28 de may. de 2024 · Dainotti and her teams have harnessed the power of AI to delve into the enigmatic world of gamma-ray bursts (GRBs) – the most luminous and violent explosions in the universe. By leveraging machine learning models, they have achieved unprecedented precision in measuring the distances of these cosmic behemoths. This breakthrough has far ...
22 de may. de 2024 · Gamma-ray method monitors nuclear reactors safely and quickly. Scientists at EPFL have devised and tested out a new, gamma-noise method for monitoring nuclear reactors non-invasively and from a distance. The new method, tested out on EPFL’s CROCUS nuclear reactor, can improve nuclear safety and treaty compliance.
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 ...
21 de may. de 2024 · With great advance of ground-based extensive air shower array, such as LHAASO and HAWC, many very high energy (VHE) gamma-ray sources have been discovered and are been monitored regardless of the day and the night. Hence, the Sun and Moon would have some compact on the observation of gamma-ray sources, which have not been taken into account in previous analysis. In this paper, the influence of ...

17 de may. de 2024 · Ionising radiation, such as gamma rays, X-rays and radioactive particles can cause cancer by damaging DNA. However, how this happens, or how many tumours are caused by radiation damage has not been known. Previous work on cancer had revealed that DNA damage often leaves a molecular fingerprint, known as a mutational signature, on the genome of ...
