The Galactic Center Excess (GCE) is an extended gamma-ray source in the central region of the Galaxy found in Fermi Large Area Telescope data. In recent years it has become apparent that the GCE may not be spherically symmetric, but may be spatially correlated with the distribution of stellar mass in the Galactic bulge, potentially favoring an unresolved population of millisecond pulsars (MSPs) scenario. In this thesis, we perform detailed modelling of the Galactic MSP population. Including in… Expand

Millisecond pulsar interpretation of the Galactic center gamma-ray excess
• Physics
• 2014
It was found in the Fermi-LAT data that there is an extended $\gamma$-ray excess in the Galactic center region. The proposed sources to be responsible for the excess include the dark matterExpand

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 compellingExpand
On Detecting Millisecond Pulsars at the Galactic Center
• Physics

The lack of detected pulsars at the Galactic Center (GC) region is a long-standing mystery. We argue that the high stellar density in the central parsec around the GC is likely to result in a pulsarExpand

Analyses of Fermi Gamma-Ray Space Telescope data have revealed a source of excess diffuse gamma rays towards the Galactic center that extends up to roughly $\pm$20 degrees in latitude. The leadingExpand
Dark matter and pulsar model constraints from Galactic Center Fermi-LAT gamma-ray observations

Employing Fermi-LAT gamma ray observations, several independent groups have found excess extended gamma ray emission at the Galactic center (GC). Both, annihilating dark matter (DM) or a populationExpand
Radio detection prospects for a bulge population of millisecond pulsars as suggested by fermi-lat observations of the inner galaxy
• Physics

Analogously to globular clusters, the dense stellar environment of the Galactic center has been proposed to host a large population of as-yet undetected millisecond pulsars (MSPs). Recently, thisExpand
Strong Support for the Millisecond Pulsar Origin of the Galactic Center GeV Excess.
• Physics, Medicine
• Physical review letters
• 2016
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. Expand
Millisecond pulsars and the Galactic Center gamma-ray excess: the importance of luminosity function and secondary emission

Several groups of authors have analyzed Fermi LAT data in a region around the Galactic Center finding an unaccounted gamma-ray excess over diffuse backgrounds in the GeV energy range. It has beenExpand
Contribution of cosmic rays interacting with molecular clouds to the Galactic Center gamma-ray excess

The Fermi-LAT data appear to have an excess of gamma-rays from the inner 150 pc of the Galactic Center. The main explanations proposed for this are an unresolved population of millisecond pulsarsExpand
