Roman Conference Poster Small


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.)

Abstract submission has been extended! We are still accepting abstracts for contributed talks, in-person posters, and e-posters (for virtual participants). Please select from the Type pulldown menu whether the abstract is for a talk or a poster. Abstracts can be submitted here. (You will first need to sign in; or, if you have never attended an IPAC-hosted conference before, sign up, create a profile, and then sign in.) "Creating" the abstract is equivalent to submitting it. Contributed talks will be 12 min, with an additional 3 min for Q&A.

Extended deadline for abstracts through December 8, 2021.

Registration is now open! You can register for the conference here. Again, please first sign in, or, if you have never attended an IPAC-hosted conference before, sign up and create a profile. You will then be able to access the Registration page. Registration for both in-person and virtual attendance will be free. The registration deadline is January 14, 2022.

We are currently going forward at this time with a hybrid conference as originally planned. However, please NOTE: Caltech, as of October 18, 2021, has limited access to indoor campus spaces to individuals with proof of full COVID-19 vaccination. This policy affects campus visitors and therefore impacts on conference attendees. Registrants for in-person attendance must be prepared to provide proof of full vaccination. Furthermore, following current campus policy on occupancy of the conference venue, we will need to limit in-person total attendance at 75. In-person registration will therefore be on a first-come, first-served basis, until this limit is reached. Additionally, the use of face coverings indoors is currently mandated. This, of course, has no impact on participants registering for virutal attendance. Should health and safety conditions worsen in the weeks prior to the conference and further restrictions be imposed by Caltech, the Pasadena Public Health Department, and Los Angeles County, we will announce a decision no later than December 20, 2021 whether we will need to switch to a fully-virtual conference.
