Eternal inflation bubble collision signature on CMB remote dipole and quadrupole fields

Hongbo Cai, Pengjie Zhang, Yilun Guan

The remote dipole and quadrupole fields (RDF/RQF) encode information about the observable universe as seen from remote places within our past light cone. Sensitive to the superhori…

Atacama Cosmology Telescope: Constraints on the Millimetre Flux of the Crab Pulsar

Yilun Guan, Sigurd Naess, Ian Niebres +8

Millimeter-wave observations of pulsars, while crucial for understanding their emission mechanisms, remain scarce. We demonstrate that high-precision cosmic microwave background (C…

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.…

The Atacama Cosmology Telescope: Large-scale velocity reconstruction with the kinematic Sunyaev--Zel'dovich effect and DESI LRGs

Fiona McCarthy, Nicholas Battaglia, Rachel Bean +27

The kinematic Sunyaev--Zel'dovich (kSZ) effect induces a non-zero density-density-temperature bispectrum, which we can use to reconstruct the large-scale velocity field from a comb…

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…

The Atacama Cosmology Telescope: Reionization kSZ trispectrum methodology and limits

Niall MacCrann, Frank J. Qu, Toshiya Namikawa +20

Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight mo…

The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky

William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151

Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…

The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth

Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155

We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…

The Bias to Cosmic Microwave Background Lensing Reconstruction from the Kinematic Sunyaev-Zel'dovich Effect at Reionization

Hongbo Cai, Mathew S. Madhavacheril, J. Colin Hill +1

The power spectrum of reconstructed cosmic microwave background (CMB) lensing maps is a powerful tool for constraints on cosmological parameters like the sum of the neutrino masses…
