Burrage, Davis, and Shaw recently suggested exploiting the correlations between high and low energy luminosities of astrophysical objects to probe possible mixing between photons and axionlike particles (ALP) in magnetic field regions. They also presented evidence for the existence of ALP's by analyzing the optical/UV and x-ray monochromatic luminosities of active galactic nuclei. We extend their work by using the monochromatic luminosities of 320 unobscured active galactic nuclei from the… Expand
Axion-like particles: possible hints and constraints from the high-energy Universe
The high-energy Universe is potentially a great laboratory for searching new light bosons such as axion-like particles (ALPs). Cosmic sources are indeed the scene of violent phenomena that involveExpand
Indirect and direct search for dark matter
The majority of the matter in the universe is still unidentified and under investigation by both direct and indirect means. Many experiments searching for the recoil of dark-matter particles offExpand
Extragalactic photon-ALP conversion at CTA energies
Magnetic fields in extragalactic space between galaxy clusters may induce conversions between photons and axion-like particles (ALPs), thereby shielding the photons from absorption on theExpand
Physics potential of the International Axion Observatory (IAXO)
We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particles (ALPs) with aExpand
Towards a new generation axion helioscope
We study the feasibility of a new generation axion helioscope, the most ambitious and promising detector of solar axions to date. We show that large improvements in magnetic field volume, x-rayExpand
Energetic axion-like particle production in galaxies
Relativistic axion-like particles (ALPs) originating from the stellar interiors, along with the ones coming from photon-ALP mixing in the galactic magnetic fields, contribute together to make anExpand
Interdisciplinary Aspects of High-Energy Astrophysics
Modern astrophysics, especially at GeV energy scales and above is a typical example where several disciplines meet: the location and distribution of the sources is the domain of astronomy. AtExpand
The effective Lagrangian of dark energy from observations
Using observational data on the expansion rate of the universe (H(z)) we constrain the effective Lagrangian of the current accelerated expansion. Our results show that the effective potential isExpand
The Intrinsic Bispectrum of the Cosmic Microwave Background
Cosmology, intended as the study of the origin and evolution of the Universe and its components, has advanced from being a philosophical discipline to a data-driven science. Much of this progress wasExpand
Tension in the Void: Cosmic Rulers Strain Inhomogeneous Cosmologies
New constraints on inhomogeneous Lemaȋtre-Tolman-Bondi (LTB) models alternative to Dark Energy are presented, focusing on adiabatic profiles with space-independent Big Bang and baryon fraction. TheExpand
