title: Statistical Analysis of Ultra Low Frequency Total Electron Content Disturbances: Relationship to Magnetospheric Waves

description: Disturbances in ionospheric Total Electron Content (dTEC) with timescales of ∼10s-1000s can be driven from above by processes in the magnetosphere and below by processes on the Earth’s surface and lower atmosphere. Past studies showed the potential of dTEC as a diagnostic of magnetospheric Ultra Low Frequency (ULF) wave activity and demonstrated that ULF dTEC can impact space weather by, for example, changing ionospheric conductance. However, most past work has focused on single event studies, lacked magnetospheric context, or used sampling rates too low to capture most ULF waves. Here, we perform a statistical study using Time History of Events and Macrsoscale Interactions during Substorms (THEMIS) satellite conjunctions with a ground-based magnetometer and Global Navigation Satellite System (GNSS) receiver at ∼65 degrees magnetic latitude. We find that magnetospheric ULF waves generate dTEC variations across the broad range of periods examined in this study (∼20-500s), and that ULF dTEC wave power is correlated with Kp, AE, solar wind speed, and satellite and ground magnetic field wave power. We further find that magnetospheric ULF waves generate dTEC amplitudes up to ∼ 5 TECU (∼ 30 − 40% background), with the largest amplitudes occurring during geomagnetically active conditions, at frequencies below 7 mHz, and at local times near midnight. We finally discuss the implications of our results for magnetosphere ionosphere coupling and remote sensing techniques related to ULF waves.

title: The High Energy X-ray Probe (HEX-P): Science Overview

description: To answer NASA's call for a sensitive X-ray observatory in the 2030s, we present the High Energy X-ray Probe (HEX-P) mission concept. HEX-P is designed to provide the required capabilities to explore current scientific questions and make new discoveries with a broadband X-ray observatory that simultaneously measures sources from 0.2 to 80 keV. HEX-P's main scientific goals include: (1) understand the growth of supermassive black holes and how they drive galaxy evolution; (2) explore the lower mass populations of white dwarfs, neutron stars, and stellar-mass black holes in the nearby universe; (3) explain the physics of the mysterious corona, the luminous plasma close to the central engine of accreting compact objects that dominates cosmic X-ray emission; and (4) find the sources of the highest energy particles in the Galaxy. These goals motivate a sensitive, broadband X-ray observatory with imaging, spectroscopic, and timing capabilities, ensuring a versatile platform to serve a broad General Observer (GO) and Guest Investigator (GI) community. In this paper we present an overview of these mission goals, which have been extensively discussed in a collection of more than a dozen papers presented in this Research Topic volume. The proposed investigations will address key questions in all three science themes highlighted by Astro2020, including their associated priority areas. HEX-P will extend the capabilities of the most sensitive low- and high-energy X-ray satellites currently in orbit, and will complement existing and planned high-energy, time-domain, and multi-messenger facilities in the next decade.

title: A Bubble in a Bubble [C II]-deficit caused by self-absorption in an ionized carbon filled bubble in RCW79

description: Recent spectroscopic observations of the [C II] 158  m fine structure line of ionized carbon (C+), using the Stratospheric Observatory for Infrared Astronomy (SOFIA), have revealed expanding [C II] shells in Galactic HII regions. Here, we report the discovery of abubble (source S144 in the GLIMPSE survey), associated with a compact HII region (cH IIR), excited by a single O7.5􀀀9.5V/III star, that is still mostly “filled” with C+. S144 is prominent in [C II] and 8  m emission without a central void, indicating a very early evolutionary state in which the stellar wind has not yet blown material away, as it is the case for more evolved HII regions. Using the SimLine non-LTE radiative transfer code, the [C II] emission can be modeled to originate in three regions. First, a central HII region with little C+ in the fully ionized phase, followed by two layers with a gas density around 2500 cm􀀀3 of partially photo-dissociated gas. The second layer is a slowly expanding [C II] shell with an expansion velocity of  2:6 km/s that corresponds approximately to a bright ring at 8  m. The outermost layer exhibits a temperature and velocity gradient that produces the observed self-absorption features in the optically thick [C II] line (    4). The self-absorption leads to an apparent deficit in [C II] emission and a low ratioof [C II] to total far-infrared (FIR) emission. We developed a procedure to approximate the missing [C II] flux by fitting a Gaussian line to the [C II] line wings, considering the optical depth and the hyper-fine structure emission of [13CII]. With the corrected [C II] intensities, we find a linear correlation between [C II] and FIR without a [C II]-deficit. This example demonstrates that at least some of the [C II]-deficit found in Galactic HII bubbles can be attributed to self-absorption, although a broader sample of these objects needs to be studied to fully constrain the range of conditions where [C II]-deficits may be explained by this process.

title: High Precision Measurement of the 3P0 - 3P1 Atomic Oxygen Fine Structure Splitting at 2.06 THz

description: Observation of the atomic oxygen fine structure line at 2.06 Terahertz from an orbiting limb sounder serves as a compelling platform for the characterization of neutral winds in the lower thermosphere and ionosphere (LTI, $\sim$110 - 250 km). The precision of wind measurements retrieved from this prospective instrument class are directly linked to the rest frequency of this targeted transition as determined from laboratory measurements. This effort details recent work at the Jet Propulsion Laboratory to deploy a custom designed transmitter and heterodyne receiver pair optimized for performance at 2.06 THz for use in obtaining high-precision rest frequencies for the oxygen atom $^3$P$_0$\,-\,$^3$P$_1$ atomic fine structure splitting. Oxygen atom ($^{16}$O) is generated by an inductively coupled plasma system with direct absorption measurements obtained by a combined frequency and plasma modulated experimental scheme. Results are discussed in the context of previous laboratory measurements and the impact on prospective neutral wind measurements in the LTI.

