We study complex saddle points of the worldline path integral for massive charged particles in two-dimensional maximally symmetric backgrounds threaded by homogeneous electric fiel…
Rethinking Thorne-Żytkow Object Formation: The Fate of X-ray Binary LMC X-4 and Implications for Ultra-long Gamma-ray Bursts
Tenley Hutchinson-Smith, Rosa Wallace Everson, Angela A. Twum +5
We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether a Thorne-Żytkow object (TŻO) might ultimately be assembled. We ana…
Astrophysical Constraints on Decaying Dark Gravitons
Jamie A. P. Law-Smith, Georges Obied, Anirudh Prabhu +1
In the dark dimension scenario, which predicts an extra dimension of micron scale, dark gravitons (KK modes) are a natural dark matter candidate. In this paper, we study observable…
Mid-Infrared Outbursts in Nearby Galaxies: Nuclear Obscuration and Connections to Hidden Tidal Disruption Events and Changing-Look Active Galactic Nuclei
Sierra A. Dodd, Arya Nukala, Isabelle Connor +5
We study the properties of galaxies hosting mid-infrared outbursts in the context of a catalog of five hundred thousand galaxies from the Sloan Digital Sky Survey. We find that nuc…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
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…
Point Containment Queries on Ray Tracing Cores for AMR Flow Visualization
Stefan Zellmann, Daniel Seifried, Nate Morrical +5
Modern GPUs come with dedicated hardware to perform ray/triangle intersections and bounding volume hierarchy (BVH) traversal. While the primary use case for this hardware is photor…
Evidence for the preferential disruption of moderately massive stars by supermassive black holes
Brenna Mockler, Angela A. Twum, Katie Auchettl +4
Tidal disruption events (TDEs) provide a unique opportunity to probe the stellar populations around supermassive black holes (SMBHs). By combining light curve modeling with spectra…
Successful Common Envelope Ejection and Binary Neutron Star Formation in 3D Hydrodynamics
Jamie A. P. Law-Smith, Rosa Wallace Everson, Enrico Ramirez-Ruiz +10
A binary neutron star merger has been observed in a multi-messenger detection of gravitational wave (GW) and electromagnetic (EM) radiation. Binary neutron stars that merge within…
The Landscape of Galaxies Harboring Changing-Look Active Galactic Nuclei in the Local Universe
Sierra A. Dodd, Jamie A. P. Law-Smith, Katie Auchettl +2
We study the properties of the host galaxies of Changing-Look Active Galactic Nuclei (CL AGNs) with the aim of understanding the conditions responsible for triggering CL activity.…
The Young Supernova Experiment: Survey Goals, Overview, and Operations
D. O. Jones, R. J. Foley, G. Narayan +68
Time domain science has undergone a revolution over the past decade, with tens of thousands of new supernovae (SNe) discovered each year. However, several observational domains, in…
Obstacles to Constructing de Sitter Space in String Theory
Michael Dine, Jamie A. P. Law-Smith, Shijun Sun +2
There have been many attempts to construct de Sitter space-times in string theory. While arguably there have been some successes, this has proven challenging, leading to the de Sit…
Stellar Tidal Disruption Events with Abundances and Realistic Structures (STARS): Library of Fallback Rates
Jamie A. P. Law-Smith, David A. Coulter, James Guillochon +2
We present the STARS library, a grid of tidal disruption event (TDE) simulations interpolated to provide the mass fallback rate () to the black hole for a main-sequence star…
The Process of Stellar Tidal Disruption by Supermassive Black Holes. The first pericenter passage
Elena M. Rossi, Nicholas C. Stone, Jamie A. P. Law-Smith +4
Tidal disruption events (TDEs) are among the brightest transients in the optical, ultraviolet, and X-ray sky. These flares are set into motion when a star is torn apart by the tida…
The Host Galaxies of Tidal Disruption Events
K. Decker French, Thomas Wevers, Jamie Law-Smith +2
Recent studies of Tidal Disruption Events (TDEs) have revealed unexpected correlations between the TDE rate and the large-scale properties of the host galaxies. In this review, we…
