U–Pb dating on calcite paleosol nodules: first absolute age constraints on the Miocene continental succession of the Paris Basin
Published 2025-04-01“…</p> <p>In this study, we analysed pedogenic calcite nodules within a continental Miocene succession in the southwestern Paris Basin (the important paleontological site at Mauvières quarry, France). Following multi-method petrographic characterisation of the samples, LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) U–Pb dating was employed to obtain formation ages on the pedogenic calcite nodules. …”

AGN STORM 2. II. Ultraviolet Observations of Mrk 817 with the Cosmic Origins Spectrograph on the Hubble Space Telescope
Published 2023-01-01“…We measure rest-frame delayed responses between the far-ultraviolet continuum at 1180 Å and Ly α λ 1215 Å ( ${10.4}_{-1.4}^{+1.6}$ days), N v λ 1240 Å ( ${15.5}_{-4.8}^{+1.0}$ days), Si iv + ]O iv λ 1397 Å ( ${8.2}_{-1.4}^{+1.4}$ days), C iv λ 1549 Å ( ${11.8}_{-2.8}^{+3.0}$ days), and He ii λ 1640 Å ( ${9.0}_{-1.9}^{+4.5}$ days) using segments of the emission-line profile that are unaffected by absorption and blending, which results in sampling different velocity ranges for each line. However, we find that the emission-line responses to continuum variations are more complex than a simple smoothed, shifted, and scaled version of the continuum light curve. …”
