Searching for changing-state AGNs in massive datasets -- I: applying deep learning and anomaly detection techniques to find AGNs with anomalous variability behaviours

P. Sánchez-Sáez, H. Lira, L. Martí +14

The classic classification scheme for Active Galactic Nuclei (AGNs) was recently challenged by the discovery of the so-called changing-state (changing-look) AGNs (CSAGNs). The phys…

Asteroids' Size Distribution and Colors from HiTS

J. Peña, C. Fuentes, F. Förster +8

We report the observations of solar system objects during the 2015 campaign of the High cadence Transient Survey (HiTS). We found 5740 bodies (mostly Main Belt asteroids), 1203 of…

The delay of shock breakout due to circumstellar material seen in most Type II Supernovae

F. Förster, T. J. Moriya, J. C. Maureira +35

Type II supernovae (SNe) originate from the explosion of hydrogen-rich supergiant massive stars. Their first electromagnetic signature is the shock breakout, a short-lived phenomen…

The High Cadence Transient Survey (HITS): Compilation and characterization of light-curve catalogs

Jorge Martínez-Palomera, Francisco Förster, Pavlos Protopapas +12

The High Cadence Transient Survey (HiTS) aims to discover and study transient objects with characteristic timescales between hours and days, such as pulsating, eclipsing and explod…
