Semi-parametric $\gamma$-ray modeling with Gaussian processes and variational inference

  title={Semi-parametric \$\gamma\$-ray modeling with Gaussian processes and variational inference},
  author={Siddharth Mishra-Sharma and Kyle Cranmer},
  journal={arXiv: High Energy Astrophysical Phenomena},
Mismodeling the uncertain, diffuse emission of Galactic origin can seriously bias the characterization of astrophysical gamma-ray data, particularly in the region of the Inner Milky Way where such emission can make up over 80% of the photon counts observed at ~GeV energies. We introduce a novel class of methods that use Gaussian processes and variational inference to build flexible background and signal models for gamma-ray analyses with the goal of enabling a more robust interpretation of the…

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection
A closer look at CP-violating Higgs portal dark matter as a candidate for the GCE
A statistically significant excess of gamma rays has been reported and robustly confirmed in the Galactic Center over the past decade. Large local dark matter densities suggest that this Galactic


Analyzing γ rays of the Galactic Center with deep learning
We present a new method to interpret the $\gamma$-ray data of our inner Galaxy as measured by the Fermi Large Area Telescope (Fermi LAT). We train and test convolutional neural networks with
Background model systematics for the Fermi GeV excess
The possible gamma-ray excess in the inner Galaxy and the Galactic center (GC) suggested by Fermi-LAT observations has triggered a large number of studies. It has been interpreted as a variety of
SkyFACT: High-dimensional modeling of gamma-ray emission with adaptive templates and penalized likelihoods
We present SkyFACT (Sky Factorization with Adaptive Constrained Templates), a new approach for studying, modeling and decomposing diffuse gamma-ray emission. Like most previous analyses, the approach
Evidence for Unresolved γ-Ray Point Sources in the Inner Galaxy.
A new method to characterize unresolved point sources (PSs) generalizing traditional template fits to account for non-Poissonian photon statistics is presented, and it is found that PSs account for ∼50% of the total extragalactic γ-ray background in the energy range ∼1.9 to 11.9 GeV.
The characterization of the gamma-ray signal from the central Milky Way: A case for annihilating dark matter
Abstract Past studies have identified a spatially extended excess of ∼1–3 GeV gamma rays from the region surrounding the Galactic Center, consistent with the emission expected from annihilating dark
Strong evidence that the galactic bulge is shining in gamma rays
There is growing evidence that the Galactic Center Excess identified in the $\textit{Fermi}$-LAT gamma-ray data arises from a population of faint astrophysical sources. We provide compelling
An analytic relation between the statistics of photons in pixels and the number counts of multi-photon point sources is used to constrain the distribution of gamma-ray point sources below the Fermi
Strong Support for the Millisecond Pulsar Origin of the Galactic Center GeV Excess.
It is argued that other extragalactic or Galactic sources, a mismodeling of Galactic diffuse emission, or the thick-disk population of pulsars are unlikely to account for this observation of clear excess emission in the Inner Galaxy.
Possible Evidence For Dark Matter Annihilation In The Inner Milky Way From The Fermi Gamma Ray Space Telescope
We study the gamma rays observed by the Fermi Gamma Ray Space Telescope from the direction of the Galactic Center and find that their angular distribution and energy spectrum are well described by a
Distinguishing Dark Matter from Unresolved Point Sources in the Inner Galaxy with Photon Statistics
Data from the Fermi Large Area Telescope suggests that there is an extended excess of GeV gamma-ray photons in the Inner Galaxy. Identifying potential astrophysical sources that contribute to this
