A strategy for LSST to unveil a population of kilonovae without gravitational-wave triggers

Igor Andreoni, Shreya Anand, Federica B. Bianco +10

We present a cadence optimization strategy to unveil a large population of kilonovae using optical imaging alone. These transients are generated during binary neutron star and pote…

Presto-Color: A Photometric Survey Cadence for Explosive Physics & Fast Transients

Federica B. Bianco, Maria R. Drout, Melissa L. Graham +6

We identify minimal observing cadence requirements that enable photometric astronomical surveys to detect and recognize fast and explosive transients and fast transient features. O…

Portable Adaptive Optics for Exoplanet Imaging

Yongtian Zhu, Jiangpei Dou, Xi Zhang +3

The Portable Adaptive Optics (PAO) is a low-cost and compact system, designed for 4-meter class telescopes that have no Adaptive Optics (AO), because of the physical space limitati…
