Ultraviolet Quasi-periodic Eruptions from Star-Disk Collisions in Galactic Nuclei
Itai Linial, Brian D. Metzger
``Quasi-periodic eruptions'' (QPE) are recurrent nuclear transients with periods of several hours to almost a day, which thus far have been detected exclusively in the X-ray band.…
Period Evolution of Repeating Transients in Galactic Nuclei
Itai Linial, Eliot Quataert
Wide-field survery have recently detected recurring optical and X-ray sources near galactic nuclei, with period spanning hours to years. These phenomena could result from repeated…
Energy Flux and Particle Flux in Steady-State Solutions of Nuclear Star Clusters
Barak Rom, Itai Linial, Re'em Sari
We examine the effects of two-body interactions in a nuclear star cluster surrounding a supermassive black hole. We evaluate the energy flux, analogously to the particle flux calcu…
Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants
Sanaea C. Rose, Smadar Naoz, Re'em Sari +1
Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can oc…
EMRI + TDE = QPE: Periodic X-ray Flares from Star-Disk Collisions in Galactic Nuclei
Itai Linial, Brian D. Metzger
Roughly half of the quasi-periodic eruption (QPE) sources in galactic nuclei exhibit a remarkably regular alternating "long-short'' pattern of recurrence times between consecutive…
