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…
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…
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.…
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: 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…
