Title: Time Domain Imaging of Archetypical Galaxies

Abstract: We propose a time-domain campaign of 10 night equivalent observing run to detect and characterize transient and variable astrophysical phenomena in the galaxies M83 and Cen-A. One of our goals is to acquire a knowledge base of frequently occurring variable phenomena associated with external galaxies in order to be able to recognize them in the LSST future real-time alerts, so that we can efficiently filter such alert streams to identify rare and unusual events. Another primary goal is the study of fast novae, whose hitherto largely unconstrained rates are intrinsically interesting in the context of possible supernova Ia progenitors and for constraining the white dwarf mass function in novae. We have demonstrated the ability to accurately estimate a survey's incompleteness, which will allow us to study the statistics of fast novae and other variable and transient populations. We propose an observing cadence that will probe variability on short time-scales of up to a month, which is also optimal for detecting the novae. It will examine the feasibility of a future multi-semester campaign for probing longer time-scale events.
