Francesca Calore, Christopher Eckner
These lecture notes provide an overview of high-energy astrophysical processes involving axions, axion-like particles (ALPs), and other weakly interacting slim particles (WISPs) fo…
A robust neural determination of the source-count distribution of the Fermi-LAT sky at high latitudes
Christopher Eckner, Noemi Anau Montel, Florian List +2
Over the past 16 years, the Fermi Large Area Telescope (LAT) has significantly advanced our view of the GeV gamma-ray sky, yet several key questions remain - such as the compositio…
Detecting dark matter sub-halos in the Galactic plane with the Cherenkov Telescope Array Observatory
Christopher Eckner, Veronika Vodeb, Tejas Satheesh +4
Numerous observations confirm the existence of dark matter (DM) at astrophysical and cosmological scales. Theory and simulations of galaxy formation predict that DM should cluster…
No evidence for gamma-ray emission from the Sagittarius dwarf spheroidal galaxy
Christopher Eckner, Silvia Manconi, Francesca Calore
More than a decade ago, the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope unveiled the existence of two gigantic gamma-ray lobes known as the Fermi bubbles. While…
Simulation-based inference of radio millisecond pulsars in globular clusters
Joanna Berteaud, Christopher Eckner, Francesca Calore +2
Millisecond pulsars (MSPs) are abundant in globular clusters (GCs), which offer favorable environments for their creation. While the advent of recent, powerful facilities led to a…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
Probing protoneutron stars with gamma-ray axionscopes
Alessandro Lella, Francesca Calore, Pierluca Carenza +4
Axion-like particles (ALPs) coupled to nucleons can be efficiently produced in the interior of protoneutron stars (PNS) during supernova (SN) explosions. If these ALPs are also cou…

Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
Robust inference of the Galactic centre gamma-ray excess spatial properties
Deheng Song, Christopher Eckner, Chris Gordon +6
The gamma-ray Fermi-LAT Galactic centre excess (GCE) has puzzled scientists for over 15 years. Despite ongoing debates about its properties, and especially its spatial distribution…
