Accelerating BAO Scale Fitting Using Taylor Series
Matthew Hansen, Alex Krolewski, Zachary Slepian
The Universe is currently undergoing accelerated expansion driven by dark energy. Dark energy's essential nature remains mysterious: one means of revealing it is by measuring the U…
The Integrated Sachs Wolfe effect: unWISE and Planck constraints on Dynamical Dark Energy
Alex Krolewski, Simone Ferraro
CMB photons redshift and blueshift as they move through gravitational potentials while propagating across the Universe. If the potential is not constant in time, the photons wi…
Second Data Release of the COSMOS Lyman-alpha Mapping and Tomographic Observation: The First 3D Maps of the Detailed Cosmic Web at 2.05<z<2.55
Benjamin Horowitz, Khee-Gan Lee, Metin Ata +12
We present the second data release of the COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) Survey conducted with the LRIS spectrograph on the Keck-I telescope. This…
Testing Large-Scale Structure Measurements Against Fisher Matrix Predictions
Setareh Foroozan, Alex Krolewski, Will J. Percival
We compare Baryonic Acoustic Oscillation (BAO) and Redshift Space Distortion (RSD) measurements from recent galaxy surveys with their Fisher matrix based predictions. Measurements…
Cosmological constraints from unWISE and Planck CMB lensing tomography
Alex Krolewski, Simone Ferraro, Martin White
A number of recent, low-redshift, lensing measurements hint at a universe in which the amplitude of lensing is lower than that predicted from the CDM model fit to the data of th…
Constraining the Baryon Abundance with the Kinematic Sunyaev-Zel'dovich Effect: Projected-Field Detection Using Planck, WMAP, and unWISE
Aleksandra Kusiak, Boris Bolliet, Simone Ferraro +2
The kinematic Sunyaev-Zel'dovich (kSZ) effect -- the Doppler boosting of cosmic microwave background (CMB) photons scattering off free electrons with non-zero line-of-sight velocit…
