We present a multi-wavelength analysis of the gamma-ray emission mechanisms within blazar 3C 454.3. Using 12 years of gamma-ray data alongside multi-epoch VLBA observations at 15 and 43 GHz, we explore the correlation between jet features and gamma-ray activity. Our analysis reveals a significant correlation between gamma-ray flux and core emission at 43 GHz and 15 GHz, suggesting these core regio ... More

Nova outbursts are powerful astronomical events occurring in binary star systems, where a white dwarf accumulates material from its companion star until a critical pressure and temperature are reached and trigger a thermonuclear outburst. In this talk we'll focus on the well known recurrent and symbiotic nova RS Ophiuchi (RS Oph) that experienced a new outburst in August 2021, representing the fi ... More

Black hole X-ray binaries (BHXBs) are stellar-mass black holes in binary systems with stars, serving as laboratories for studying various astrophysical phenomena such as accretion-outflow mechanisms, jet launching processes, and binary evolution. With approximately 70 known systems in our Galaxy and 2-3 new discoveries annually, most studies focus on systems detected during outbursts when sudden c ... More

Observations of transient and episodic jets allow us to study jet formation and particle acceleration in real time. To better understand the possible physics behind these violent events we perform two-temperature 3D GRMHD simulations of accreting black holes. Our simulations start with an initial torus in hydrostatic equilibrium seeded with a magnetic field with alternating polarity. During the ac ... More

X-ray binaries provide nearby laboratories to study the launching and evolution of relativistic jets on human timescales. High angular resolution VLBI observations are critical in determining the motions of these jets, allowing us to track them back to their launch point and determine an ejection time. This can be compared with the contemporaneous X-ray behaviour to determine the causal connection ... More
