We present constraints on the nature of axions and axionlike particles (ALPs) by analyzing gamma-ray data from neutron stars using the Fermi Large Area Telescope. In addition to axions solving the ... 
Searches for Axionlike Particles Using $\gamma$-Ray Observations
Axionlike particles (ALPs) are a common prediction of theories beyond the Standard Model of particle physics that could explain the entirety of the cold dark matter. These particles could be detectedExpand
Searching for spectral oscillations due to photon-axionlike particle conversion using the Fermi-LAT observations of bright supernova remnants
Axionlike particles (ALPs) are one promising type of dark matter candidate particle that may generate detectable effects on gamma-ray spectra other than the canonical weakly interacting massiveExpand
Neutron star cooling via axion emission by nucleon–nucleon axion bremsstrahlung
Neutron stars generally cool off by the emission of $$\gamma $$γ-rays and neutrinos. But axions can also be produced inside a neutron star by the process of nucleon–nucleon axion bremsstrahlung. TheExpand
Constraints on axion-like particle properties with TeV gamma-ray observations of Galactic sources
Axion-like particles (ALPs) can oscillate to photons and vice versa in electromagnetic fields. The photon-ALP oscillation provides an attractive solution to the apparent transparency of the UniverseExpand
Phenomenology and Astrophysics of Gravitationally-Bound Condensates of Axion-Like Particles
Light, spin-0 particles are ubiquitous in theories of physics beyond the Standard Model, and many of these make good candidates for the identity of dark matter. One very well-motivated candidate ofExpand
Axion-Like Particle Searches with IACTs
The growing interest in axion-like particles (ALPs) stems from the fact that they provide successful theoretical explanations of physics phenomena, from the anomaly of the CP-symmetry conservation inExpand
Sensitivity projections for dark matter searches with the Fermi large area telescope
Abstract The nature of dark matter is a longstanding enigma of physics; it may consist of particles beyond the Standard Model that are still elusive to experiments. Among indirect search techniques,Expand
Constraining Axion Mass through Gamma-ray Observations of Pulsars
We analyze 9 years of PASS 8 $\textit{Fermi}$-LAT data in the 60$-$500 MeV range and determine flux upper limits (UL) for 17 gamma-ray dark pulsars as a probe of axions produced by nucleon-nucleonExpand
Indirect Dark Matter Searches: Status and Prospects
I present of summary of the current status of searches for signals from dark matter interactions in astrophysical data. I also discuss the prospects for such searches in the next few years.


A cosmological bound on the invisible axion
Abstract The production of axions in the early universe is studied. Axion models which break the U(1)PQ symmetry above 1012 GeV are found to produce an unacceptably large axion energy density.
Solar neutrino limit on axions and keV-mass bosons
The all-flavor solar neutrino flux measured by the Sudbury Neutrino Observatory constrains nonstandard energy losses to less than about 10% of the Sun's photon luminosity, superseding aExpand
New constraints for heavy axion-like particles from supernovae
We derive new constraints on the coupling of heavy pseudoscalar (axion-like) particles to photons, based on the gamma ray flux expected from the decay of these particles into photons. After beingExpand
Neutrino and axion emissivities of neutron stars from nucleon–nucleon scattering data
Abstract Neutrino and axion production in neutron stars occurs mainly as bremsstrahlung from nucleon–nucleon (NN) scattering. The energy radiated via neutrinos or axions is typically very smallExpand
A new cosmological mass limit on thermal relic axions
Observations of the cosmological large-scale structure provide well- established neutrino mass limits. We extend this argument to thermal relic axions. We calculate the axion thermal freeze-outExpand
Nucleon-nucleon bremsstrahlung of axions and pseudoscalar particles from neutron-star matter

Cosmology of the invisible axion
Abstract We identify a new cosmological problem for models which solve the strong CP puzzle with an invisible axion, unrelated to the domain wall problem. Because the axion is very weakly coupled,Expand

The Not So Harmless Axion
Abstract Cosmological aspects of a very weakly interacting axion are discussed. A solution to the problem of domain walls discussed by Sikivie is mentioned. Demanding that axions do not dominate theExpand
Astrophysical methods to constrain axions and other novel particle phenomena
Various extensions of the standard model of elementary particle interactions predict the existence of new particles such as axions, or “exotic” properties of known particles such as neutrino magneticExpand
