Ultra-light axions are well-motivated fuzzy/wave cold dark matter (CDM) candidates that provide potential resolutions to various small-scale problems faced by conventional heavy particle CDM. Being wavy on astronomical scales, galaxy formation is suppressed below the respective de Broglie wavelength scale, resulting in a sharp turnover in galaxy luminosity functions (LF) at the faint end. Such...
We investigate a neutrino-scalar dark matter (DM) $νϕ$ interaction encountering distinctive neutrino sources, namely Diffuse Supernova Neutrino Background (DSNB) and Active Galactic Nuclei (AGN). The interaction is mediated by a fermionic particle $F$, in which the $νϕ$ scattering cross section characterizes different energy dependent with respect to the kinematic regions, and manifests itself...
Supernova-neutrino-boosted dark matter (SN$\nu$ BDM) has emerged as a promising portal for probing sub-GeV dark matter, offering the distinctive capability of DM mass differentiation via time-of-flight information. In this work, we randomly generate the spatial locations and ages of core-collapse supernovae (CCSNe) in the Milky Way (MW) over the past one hundred thousand years by Monte Carlo...
Axions are hypothetical pseudoscalar particles that have been regarded as promising dark matter (DM) candidates. On the other hand, extended compact objects such as axion stars, which are supported by gravity and axion self interactions, may have also been formed in the early Universe and comprise part of DM. In this work, we consider the lensing of electromagnetic signals from distant sources...
In this work, we calculate the sensitivities on the gauge-boson couplings $g_{aZZ}$, $g_{aZ\gamma}$, and $g_{aWW}$ of an axion-like particle (ALP) that one can achieve at the LHC with $\sqrt{s}=14$ TeV and integrated luminosities of 300 fb$^{-1}$ (current run)
and 3000 fb$^{-1}$ (High-Luminosity LHC). We focus on the associated production processes $pp\to Za \to (l^+l^-)(\gamma\gamma)$ and...
JUNO sensitivity to the annihilation cross section of MeV dark matter (DM) into neutrinos in the galactic halo (A. Abusleme et al. [JUNO], JCAP 09, 001 (2023)) constrains the DM-extended $U(1)_{L_\mu - L_\tau}$ model, characterized by the $Z'$ boson with mass $m_{Z’}$, the coupling $g_{Z’}$ between $Z’$ and the second and third generations of leptons, and the coupling $g_{\chi}$ between...
