Abstract GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate veracity this statement by comparing it with a half century prompt gamma-ray burst observations. This is ever detected measures peak flux and fluence. Unexpectedly, highest isotropic-equivalent total energy identified, while luminosity at ∼99th percentile known distribution. explore how such can be powered discuss potential implications for ultralong high-redshift bursts. By geometric extrapolation...
ABSTRACT During the present winter Prof. S. J. Hickson kindly gave me an opportunity of examining1 material from Jamaica in which he discovered female Medusas Millepora (‘99). The results my inquiry are mainly concerned with manner symbiotic zooxauthellæ, found to exist free ova that genus, infect germ cells. I also wish record occurrence male medusai amongst meduste collected above locality, and make some remarks upon oogenesis.
Radiation damage of J-series silicon photomultipliers (SiPMs) has been studied in the context using these photodetectors future space-borne scintillation detectors. Several SiPM samples were exposed to 101.4 MeV protons, with 1 neutron equivalent fluence ranging from 1.27×108 neq/cm2 1.23×1010 neq/cm2. After irradiation, SiPMs experienced a large increase dark current and noise, which may pose problems for long-running space missions terms power consumption, thermal control detection...
