Revealing Dark Matter under the Lens
Unveiling the true nature of Dark Matter (DM), which manifests itself only through gravity, is one of the principal quests in physics. Leading candidates for DM are weakly interacting massive particles (WIMPs) or ultralight bosons (axions), at opposite extremes in mass scales, that have been postulated by competing theories to solve deficiencies in the Standard Model of particle physics. Wherea...

Photoionization models with turbulent structures
Turbulence features ubiquitously in the interstellar medium, especially in the high-redshift Universe. Photoionization models with turbulent ISM density fields can predict nebular emission lines more realistically than the former uniform density/pressure photoionization models. In this talk, we will briefly introduce a turbulent photoionization model grid created by the cutting-edge 3D Monte Ca...

Planet Formation near the Inner Disk Edge
Short-period super-Earths and sub-Neptunes are the most abundant type of planets. Their origin is key to understanding planet formation and the evolution of protoplanetary disks. Recent observations found that, contrary to mature systems, young planetary systems appear to be dominated by near-resonant configurations, suggesting a rich history of resonance capture followed by secular dynamical i...

Cracking neutron star mysteries: Physics-driven insights into interior, surface, and exterior by X-ray Timing results
The utilization of Pulse Profile modeling techniques could simultaneously provide measurements for Neutron star Mass Radius and offer insights into their hotspot distribution. Presently, these methodologies rely on meta models of the equation of state (EOS) and employ pure geometrical cap overlapping techniques to align with observational data. This presentation aims to showcase our recent resu...

Accreting massive black holes and a Czech UV space telescope
Most galaxies comparable to or larger than the mass of the Milky Way host hot, X-ray emitting atmospheres and accreting supermassive black holes. Hot atmospheres and radio jets and lobes are the ingredients of radio-mechanical active galactic nucleus (AGN) feedback. At least half of the most massive early-type galaxies harbour multi-phase filamentary gas, which appears to result from the therm...
