“…The All-Sky Survey observations with eROSITA and complementary optical surveys will considerably extend the existing bounds in the next decade. The superb soft sensitivity (effective area of 367.9 cm 2 at 1.49 keV), wide-area coverage, and moderate spectral resolution will make probes of particle dark matter the survey uniquely suited for searches for weak X-ray lines and spectral distortions due to ultralight axions photon conversion both in the Milky Way observations and through stacking method of the X-ray emission from other dark matter-dominated objects [228][229][230][231].…”

This white paper discusses the current landscape and prospects for experiments sensitive to particle dark matter processes producing photons and cosmic rays. Much of the γ-ray sky remains unexplored on a level of sensitivity that would enable the discovery of a dark matter signal. Currently operating GeV-TeV observatories, such as Fermi-LAT, atmospheric Cherenkov telescopes, and water Cherenkov detector arrays continue to target several promising dark matter-rich environments within and beyond the Galaxy. Soon, several new experiments will continue to explore, with increased sensitivity, especially extended targets in the sky. This paper reviews the several near-term and longer-term plans for γray observatories, from MeV energies up to hundreds of TeV. Similarly, the X-ray sky has been and continues to be monitored by decade-old observatories. Upcoming telescopes will further bolster searches and allow new discovery space for lines from, e.g., sterile neutrinos and axion-photon conversion.Furthermore, this overview discusses currently operating cosmic-ray probes and the landscape of future experiments that will clarify existing persistent anomalies in cosmic radiation and spearhead possible new discoveries.Finally, the article closes with a discussion of necessary cross section measurements that need to be conducted at colliders to reduce substantial uncertainties in interpreting photon and cosmic-ray measurements in space.Snowmass2021 Cosmic Frontier: The landscape of cosmic-ray and high-energy photon probes of particle dark matter Snowmass2021 Cosmic Frontier: The landscape of cosmic-ray and high-energy photon probes of particle dark matter

“…The high efficiency of ART-XC for conducting X-ray surveys, in particular its ability to cover the whole sky, opens up a new opportunity for searching for X-ray lines from sterile neutrino, a candidate constituent of dark matter. The prospects of the SRG mission in searches for keV-scale mass sterile neutrino dark matter radiatively decaying into active neutrinos and photons have been recently investigated by Barinov et al (2020). It was demonstrated that ART-XC data acquired in the energy range from 5 to 20 keV could provide more stringent constraints compared to those obtained with NuSTAR (Neronov et al 2016;Perez et al 2017;Ng et al 2019;Roach et al 2020).…”

ART-XC (Astronomical Roentgen Telescope -X-ray Concentrator) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory is the flagship astrophysical mission of the Russian Federal Space Program, which was successively launched into orbit around the second Lagrangian point (L2) of the Earth-Sun system with a Proton rocket from the Baikonur cosmodrome on 13 July 2019. The ART-XC telescope will provide the first ever true imaging all-sky survey performed with grazing incidence optics in the 4-30 keV energy band and will obtain the deepest and sharpest map of the sky in the energy range of 4-12 keV. Observations performed during the early calibration and performance verification phase as well as during the on-going all-sky survey that started on 12 Dec. 2019 have demonstrated that the in-flight characteristics of the ART-XC telescope are very close to expectations based on the results of ground calibrations. Upon completion of its 4-year all-sky survey, ART-XC is expected to detect ∼ 5000 sources (∼ 3000 active galactic nuclei, including heavily obscured ones, several hundred clusters of galaxies, ∼ 1000 cataclysmic variables and other Galactic sources), and to provide a high-quality map of the Galactic background emission in the 4-12 keV energy band. ART-XC is also well suited for discovering transient X-ray sources. In this paper, we describe the telescope, results of its ground calibrations, major aspects of the mission, the in-flight performance of ART-XC and first scientific results.
