Cosmological Results from the RAISIN Survey: Using Type Ia Supernovae in the Near Infrared as a Novel Path to Measure the Dark Energy Equation of State

D. O. Jones, K. S. Mandel, R. P. Kirshner +26

Type Ia supernovae (SNe Ia) are more precise standardizable candles when measured in the near-infrared (NIR) than in the optical. With this motivation, from 2012-2017 we embarked o…

A Hierarchical Bayesian SED Model for Type Ia Supernovae in the Optical to Near-Infrared

Kaisey S. Mandel, Stephen Thorp, Gautham Narayan +2

While conventional Type Ia supernova (SN Ia) cosmology analyses rely primarily on rest-frame optical light curves to determine distances, SNe Ia are excellent standard candles in n…

Improved Constraints on Anisotropic Birefringent Lorentz Invariance and CPT Violation from Broadband Optical Polarimetry of High Redshift Galaxies

Andrew S. Friedman, Roman Gerasimov, Fabian Kislat +4

In the framework of the Standard Model Extension (SME), we present improved constraints on anisotropic Lorentz invariance and Charge-Parity-Time (CPT) violation by searching for as…

Standard-Model Extension Constraints on Lorentz and CPT Violation From Optical Polarimetry of Active Galactic Nuclei

Andrew S. Friedman, David Leon, Roman Gerasimov +9

Vacuum birefringence from Lorentz and CPT violation in the Standard-Model Extension can be constrained using ground-based optical polarimetry of extragalactic sources. We describe…

Type Ia Supernovae are Excellent Standard Candles in the Near-Infrared

Arturo Avelino, Andrew S. Friedman, Kaisey S. Mandel +3

We analyze a set of 89 Type Ia supernovae (SN Ia) that have both optical and near-infrared (NIR) photometry to derive distances and construct low redshift () Hubble diagr…

Constraints on Lorentz Invariance and CPT Violation using Optical Photometry and Polarimetry of Active Galaxies BL Lacertae and S5 B0716+714

Andrew S. Friedman, David Leon, Kevin D. Crowley +5

Various quantum gravity approaches that extend beyond the standard model predict Lorentz Invariance and Charge-Parity-Time Violation at energies approaching the Planck scale. These…
