Armin Sadeghi

Welcome

I'm Armin, currently a PhD candidate at the University of Tehran. My main academic interests lie in gravitational physics and astrophysics. At the moment, I'm focused on studying regular black holes—after all, singularities are quite problematic, aren't they?

Lately, I've become particularly interested in relativistic jets and accretion disks in active galactic nuclei (AGNs) and other massive compact objects. I'm excited about the prospect of applying theoretical insights from general relativity to real astrophysical phenomena.

Outside of physics, I have a deep appreciation for classical and rock music, and I enjoy exploring philosophy and psychology.

If you wish to contact me, do not hesitate to email me.
