The Atacama Cosmology Telescope: Release of A databaSe of millimeTeR ObservatioNs of Asteroids Using acT (ASTRONAUT)
Ricco C. Venterea, John Orlowski-Scherer, Nicholas Battaglia +7
We present A databaSe of millimeTeR ObservatioNs of Asteroids Using acT (ASTRONAUT) hosted on Amazon Web Services, Inc. (AWS) in the form of a public Amazon Simple Storage Service…
Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…
Detection and characterisation of submm transient sources with a large single-dish telescope
Mike Peel, Dave Clements, Tony Mroczkowski +1
The exploration of the time-variable astronomical sky at submm wavelengths is rapidly becoming more feasible with large sky surveys by Cosmic Microwave Background telescopes with t…
The Simons Observatory: Development of a Pipeline to Detect Rapid Transients in Time-Ordered Data
Justin Clancy, Carlo Bacciagalupi, Josh Borrow +13
We introduce a method for detecting astrophysical transients evolving on timescales of milliseconds to minutes using cosmic microwave background (CMB) survey telescopes. While prev…
Atacama Cosmology Telescope: Observations of supermassive black hole binary candidates. Strong sinusoidal variations at 95, 147 and 225 GHz in PKS 2131021 and PKS J08050111
Adam D. Hincks, Xiaoyi Ma, Przemek Mróz +23
Large sinusoidal variations in the radio light curves of the blazars PKS J08050111 and PKS 2131021 have recently been discovered with an 18-year monitoring programme at the O…
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…
