Dark Matter Subhalo interpretations using machine learning: The fourth Fermi-LAT catalog

چکیده
The quest for detecting dark-matter subhalos within the Galactic halo has taken many forms. Particularly interesting and promising is use of spectral degeneracies to distinguish otherwise indistinguishable gamma-ray sources with near-null star formation. In further exploration this realm, we attempt classify high-latitude, non-variable, unassociated Pulsar-like spectra in 20-70 GeV Dark Matter annihilation range. Implementing supervised machine learning models on 5788 recorded ten-year Fermi-LAT catalog (4FGL-DR2), where 1667 were formerly unassociated, a total 30 events over galactic latitude 10 degrees, |b| >= mean accuracy 98%. This classification allows us present subset potentially unanticipated as high-confidence Subhalo candidates.

Dark matter subhalos in the Fermi first source catalog
The Milky Way’s dark matter halo is thought to contain large numbers of smaller subhalos. These objects can contain very high densities of dark matter and produce potentially observable fluxes of gamma rays. In this article, we study the gamma ray sources in the Fermi Gamma Ray Space Telescope’s recently published First Source Catalog and attempt to determine whether this catalog might contain ...
متن کاملConstraining Decaying Dark Matter with Fermi LAT Gamma-rays
High energy electrons and positrons from decaying dark matter can produce a significant flux of gamma rays by inverse Compton off low energy photons in the interstellar radiation field. This possibility is inevitably related with the dark matter interpretation of the observed PAMELA and FERMI excesses. The aim of this paper is providing a simple and universal method to constraint dark matter mo...
متن کاملDark Matter Interpretations of the e± Excesses after FERMI
The cosmic-ray excess observed by PAMELA in the positron fraction and by FERMI and HESS in e− + e can be interpreted in terms of DM annihilations or decays into leptonic final states. Final states into τ ’s or 4μ give the best fit to the excess. However, in the annihilation scenario, they are incompatible with photon and neutrino constraints, unless DM has a quasi-constant density profile. Fina...
متن کاملSearch for High-Confidence Blazar Candidates and Their MWL Counterparts in the Fermi-LAT Catalog Using Machine Learning
A large fraction of the gamma-ray sources presented in the Third Fermi-LAT source catalog (3FGL) is affiliated with counterparts and source types, but 1010 sources remain unassociated and 573 sources are associated with active galaxies of uncertain type. The purpose of this study is to assign blazar classes to these unassociated and uncertain sources, and to link counterparts to the unassociate...
متن کاملPerspective of Galactic dark matter subhalo detection on Fermi/GLAST from the EGRET observation
The perspective of detectability of Galactic dark matter subhaloes on the Fermi satellite is investigated in this work. Under the assumptions that dark matter annihilation accounts for the “GeV excess” of the Galactic diffuse γrays discovered by EGRET and the γ-ray flux is dominated by the contribution from subhaloes of dark matter, we calculate the expected number of dark matter subhaloes that...
