In-Situ Star Formation in a Thick Disk: A Model for Metal Enrichment of Mrk 573
Hannalore J. Gerling-Dunsmore, Mitchell C. Begelman, Jared A. Goldberg +2
Recent observations of the nearby Seyfert galaxy Mrk 573 found that the galactic nucleus and bicone regions surrounding the jet are significantly metal-enriched. In this paper, we…
White Dwarf Natal Kicks as Velocity-Space Random Walks. I. Fokker-Planck Theory
Stephen Majeski, Dang Pham, Taeho Ryu +2
White dwarfs are the most common end state of stellar evolution, including that of our own Sun, making their formation critical to completing a more comprehensive understanding of…
White Dwarf Natal Kicks as Velocity-Space Random Walks. II. Binary Stellar Evolution and Observational Kick Constraints
Dang Pham, Stephen Majeski, Taeho Ryu +2
Wide binaries containing white dwarfs (WDs) provide a pathway to exploring post-main-sequence (MS) natal kicks associated with asymmetric mass loss. In this work, we develop a bina…
Signatures of Compact Object Mergers Inside Stars in AGN Disks
Matteo Cantiello, Alexander J. Dittmann, Saavik Ford +4
Disks of gas accreting onto supermassive black holes, powering active galactic nuclei (AGN), can capture stars from nuclear star clusters or form stars in situ via gravitational in…
Explaining the X-ray Precursor, Ultra-long Prompt Emission, and Week-long Decay of GRB250702B with a Jetted Micro-TDE
Fulya Kıroğlu, Taeho Ryu, Alexander Tchekhovskoy +3
The longest detected gamma-ray burst, GRB250702B, exhibited seven hours of prompt -ray emission, preceded by a soft X-ray precursor ( day earlier) and followed by a weeks…
The TDE Population from First-Principles Models of Stellar Disruption and Debris Dynamics
Tsvi Piran, Julian Krolik, Taeho Ryu
We present a physically-grounded population model for optical tidal disruption events (TDEs) that combines first-principles hydrodynamic simulations of stellar disruption with stat…
