摘要

The initial data from the Event Horizon Telescope (EHT) on M87*, the supermassive black hole at the center of the M87 Galaxy, provide direct observational information on its mass, spin, and accretion disk properties. A combination of the EHT data and other constraints provides evidence that M87* has a mass similar to 6.5 x 10(9) M-circle dot. EHT also inferred the dimensionless spin parameter vertical bar a*vertical bar greater than or similar to 0.5 from jet properties; a separate recent analysis using only the light from near M87* as measured by the EHT Collaboration found vertical bar a*vertical bar=0.9 +/- 0.1. These determinations disfavor ultralight bosons of mass mu(b) is an element of (0.85; 4.6) x 10(-21) eV for spin-one bosons and mu(b) is an element of (2.9; 4.6) x 10(-21) eV for spin-zero bosons, within the range considered for fuzzy dark matter, invoked to explain dark matter distribution on approximately kiloparsec scales. Future observations of M87* could be expected to strengthen our conclusions.

Bumblebee Black Holes in Light of Event Horizon Telescope Observations

Rui Xu, Dicong Liang, Lijing Shao

Summary: We present novel static spherical black hole solutions in the bumblebee gravity model, where the vector nonminimally couples to the Ricci curvature tensor, extending the Einstein-Maxwell theory. By testing these solutions in the strong-field regime using recent observations of supermassive black hole shadows in M87 and the Milky Way, we find that the parameter space is largely unexcluded, indicating the need for further experiments to fully constrain the theory.

Variational Image Feature Extraction for the Event Horizon Telescope

Paul Tiede, Avery E. Broderick, Daniel C. M. Palumbo

Summary: This paper presents a new image feature-extraction technique called variational image domain analysis, which can be applied to various VLBI image reconstructions and measure features such as diameter, orientation, and ellipticity. It demonstrates its flexibility by analyzing previous synthetic data sets and recovering astrophysically relevant quantities like the mass and orientation of the central black hole in M87.

Testing multiflavored ultralight dark matter models with SPARC

Lauren Street, Nickolay Y. Gnedin, L. C. R. Wijewardhana

Summary: By comparing maximum likelihood estimates for different cold dark matter (CDM) models, this study finds that the Burkert and Einasto models perform better than other commonly used CDM models. For ultralight dark matter (ULDM) models, most galaxies prefer particle masses in the range of 10-23 eV < m < 10-20 eV. In double flavor models, galaxies tend to prefer approximately equal particle masses.

Unveiling time-varying signals of ultralight bosonic dark matter at collider and beam dump experiments

Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie

Summary: The ultralight boson is a potential dark matter candidate with unique wave-like behaviors. We propose a method to detect ultralight dark matter using dark mediators in collider and beam dump experiments, distinguishing it from conventional methods. The time-varying nature of dark mediator mass reduces traditional constraints and enhances sensitivity compared to the time-blind method, also proving effective in detecting invisible decay.

Multifield ultralight dark matter

Mateja Gosenca, Andrew Eberhardt, Yourong Wang, Benedikt Eggemeier, Emily Kendall, J. Luna Zagorac, Richard Easther

Summary: Ultralight dark matter (ULDM) is usually assumed to be a single scalar field, but we explore the possibility that it consists of N light scalar fields with only gravitational interactions, which is more consistent with the underlying particle physics motivations for these scenarios. In multifield simulations, we find that the amplitude of the total density fluctuations inside a ULDM halo decreases as 1/sqrt(N) and the fields do not significantly correlate over cosmological timescales. Smoother halos heat stellar orbits less efficiently, weakening the observational constraints on the field mass.

Ultralight fermionic dark matter

Hooman Davoudiasl, Peter B. Denton, David A. McGady

Summary: The conventional lore excludes fermionic dark matter with mass lighter than a few hundred electronvolts based on the Pauli exclusion principle. A new method is proposed in this paper which involves numerous quasi-degenerate species of fermions without couplings to the standard model to evade this bound. Gravitational interactions impose constraints from measurements at the LHC, cosmic rays, supernovae, and black hole spins and lifetimes, with a particular limit on the number of distinct species of particles being less than or around 10^62.

Horizonless Spacetimes As Seen by Present and Next-generation Event Horizon Telescope Arrays

Astrid Eichhorn, Roman Gold, Aaron Held

Summary: We study the ability of present and future radio very long baseline interferometry arrays to differentiate between black holes and horizonless spacetimes. By considering an example of a horizonless spacetime created by overspinning a regular black hole, we find that its image differs from that of a Kerr spacetime due to the presence of additional photon rings within the shadow. Although these photon rings cannot be directly resolved by current or next-generation Event Horizon Telescope arrays, they leave an imprint in horizon-scale images as an excess central brightness compared to that of a black hole. We demonstrate that future arrays can decrease the upper limit of central brightness depression by a factor of 10, enabling the detection of such indirect imprints from non-Kerr spacetimes in reconstructed images.

