Stone Skipping Black Holes in Ultralight Dark Matter Solitons
Alan Zhang, Yourong Wang, J. Luna Zagorac +1
The orbit of a black hole moving within an ultralight dark matter (ULDM) soliton is naively expected to decay due to dynamical friction. However, in isolated near-circular soliton-…
The three phases of self-gravitating scalar field ground states
Anthony E. Mirasola, Nathan Musoke, Mark C. Neyrinck +2
It is generally assumed that scalar field dark matter halos would contain solitonic cores -- spherically symmetric ground state configurations -- at their centers. This is especial…
Astronomy as a Field: A Guide for Aspiring Astrophysicists
Ava Polzin, Yasmeen Asali, Sanah Bhimani +25
This book was created as part of the SIRIUS B VERGE program to orient students to astrophysics as a broad field. The 2023-2024 VERGE program and the printing of this book is funded…
Scalar Field Dark Matter: Impact of Supernovae-driven blowouts on the soliton structure of low mass dark matter halos
Victor H. Robles, J. L. Zagorac, N. Padmanabhan
We present the first study on the gravitational impact of supernova feedback in an isolated soliton and a spherically symmetric dwarf SFDM halo of virial mass $1\times 10^{10}\math…
Multifield Ultralight Dark Matter
Mateja Gosenca, Andrew Eberhardt, Yourong Wang +4
Ultralight dark matter (ULDM) is usually taken to be a single scalar field. Here we explore the possibility that ULDM consists of light scalar fields with only gravitational in…
Soliton Formation and the Core-Halo Mass Relation: An Eigenstate Perspective
J. Luna Zagorac, Emily Kendall, Nikhil Padmanabhan +1
UltraLight Dark Matter (ULDM) is an axion-like dark matter candidate with an extremely small particle mass. ULDM halos consist of a spherically symmetric solitonic core and an NFW-…
Schrödinger-Poisson Solitons: Perturbation Theory
J. Luna Zagorac, Isabel Sands, Nikhil Padmanabhan +1
Self-gravitating quantum matter may exist in a wide range of cosmological and astrophysical settings from the very early universe through to present-day boson stars. Such quantum m…
GUT-Scale Primordial Black Holes: Mergers and Gravitational Waves
J. Luna Zagorac, Richard Easther, Nikhil Padmanabhan
Tight constraints on the abundance of primordial black holes can be deduced across a vast range of masses, with the exception of those light enough to fully evaporate before nucleo…
