Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023
O. Vince, C. M. Raiteri, M. Villata +72
(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
Radio frequency interference identification using eigenvalue decomposition for multi-beam observations
Juntao Bai, Shi Dai, Na Wang +10
With the installation of next-generation phased array feed (PAF) receivers on radio telescopes, there is an urgent need to develop effective and computationally efficient radio fre…
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…
VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
Frequency- and phase-resolved polarimetry of millisecond pulsars and its application to timing
Małgorzata Curyło, Andrew Zic, Shuangqiang Wang +16
Pulsar timing is used for a variety of applications including tests of fundamental physics, probing the structure of neutron stars, and detecting nanohertz gravitational waves. Dev…
