Briefing: From urban foresight to project bundles—the case of Huntsville, Alabama

Urban foresight and its project packages may follow linear temporality paths towards intended urban futures. Changes in conditions in one project package might affect the others. This briefing argues that project bundling can offer a more dynamic way to implement these visions. S...

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low...

Polarization Measurement of Gamma-Ray Bursts with Fermi-GBM: The Case of GRB 180720B

Abstract To achieve confident nonzero polarization measurements for gamma-ray bursts (GRBs) we need sensitive polarimeters and bright GRBs. Here we report on the polarimetric analysis of the bright GRB 180720B using the Fermi Gamma-ray Burst Monitor (GBM). We rely on the detectio...

Spheroidal Resampling Analysis of High-Redshift Gamma-Ray Burst Spatial Densities

Gamma-ray bursts (GRBs) are bright transient sources that can be observed at high redshift. They can therefore be used as tracers of the distant large-scale structure, although the GRB redshift sample is sparse and affected by strong selection effects. We analyze the three-dimens...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Assessing Population Vulnerability to Water Service Disruptions: A Targeted Index to Inform Infrastructure Planning and Management

Abstract Water distribution systems are critical to the stability and well-being of communities but remain highly vulnerable to disruptions from natural disasters and aging. These disruptions do not impact all populations equally, making it essential to incorporate differential v...

Observational Phase-Coherent Residual Modulation in Type Ia Supernova Hubble Diagrams

We analyze a reported nonlinear-phase modulation in Type Ia supernovaHubble-diagram residuals, emphasizing visualization, cross-compilation phasecoherence, look-elsewhere effects, waveform choice, endpoint artifacts, andpassband systematics. In a reconstructed 7687-entry diagnost...

Multi-scale evapotranspiration and evaporative stress as indicators of vegetation health and drought response – an application in central Missouri, USA

Satellite estimates of evapotranspiration (ET) based on thermal infrared retrievals of land-surface temperature enable monitoring of vegetation water use and health/stress at sub-field to global scales. The information content of these products varies with pixel size, reflecting...
