Wandering intermediate-mass black holes and off-nuclear tidal disruption events from early star clusters
Claire E. Williams, Smadar Naoz, Yihao Zhou +9
Off-nuclear tidal disruption events (TDEs) reveal evidence for massive black holes outside galactic centers, but the origins of this wandering population remain uncertain. We inves…
Radiative Feedback in Population III Protostellar Growth: HI Shielding and HII Region Trapping
Avi Chen, Shyam H. Menon, Blakesley Burkhart +7
We present a suite of radiation-magnetohydrodynamics simulations from the Popsicle project that follow the long-term growth ( kyr) of primordial protostars while self-cons…
Observing compact Pop III star clusters and the presence of cosmic streaming
Claire E. Williams, Smadar Naoz, Naoki Yoshida +7
The formation of the Universe's first luminous stellar structures depends on the unique conditions at "Cosmic Dawn," which are set by the underlying cosmological model and early ba…
Supersonic Turbulence in Primordial Halos: A Comparison With and Without The Stream Velocity
Avi Chen, William Lake, Claire E. Williams +6
Turbulence plays a critical role in regulating star formation in molecular clouds and is also observed in simulations of primordial halos that host Population III (Pop III) stars.…
CDM star clusters at cosmic dawn: stellar densities, environment, and equilibrium
Claire E. Williams, Smadar Naoz, William Lake +7
The James Webb Space Telescope (JWST) has opened a window on many new puzzles in the early Universe, including a population of high-redshift star clusters with extremely high stell…
The Stellar Initial Mass Function of Early Dark Matter-free Gas Objects
William Lake, Michael Y. Grudić, Smadar Naoz +6
Among the remarkable strides made by JWST is the discovery of the earliest star clusters found to date. These have been proposed as early progenitors of globular clusters, which ar…
The Supersonic Project: Early Star Formation with the Streaming Velocity
William Lake, Claire E. Williams, Smadar Naoz +7
At high redshifts (), the relative velocity between baryons and dark matter (the so-called streaming velocity) significantly affects star formation in low-mass objects.…
The Supersonic Project: Lighting up the faint end of the JWST UV luminosity function
Claire E. Williams, William Lake, Smadar Naoz +9
The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities…
The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter
William Lake, Smadar Naoz, Federico Marinacci +7
The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that Supersonically Induced Gas Objects (SIGOs), which formed in t…
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…
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…
cooling and gravitational collapse of supersonically induced gas objects
Yurina Nakazato, Gen Chiaki, Naoki Yoshida +3
We study the formation and gravitational collapse of supersonically induced gas objects (SIGOs) in the early universe. We run cosmological hydrodynamics simulations of SIGOs, inclu…
The Supersonic Project: SIGOs, a Proposed Progenitor to Globular Clusters, and their Connections to Gravitational Wave Anisotropies
William Lake, Smadar Naoz, Yeou S. Chiou +4
Supersonically Induced Gas Objects (SIGOs), are structures with little to no dark matter component predicted to exist in regions of the Universe with large relative velocities betw…
