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...
