Signatures of photon and axion-like particle mixing in the gamma-ray burst jet [PDF]
, 2011 Photons couple to Axion-Like Particles (ALPs) or more generally to any pseudo Nambu-Goldstone boson in the presence of an external electromagnetic field.

Wildlife Biology, EarlyView.Black grouse Lyrurus tetrix declines continue throughout much of temperate Europe, following habitat loss and population isolation, associated with reduced productivity. In northern England, only 1437 lekking males remained in 2014, genetically isolated from other UK populations, and typified by low productivity but high adult survival.

Effective field theories of axion, ALP and dark photon
Journal of High Energy PhysicsAbstract With the help of Young tensor technique, we enumerate the complete and independent set of effective operators up to dim-8 for the extension of the standard model with a Goldstone boson by further imposing the Adler’s zero condition in the soft momentum limit.

The experimental challenge of detecting solar axion-like particles to test the cosmological ALP-photon oscillation hypotheses [PDF]
Astroparticle Physics, 2011 We consider possible experimental tests of recent hypotheses suggesting that TeV photons survive the pair production interaction with extragalactic background light over cosmological distances by converting to axion-like particles (ALPs) in galactic magnetic fields. We show that proposed giant ultra-low background scintillation detectors will even have

Wildlife Biology, EarlyView.After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Looking for dark matter on the light side
, 2014 Among the prominent low-mass dark matter candidates is the QCD axion but also other light and weakly interacting particles beyond the Standard Model. We review briefly the case for such dark matter and give an overview on most recent experimental efforts

Duration of Classicality of Homogeneous Condensates with Attractive Interactions [PDF]
, 2017 Dark matter axions and other highly degenerate bosonic fluids are commonly described by classical field equations. In a recent paper \cite{BECprop} we calculated the duration of classicality of homogeneous condensates with attractive contact interactions
