The high-energy modular array (HEMA) is one of three instruments that compose the Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays (STROBE-X) mission concept. The HEMA is a large-area, high-throughput non-imaging pointed instrument based on the large area detector (LAD) developed as part of the Large Observatory For X-ray Timing (LOFT) mission concept. It is designed for spectral timing measurements of a broad range of sources and provides a transformative increase in sensitivity to X-rays in the energy range of 2 to 30 keV compared with previous instruments, with an effective area of 3.4 m2 at 8.5 keV and an energy resolution of better than 300 at 6 keV in its nominal field of regard.
We give an overview of the science objectives and mission design of the “Spectroscopic Time-Resolving Observatory for Broadband Energy X-rays” observatory, which has been proposed as a NASA probe-class (∼$1.5B) mission in response to the Astro2020 recommendation for an X-ray probe.
The Spectroscopic Time-Resolving Observatory for Broadband X-rays (STROBE-X) is a proposed NASA Astrophysics Probe-class mission. STROBE-X is a time domain and multi-messenger mission designed to provide an unparalleled laboratory for probing strong gravity and the behavior of matter in extreme environments. The instrument suite encompasses a wide-field monitor and two pointed instruments to provide transient discovery and the capability for rapid follow-up with broadband (0.2–30 keV), high time resolution spectroscopy. Over 10,000 pointed observations will be conducted each year and STROBE-X will be able to slew to targets within minutes in response to transients triggered by on-board or ground alerts. Here, we present an overview of the STROBE-X science drivers, mission design, and instrument complement.
SCORPIO (Spectrograph and Camera for the Observation of Rapid Phenomena in the Infrared and Optical) is a multiband instrument covering 0.385um to 2.35um in spectroscopy and 0.400um to 2.35um in imaging, currently under development for the Gemini Observatory. The instrument is intended to be deployed as a facility instrument at Gemini South in Chile to enable detailed follow-up observations of transients detected by the Vera C. Rubin Observatory. The instrument is designed with eight parallel channels corresponding to the standard g, r, i, z, Y, J, H, and Ks passbands. Here we present an update on the status of the instrument, the data reduction software, and the current path forward to completion.
SCORPIO is the next facility instrument for the Gemini South telescope at Cerro Pachon, Chile. SCORPIO’s main science driver is the detection and monitoring of faint time-domain events, in particular the follow-up of discoveries by the Vera C. Rubin Observatory, but it can also carry out with unique efficiency a large variety of astrophysical programs. The instrument has recently passed Critical Design Review and is now in its Assembly, Integration and Verification phase. In this paper we provide an updated overview of the final instrument design and the main performance parameters in light of the science drivers.
