The g factors of 11/2− isomers in semimagic 109Sn and 111Sn (isomeric lifetimes τ=2.9(3) ns and τ=14.4(7) ns, respectively) were measured by an extension of the Time Differential Perturbed Angular Distribution technique, which uses LaBr3 detector

CEERS Key Paper. VIII. Emission-line Ratios from NIRSpec and NIRCam Wide-Field Slitless Spectroscopy at z > 2

Publikováno v: The Astrophysical Journal, Vol 962, Iss 2, p 195 (2024)

We use James Webb Space Telescope Near-Infrared Camera Wide Field Slitless Spectroscopy (NIRCam WFSS) and the Near-Infrared spectrograph (NIRSpec) in the Cosmic Evolution Early Release survey to measure rest-frame optical emission-line ratios of 155

Back From the Brink : Lessons From the Canadian Asset-Backed Commercial Paper Crisis

Autor: Paul Halpern, Caroline Cakebread, Christopher C. Nicholls, Poonam Puri

As global markets toppled during the 2008 financial crisis, the Canadian market for non-bank asset-backed commercial paper (ABCP) seemed on the verge of collapsing. Fueled by a top rating from DBRS, ABCP had found its way into the portfolios of some

Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-frame UV photons, these sources are e

Spatially Resolved Temperature and Density Structures of Nearby H ii Regions

Autor: Yifei Jin, Ralph Sutherland, Lisa J. Kewley, David C. Nicholls

Publikováno v: The Astrophysical Journal, Vol 958, Iss 2, p 179 (2023)

Photoionization models frequently assume constant temperature or density within H ii regions. We investigate this assumption by measuring the detailed temperature and density structures of four H ii regions in the Large Magellanic Cloud and the Small
