Cosmic topology. Part I. Limits on orientable Euclidean manifolds from circle searches
Pip Petersen, Yashar Akrami, Craig J. Copi +9
The Einstein field equations of general relativity constrain the local curvature at every point in spacetime, but say nothing about the global topology of the Universe. Cosmic micr…
Cosmic topology. Part IIIa. Microwave background parity violation without parity-violating microphysics
Amirhossein Samandar, Javier Carrón Duque, Craig J. Copi +11
The standard cosmological model, which assumes statistical isotropy and parity invariance, predicts the absence of correlations between even-parity and odd-parity observables of th…
The Atacama Cosmology Telescope: A measurement of galaxy cluster temperatures through relativistic corrections to the thermal Sunyaev-Zeldovich effect
William R. Coulton, Adriaan J. Duivenvoorden, Zachary Atkins +32
The high electron temperature in galaxy clusters (keV or K) leads to corrections at the level of a few percent in their thermal Sunyaev-Zeldovich effect signatures.…
Efficient estimation of rotation-induced bias to reconstructed CMB lensing power spectrum
Hongbo Cai, Yilun Guan, Toshiya Namikawa +1
The cosmic microwave background (CMB) lensing power spectrum is a powerful probe of the late-time universe, encoding valuable information about cosmological parameters such as the…
Cosmic topology. Part IVa. Classification of manifolds using machine learning: a case study with small toroidal universes
Andrius Tamosiunas, Fernando Cornet-Gomez, Yashar Akrami +16
Non-trivial spatial topology of the Universe may give rise to potentially measurable signatures in the cosmic microwave background. We explore different machine learning approaches…
The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters
Mathew S. Madhavacheril, Frank J. Qu, Blake D. Sherwin +156
We present cosmological constraints from a gravitational lensing mass map covering 9400 sq. deg. reconstructed from CMB measurements made by the Atacama Cosmology Telescope (ACT) f…
