We investigate the previous microlensing data collected by the KMTNet survey in search of anomalous events for which no precise interpretations of the anomalies have been suggested. From this investigation, we find that the anomaly in the lensing lig

Transiting Exoplanet Yields for the Roman Galactic Bulge Time Domain Survey Predicted from Pixel-Level Simulations

Autor: Wilson, Robert F., Barclay, Thomas, Powell, Brian P., Schlieder, Joshua, Hedges, Christina, Montet, Benjamin T., Quintana, Elisa, McDonald, Iain, Penny, Matthew T., Espinoza, Nestor, Kerins, Eamonn

The Nancy Grace Roman Space Telescope (Roman) is NASA's next astrophysics flagship mission, expected to launch in late 2026. As one of Roman's core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric and
