Dark Bondi Accretion Aided by Baryons and the Origin of JWST Little Red Dots
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
The gravothermal core collapse of self-interacting dark matter halos provides a mechanism for seeding supermassive black holes in the early Universe. We show that the collapse of a…
The impact of baryonic potentials on the gravothermal evolution of self-interacting dark matter haloes
Yi-Ming Zhong, Daneng Yang, Hai-Bo Yu
The presence of a central baryonic potential can have a significant impact on the gravothermal evolution of self-interacting dark matter (SIDM) haloes. We extend a semi-analytical…
A Parametric Model for Self-Interacting Dark Matter Halos
Daneng Yang, Ethan O. Nadler, Hai-Bo Yu +1
We propose a parametric model for studying self-interacting dark matter (SIDM) halos. The model uses an analytical density profile, calibrated using a controlled N-body SIDM simula…
A quantitative comparison between velocity dependent SIDM cross sections constrained by the gravothermal and isothermal models
Shengqi Yang, Fangzhou Jiang, Andrew Benson +6
One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SI…
Super-sample covariance of the power spectrum, bispectrum, halos, voids, and their cross covariances
Adrian E. Bayer, Jia Liu, Ryo Terasawa +3
We study the effect of super-sample covariance (SSC) on the power spectrum and higher-order statistics: bispectrum, halo mass function, and void size function. We also investigate…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
A Phantom Menace: On the Morphology of the Galactic Center Excess
Samuel D. McDermott, Yi-Ming Zhong, Ilias Cholis
The characteristics of the Galactic Center Excess (GCE) emission observed in gamma-ray energies -- especially the morphology of the GCE -- remain a hotly debated subject. The manne…
Constraining resonant dark matter self-interactions with strong gravitational lenses
Daniel Gilman, Yi-Ming Zhong, Jo Bovy
We devise a method to constrain self-interacting dark matter (SIDM) from observations of quadruply-imaged quasars, and apply it to five self-interaction potentials with a long-rang…
Tripling down on the boson mass
Henning Bahl, Wen Han Chiu, Christina Gao +2
A new precision measurement of the boson mass has been announced by the CDF collaboration, which strongly deviates from the Standard Model prediction. In this article, we study…
Snowmass2021 Computational Frontier White Paper: Cosmological Simulations and Modeling
Marcelo A. Alvarez, Arka Banerjee, Simon Birrer +9
Powerful new observational facilities will come online over the next decade, enabling a number of discovery opportunities in the "Cosmic Frontier", which targets understanding of t…
Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark Matter Searches and How to Resolve Them
Rebecca K. Leane, Seodong Shin, Liang Yang +36
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Ast…
The Return of the Templates: Revisiting the Galactic Center Excess with Multi-Messenger Observations
Ilias Cholis, Yi-Ming Zhong, Samuel D. McDermott +1
The Galactic center excess (GCE) remains one of the most intriguing discoveries from the Fermi Large Area Telescope (LAT) observations. We revisit the characteristics of the GCE by…
Precision Calculation of Inflation Correlators at One Loop
Lian-Tao Wang, Zhong-Zhi Xianyu, Yi-Ming Zhong
We initiate a systematic study of precision calculation of the inflation correlators at the 1-loop level, starting in this paper with bosonic 1-loop bispectrum with chemical-potent…
Dynamical Instability of Collapsed Dark Matter Halos
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
A self-interacting dark matter halo can experience gravothermal collapse, resulting in a central core with an ultrahigh density. It can further contract and collapse into a black h…
A necessary condition for supernova fallback invading newborn neutron-star magnetosphere
Yici Zhong, Kazumi Kashiyama, Toshikazu Shigeyama +1
We numerically investigate the dynamics of a supernova fallback accretion confronting with a relativistic wind from a newborn neutron star (NS). The time evolution of the accretion…
Exotic Decays of the 125 GeV Higgs Boson
David Curtin, Rouven Essig, Stefania Gori +10
We perform an extensive survey of non-standard Higgs decays that are consistent with the 125 GeV Higgs-like resonance. Our aim is to motivate a large set of new experimental analys…
Supersymmetric Exotic Decays of the 125 GeV Higgs Boson
Jinrui Huang, Tao Liu, Lian-Tao Wang +1
We reveal a set of novel decay topologies for the 125 GeV Higgs boson in supersymmetry which are initiated by its decay into a pair of neutralinos, and discuss their collider searc…
