Discovery and Extensive Follow-up of SN 2024ggi, a Nearby Type IIP Supernova in NGC 3621
The Astrophysical JournalWe present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 ± 0.3 Mpc. The SN was caught $5.{8}_{-2.9}^{+1.9}$ hr after its explosion by the ATLAS survey.Ting-Wan Chen, Sheng Yang, Shubham Srivastav, Takashi J. Moriya, Stephen J.

, 2010 We discuss the impact of strange hadrons, in particular hyperons, on the
gross features of compact stars and on core-collapse supernovae. Hyperons are
likely to be the first exotic species which appears around twice normal nuclear

, 2006 The cosmic stellar birth rate can be measured by standard astronomical
techniques. It can also be probed via the cosmic stellar death rate, though
until recently, this was much less precise.Ahn, Ando, Ando, Beacom, Bionta, Bisnovatyi-Kogan, Clayton, Fukugita, Hirata, Hopkins, John F.
