Raising the Optical Depth to Reionization with Dark Matter Decay
Yu-Ning Wang, Paulo Montero-Camacho, Ziwei Wang +2
DESI DR2 baryon acoustic oscillation (BAO) measurements have sharpened a discrepancy with cosmic microwave background (CMB) inferences that can be recast as a preference for $τ_{\r…
The impact of primordial magnetic fields on the formation of galaxies
Yao-Yu Li, Shihong Liao, Yue-Lin Sming Tsai +1
Primordial magnetic fields (PMFs), potentially generated during cosmic inflation or early-universe phase transitions, can modify cosmic structure formation by enhancing the post-re…
Milky Way Dynamics Favor Dark Matter over Modified Gravity Models
Zheng-long Wang, Yue-Lin Sming Tsai, Lan Zhang +5
Modified gravity theories such as Modified Newtonian Dynamics (MOND) and Scalar-Tensor-Vector Gravity (STVG) have been proposed as alternatives to dark matter, but decisive tests h…
Cosmology of Inelastic Self-Interacting Dark Matter: Linear Evolution and Observational Constraints
Xin-Chen Duan, Yue-Lin Sming Tsai, Ziwei Wang
We study the linear cosmological evolution of inelastic self-interacting dark matter in a two-component dark sector with a small mass splitting, assuming thermal initial conditions…
Probing Cosmic-Ray-Boosted and Supernova-Sourced Sub-GeV Dark Matter with Paleo-Detectors
Xiaoyong Chu, Yue-Lin Sming Tsai, Mei-Wen Yang
Astrophysical dark matter particles with masses well below GeV-scale can be difficult to detect using conventional nuclear recoil experiments due to their low velocities in our Mil…
Challenges in Binary Pulsar Timing Detection of Dark Matter Subhalos
Zheng-Long Wang, Zi-Qing Xia, Yue-Lin Sming Tsai +1
Recently, binary pulsar timing has been proposed as a viable probe of dark matter subhalos with masses of in the solar neighborhood. We present a comprehensi…
Flux-ratio anomalies in cusp quasars reveal dark matter beyond CDM
Siyuan Hou, Shucheng Xiang, Yue-Lin Sming Tsai +7
Strongly lensed quasars in cusp configurations provide a uniquely sensitive probe of small-scale dark matter structure. Using the largest microlensing-free flux ratios for 17 quadr…
Dark-Matter-Deficient Galaxies from Collisions: A New Probe of Bursty Feedback and Dark Matter Physics
Yi-Ying Wang, Daneng Yang, Keyu Lu +2
High-velocity collisions between gas-rich ultra-diffuse galaxies present a promising formation channel for dark-matter-deficient galaxies (DMDGs). Using hydrodynamical simulations,…
Constraints on axionlike particles from 16.5 years of Fermi-LAT data and prospects for VLAST
Zhi-Qi Guo, Yue-Lin Sming Tsai, Lei Wu +1
Axionlike particles (ALPs), hypothetical particles beyond the Standard Model, are considered as promising dark matter candidates. ALPs can convert into photons and vice versa in a…
Self-Interacting Dark Matter with Mass Segregation: A Unified Explanation of Dwarf Cores and Small-Scale Lenses
Daneng Yang, Yi-Zhong Fan, Siyuan Hou +1
In two-component self-interacting dark matter (SIDM) models with inter-species interactions, mass segregation arises naturally from collisional relaxation, enhancing central densit…
Prospects for Probing Sub-GeV Leptophilic Dark Matter with the Future VLAST
Tian-Peng Tang, Meiwen Yang, Kai-Kai Duan +2
The proposed Very Large Area Space Telescope (VLAST), with its expected unprecedented sensitivity in the MeV-GeV range, can also address the longstanding "MeV Gap" in gamma-ray obs…
Revisiting open clusters within 200 pc in the solar neighbourhood with Gaia DR3
Penghui Liu, Min Fang, Yue-Lin Sming Tsai +3
In this study, we develop a membership identification method and apply it for 30 open clusters (OCs) within 200 pc of the Sun using astrometric data of Gaia DR3. By accounting for…
Diversifying halo structures in two-component self-interacting dark matter models via mass segregation
Daneng Yang, Yue-Lin Sming Tsai, Yi-Zhong Fan
Self-interacting dark matter (SIDM), through gravothermal evolution driven by elastic self-scatterings, offers a compelling explanation for the observed diversity of inner halo den…

We revisit constraints on sub-GeV dark matter (DM) annihilation via -wave, -wave, and resonance processes using current and future CMB data from Planck, FIRAS, and upcoming e…
A solution to the S8 tension through neutrino-dark matter interactions
Lei Zu, William Giarè, Chi Zhang +3
Neutrinos and dark matter (DM) are two of the least understood components of the Universe, yet both play crucial roles in cosmic evolution. Clues about their fundamental properties…
