Figure 1: Variables in the Local Group dwarf galaxy IC 1613

The HCV catalogue contains many groups with deep observations obtained over multiple visits, making them appropriate for long-term variability studies of active galactic nuclei (AGN), from the most luminous point-like quasars to low-luminosity AGN. The HCV catalogue contains 179 multi-filter variable candidates in the five CANDELS fields (GOODS South, GOODS North, COSMOS, EGS, and UDS).

This image shows three example light curves of variable sources in the CANDELS fields that are classified via spectroscopy as AGN — HCV light curves of : a quasar in GOODS-North (upper panel), a Seyfert-1 in GOODS-South (middle panel), and a new variable AGN in EGS (lower panel).
