An X-Ray Shell Reveals the Supernova Explosion for Galactic Microquasar SS 433

The Astrophysical Journal Letters
How black holes are formed remains an open and fundamental question in astrophysics. Despite theoretical predictions, it lacks observations to understand whether the black hole formation experiences a supernova explosion.

Unveiling the Small-scale Jets in the Rapidly Growing Supermassive Black Hole IZw1

The Astrophysical Journal
Accretion of black holes at near-Eddington or super-Eddington rates represents the most powerful episode driving black hole growth, potentially occurring across various types of objects.

Modeling High Mass X-Ray Binaries to Double Neutron Stars through Common Envelope Evolution

The Astrophysical Journal
We present detailed evolutionary simulations of wide binary systems with high-mass (8–20 M _⊙ ) donor stars and a 1.4 M _⊙ neutron star. Mass transfer in such binaries is dynamically unstable, and common envelope (CE) evolution is followed.

General Relativistic Radiation Magnetohydrodynamics Simulations of Precessing Tilted Super-Eddington Disks

The Astrophysical Journal
We perform a three-dimensional general relativistic radiation magnetohydrodynamics simulation of a tilted super-Eddington accretion disk around a spinning black hole (BH).
