Abstract: On September 14th 2015, the LIGO
detectors opened a new window onto the universe with the first
direct detection of gravitational waves from a binary black hole
merger. This first event alone had profound implications for tests
of general...
I will provide an overview of the recent final data release of
the ESO Kilo-Degree Survey and the associated cosmology results
using weak gravitational lensing. As the field transitions to the
next generation of surveys with Euclid and Rubin, I will...
Massive black holes (MBHs) are found in galaxies across a wide
mass range and play a central role in regulating gas cooling and
star formation through active galactic nucleus (AGN) feedback.
Cosmological simulations—where MBHs and galaxies co-evolve...
Understanding the nature of dark matter is one of the major
goals of modern physics. The abundance and density profiles
of dark matter halos depend directly on dark matter particle
physics. Strong gravitational lensing enables a direct
measurement...
Collisionless shocks are ubiquitous in space and astrophysical
plasmas, where they often mediate conversion of flow energy into
particle acceleration and heating. In hot and rarified (weakly
collisional) plasmas, the energy dissipation must be...
Large-scale structure (LSS) surveys are a powerful probe of
primordial non-Gaussianity (PNG) and, by extension, inflation.
However, extracting PNG from small-scale LSS data is challenging
due to the significant non-Gaussianities generated by non...
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...
