Chandra Observations of the Radio Galaxy 3C 445 and the Hotspot X-ray Emission Mechanism [PDF]

open access: yes, 2009
We present new {\it Chandra} observations of the radio galaxy 3C 445, centered on its southern radio hotspot. Our observations detect X-ray emission displaced upstream and to the west of the radio-optical hotspot.

Identification of Erosional Terraces on Seamounts: Implications for Interisland Connectivity and Subsidence in the Galápagos Archipelago

open access: yesFrontiers in Earth Science, 2018
Shallow seamounts at ocean island hotspots and in other settings may record emergence histories in the form of submarine erosional terraces. Exposure histories are valuable for constraining paleo-elevations and sea levels in the absence of more ...

Sub-Arcsecond Imaging of 3C123:108-GHz Continuum Observations of the Radio Hotspots [PDF]

open access: yes, 1999
We present the results of sub-arcsecond 108 GHz continuum interferometric observations toward the radio luminous galaxy 3C123. Using multi-array observations, we utilize the high u,v dynamic range of the BIMA millimeter array to sample fully spatial ...

Hemispheric Geochemical Dichotomy of the Mantle Is a Legacy of Austral Supercontinent Assembly and Onset of Deep Continental Crust Subduction

open access: yesAGU Advances, 2022
Oceanic hotspots with extreme enriched mantle radiogenic isotopic signatures—including low 143Nd/144Nd indicative of subducted continental crust—are linked to plume conduits sampling the southern hemispheric mantle.

Non-occupational exposure to asbestos is the main cause of malignant mesothelioma in women in North Jutland, Denmark

open access: yesScandinavian Journal of Work, Environment & Health, 2019
OBJECTIVES: Diffuse malignant mesothelioma (MM) is mainly caused by asbestos inhalation. The malignancy is rare among women and studies of the prevalence and causative role of non-occupational asbestos exposure among women with MM are scarce.
