title: FIRED Ethiopia November 2000 - December 2024

description: This is event-level polygons for the fire event delineation (FIRED) product for ETHIOPIA from November 2000  to December 2024. It is derived from the MODIS MCD64A1 burned area product (see https://lpdaac.usgs.gov/products/mcd64a1v061/ for more details). The MCD64A1 is a monthly raster grid of estimated burned dates. Firedpy (https://github.com/earthlab/firedpy) is an algorithm that converts these rasters into events by stacking the entire time series into a spatial-temporal data cube, then uses an algorithm to assign event identification numbers to pixels that fit into the same 3-dimensional spatial temporal window. This particular dataset was created using a spatial parameter of 1 pixels and 5 days. Daily polygons are included and the event identification numbers are the same for both files, but the event-level product has only single polygons for each entire event, while the daily product has separate polygons for each date per event.

title: The Atacama Cosmology Telescope: DR6 Power Spectrum Foreground Model and Validation

description: We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6), expanding on Louis et al. (2025). We detail a number of tests to validate the capability of the DR6 parametric foreground model to describe both current observations and complex sky simulations, and show that cosmological parameter constraints are robust against model extensions and variations. We demonstrate consistency of the model with pre-DR6 ACT data and observations from Planck and the South Pole Telescope. We evaluate the implications of several model variations, including using different foreground templates and extending the model with new components and/or free parameters. In all scenarios, the ΛCDM and ΛCDM+Neff cosmological parameters from the DR6 data shift by less than 0.5σ relative to the baseline constraints. Foreground parameters may shift more; we estimate their systematic uncertainties associated with modeling choices. [AVE: From our constraint on the kinematic Sunyaev-Zel’dovich power, we obtain a conservative limit on the duration of reionization of Δzrei &lt; 4.4, assuming a reionization midpoint consistent with optical depth measurements and assuming a minimal low-redshift contribution, with varying assumptions for this component leading to tighter limits.] Finally, we construct realistic non-Gaussian, correlated microwave sky simulations containing all non-negligible Galactic and extragalactic foreground fields. The simulations are built independently of the DR6 parametric foreground model. [ks: We process these simulations through the DR6 power spectrum and likelihood pipeline and show that we recover the input cosmological parameters of the underlying cosmic microwave background field, demonstrating such parameter recovery from realistically correlated, non-Gaussian simulations for the first time in such a CMB analysis.] These tests validate the robustness of the ACT DR6 foreground model and cosmological parameter constraints.

title: ALMAGAL VI. The spatial distribution of dense cores during the evolution of cluster-forming massive clumps

description: Context. High-mass stars and star clusters form from the fragmentation of massive dense clumps driven by gravity, turbulence and magnetic field. The extent to which each of these agents impacts the fragmentation depending on the clump mass, density and evolutionary stage is still largely unknown. Aims. The ALMAGAL project, with∼1000 clumps observed at∼1000 au resolution, allows a statistically significant characterization of the fragmentation process over a large range of clump physical parameters and evolutionary stages. Our goal is to characterize where and how the dense cores revealed by ALMA are distributed in massive potentially cluster-forming clumps to trace how fragmentation is initially set and how it proceeds before gas dispersal due to stellar feedback. Methods. We characterized the spatial distribution of dense cores in the 514 ALMAGAL clumps that host at least 4 cores, using a set of quantitative descriptors that we evaluated against the clump L/M ratio, which we adopted as an indicator of the evolution of the system. We measured the separations between cores with the minimum spanning tree method (MST), which we compared with the predictions of gravitational fragmentation from Jeans theory. We investigated whether cores have specific arrangements using the Q-parameter or variations due to their masses with the mass segregation ratio, ΛMS R. Results. The ALMAGAL cores are distributed throughout the entire area of the clump, usually arranged in elliptical groups with an axis ratio e∼2.2, although high values with e ≥5 are also observed. We found a single characteristic core separation per clump in∼76% of the cases, suggesting that multiple fragmentation lengths may be frequently present. Typical cores separations are compatible with clump-averaged thermal Jeans length, λth J . However, we found an additional population of cores, typical of low-fragmented and young clumps, which are on average more widely separated with l ≈3 ×λth J . By stacking the distributions of the core separations in clumps of similar evolutionary stage, we also found that separation decreases on average from l∼22000 au in younger systems to l∼7000 au in more evolved ones. The ALMAGAL cores are typically distributed in fractal-type subclusters, while centrally concentrated patterns appear only at later stages, but we do not observe a progressive transition between these configurations with evolution. Finally, we also found 101 ALMAGAL systems with a signature of mass segregation, with an occurrence that increases with evolution.

