Dust Battery: A Novel Mechanism for Seed Magnetic Field Generation in the Early Universe
Nadine H. Soliman, Philip F. Hopkins, Jonathan Squire
We propose a novel dust battery mechanism for generating seed magnetic fields in the early universe, in which charged dust grains are radiatively accelerated, inducing strong elect…
Are Stars Really Ingesting their Planets? Examining an Alternative Explanation
Nadine H. Soliman, Philip F. Hopkins
Numerous stars exhibit surprisingly large variations in their refractory element abundances, often interpreted as signatures of planetary ingestion events. In this study, we propos…
Thermodynamics of Giant Molecular Clouds: The Effects of Dust Grain Size
Nadine H. Soliman, Philip F. Hopkins, Michael Y. Grudić
The dust grain size distribution (GSD) likely varies significantly across star-forming environments in the Universe, but its impact on star formation remains unclear. This ambiguit…
Dust-Evacuated Zones Near Massive Stars: Consequences of Dust Dynamics on Star-forming Regions
Nadine H. Soliman, Philip F. Hopkins, Michael Y. Grudić
Stars form within dense cores composed of both gas and dust within molecular clouds. However, despite the crucial role that dust plays in the star formation process, its dynamics i…
Microphysical Regulation of Non-Ideal MHD in Weakly-Ionized Systems: Does the Hall Effect Matter?
Philip F. Hopkins, Jonathan Squire, Raphael Skalidis +1
The magnetohydrodynamics (MHD) equations plus 'non-ideal' (Ohmic, Hall, ambipolar) resistivities are widely used to model weakly-ionized astrophysical systems. We show that if grad…
Co-Evolution vs. Co-existence: The Effect of Accretion Modelling on the Evolution of Black Holes and Host Galaxies
Nadine H. Soliman, Andrea V. Macciò, Marvin Blank
We append two additional black hole (BH) accretion models, namely viscous disc and gravitational torque-driven accretion, into the Numerical Investigation of a Hundred Astrophysica…
Dust Dynamics in AGN Winds: A New Mechanism For Multiwavelength AGN Variability
Nadine H. Soliman, Philip F. Hopkins
Partial dust obscuration in active galactic nuclei (AGN) has been proposed as a potential explanation for some cases of AGN variability. The dust-gas mixture present in AGN tori is…
NIHAO XXVII: Crossing the green valley
Marvin Blank, Andrea V. Macciò, Xi Kang +2
The transition of high-mass galaxies from being blue and star forming to being red and dead is a crucial step in galaxy evolution, yet not fully understood. In this work, we use th…
Dust in the Wind with Resonant Drag Instabilities: I. The Dynamics of Dust-Driven Outflows in GMCs and HII Regions
Philip F. Hopkins, Anna L. Rosen, Jonathan Squire +4
Radiation-dust driven outflows, where radiation pressure on dust grains accelerates gas, occur in many astrophysical environments. Almost all previous numerical studies of these sy…
NIHAO XXVI: Nature versus nurture, the Star Formation Main Sequence and the origin of its scatter
Marvin Blank, Liam E. Meier, Andrea V. Macciò +4
We investigate how the NIHAO galaxies match the observed star formation main sequence (SFMS) and what the origin of its scatter is. The NIHAO galaxies reproduce the SFMS and genera…
