A Dark Matter Masquerade: Degeneracies in Black Hole and Accretion Inference from X-ray Reflection Measurements and Prospects for Compact Dark Matter Halo Constraints
Leif Lui, Zijian Zhang, Alejandro Torres-Orjuela
X-ray reflection spectroscopy is an established probe of black hole (BH) spin and accretion geometry, and many studies have examined its systematic uncertainties. In this work, we…
Little red dots as a cosmological probe: constraining with quasi-periodic pulsations
Zijian Zhang, Kohei Inayoshi, Masamune Oguri +4
The James Webb Space Telescope (JWST) has uncovered a population of ``little red dots'' (LRDs) at , potentially representing early supermassive black holes embedded in…
ABCD: The Nuclear Structure of the Little Red Dots Revealted through Absorption, Break, Continuum, and Decrement
Chang-Hao Chen, Jinyi Shangguan, Luis C. Ho +3
We present a spectroscopic analysis of 14 little red dots (LRDs) at redshifts using NIRSpec/MSA prism and medium-resolution grating observations, aiming to constrai…
COSMOS-3D: Black Hole Mass Estimators and Luminosity Functions of Paschen-line AGNs
Danyang Jiang, Linhua Jiang, Shuqi Fu +13
Near-IR Paschen lines are potentially an excellent tracer of Type 1 AGNs that is hardly affected by dust extinction. JWST allows us, for the first time, to explore Paschen-line obj…
Local Analogs of Little Red Dots: Optical Variability and Evidence for an Active Galatic Nucleus Origin
Ruqiu Lin, Zhen-Ya Zheng, Junxian Wang +9
Little red dots (LRDs) draw extensive attention because of their unique observational characteristics and apparent overabundance in the early Universe, raising new insights into ea…
On the Variability Features of Active Galactic Nuclei in Little Red Dots
Shuying Zhou, Mouyuan Sun, Zijian Zhang +2
The high-redshift () compact sources with ``V-shaped" spectral energy distributions (SEDs), known as Little Red Dots (LRDs), are discovered by the James Webb Space Telescope a…