Rotation in Event Horizon Telescope Movies

Nicholas S. Conroy, Michi Baubock, Vedant Dhruv, Daeyoung Lee, Avery E. Broderick, Chi-kwan Chan, Boris Georgiev, Abhishek V. Joshi, Ben Prather, Charles F. Gammie

Summary: The EHT has captured images of M87* and Sagittarius A*, and will soon capture time sequences of images. A technique to measure the rotation rate from movies is described and validated on simulated images of Sgr A*. The predicted rotation rate of the EHT movies is 15% of the Keplerian orbital frequency in the emitting region, and it depends strongly on inclination.

Asteroids for ultralight dark-photon dark-matter detection

Michael A. Fedderke, Anubhav Mathur

Summary: Gravitational-wave detectors can detect new forces acting on test masses through the fluctuations in their separation. A recent proposal based on monitoring the separation of certain asteroids in the inner Solar System would provide sensitivity to mu Hz frequencies and allow exploration of the parameter space for dark matter. However, noise issues associated with asteroid rotational motion need to be overcome for sensitivity to be extended to higher mass ranges.

Ultralight pion and superheavy baryon dark matter

Azadeh Maleknejad, Evan McDonough

Summary: In this study, a dark confining gauge theory with millicharged ultralight pions and heavy baryons as dark matter candidates is considered. The model combines the ultralight and superheavy dark matter paradigms through the confinement scale of dark QCD. It is found that the model provides a realization of millicharged ultralight dark matter, with a mass splitting between charged and neutral pions. The results show that the accessible parameter space of the model is larger compared to conventional millicharged dark matter scenarios and can be probed by future experiments.

Supermassive Black Holes, Ultralight Dark Matter, and Gravitational Waves from a First Order Phase Transition

Hooman Davoudiasl, Peter B. Denton, Julia Gehrlein

Summary: This paper presents a model that explores the connection between the formation of supermassive black holes and ultralight dark matter in the early Universe. By considering a confining first order phase transition at a temperature of around 10 keV, the production of primordial supermassive black holes with masses of 10^9 solar masses is facilitated. This phase transition also suggests a possible mass for a motivated ultralight axion dark matter candidate. Additionally, the assumed first order phase transition is expected to generate primordial gravitational waves in the frequency range of around 10^(-12)-10^(-9) Hz, which could be detectable by pulsar timing arrays.

Summary: Neutrinos, the least understood particles in the Standard Model, have weak interactions with other particles. The self-interactions of neutrinos, which are not well-known, are predicted by the Standard Model to exceed current experimental capabilities, allowing for potential interactions beyond the Standard Model at various energy scales. This white paper reviews the current knowledge of neutrino self-interactions from a range of probes, including cosmology, astrophysics, and laboratory experiments. Theoretical motivations, such as neutrino masses and connections to dark matter, are also discussed. The paper discusses future search capabilities, emphasizing the possibility of discovering beyond the Standard Model physics.

Sterile neutrino shape shifting caused by dark matter

Hooman Davoudiasl, Peter B. Denton

Summary: This study proposes a cosmologically viable proposal that is consistent with terrestrial experiments and solar constraints, by sourcing the mass of unobservable sterile neutrinos with a mass of -1 eV from an ultralight scalar field Φ. In this scenario, the experimentally implied -1 eV sterile neutrino mass is a local value and changes throughout spacetime.

Summary: Neutrinos are potential messengers for new physics beyond the Standard Model, as their elusive nature and unknown mass mechanism suggest the opening of a window to new physics in the neutrino sector. Long-standing anomalies reported in the past decades provide strong motivation to thoroughly test the standard three-neutrino oscillation paradigm in current and future neutrino experiments. This Snowmass21 white paper explores the potential of these experiments to investigate new physics effects on neutrino flavor during the next decade.

New constraints on the dark side of non-standard interactions from reactor neutrino scattering data

Peter B. Denton, Julia Gehrlein

Summary: This article mainly introduces the degeneracies in neutrino oscillation physics, known as LMA-Dark, which make it impossible to determine the atmospheric mass ordering using oscillation experiments alone. By combining different measurements, the degeneracies can be lifted to some extent. New data from the Dresden-II experiment are used to completely remove the degeneracies in the ν(e) sector at the MeV scale. However, the LMA-Dark degeneracy can still be restored in the ν(μ) and ν(τ) sectors.

Parameter symmetries of neutrino oscillations in vacuum, matter, and approximation schemes

Peter B. Denton, Stephen J. Parke

Summary: This article investigates the parameter symmetries in neutrino oscillations and discovers different symmetries for vacuum parameters and matter parameters. The effects of these symmetries on physical observables and the improvement of precision in approximate expressions are also explored.
