The Effect of Pulsar Geometry on the Observed Gamma-ray Spectrum of Millisecond Pulsars
Sheridan J. Lloyd, Paula M. Chadwick, Anthony M. Brown
We analyse 13 yrs of -LAT PASS 8 events from 127 gamma-ray emitting millisecond pulsars (MSPs) in the energy range 0.1100 GeV and significantly detect 118 MSPs.…
Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation
The Cherenkov Telescope Array Consortium, :, H. Abdalla +496
The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…
Axion Constraints from Quiescent Soft Gamma-ray Emission from Magnetars
Sheridan J. Lloyd, Paula M. Chadwick, Anthony M. Brown +2
Axion-like-particles (ALPs) emitted from the core of a magnetar can convert to photons in its magnetosphere. The resulting photon flux is sensitive to the product of the ALP-…
Reply to a comment on `Understanding the gamma-ray emission from the globular cluster 47 Tuc: evidence for dark matter?'
Anthony M. Brown, Thomas Lacroix, Sheridan Lloyd +2
Analysing 9 years of Fermi-LAT observations, we recently studied the spectral properties of the prominent globular cluster 47 Tuc (Brown et al. 2018). In particular, we investigate…
Constraining Axion Mass through Gamma-ray Observations of Pulsars
Sheridan J. Lloyd, Paula M. Chadwick, Anthony M. Brown
We analyze 9 years of PASS 8 -LAT data in the 60500 MeV range and determine flux upper limits (UL) for 17 gamma-ray dark pulsars as a probe of axions produced by…
Gamma-ray emission from high Galactic latitude globular clusters
Sheridan J. Lloyd, Paula M. Chadwick, Anthony M. Brown
We analyse 8 years of PASS 8 Fermi-LAT data, in the 60 MeV - 300 GeV energy range, from 30 high Galactic latitude globular clusters. Six of these globular clusters are detected wit…
Understanding the -ray emission from the globular cluster 47 Tuc: evidence for dark matter?
Anthony M. Brown, Thomas Lacroix, Sheridan Lloyd +2
47 Tuc was the first globular cluster observed to be -ray bright, with the -rays being attributed to a population of unresolved millisecond pulsars (MSPs). Recent kinematic d…
