The Atacama Cosmology Telescope: Mitigating the impact of extragalactic foregrounds for the DR6 CMB lensing analysis
Niall MacCrann, Blake D. Sherwin, Frank J. Qu +47
We investigate the impact and mitigation of extragalactic foregrounds for the CMB lensing power spectrum analysis of Atacama Cosmology Telescope (ACT) data release 6 (DR6) data. Tw…
Simultaneous Millimeter-wave, Gamma-ray, and Optical Monitoring of the Blazar PKS 2326-502 During a Flaring State
J. C. Hood, A. Simpson, A. McDaniel +66
Including millimeter-wave (mm-wave) data in multi-wavelength studies of the variability of active galactic nuclei (AGN) can provide insights into AGN physics that are not easily ac…
Sidelobe Modeling and Mitigation for a Three Mirror Anastigmat Cosmic Microwave Background Telescope
Ian Gullett, Bradford Benson, Robert Besuner +16
Telescopes measuring cosmic microwave background (CMB) polarization on large angular scales require exquisite control of systematic errors to ensure the fidelity of the cosmologica…
The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements
Christina D. Kreisch, Minsu Park, Erminia Calabrese +21
We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works,…
Simons Observatory: Broadband Metamaterial Anti-Reflection Cuttings for Large Aperture Alumina Optics
Joseph E. Golec, Shreya Sutariya, Rebecca Jackson +7
We present the design, fabrication, and measured performance of metamaterial Anti-Reflection Cuttings (ARCs) for large-format alumina filters operating over more than an octave of…
The Atacama Cosmology Telescope: Measurement and Analysis of 1D Beams for DR4
Marius Lungu, Emilie R. Storer, Matthew Hasselfield +28
We describe the measurement and treatment of the telescope beams for the Atacama Cosmology Telescope's fourth data release, DR4. Observations of Uranus are used to measure the cent…