title: Sample return missions: Rosetta stones returned from the first small bodies in the solar system

description: It is now possible to bring back samples from planetary bodies of the solar system other than the moon. This research method enables a direct link between astronomical observations and meteorite analyses, which were previously disconnected. The Hayabusa, Hayabusa2, and OSIRIS REx sample return missions have provided detailed information on the composition of S- and C-type asteroids and the processes by which they were formed. This paper describes the results of these three asteroid sample return missions, and also introduces the next Martian moon sample return mission. Although sample returns are currently achieved only from near-Earth objects in the solar system, it is hoped that in the future it will be possible to collect samples from outer solar system objects and even from small objects flying from outside the solar system.

title: Remotely sensing drought stress in Q. douglasii is complicated by the unstable relationship between drought status and water content

description: Remote sensing is a powerful tool for ecosystem monitoring, yet has been limited by its ability to capture early warning metrics of tree drought stress. The foundational measurement of tree physiological water status, water potential, has not been well-linked to remotely sensed products that estimate the amount of water in tree canopies. To test remote sensing’s ability to capture changes in tree water status, we investigated the stability of relationships between water potential and area- and mass-based metrics of water content (measured in-situ and via airborne hyperspectral sensors) over diel, seasonal, and spatial variation. We assess the utility of ‘space for time’ and laboratory-based approaches for establishing relationships among in-situ and remotely sensed water status metrics. We found strong and consistent relationships within late-season temporal and spatial sources of variation, indicating that water content can be linked to water potential when leaf morphology is known (i.e. when water content is represented on a mass-basis). However, inconsistency across sources of variation did not support space-for-time approaches. Laboratory-based relationships only accurately reflected diel patterns, not those observed across the landscape or over time; as such, classic benchtop drydown methods do accurately describe leaf capacitance but are not good proxies for estimating larger-scale patterns of tree stress. Taken together, our findings highlight how covariation between water status and leaf morphology act as confounding physiological processes that can mask drought-response signals in area-based remote sensing products, and highlight the importance of fully characterizing drought stress signals across differing axes of variation.

title: Microstructured vortex and azimuthal cosine phase mask design for high-contrast imaging

description: At the extreme contrast levels required to image Earth-like planets around Sun-like stars, the polarization-dependence of the vector vortex coronagraph becomes a limiting factor, making wavefront control difficult to perform in both polarizations simultaneously. An alternative is to use a polarization-independent scalar vortex phase mask. However achromatizing scalar masks remains challenging. Here we propose to use metasurfaces to increase the bandwidth of scalar vortex phase masks. Our design shows an improvement of up to two orders of magnitude compared to a scalar vortex made of a helical shaped dielectric substrate. However, the characteristic phase discontinuities of scalar vortex phase masks introduce phase artifacts and remain challenging to manufacture accurately. The cosine phase mask is an alternative approach to implement a coronagraphic phase mask with a continuously varying azimuthal phase profile, but without the phase jump of the scalar vortex. In addition it requires smaller phase coverage. We therefore also investigate a metasurface implementation of the cosine mask. We present results obtained using Rigorous coupled-wave analysis and finite-difference time-domain simulations, and find that the phase jumps of a scalar vortex result in significant stellar leakage, which does not appear in the case of the cosine mask. We then present the coronagraphic performance and residual chromaticity of both designs and discuss their advantages and drawbacks. We conclude that metasurface scalar vortex and cosine phase masks are promising coronagraphic phase masks in the light of upcoming ground and space telescope missions.

title: Active tectonic processes at Venus coronae revealed by gravity and topography data

description: The enigmatic corona structures, widespread across Venus, are crucial for understanding the planet’s geodynamic state. Various scenarios exist for their formation, often involving plume-lithosphere interactions, and some coronae are suspected of hosting active, plate boundary-like processes such as subduction. In contrast to topography, the coarse resolution of available Venus gravity datasets has limited detailed analyses of gravity anomalies at coronae. Here, we leverage 3D geodynamic models to predict free-air and Bouguer gravity signals under different corona tectonic scenarios. Comparing model predictions to observations, we show that combining topography and gravity is more effective than analysing topography16alone. Among 75 coronae considered resolved by the Venus gravity dataset, gravity indicates buoyant mantle material beneath 52. Fitting observations to models reveals a spectrum of plume-lithosphere interactions and activity stages across these coronae, providing insights beyond previous analyses. We also demonstrate that the limited resolution of Magellan gravity can obscure positive gravity signatures at some coronae, making them appear inactive. We predict that the gravity dataset from the upcoming VERITAS mission will resolve 425 coronae, and identify sites of interest for upcoming missions. Along with improved knowledge of Venus’ lithospheric structure, forthcoming data will enable more robust analyses tailored to specific settings and revolutionize our understanding of Venus’ global geodynamics.
