abstract

We present a new analysis of the diffuse soft $\gamma$-ray emission towards the inner Galaxy as measured by the SPectrometer aboard the INTEGRAL satellite (SPI) with 16 years of data taking. The analysis implements a spatial template fit of SPI data and an improved instrumental background model. We characterize the contribution of Primordial Black Holes (PBH) as dark matter (DM) candidates evaporating into $\mathcal{O}$(1) MeV photons by including, for the first time, the spatial distribution of their signal into the fitting procedure. No PBH signal is detected, and we set the strongest limit on PBH DM for masses up to $4 \times 10^{17}$ g, significantly closing in into the so-called asteroid mass range.

  1. Primordial Black Hole from Tensor-induced Density Fluctuation: First-order Phase Transitions and Domain Walls

    astro-ph.CO 2026-05 unverdicted novelty 6.0 of 10

    Tensor perturbations from FOPT and domain-wall sources are claimed to induce second-order scalar perturbations large enough to form primordial black holes, potentially all of the dark matter.

  2. Relaxation of Energy Constraints for Positrons Generating the Galactic Annihilation Signal

    astro-ph.HE 2025-06 conditional novelty 6.0 of 10

    A full forward model of INTEGRAL, COMPTEL, and EGRET data relaxes the upper limit on positron injection energy for the Galactic 511 keV signal from a few MeV to roughly 40-60 MeV.

  3. Neutrino lines and photon continua from cascade dark matter decay

    hep-ph 2026-07 conditional novelty 5.0 of 10

    In cascade dark-matter decay, neutrino-line searches can beat gamma-ray limits whenever the intermediate mediator is long-lived enough to suppress the photon flux.

  4. Constraining primordial black holes and primordial curvature power spectrum with extragalactic muon neutrino

    astro-ph.CO 2026-07 conditional novelty 4.0 of 10

    Neutrino flux from WIMP annihilation in PBH-seeded UCMHs yields f_PBH ≲ 4×10^{-5} (strongest) and P_R ≲ 10^{-1.65} at k∼3×10^{12} Mpc^{-1}.
