A Comparative Study of TESS Light Curve Extraction Methods Applied to Blazars

Autor: Poore, Ethan, Carini, Michael, Dingler, Ryne, Wehrle, Ann E., Wiita, Paul J.

Blazars are characterized by largely aperiodic variability on timescales ranging from minutes to decades across the electromagnetic spectrum. The TESS (Transiting Exoplanet Survey Satellite) mission provides continuous sampling of blazar variability

A flare from the TeV blazar Mrk 421, occurring in March 2010, was observed for 13 consecutive days from radio to very high energy (VHE, E > 100 GeV) gamma-rays with MAGIC, VERITAS, Whipple, FermiLAT, MAXI, RXTE, Swift, GASP-WEBT, and several optical

We have used photometry from the Kepler satellite to characterize the variability of four radio-loud active galactic nuclei (AGN) on timescales from years to minutes. The Kepler satellite produced nearly continuous high precision data sets which prov

We analyze the multifrequency behavior of the quasar 3C 454.3 during three prominent \gamma-ray outbursts: 2009 Autumn, 2010 Spring, and 2010 Autumn. The data reveal a repeating pattern, including a triple flare structure, in the properties of each \

Kepler Photometry of Four Radio-Loud AGN in 2010-2012

Autor: Wehrle, Ann E., Wiita, Paul J., Unwin, Stephen C., Di Lorenzo, Paolo, Revalski, Mitchell, Silano, Daniel, Sprague, Dan

We have used Kepler photometry to characterize variability in four radio-loud active galactic nuclei (three quasars and one object tentatively identified as a Seyfert 1.5 galaxy) on timescales from minutes to months, comparable to the light crossing
