The double-peaked Type Ic supernova 2019cad: another SN 2005bf-like object
(Oxford University Press, 2021-04)
We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first ∼100 d from explosion. Based on the light-curve morphology, we find that SN 2019cad resembles the double-peaked Type Ib/c ...
Luminous Type II supernovae for their low expansion velocities
(Oxford University Press, 2020-05)
We present optical and near-infrared data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of early interaction of the ejecta with ...
Extending the variability selection of active galactic nuclei in the W-CDF-S and SERVS/SWIRE region
(EDP Sciences, 2020-02)
Context. Variability has proven to be a powerful tool to detect active galactic nuclei (AGN) in multi-epoch surveys. The new-generation facilities expected to become operational in the next few years will mark a new era ...