title: Information--Thermodynamic Bounds on Planetary Biosphere Productivity and Their Observational Tests

description: The productivity of a planetary biosphere is limited by how its free-energy budget is partitioned between maintaining a habitable environment, driving metabolism, and processing heritable information. We derive an upper bound on net primary productivity (NPP) from non-equilibrium thermodynamics and information theory, given a planet's usable free-energy flux and a few coarse-grained biological parameters. The bound subtracts an irreducible power cost of heritable information processing---set by global template-copying rates, copying fidelity, alphabet size, and proofreading work---from the planetary power budget before converting the remainder into biomass. This yields an ``information--productivity trade-off'': at fixed planetary power, higher copying rates, lower error rates, larger alphabets, or more intensive proofreading all lower the ceiling on biomass production. Using conservative parameter choices, we show that Earth lies well below this ceiling, whereas low-flux environments such as M-dwarf habitable zones and subsurface ocean worlds can be driven into an information-limited regime where only modest combinations of productivity and heritable complexity are attainable. We outline how future exoplanet observations of stellar irradiation, climate, atmospheric disequilibria, and temporal variability could be used to place physics-based upper limits on NPP and compare them with independent productivity estimates.

title: Time of Flight from Optical Communications Signals on the Optical to Orion Demonstration

description: The Orion Artemis II Optical Communications System (informally, Optical to Orion (O2O)) demonstration will showcase standards-compliant High Photon Efficiency (HPE) optical communications for the first time on a crewed cislunar mission with Artemis II. In addition to the high data rate capability afforded by the optical signal, O2O uses the optical signal to enable a high-precision, synchronous, two-way telemetry ranging system for time of flight (ToF) measurement. In this paper we will describe the ToF system used for O2O, from the system architecture and algorithms, to simulations of predicted performance, and finally laboratory experiments of the system over several kilometers of fiber. We additionally describe a calibration technique in the ground terminal that eliminates the need for the measurement of multiple independent paths and test equipment delays. We show that the system enables high precision (&lt; 100 ps) high accuracy (&lt; 1 ns) ranging estimation over a wide variety of conditions.

title: Uranus' Long-term Thermospheric Cooling is unlikely to be primarily driven by the Solar Wind

description: Over the last 40 years, Uranus’ thermospheric temperature has decreased by ~8K/yr. Here we show that this is unlikely to be driven by the weakening solar wind. We have estimated that the expected energy change from the solar wind would not be sufficient to change the thermospheric temperature. We also show that the solar wind kinetic power has been increasing since 2008, while Uranus’s thermospheric temperature has continued to decline. Since 2008, a fitted trend shows a change in the solar wind kinetic power at Uranus of +28% while the thermospheric temperature changed by -29%. A comparison of the ascending phases of solar cycles 24 and 25 also show an increase in solar wind power of 15%, with a decrease in temperature of 18%. If the solar wind was a driver of thermospheric temperature at Uranus it would be expected that Uranus would have reversed its declining temperature also.

title: An algorithm to retrieve peroxyacetyl nitrate from AIRS

description: Herein, we describe a approach to retrieve free tropospheric columns of peroxyacyl nitrates (PANs) from radiances observed by the Atmospheric Infrared Sounder (AIRS). AIRS has provided daily global coverage since its launch in 2002, making it a valuable long term record. Although the instrument is very radiometrically stable, the radiance noise level is large enough to present a challenge when retrieving a weak absorber such as PAN. To address this, we focus on retrievals over land (to avoid interferences from low, warm clouds over ocean) and develop a decision tree quality filter trained to predict whether a PAN value retrieved from AIRS will be within 0.2 ppb or 50\% of what would be retrieved from the Cross-track Infrared Sounder (CrIS). We show that AIRS is capable of retrieving PAN plumes from significant wildfires that match those retrieved from CrIS and that PAN retrieved from AIRS has good correlation with CrIS given sufficient averaging. We conclude with recommendations for users to help ensure that these data are used appropriately.
