A search for periodic AGN variability in Data Release 3
Pablo Huijse, Jordy Davelaar, Joris De Ridder +2
Supermassive black hole binaries (SMBHB) are expected to produce periodic modulations in active galactic nuclei (AGN) light curves, but distinguishing such signals from stochastic…
Plato's view on supermassive black hole binaries: Exploring the faint limit of ESA's Plato space mission
Nicholas Jannsen, Pablo Huijse, Kevin Park +3
The search for supermassive black hole binaries (SMBHBs) has, in recent years, seen the dawn of exploration with several hundred candidates claimed from photometric and spectroscop…
Variability classification of TESS targets in LOPS2, the first long-term pointing field of PLATO. Version 1 of the public variability catalogue
Mykyta Kliapets, Pablo Huijse, Jeroen Audenaert +28
The PLAnetary Transits and Oscillations of stars (PLATO) mission is expected to launch in January 2027. A total of 8\% of its data rate will be dedicated to complementary science t…
The PLATO Science Calibration and Validation Plan: Targets for the First Long-pointing Field
Konstanze Zwintz, Conny Aerts, Andrew Tkachenko +56
In order to meet the science goals of the PLATO space mission, an extensive science calibration and validation plan has been designed. This paper describes this plan, as well as th…
Automated all-sky detection of γ Doradus / δ Scuti hybrids in TESS data from positive unlabelled (PU) learning
Mykyta Kliapets, Pablo Huijse, Andrew Tkachenko +4
The Transiting Exoplanet Survey Satellite (TESS) mission has observed hundreds of millions of stars, substantially contributing to the available pool of high-precision photometric…
The Variable Universe with the Gaia mission and AI methods
L. Eyer, P. Huijse, N. Chornay +5
The Gaia mission has observed over 2 billion stars repeatedly across the entire sky over 10 years, revealing the many astronomical objects that vary on human timescales from second…
