The Atacama Cosmology Telescope: A demonstration of CMB lensing measurement from daytime data
Irene Abril-Cabezas, Frank J. Qu, Joshua Kim +30
We present a cosmic microwave background (CMB) lensing power spectrum analysis using daytime data (11am-11pm UTC) gathered by the Atacama Cosmology Telescope (ACT) over the period…
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 Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial -modes
Yiqi Liu, Susanna Azzoni, Susan E. Clark +14
We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, , in the context of the Simons Observatory, using a cross-spectrum component…
A Search for Millimeter-Bright Blazars as Astrophysical Neutrino Sources
R. Abbasi, M. Ackermann, J. Adams +424
The powerful jets of blazars have been historically considered as likely sites of high-energy cosmic-ray acceleration. However, particulars of the launched jet and the locations of…
Impact of Galactic non-Gaussian foregrounds on CMB lensing measurements
Irene Abril-Cabezas, Frank J. Qu, Blake D. Sherwin +7
Weak gravitational lensing of the CMB has been established as a robust and powerful observable for precision cosmology. However, the impact of Galactic foregrounds, which has been…
