Efficient Interstellar Grain Growth from High Sticking Coefficients on Amorphous Carbon Dust
Clarke J. Esmerian, Duncan Bossion, Francois Dulieu +8
Cosmic dust is the solid phase of the interstellar medium (ISM), classically assumed to be composed of carbonaceous and silicate grains with size distributions spanning …
Silicate cosmic dust grain collisions in the interstellar medium: A molecular dynamics study
C. J. Esmerian, S. R. Hashemi, W. M. C. Sameera +7
(abridged) We aim to predict the most important parameters for grain-grain collision outcomes in models of interstellar grain population evolution: the threshold velocities for sha…
Probing Infrared eXcess to Investigate Early-Universe Dust (PIXIEDust)
Tom J. L. C. Bakx, Hiddo S. B. Algera, Jean-Baptiste Jolly +25
Despite the implied presence of dust through reddened UV emission in high-redshift galaxies, no dust emission has been detected in the (sub)millimetre regime beyond . This…
A warm ultra-luminous infrared galaxy just 600 million years after the Big Bang
T. J. L. C. Bakx, Laura Sommovigo, Yoichi Tamura +24
We present an Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 continuum detection () of MACS0416_Y1 that confirms the suspected warm dust (91 K) of…
The Binding Energies of Atoms on Amorphous Silicate Dust: A Computational Study
Kristoffer Hansson, W. M. C. Sameera, Clarke J. Esmerian +6
Context. We investigate the binding energies of atoms to interstellar dust particles, which play a key role in their growth and evolution, as well as for the chemical reactions on…
Accurate sticking coefficient calculation for carbonaceous dust growth through accretion and desorption in astrophysical environments
Duncan Bossion, Arkaprabha Sarangi, Susanne Aalto +5
Context. Cosmic dust is ubiquitous in astrophysical environments, where it significantly influences the chemistry and the spectra. Dust grains are likely to grow through the accret…
