The NASA Physics of the Cosmos (PCOS) Program Office is organizing a TDAMM Initiative Workshop. The goal of the 3-day workshop, to be held August 22–24, 2022, in the Annapolis area, is to identify and prioritize the top science questions for Time Domain and Multi-Messenger Astrophysics (TDAMM) that need to be addressed to implement the recommendations of the Astro 2020 Decadal Report. NASA invites US and international members of the ground and space science community and of the astronomy and physics communities to attend the workshop and contribute to its final product, a publicly available report with findings for the NASA Headquarters Astrophysics Division.

This workshop is strictly on science only and we are steering away from proposed missions, focusing instead on current and already approved missions and facilities. NASA needs the science information before we can all start planning for missions. Contributions highlighting proposed missions are not solicited.

Overview:

Rationale

The 2020 Astrophysics Decadal Survey identified TDAMM as the top space priority of the sustaining activities for the future decades, recognizing breakthrough science in the last several years and setting expectations for the future. One of the primary recommendations of the Decadal Survey was to address outstanding science questions, and the need for coordination of the various stakeholders from the ground and space, astronomy, and physics communities. It is first necessary to hone in on the most compelling scientific questions that need to be addressed, and the priority of those questions in order to plan for future activities for technology investments, mission concepts, and infrastructure. To this end, participation of all stakeholders is necessary. The workshop results will assist NASA with next steps for the formulation of a plan for enabling the Astro 2020 recommendation to “sustain the necessary suite of space-based electromagnetic capabilities required to study transient and time-variable phenomena, and to follow-up multi-messenger events.”

Example questions the workshop will address include:

  • What are or will be the most pressing scientific questions for TDAMM in the next several years?
  • Which capabilities (top level) are needed to address them?
  • How well does the current mission fleet address them?
  • Which avenues of inquiry will be most ripe for discovery in the next few years?
  • What collaboration between the ground and space can be done to maximize the science?

Format of the Workshop

The workshop will be conducted in person in the Annapolis, MD, area, with in-person and virtual participation. Speakers should plan to attend in person if possible, but remote presentations will also be arranged when needed.

Agenda

The meeting will be held over 3 full days and will feature plenary sessions and parallel sessions. Every day, there will be up to 4 parallel sessions distributed in the morning and afternoon; at the end of the day, all participants will gather in a plenary session to summarize and discuss the primary findings of the day in their session. On the last day, an outline of the report will be drafted with the final conclusions of the deliberations and writing assignments made.

Parallel sessions:

Non-Terminal Sources:
    WD systems (CVs, WD binaries)
    NS/BH systems (XRBs, magnetars, pulsars)
    SMBH systems (AGN, SMBH binaries)
    supernova remnants, starburst galaxies, galaxy clusters

Jetted Transients:
    NS/BH systems (micro quasars, LGRBs, SGRBs)
    SMBH systems (TDEs, blazers)
    engine-powered SNe

Merger driven Transients:
    WD-WD, WD-NS, WD-BH
    NS-NS, NS-BH, BH-BH
    SMBH binaries, EMRIs
    stellar mergers, common envelope systems, classical and symbiotic novae

Explosive transients:
    Type Ia SNe, WD TDEs
    core-collapse SNe (normal, SLSNe, PISNe, interacting)
    known unknowns (FRBs, FXTs) and unknown unknowns

Contributed Talks and e-Posters

Each parallel session will feature an invited speaker and contributed talks, selected among submitted abstracts. Note that the talks should be focused on addressing the specific questions of the workshop, and not simply be a presentation of original research in the field. Here is the suggested format for the contributed talks.

Posters will only be accepted in an electronic format. Poster should also conform to the provided format; however, early career scientists are allowed to focus more on their research results. The posters will be made available electronically to all attendants one week before the start of the workshop, to give ample time for reviewing.

Information on the Venue

The workshop will be held as a hybrid format, including both in-person and virtual attendance. The in-person will be held at a venue in the Annapolis area. Due to space constraints, it is important that you indicate if you intend to attend in person. If the limit is reached, preference will be given to invited speakers and presenters. If your plans change and you are unable to attend in person, please contact TDAMM-Workshop@bigbang.gsfc.nasa.gov. Your timely update will ensure that those who may be on a waiting list are able to attend.

Due to Federal regulations, NASA is not able to provide refreshments. Therefore, each attendant is expected to be responsible for their meals, snacks, and coffee/tea. While an opening Reception and a Closing Dinner cannot be hosted by NASA, we will identify venues and options for attendants to get together on an individual pay basis.

We will be monitoring local covid status and may make a determination to shift to virtual only attendance.
