A piezoelectric-driven glass capillary launcher enables localized, high-efficiency (up to 93%) in-vacuum loading of silica spheres, nanodiamonds, and plate-like particles into single-beam, dual-beam, and standing-wave optical traps.

Stellar gravitational heating reduces dark matter spike overdensities by 2-4 orders of magnitude and drives the inner slope to γ_χ ≈ 1.5 within a few Gyrs, remaining above NFW cusps.
DAMPE independently detects the Fermi bubbles at 26 sigma and the Galactic center GeV excess at 7 sigma, with the excess spectrum and morphology matching Fermi-LAT and fitting a 50 GeV dark matter particle annihilating to b quarks.
Light fermionic dark matter admixed with neutron stars can produce supermassive dark objects whose maximum mass scales as approximately 0.627 times (GeV over m_D) squared solar masses, potentially explaining Sgr A* without a black hole.
ANTARES Galactic Ridge neutrino measurements can constrain annihilating and decaying dark matter for various masses and profiles while comparing to astrophysical backgrounds, with forecasts for future observatories.
Forecasts indicate CSST can detect wide binaries in Segue 1 down to fb ~ 0.01 with 2300 stars but needs 6000 stars and fb ~ 0.1 to distinguish cusped from cored dark matter profiles.
Dark matter halo parameters amplify the scale of closed timelike orbits in Schwarzschild spacetime, inducing phase lags in gravitational waves while light curves retain distinguishable peaks for certain orbital features.
Derivative test on SPARC galaxies shows outer rotation curves are consistent with flat profiles rather than Keplerian taper.
Analysis of an unidentified Fermi gamma-ray source shows inconclusive results with a mild spectral preference for dark matter annihilation over a pulsar origin.
