbit determination setup and specific dataset used. The volume and equivalent radius of Psyche are currently constrained by occultations and radar and optical imaging to (5.75 ± 0.19) × 106 km3 and 111+2 −0.5 km, respectively. Given the volume of Psyche, our mass estimate corresponds to a bulk density of 4172 ± 145 kg m−3 , which is compatible with an M-type taxonomic classification. Finally, the phase-dependent photocenter offset is visible in the residuals of Gaia astrometric observations of Psyche. This effect is consistent with the size of Psyche.

title: NuSTAR Observations of Candidate Subparsec Binary Supermassive Black Holes

description: We present analysis of NuSTAR X-ray observations of three AGN that were identified as candidate subparsec binary supermassive black hole (SMBH) systems in the Catalina Real-Time Transient Survey based on apparent periodicity in their optical light curves. Simulations predict that close-separation accreting SMBH binaries will have different X-ray spectra than single accreting SMBHs. We previously observed these AGN with Chandra and found no differences between their low energy X-ray properties and the larger AGN population. However some models predict differences to be more prominent at energies higher than probed by Chandra. We find that even at the higher energies probed by NuSTAR, the spectra of these AGN are indistinguishable from the larger AGN population. This could rule out models predicting large differences in the X-ray spectra in the NuSTAR bands. Alternatively, it might mean that these three AGN are not binary SMBHs.

title: Full Polarimetric GNSS-R Assessment of the Freeze and Thaw States of the Terrestrial Cryosphere

description: The shift between frozen and thawed conditions on theEarth's surface influences climate, hydrology, and ecology. Aprimary objective of the Soil Moisture Active Passive (SMAP)mission is to estimate the surface binary freeze/thaw (F/T) state forthe northern hemisphere above 45° N latitude with a classificationaccuracy of 80% at 3-km spatial resolution and 2-day intervals.The objective was to be accomplished by the SMAP L-band radarmeasurements. In July 2015 the radar transmitter suffered ananomaly that prevented it from nominal operation. The missionpartially met the goal exceeding the targeted 80% accuracy but at36 km resolution. After the radar anomaly, the SMAP missionswitched the radar receiver band pass filter frequency to GPS L2c,acting as a full-polarimetric Global Navigation Satellite System –Reflectometry (GNSS-R) receiver, known as SMAP-Reflectometer(SMAP-R). This work focusses on using SMAP-R signals toclassify the F/T state over the Northern latitudes, within thelimitations of the dataset. An algorithm based on the seasonalthreshold approach that was originally envisioned for the SMAPradar is applied to the SMAP-R data (i.e., bistatic radar). Then thealgorithm is evolved using a Random Forest algorithm to aidthreshold selection from the discriminator built in the seasonalthreshold approach. This algorithm is applied for years 2016 to2022 over the Northern Hemisphere terrestrial cryosphere andshows an F/T classification accuracy agreement better than 97%with respect to the classification of the official SMAP F/TRadiometry product, proving the potential of polarimetric GNSSRto derive F/T
