Emission line formation in scattering dominated media: implications for LRDs
Elisha Modelevsky, Omri Nitzan, Re'em Sari +1
Recent JWST observations of ``Little Red Dots'' (LRDs) reveal broad and prominent Balmer emission lines. We present a theoretical framework for intrinsic emission line formation an…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
The paper models the orbital evolution of the S‑star cluster around the Milky Way’s central black hole using a superdiffusive, fractional transport framework that accounts for long…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
The paper studies how the rotation of the S301 star near the Galactic Center can act as a macroscopic gyroscope, using its relativistic precession to test general relativity with i…
Dynamics in Nuclear Stellar Clusters: The Impact of Collisions and Disrupted Binaries
Barak Rom, Re'em Sari
The paper investigates how stellar collisions and disrupted binaries influence the stellar distribution around supermassive black holes, finding a steady‑state r⁻⁵/⁴ density profil…
Evolution of Stars During the Main Sequence and the Transition to the Red Giant Phase
Ravid Achituv, reem sari
We derive a simple analytical description for the structure and evolution of -- stars throughout main-sequence hydrogen burning. We obtain an analytical relation for…
The - Relation Has to Break
Omri Nitzan, Re'em Sari
We revisit the growth of central black holes via tidal disruption events (TDEs) and plunges of stellar-mass black holes (sBHs). Our model incorporates the current understanding of…
