Time-domain astrophysics comprises a vast array of phenomena, that span the range from our own Solar System to high-redshift galaxies, from asteroids and comets to novae, supernovae, active galactic nuclei, and gamma-ray bursts. We are now at the dawn of multi-messenger astrophysics, with the electromagnetic signatures of gravitational-wave sources within our observational grasp, most recently illustrated by the binary neutron-star merger GW170817. The Nancy Grace Roman Space Telescope will be a powerful observatory for exploring the time-varying Universe. Via its core surveys, it will search for supernova explosions at cosmological distances, as well as for the microlensing signatures of planets orbiting stars in our Galaxy. Roman will naturally enable serendipitous discoveries and analyses of many other time-variable phenomena during the course of its mission, through a vigorous investigation program including new surveys. This 3-day conference will bring together inclusively members of the community to discuss the exciting time-domain astrophysics that will be investigated with the Roman Space Telescope.

Themes will include:

• Multi-messenger astrophysics
• Tidal disruption events
• Supernovae
• Cepheids, Miras, and other periodic variables
• Novae and related phenomena
• Massive-star eruptions and outbursts
• Gamma-ray bursts
• Fast radio burst counterparts and hosts
• Active Galactic Nuclei
• Microlensing
• Solar System objects
• Time-domain data mining software and tools
• Alerts and brokers
• Discovery space for new phenomena
• Synergies with other missions and facilities (Rubin, ELTs, Euclid, JWST, etc.)

UPDATE (1/3/22): The LOC has made the decision that, in view of the current swiftly evolving and unpredictable conditions of the COVID-19 pandemic and the impact it is having, particularly on Caltech campus policies, we will be conducting this conference as a fully virtual event. Any previous in-person registrations were automatically converted to virtual.
