The Atacama Cosmology Telescope: DR6 Constraints on Isotropic Time-Dependent Cosmic Birefringence from Axion-like Particles
Zachary B. Huber, Huajian Yang, Steve K. Choi +7
Axion-like particles (ALPs) with sufficiently low masses are dark matter candidates because they could account for much or all of the observed dark matter energy density and help e…
The Atacama Cosmology Telescope: Constraints on the anisotropic screening and birefringence effects with DR6
Darby M. Kramer, Alexander van Engelen, Frank J. Qu +14
While we have learned much from recent surveys of the mm-wave sky, many secondary anisotropies of the CMB remain under-explored. We consider two of these here: the anisotropic scre…

Time-dependent deflection reconstruction: new technique to search for gravitational waves with the cosmic microwave background
Alvin Leluc, Joel Meyers, Alexander van Engelen
Gravitational waves (GWs) passing through the Earth cause a correlated pattern of time-dependent deflections of the apparent position of astronomical sources. We build upon standar…
