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…
Constraints on axions from patchy screening of the cosmic microwave background
Samuel Goldstein, Fiona McCarthy, Cristina Mondino +3
The resonant conversion of cosmic microwave background (CMB) photons into axions within large-scale structure induces an anisotropic spectral distortion in CMB temperature maps. Ap…
Dark photon limits from patchy dark screening of the cosmic microwave background
Fiona McCarthy, Dalila Pirvu, J. Colin Hill +3
Dark photons that kinetically mix with the Standard Model photon give rise to new spectral anisotropies (patchy dark screening) in the cosmic microwave background (CMB) due to conv…
Large-scale galactic-dust-cleaned cosmic infrared background maps from \textit{Planck} PR4 and HI4PI with \texttt{pyilc}
Fiona McCarthy
The cosmic infrared background (CIB) traces star-forming galaxies throughout cosmic history, with emission peaking at . CIB anisotropies are present at the far-infrared f…
Signal-preserving CMB component separation with machine learning
Fiona McCarthy, J. Colin Hill, William R. Coulton +1
Analysis of microwave sky signals, such as the cosmic microwave background, often requires component separation with multi-frequency methods, where different signals are isolated b…
Constraints on Dark Matter-Dark Energy Scattering from ACT DR6 CMB Lensing
Alex Laguë, Fiona McCarthy, Mathew Madhavacheril +2
The predicted present-day amplitude of matter fluctuations based on cosmic microwave background (CMB) anisotropy data has sometimes been found discrepant with more direct measureme…
The Atacama Cosmology Telescope: A search for late-time anisotropic screening of the Cosmic Microwave Background
William R. Coulton, Theo Schutt, Abhishek S. Maniyar +37
Since the formation of the first stars, most of the gas in the Universe has been ionized. Spatial variations in the density of this ionized gas generate cosmic microwave background…
