Abstract: Gravitational waves have uncovered a treasure trove of nearly 90 merging black holes and neutron stars, each with its own unique story to tell. In the first part of the talk, our focus will center on black hole spins, seeking to decipher...

Binaries are ubiquitous in various scales and astrophysical systems, from planetesimals to black holes, and play a key role in the dynamics and evolution of stellar systems. I will discuss the formation and evolution of binaries in gaseous...

Charge-exchange (CX) collisions of the solar wind (SW) high-ionization-state minor ions with LISM neutrals are responsible for much of X-ray production in the outer heliosphere. In this talk, we discuss numerical modeling of the heliospheric CX X...

Current cosmological measurements have left us with deep questions about our Universe: What caused the expansion of the Universe at the earliest times? How did structure form? What is Dark Energy and does it evolve with time? New experiments like...

Pulsar timing arrays {PTAs) and gravitational wave detectors can serve as valuable tools in the detection of dark matter. Dark matter substructure within the Milky Way Galaxy can induce gravitational pulls on pulsars, leading to observable...

Despite the thousands of planets discovered orbiting stars on the main sequence, the planetary systems of more evolved stars remain poorly understood. Studying planetary systems around subgiant and red giant stars can reveal how planetary systems...

In this talk, I will focus on the emission signatures we can expect from magnetospheres of compact objects, with a strong focus on pulsars. In the first part of the talk, I will describe the evolution of a three-dimensional collisionless...

Abstract: The existence of an event horizon is the defining property of a black hole. I shall review the properties of event horizons and discuss various examples demonstrating that event horizons are not smooth in dynamical processes such as black...

The restless central engine of accreting supermassive black holes produces ubiquitous variability across broad ranges of wavelengths and timescales. Variability allows the study of the innermost structures around the SMBH that cannot be spatially...
