The purpose of line-intensity mapping (IM), an emerging tool for extragalactic astronomy and
cosmology, is to measure the integrated emission along the line of sight from spectral lines …

A number of extensions of the Standard Model predict the existence of new light, weakly
coupled particles that couple to the visible sector through higher-dimensional operators …

In the era of gravitational wave (GW) detection from astrophysical sources by LIGO/VIRGO, it
is of great importance to take the quantum gravity effect of graviton-photon (GRAPH) mixing …

Inelastic dark matter (iDM) is an interesting thermal DM scenario that can pose challenges
for conventional detection methods. However, recent studies demonstrated that iDM coupled …

We propose a mechanism generating primordial magnetic fields after the e+ e-annihilations.
Our mechanism involves an ultralight axionlike particle (ALP) which constitutes the dark …

The dark axion portal is a dimension-5 coupling between an axion-like particle (ALP), a
photon, and a dark photon, which is one of the targets of the intensity frontier searches …

Generation of cosmic microwave background (CMB) elliptic polarization due to the Cotton–
Mouton (CM) effect in a cosmic magnetic field is studied. We concentrate on the generation …

We investigate graviton-photon oscillations sourced by cosmological magnetic fields from
Gertsenshtein effect. We adopt a robust perturbative approach and we find that the …

Dark axion portal connects an axion-like-particle (ALP), which can be the QCD axion, with
the SM by the coupling to a photon and a dark photon, leading to a rich and distinct …

We present the extended electrodynamics in the presence of the axion and dark photon. We
derive the extended versions of Maxwell's equations and dark Maxwell's equations (for both …
