High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
Light curve modeling of the nearest neutron star candidate LAMOST J235456.73+335625.9
Qing-bo Han, Mouyuan Sun, Zhi-Xiang Zhang +1
The discovery of heavy radioactive elements (e.g., ) on Earth suggests that supernova explosions may have occurred near our planet within the past million years,…
Absence of Radio Emission Reveals an Exceptionally Weak Explosion of the Putative Historical Supernova Pa 30
Yi-xuan Shao, Ping Zhou, Xiao Zhang +7
We present the first deep radio continuum observations of Pa 30, a nebula hosting a unique optical source driven by an ultrafast outflow with a velocity of 16,000 km s. The…
Cosmic ray neutrons in magnetized astrophysical structures
Ellis R. Owen, Yoshiyuki Inoue, Tatsuki Fujiwara +2
Cosmic rays are often modeled as charged particles. This allows their non-ballistic propagation in magnetized structures to be captured. In certain situations, a neutral cosmic ray…
