High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array
Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20
The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…
Scalar Spatiotemporal Blue Noise Masks
Alan Wolfe, Nathan Morrical, Tomas Akenine-Möller +1
Blue noise error patterns are well suited to human perception, and when applied to stochastic rendering techniques, blue noise masks (blue noise textures) minimize unwanted low-fre…
The DESI -body Simulation Project I: Testing the Robustness of Simulations for the DESI Dark Time Survey
Cameron Grove, Chia-Hsun Chuang, Ningombam Chandrachani Devi +19
Analysis of large galaxy surveys requires confidence in the robustness of numerical simulation methods. The simulations are used to construct mock galaxy catalogs to validate data…
Reionization in the Light of Dark Stars
Paolo Gondolo, Pearl Sandick, Barmak Shams Es Haghi +1
We investigate the effect of Dark Stars (DSs) on the reionization history of the Universe, and the interplay between them and feedback due to Lyman-Werner (LW) radiation in reducin…
Narrowband searches for continuous and long-duration transient gravitational waves from known pulsars in the LIGO-Virgo third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1658
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully-coherent s…
Minimizing Congestion for Balanced Dominators
Yosuke Mizutani, Annie Staker, Blair D. Sullivan
A primary challenge in metagenomics is reconstructing individual microbial genomes from the mixture of short fragments created by sequencing. Recent work leverages the sparsity of…
