Hace 5 días · Gamma rays come from black holes, neutron stars, supernovae (stars exploding at the end of their lives), pulsars, quasars, and other sources we don't understand yet. Great bursts of gamma rays occur frequently, and it's still a mystery where they are coming from.
Hace 5 días · Core collapse supernova explosions are some of the brightest events in the known Universe. After the thermonuclear burning stage, a core of a massive star (\(M>8M_{\odot}\), where \(M_{\odot}\) is the Solar mass) loses its hydrodynamic stability, and within the characteristic time \(\lesssim 1\) second after the catastrophic contraction up to nuclear densities, an enormous amount of energy ...

Hace 4 días · We present photometric and spectroscopic observations of SN 2023fyq, a type Ibn supernova in the nearby galaxy NGC 4388 (D$\\simeq$18~Mpc). In addition, we trace long-standing precursor emission at the position of SN 2023fyq using data from DLT40, ATLAS, ZTF, ASAS-SN, Swift, and amateur astronomer Koichi Itagaki. Precursor activity is observed up to nearly three years before the supernova ...
