Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**
Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Dust grain dynamics due to nonuniform and nonstationary high-frequency radiations in cold magnetoplasmas [PDF]
Annales Geophysicae, 2006 A general nonlinear theory for low-frequency electromagnetic field generation due to high-frequency nonuniform and nonstationary electromagnetic radiations in cold, uniform, multicomponent, dusty magnetoplasmas is developed.

GalaxiesObservations provided by the Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) have revealed a surprising abundance of galaxies at the “cosmic dawn” epoch, z>7. Some of them are found even in a more distant universe at z ≃ 14–16. Most of

Cosmic rays, gas and dust in nearby anticentre clouds : I -- CO-to-H2 conversion factors and dust opacities [PDF]
, 2017 We aim to explore the capabilities of dust emission and rays for probing the properties of the interstellar medium in the nearby anti-centre region, using gamma-ray observations with the Fermi Large Area Telescope (LAT), and the thermal dust optical ...

Journal of Quaternary Science, EarlyView.Abstract The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...

Journal of Materials Research and Technology, 2020 Mesoscopic superconducting particles can be used as a model material for the cognition of the properties of a possible superconducting cosmic dust. In order to acquire the desired fraction between 1–10 µm, the method of the grain size separation based on

First Constraints on Dense Molecular Gas at z = 7.5149 from the Quasar Pōniuā‘ena
The Astrophysical Journal Letters, 2023 We report the detection of CO(6–5) and CO(7–6) and their underlying continua from the host galaxy of quasar J100758.264+211529.207 (Pōniuā‘ena) at z = 7.5149, obtained with the NOrthern Extended Millimeter Array.

Obscuration by Diffuse Cosmic Dust [PDF]
Publications of the Astronomical Society of Australia, 1998 AbstractIf the background universe is observed through a significant amount of diffusely distributed foreground dust, then studies at optical wavelengths may be severely biased. Previous studies investigating the effects of foreground dust on background sources assumed dust to be ‘compactly’ distributed, i.e.
