We investigate the thermal photon production from constant magnetic field ina strongly coupled and anisotropic plasma via the gauge/gravity duality. Thedual geometry with pressure anisotropy is generated from the axion-dilatongravity action introduced by Mateos and Trancancelli and the magnetic field iscoupled to fundamental matters(quarks) through the D3/D7 embeddings. We findthat the photon spectra with different quark mass are enhanced at largefrequency when the photons are emitted parallel to the anisotropic directionwith larger pressure or perpendicular to the magnetic field. However, in theopposite conditions for the emitted directions, the spectra approximatelysaturate isotropic results in the absence of magnetic field. On the other hand,a resonance emerges at moderate frequency for the photon spectrum with heavyquarks when the photons move perpendicular to the magnetic field. The resonanceis more robust when the photons are polarized along the magnetic field. On thecontrary, in the presence of pressure anisotropy, the resonance will besuppressed. There exist competing effects of magnetic field and pressureanisotropy on meson melting in the strongly coupled super Yang-Mills plasma,while we argue that the suppression led by anisotropy may not be applied to thequark gluon plasma.
