TL;DR: The results of a Palomar Transient Factory (PTF) archival search for blue transients that lie in the magnitude range between "normal" corecollapse and superluminous supernovae (i.e., with −21 ≤ M_(R (peak)) ≤ − 19) were presented in this article.

TL;DR: A temporal series of high-resolution optical spectra of the SN Ia PTF 11kx reveals a complex circumstellar environment that provides an unprecedentedly detailed view of the progenitor system.

TL;DR: In this article, high-dispersion observations of the Na I D λλ5890, 5896 and K I 7665, 7699 interstellar lines and the diffuse interstellar band at 5780 A in the spectra of 32 Type Ia supernovae are used as an independent means of probing dust extinction.

TL;DR: It is shown that the velocity structure of absorbing material along the line of sight to 35 type Ia supernovae tends to be blueshifted, and these structures are likely signatures of gas outflows from the supernova progenitor systems.

TL;DR: Perets et al. as discussed by the authors identified three peculiar transients with five distinguishing characteristics: peak luminosity in the gap between novae and supernovae (M_R ≈ - 15.5 to -16.5), rapid photometric evolution (t_(rise) ≈12-15 days), large photospheric velocities (≈6000 to 11,000 km s^(-1)), early spectroscopic evolution into nebular phase (1 to 3 months) and peculiar nebular spectra dominated by Calcium.
