Description
Time-domain astrophysics is rapidly expanding into the millimeter and submillimeter regime, opening a largely unexplored window on compact objects and fast transients. In this context, the planned Atacama Large Aperture Submillimeter Telescope (AtLAST) will provide a powerful new platform to study the transient and high-energy Universe at these wavelengths. This talk will review key time-domain science cases at (sub)millimeter wavelengths, focusing on pulsars, magnetars, and Fast Radio Bursts, where detections of high-frequency emission are key to probing emission physics and reducing propagation effects. Building on current results, we will discuss how AtLAST can play a major role in this field through its large field of view and sensitivity. We will also outline the critical instrumental and operational requirements (particularly wideband receivers and high-time-resolution backends) needed to fully exploit this new discovery space.
