Long Gamma-Ray Bursts and Type Ic Core Collapse Supernovae Have Similar Locations in Hosts
When the afterglow fades at the site of a long-duration gamma-ray burst (LGRB), Type Ic supernovae (SN Ic) are the only type of core collapse supernova observed. Recent work found that a sample of LGRB in high-redshift galaxies had different environments

Oxychlorine Species on Mars: A Review
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Carbon Monoxide in the Type Ic Supernova 2000ew [PDF]
Abstract We present $K$-band (1.9–2.5$\,{\mu \mathrm {m}}$) spectra of the Type Ic SN 2000ew observed with IRCS on the Subaru Telescope. These data show the first detection of carbon monoxide (CO) emission in a Type Ic supernova. The detection of CO in SN 2000ew provides further evidence that molecule formation may be a common occurrence

Dramatic Rebrightening of the Type-changing Stripped-envelope Supernova SN 2023aew
Multipeaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility.

The properties of SN Ib/c locations [PDF]
Aims: To gain better insight on the physics of stripped-envelope core-collapse supernovae through studying their environments. Methods: We obtained low-resolution optical spectroscopy with the New Technology Telescope (+ EFOSC2) at the locations of 20 ...

SN 1998bw and Other Hyperenergetic Type Ic Supernovae [PDF]
SummaryThe properties of the best-observed peculiar, SN 1998bw-like Type Ic supernovae (sometimes called “hypernovae” ) are reviewed, starting from SN 1998bw itself and including SNe 1997ef and 2002ap. Analysis of the light curves and the spectra shows that, while these SNe display a range of properties (kinetic energy, mass of the ejecta, mass of 56Ni

During the investigation of the reactivity of three Mn complexes, Mn(ClO4)2 shows higher reactivity toward styrene epoxidation, indicating that ligand coordination inhibits the reactivity of the manganese center. Raman spectroscopy provides mechanistic insight: monitoring alkene epoxidation and consumption of the oxidant over time, the true nature of ...

Collapse of Rotating Massive Stars Leading to Black Hole Formation and Energetic Supernovae
We explore a possible explosion scenario resulting from core collapses of rotating massive stars that leave a black hole by performing radiation-viscous-hydrodynamics simulations in numerical relativity.

An optical supernova associated with the X-ray flash XRF 060218
Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae that are more luminous than average and that eject material at very high velocities.
