TL;DR: The Carnegie Supernova Project-II (CSP-II) was an NSF-funded, four-year program to obtain optical and near-infrared observations of a "Cosmology" sample of ∼100 Type Ia supernovae located in the smooth Hubble flow as discussed by the authors.
Journal ArticleDOI
Radioactively-Powered Rising Lightcurves of Type Ia Supernovae
TL;DR: In this paper, the authors explore what range of power-law increases are possible due to the presence of radioactive material near the surface of the exploding white dwarf and summarize what constraints such a model places on the structure of the progenitor and the distribution of ejecta.
Journal ArticleDOI
The Dispersion and Rotation Measure of Supernova Remnants and Magnetized Stellar Winds: Application to Fast Radio Bursts
Anthony L. Piro,Bryan Gaensler +1 more
TL;DR: In this paper, the authors summarize the scalings for the dispersion measure and rotation measure in the case of a constant density ambient medium and of a progenitor stellar wind, finding that the amount of ionized material is controlled by the dynamics of the reverse shock.
Journal ArticleDOI

TL;DR: In this paper, the authors present and analyse a new TDE, AT2017eqx at redshift z = 0.1089, discovered by Pan-STARRS and ATLAS, and show that the position of the transient is consistent with the nucleus of its host galaxy; it peaks at a luminosity of $L \approx 10^{44}$ erg s$^{-1}$; and the spectrum shows a persistent blackbody temperature with broad H I and He II emission.
