In the past decade, we have detected hundreds of gravitational
waves, advancing our understanding of the Universe and its
governing laws. In this talk, I will present the theoretical models
and data analysis tools I have developed for interfacing...
Gas-rich environments are ubiquitous in various scales, from
protoplanetary disks to star clusters and galaxies. Dynamics in
gas-rich environments are substantially different and give rise to
unique astrophysical phenomena, along with enhancing the...
Spatially resolved polarimetric images of black holes with the
Event Horizon Telescope (EHT) favor models with strong magnetic
fields, so-called Magnetically Arrested Disks or MAD models.
MADs can produce efficient jets via the Blandford-Znajek (BZ...
The alpha disk model is widely used to describe the accretion
disk structures around supermassive black holes, even though it
cannot explain many observed properties of AGNs. Various
alternative models have been proposed including the ones
where...
Deep generative models offer powerful tools for solving
astrophysical inference problems by enabling flexible
representations of prior knowledge and likelihood functions.
In the first part of the talk, I will discuss how generative
models can be...
The so-called galaxy--halo connection is a vast topic concerning
how galaxies populate their host dark matter halos. I will
present some works we have made under this grand theme, including
(1) the detection of assembly bias signal with the help of...
The first structures of particle dark matter form by
gravitationally condensing out of the smooth mass distribution of
the early universe. This formation mechanism leaves these "prompt
cusps" with uniquely compact r^-1.5 density profiles and
links...
Neutron stars born with magnetic fields greater than 1014 G
(“magnetars”) are common in the Galaxy. Approximately 10 - 50% of
the young neutron star population possesses such field strengths.
These objects exhibit very slow rotation, spectacular...
