Error mitigation via stabilizer measurement emulation
A. Greene, M. Kjaergaard, M. E. Schwartz +16
Dynamical decoupling (DD) is a widely-used quantum control technique that takes advantage of temporal symmetries in order to partially suppress quantum errors without the need reso…
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…
