The Atacama Cosmology Telescope: Machine Learning Driven Tools for Detecting Millimeter Sources in Timestream Pre-processing
Simran K. Nerval, Erika Hornecker, Yilun Guan +14
We present a new pipeline utilizing machine learning for classifying short-duration features in raw time-ordered data (TOD) of cosmic microwave background survey observations. The…
New Identifications and Multi-wavelength Properties of Extragalactic Fermi Gamma-Ray Sources in the SPT-SZ Survey Field
Lizhong Zhang, Joaquin D. Vieira, Marco Ajello +5
The fourth Fermi Large Area Telescope (LAT) catalog (4FGL) contains 5064 -ray sources detected at high significance, but 26% of them still lack associations at other wavelength…
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…
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: DR6 Power Spectra, Likelihoods and CDM Parameters
Thibaut Louis, Adrien La Posta, Zachary Atkins +165
We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Tele…
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…
The Atacama Cosmology Telescope: Systematic Transient Search of Single Observation Maps
Emily K. Biermann, Yaqiong Li, Sigurd Naess +24
We conduct a systematic search for astrophysical transients using data from the Atacama Cosmology Telescope (ACT). The data were taken from 2017 to 2022 in three frequency bands sp…
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…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…

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…
Optical Characterization of the SPT-3G Focal Plane
Zhaodi Pan, Peter Ade, Zeeshan Ahmed +73
The third-generation South Pole Telescope camera is designed to measure the cosmic microwave background across three frequency bands (95, 150 and 220 GHz) with ~16,000 transition-e…
The Optical Design of CHARIS: An Exoplanet IFS for the Subaru Telescope
Mary Anne Peters-Limbach, Tyler D. Groff, N. Jeremy Kasdin +15
