LISA, the Laser Interferometer Space Antenna, due to launch mid-2035, is a large class space mission by the European Space Agency (ESA). In partnership with NASA and ESA-member sta…
Probable Quasi-Periodic Oscillations in the {\tt TESS} observations of blazars in the Swift X-ray Survey
Ashutosh Tripathi, Paul J. Wiita, Krista Lynne Smith
This work presents possible quasi-periodic oscillations in the Transiting Exoplanet Survey Satellite observations of blazars that are in the 157-month hard X-ray survey done by Swi…
Application of time-series analysis methods to a multiple-sector TESS observations: the case of the radio-loud blazar 3C 371
Ashutosh Tripathi, Paul J. Wiita, Ryne Dingler +4
We present various time series analysis methods to analyze multiple-sector observations of bright AGN from the Transiting Exoplanet Survey Satellite (TESS) and examine whether issu…
Revisiting radio variability of the blazar 3C 454.3
Ashutosh Tripathi, Alok C. Gupta, Krista Lynne Smith +7
We examine lengthy radio light curves of the flat spectrum radio galaxy 3C 454.3 for possible quasi-periodic oscillations (QPOs). The data used in this work were collected at five…
