Radial dust distributions and obscuring geometry in AGN from JWST/MIRI spectroscopy
Ruiyu Pan, Arkaprabha Sarangi
The spatial distribution of obscuring dust in active galactic nuclei (AGN) is critical for distinguishing between static torus models and dynamical disk-wind scenarios. To constrai…
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…
Dust formation in AGN winds
Arkaprabha Sarangi, Eli Dwek, Demos Kazanas
Infrared observations of active galactic nucleus (AGN) reveal emission from the putative dusty circumnuclear 'torus' invoked by AGN unification, that is heated up by radiation from…
Astro2020 Science White Paper: Are Supernovae the Dust Producer in the Early Universe?
Jeonghee Rho, Danny Milisavljevic, Arkaprabha Sarangi +23
Whether supernovae are a significant source of dust has been a long-standing debate. The large quantities of dust observed in high-redshift galaxies raise a fundamental question as…
