Mass of the Southern Black Hole in NGC 6240 from Laser Guide Star Adaptive Optics

, 2011
NGC 6240 is a pair of colliding disk galaxies, each with a black hole in its core. We have used laser guide star adaptive optics on the Keck II telescope to obtain high-resolution ($\sim 0.06$") near-infrared integral-field spectra of the region ...

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

Pest Management Science, Volume 82, Issue 4, Page 3613-3624, April 2026.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Print Conventions and Authority in Three English Recipe Manuscripts

Renaissance Studies, Volume 40, Issue 2, Page 231-253, April 2026.
Abstract This article considers the uses of stylistic and visual conventions drawn from print books in three seventeenth‐ and eighteenth‐century recipe manuscripts at the University of Pennsylvania. We begin by analysing the title page, dedicatory epistle, catchwords, and headers of MS Codex 627, which imitates an edition of Hugh Plat's Delights for ...

Stratospheric Aerosol Particle Size Explains Divergent Limb and Solar Occultation Measurements After the Hunga Eruption

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The 2022 Hunga eruption significantly perturbed the stratosphere by injecting substantial water vapor and SO2 ${\text{SO}}_{2}$, drastically changing the Aerosol Optical Depth (AOD) and particle size. Post‐eruption, satellite limb‐scattering retrievals of aerosol extinction from Ozone Mapping and Profiler Suite Limb Profiler (OMPS‐LP) and ...

Near-Infrared Spectroscopy of 2M0441+2301 AabBab: A Quadruple System Spanning the Stellar to Planetary Mass Regimes [PDF]

, 2015
We present Keck/NIRC2 and OSIRIS near-infrared imaging and spectroscopy of 2M0441+2301 AabBab, a young (1--3 Myr) hierarchical quadruple system comprising a low-mass star, two brown dwarfs, and a planetary-mass companion in Taurus.

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Stars and brown dwarfs in the sigma Orionis cluster. III. OSIRIS/GTC low-resolution spectroscopy of variable sources [PDF]

, 2012
Context. Although many studies have been performed so far, there are still dozens of low-mass stars and brown dwarfs in the young sigma Orionis open cluster without detailed spectroscopic characterisation. Aims.

Economic Burden of Rheumatoid Arthritis in Low‐ and Middle‐Income Countries: Systematic Review and Meta‐Analysis

Arthritis Care &Research, Volume 78, Issue 3, Page 325-336, March 2026.
Objective The aim of this systematic review was to synthesize the economic impact of rheumatoid arthritis (RA) on households, health systems, and society in low‐ and middle‐income countries (LMICs). Methods Electronic databases such as PubMed, Web of Science, and CINAHL were searched using keywords related to RA and cost of illness.
