The Supersonic Project: The eccentricity and rotational support of SIGOs and DM GHOSts
Claire E. Williams, Smadar Naoz, William Lake +7
A supersonic relative velocity between dark matter (DM) and baryons (the stream velocity) at the time of recombination induces the formation of low mass objects with anomalous prop…
Detecting Accelerating Eccentric Binaries in the LISA Band
Zeyuan Xuan, Smadar Naoz, Xian Chen
Many gravitational wave (GW) sources in the LISA band are expected to have non-negligible eccentricity. Furthermore, many of them can undergo acceleration because they reside in th…
Formation History of HD106906 and the Vertical Warping of Debris Disks by an External Inclined Companion
Nathaniel W. H. Moore, Gongjie Li, Lee Hassenzahl +3
HD106906 is a planetary system that hosts a wide-orbit companion, as well as an eccentric and flat debris disk, which hold important constraints on its formation and subsequent evo…
The Supersonic Project: The Early Evolutionary Path of SIGOs
William Lake, Smadar Naoz, Blakesley Burkhart +7
Supersonically Induced Gas Objects (SIGOs) are a class of early Universe objects that have gained attention as a potential formation route for globular clusters. SIGOs have only re…
Tidal disruption events from eccentric orbits and lessons learned from the noteworthy ASASSN-14ko
Chang Liu, Brenna Mockler, Enrico Ramirez-Ruiz +5
Stars grazing supermassive black holes (SMBHs) on bound orbits may survive tidal disruption, causing periodic flares. Inspired by the recent discovery of the periodic nuclear trans…
Ultra wide black-hole - neutron star binaries as a possible source for gravitational waves and short gamma ray bursts
Erez Michaely, Smadar Naoz
The third observing run of the LIGO/Virgo/KARGA collaboration reported a few neutron star - black hole (NSBH) merger events. While NSBH mergers have yet to receive extensive theore…
