Born in the Dark: The Catastrophic Collapse of Fuzzy Dark Matter Solitons as the Origin of Little Red Dots
Tak-Pong Woo
JWST surveys have uncovered a population of compact, red sources ("Little Red Dots," LRDs) at that exhibit broad Balmer emission yet remain X-ray faint, implying heavy ob…
Propagating Instability for Wave Dark Matter
Ui-Han Zhang, Tak-Pong Woo, Tzihong Chiueh
In the early Universe, large-scale flows were omnipresent, and the flow collisions produced sheets and filaments. This phenomenon occurs for both particle and wave dark matter. But…
How do stars affect DM halos?
James H. H. Chan, Hsi-Yu Schive, Tak-Pong Woo +1
Wave dark matter (DM) predicts a compact soliton core and a granular halo in every galaxy. This work presents the first simulation study of an elliptical galaxy by including bot…
Observation of quantum Hall plateau-plateau transition and scaling behavior of the zeroth Landau level in graphene p-n-p junctions
Cheng-Hua Liu, Po-Hsiang Wang, Tak-Pong Woo +6
We report distinctive magnetotransport properties of a graphene p-n-p junction prepared by controlled diffusion of metallic contacts. In most cases, materials deposited on a graphe…
Understanding the Core-Halo Relation of Quantum Wave Dark Matter, DM, from 3D Simulations
Hsi-Yu Schive, Ming-Hsuan Liao, Tak-Pong Woo +4
We examine the nonlinear structure of gravitationally collapsed objects that form in our simulations of wavelike cold dark matter (DM), described by the Schrödinger-Poisson (SP)…
Experimental evidence for direct insulator-quantum Hall transition in multi-layer graphene
Chiashain Chuang, Li-Hung Lin, Nobuyuki Aoki +7
We have performed magnetotransport measurements on a multi-layer graphene flake. At the crossing magnetic field Bc, an approximately temperature-independent point in the measured l…
