Systematic Study of Gamma-ray bright Blazars with Optical Polarization and Gamma-ray Variability
Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa +18
Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence f…
Altitudinal dependence of meteor radio afterglows measured via optical counterparts
K. S. Obenberger, J. M. Holmes, J. D. Dowell +4
Utilizing the all-sky imaging capabilities of the LWA1 radio telescope along with a host of all-sky optical cameras, we have now observed 44 optical meteor counterparts to radio af…
A Low Frequency Survey of Giant Pulses from the Crab Pulsar
T. Eftekhari, K. Stovall, J. Dowell +2
We present a large survey of giant pulses from the Crab Pulsar as observed with the first station of the Long Wavelength Array. Automated methods for detecting giant pulses at low…
Rates, Flux Densities, and Spectral Indices of Meteor Radio Afterglows
K. S. Obenberger, J. D. Dowell, P. J. Hancock +4
Using the narrowband all-sky imager mode of the LWA1 we have now detected 30 transients at 25.6 MHz, 1 at 34 MHz, and 93 at 38.0 MHz. While we have only optically confirmed that 37…
Bayesian constraints on the global 21-cm signal from the Cosmic Dawn
G. Bernardi, J. T. L. Zwart, D. Price +7
The birth of the first luminous sources and the ensuing epoch of reionization are best studied via the redshifted 21-cm emission line, the signature of the first two imprinting the…
Polarization angle swings in blazars: The case of 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +61
Over the past few years, several occasions of large, continuous rotations of the electric vector position angle (EVPA) of linearly polarized optical emission from blazars have been…
