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…
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…
Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short Wavelength Observation of Solar Analogs
Dan Lubin, Carl Melis, David Tytler
We have identified a sample of 33 Sun-like stars observed by the {\it International Ultraviolet Explorer (IUE)} with the short wavelength (SW) spectrographs that have ground-based…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
Reverberation Mapping of the Kepler-Field AGN KA1858+4850
Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40
KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
