The Atacama Cosmology Telescope: A census of bridges between galaxy clusters
G. Isopi, V. Capalbo, A. D. Hincks +27
According to CMB measurements, baryonic matter constitutes about of the mass-energy density of the universe. A significant population of these baryons, for a long time referr…
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…
AtLAST Science Overview Report
Mark Booth, Pamela Klaassen, Claudia Cicone +81
Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current…
The RAdio Galaxy Environment Reference Survey (RAGERS): Evidence of an anisotropic distribution of submillimeter galaxies in the 4C 23.56 protocluster at z=2.48
Dazhi Zhou, Thomas R. Greve, Bitten Gullberg +41
High-redshift radio(-loud) galaxies (HRGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification. Howe…
CCAT: Prime-Cam Optics Overview and Status Update
Zachary B. Huber, Lawrence T. Lin, Eve M. Vavagiakis +17
Prime-Cam is a first-generation science instrument for the CCAT Observatory's six-meter aperture Fred Young Submillimeter Telescope (FYST). FYST's crossed-Dragone design provides h…
The Simons Observatory: Dark Characterization of the Large Aperture Telescope
Saianeesh K. Haridas, Zeeshan Ahmed, Tanay Bhandarkar +20
The Simons Observatory (SO) is a cosmic microwave background experiment composed of three 0.42 m Small Aperture Telescopes (SATs) and one 6 m Large Aperture Telescope (LAT) in the…
The Atacama Cosmology Telescope DR6 and DESI: Structure formation over cosmic time with a measurement of the cross-correlation of CMB Lensing and Luminous Red Galaxies
Joshua Kim, Noah Sailer, Mathew S. Madhavacheril +70
We present a high-significance cross-correlation of CMB lensing maps from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) with spectroscopically calibrated luminous red…
Drone-Based Antenna Beam Calibration in the High Arctic
Lawrence Herman, Christopher Barbarie, Will Tyndall +17
Precision calibration is a critical requirement for future ultra-low-frequency observations of the early universe. The Array of Long Baseline Antennas for Taking Radio Observations…
The Simons Observatory: Studies of Detector Yield and Readout Noise From the First Large-Scale Deployment of Microwave Multiplexing at the Large Aperture Telescope
Thomas P. Satterthwaite, Zeeshan Ahmed, Kyuyoung Bae +21
The Simons Observatory is a new ground-based cosmic microwave background experiment, which is currently being commissioned in Chile's Atacama Desert. During its survey, the observa…
The key science drivers for the Atacama Large Aperture Submillimeter Telescope (AtLAST)
Mark Booth, Pamela Klaassen, Claudia Cicone +14
Sub-mm and mm wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current single-dish fac…
Atacama Large Aperture Submillimeter Telescope \mbox{(AtLAST)} Science: Probing the Transient and Time-variable Sky
John Orlowski-Scherer, Thomas J. Maccarone, Joe Bright +25
The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary…
Sensitive 3mm Imaging of Discrete Sources in the Fields of tSZ-Selected Galaxy Clusters
Simon R. Dicker, Karen Perez Sarmiento, Brian Mason +12
In this paper we present the results of a blind survey for compact sources in 243 Galaxy clusters that were identified using the thermal Sunyaev-Zeldovich effect (tSZ). The survey…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Solar and stellar observations
Sven Wedemeyer, Miroslav Barta, Roman Brajsa +35
Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composit…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Resolving the Hot and Ionized Universe through the Sunyaev-Zeldovich effect
Luca Di Mascolo, Yvette Perrott, Tony Mroczkowski +23
An omnipresent feature of the multi-phase ``cosmic web'' is that warm/hot (> K) ionized gas pervades it. This gas constitutes a relevant contribution to the overall universal…
maria: A novel simulator for forecasting (sub-)mm observations
J. van Marrewijk, T. W. Morris, T. Mroczkowski +8
Millimeter-wave single-dish telescopes offer two key advantages compared to interferometers: they can efficiently map larger portions of the sky, and they can recover larger spatia…
