Hace 11 horas · Generally, machine learning methods exploit various characteristics of sensors signals in the value, time, frequency, and time–frequency domain. In this work, the convolutional neural network (CNN) VGG-16 is applied for analysis of histogram images of signals obtained for water–air flow by using gamma-ray absorption.
Hace 1 día · Previously, Xing et al. has reported likely detection of extended γ 𝛾 \gamma italic_γ-ray emission from RCW 103 in the 1–300 GeV data obtained with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi).At the time, only 5 years of the Fermi-LAT data were collected and the source model for the data analysis was based on the Fermi-LAT second source catalog ...
Hace 1 día · 3rd June 2024. Gamma ray bursts are highly energetic explosions which have been observed at remote cosmic distances from us. Here are some facts about asteroids and gamma ray bursts. They are by far the most powerful and brightest electromagnetic events known to happen in the Universe. Bursts can last up to ten seconds to ten minutes.
Hace 1 día · We analyze more than 15 years of the \\gr\\ data, obtained with the Large Area Telescope (LAT) onboard {\\it the Fermi Gamma-ray Space Telescope (Fermi)}, for the region of the young supernova remnant (SNR) RCW~103, since the nearby source 4FGL J1616.2$-$5054e, counterpart to HESS~J1616$-$518 and $\\simeq$13\\,arcmin away from the SNR, is determined to be extended in the more recent Fermi-LAT ...
Hace 3 días · Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime.
Hace 2 días · Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.A material containing unstable nuclei is considered radioactive.Three of the most common types of decay are alpha, beta, and gamma decay.The weak force is the mechanism that is responsible for beta ...
