    • Characterizing line-of-sight variability of polarized dust emission with future cmb experiments 

      Bull, Philip; McBride, Lisa; Hensley, Brandon S (Oxford University Press, 2023)
      While Galactic dust emission is often accounted for in cosmic microwave background (CMB) analyses by fitting a two-parameter modified blackbody (MBB) model in each pixel, typically a number of such clouds are found along ...

    • Gama/H-Atlas: The dust opacity-stellar mass surface density relation for spiral galaxies 

      Grootes, M.W.; Tuffs, R.J.; Jarvis, Matt (IOP Science, 2013)
      We report the discovery of a well-defined correlation between B-band face-on central optical depth due to dust and the stellar mass surface density of nearby spiral galaxies. This relation was derived from a sample of ...

    • The origin of the dust extinction curve in milky way-like galaxies 

      Davé, Romeel; Vogelsberger, M.; Li, Q; Torrey, P.; Narayanan, D. (Oxford University Press, 2021)
      We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve. Our model considers the formation of active ...

    • An overview of the Dwarf Galaxy Survey 

      Remy-Ruyer, A.; Galametz, M.; Vaccari, Mattia; Madden, S.C. (The Astronomical Society of the Pacific, 2013)
      The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galax- ies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and ...

    • Planck 2018 results. XI. Polarized dust foregrounds 

      Ballardini, M.; Akram, Y.; Ashdown, M. (EDP Sciences, 2020)
      The study of polarized dust emission has become entwined with the analysis of the cosmic microwave background (CMB) polarization in the quest for the curl-like B-mode polarization from primordial gravitational waves and ...

    • Spectroscopic and voltammetric analysis of platinum group metals in road dust and roadside soil 

      van der Horst, Charlton; Silwana, Bongiwe; Iwuoha, Emmanuel; Somerset, Vernon (MDPI, 2018)
      The emission of toxic compounds by increasing anthropogenic activities affects human health and the environment. Heavy road traffic and mining activities are the major anthropogenic activities contributing to the presence ...
