the case for x ray transients
The Case for X-ray Transients
  • What are the most compelling science cases for current and future X-ray transient studies?
  • What efforts does the X-ray transient community need to undertake to best lobby for the importance of X-ray transient studies (past and present) to the general astronomical community?
resource utilization
Resource Utilization
  • How will new planned or soon to be launched instruments support X-ray transient surveys?
  • What inventive ways can we develop to utilize new instruments that may not be originally designed for X-ray transient studies?
  • What steps do we need to take to transition from the era of RXTE to the era without it?
  • What important lessons have we learned from RXTE?
multiwavelength coordination
Multiwavelength Coordination
  • How do we best coordinate multi-wavelength observations, especially for X-ray transient surveys?
  • Do we need to develop an X-ray Transient Network or are existing infrastructures like The Gamma-ray Circular Network and the Astronomers Telegram sufficient?
  • What cadences are needed to achieve various science priorities at different wavelengths?
  • Are there opportunities for citizen science with X-ray transient surveys?
