The Nancy Grace Roman Space Telescope Wide Field Instrument: Characterization of the Brighter-Fatter Effect in a Roman H4RG-10 Detector using the Talbot Effect
Jennie Paine, Ami Choi, Christopher Merchant +14
The Nancy Grace Roman Space Telescope will conduct several community-driven surveys using its Wide Field Instrument (WFI), which contains 18 Teledyne H4RG-10 near-infrared detector…
The Atacama Cosmology Telescope: DR6 Maps
Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
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…
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…
Cross-correlation of Luminous Red Galaxies with ML-selected AGN in HSC-SSP: Unobscured AGN residing in more massive halos
Rodrigo Córdova Rosado, Andy D. Goulding, Jenny E. Greene +7
Active galactic nuclei (AGN) are the signposts of black hole growth, and likely play an important role in galaxy evolution. An outstanding question is whether AGN of different spec…
Cosmological limits on the neutrino mass sum for beyond-CDM models
Helen Shao, Jahmour J. Givans, Jo Dunkley +4
The sum of cosmic neutrino masses can be measured cosmologically, as the sub-eV particles behave as `hot' dark matter whose main effect is to suppress the clustering of matter comp…
Hints of tensions in the cosmic microwave background temperature and polarization quadrupoles
Jahmour J. Givans, Marc Kamionkowski
The large-angular-scale falloff in the autocorrelation function for the cosmic microwave background (CMB) temperature has long intrigued cosmologists and fueled speculation about s…
The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky
William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151
Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…
The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters
Mathew S. Madhavacheril, Frank J. Qu, Blake D. Sherwin +156
We present cosmological constraints from a gravitational lensing mass map covering 9400 sq. deg. reconstructed from CMB measurements made by the Atacama Cosmology Telescope (ACT) f…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing
Masaya Yamamoto, Katherine Laliotis, Emily Macbeth +16
One challenge for applying current weak lensing analysis tools to the Nancy Grace Roman Space Telescope is that individual images will be undersampled. Our companion paper presente…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: I. Simulation methodology and general results
Christopher M. Hirata, Masaya Yamamoto, Katherine Laliotis +16
The upcoming Nancy Grace Roman Space Telescope will carry out a wide-area survey in the near infrared. A key science objective is the measurement of cosmic structure via weak gravi…
A Joint Roman Space Telescope and Rubin Observatory Synthetic Wide-Field Imaging Survey
M. A. Troxel, C. Lin, A. Park +22
We present and validate 20 deg of overlapping synthetic imaging surveys representing the full depth of the Nancy Grace Roman Space Telescope High-Latitude Imaging Survey (HLIS)…
Non-linearities in the Lyman- forest and in its cross-correlation with dark matter halos
Jahmour J. Givans, Andreu Font-Ribera, Anže Slosar +6
Three-dimensional correlations of the Lyman- (Ly) forest and cross correlations between the Ly forest and quasars have been measured on large scales, allowing a precise me…
Quantum yield and charge diffusion in the Nancy Grace Roman Space Telescope infrared detectors
Jahmour J. Givans, Ami Choi, Anna Porredon +6
The shear signal required for weak lensing analyses is small, so any detector-level effects which distort astronomical images can contaminate the inferred shear. The Nancy Grace Ro…
Streaming Velocity Effects on the Post-reionization 21 cm Baryon Acoustic Oscillation Signal
Heyang Long, Jahmour J. Givans, Christopher M. Hirata
The relative velocity between baryons and dark matter in the early Universe can suppress the formation of small-scale baryonic structure and leave an imprint on the baryon acoustic…
Brighter-fatter effect in near-infrared detectors -- III. Fourier-domain treatment of flat field correlations and application to WFIRST
Jenna K. C. Freudenburg, Jahmour J. Givans, Ami Choi +8
Weak gravitational lensing has emerged as a leading probe of the growth of cosmic structure. However, the shear signal is very small and accurate measurement depends critically on…
Redshift-space streaming velocity effects on the Lyman- forest baryon acoustic oscillation scale
Jahmour J. Givans, Christopher M. Hirata
The baryon acoustic oscillation (BAO) scale acts as a standard ruler for measuring cosmological distances and has therefore emerged as a leading probe of cosmic expansion history.…
