Detection of a New GeV Source in the Outer Region of the Coma Cluster: A Signature of External Accretion Shock? by Xiao-Bin Chen, Kai Wang, Yi-Yun Huang, Hai-Ming Zhang, Shao-Qiang Xi, Ruo-Yu Liu, Xiang-Yu Wang

“…The gamma-ray (0.1−10 ^3 GeV) luminosity of the source, 1.4 × 10 ^42 erg s ^−1 , suggests that a fraction  ~10 ^−3 of the kinetic energy flux through the shock surface is transferred to relativistic CR electrons.…”

Constraints on Relativistic Jets from the Fast X-Ray Transient 210423 Using Prompt Radio Follow-up Observations by Dina Ibrahimzade, R. Margutti, J. S. Bright, P. Blanchard, K. Paterson, D. Lin, H. Sears, A. Polzin, I. Andreoni, G. Schroeder, K. D. Alexander, E. Berger, D. L. Coppejans, A. Hajela, J. Irwin, T. Laskar, B. D. Metzger, J. C. Rastinejad, L. Rhodes

“…Considering a wide range of possible redshifts z ≤ 3.5, circumstellar medium density n = 10 ^−6 –10 ^−1 cm ^−3 , and isotropic-equivalent jet kinetic energy E _k _,iso = 10 ^48 –10 ^55 erg, we find that we can rule out wide jets with opening angle θ _j = 15° viewed within 10° off-axis. …”

Identifying Critical Input Parameters for Improving Drag‐Based CME Arrival Time Predictions by C. Kay, M. L. Mays, C. Verbeke

“…We consider CMEs of different strengths from average to extreme size, speed, and mass (kinetic energies between 9×1029 and 6×1032 erg). For each scale CME, we vary the input parameters to reflect the current observational uncertainty in each and determine how accurately each must be known to achieve predictions that are accurate within 5 hr. …”
