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…

A tale of tails: Dark matter interpretations of the Fermi GeV excess in light of background model systematics
Several groups have identified an extended excess of gamma rays over the modeled foreground and background emissions towards the Galactic center (GC) based on observations with the Fermi Large Area…

CMB bounds on disk-accreting massive primordial black holes
Stellar-mass primordial black holes (PBH) have been recently reconsidered as a dark matter (DM) candidate after the aLIGO discovery of several binary black hole (BH) mergers with masses of tens of…

Fundamental physics with the Square Kilometre Array
Abstract The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey…

The Fermi-LAT GeV excess as a tracer of stellar mass in the Galactic bulge
An anomalous emission component at energies of a few gigaelectronvolts and located towards the inner Galaxy is present in the Fermi-LAT data. At present, the two most promising explanations are the…

DIFFUSE γ-RAY EMISSION FROM MISALIGNED ACTIVE GALACTIC NUCLEI
Active galactic nuclei (AGNs) with jets seen at small viewing angles are the most luminous and abundant objects in the γ-ray sky. AGNs with jets misaligned along the line of sight appear fainter in…

RADIO DETECTION PROSPECTS FOR A BULGE POPULATION OF MILLISECOND PULSARS AS SUGGESTED BY FERMI-LAT OBSERVATIONS OF THE INNER GALAXY
The dense stellar environment of the Galactic center has been proposed to host a large population of as-yet undetected millisecond pulsars (MSPs). Recently, this hypothesis has found support in an…

Simulated Milky Way analogues: implications for dark matter direct searches
We study the implications of galaxy formation on dark matter direct detection using high resolution hydrodynamic simulations of Milky Way-like galaxies simulated within the EAGLE and APOSTLE…

Simulated Milky Way analogues: implications for dark matter indirect searches
We study high-resolution hydrodynamic simulations of Milky Way type galaxies obtained within the “Evolution and Assembly of GaLaxies and their Environments” (EAGLE) project, and identify those that…

Searching for Primordial Black Holes in the Radio and X-Ray Sky.
TLDR
It is argued that the accretion of gas onto a population of massive primordial black holes in the Milky Way can be used to identify such a population with more sensitive future radio and x-ray surveys.
