Several thousand core-collapse supernovae (CCSNe) of different flavors have been
discovered so far. However, identifying their progenitors has remained an outstanding open …

This compilation is the fourth data release from the R-Process Alliance (RPA) search for r-
process-enhanced stars and the second release based on" snapshot" high-resolution (R∼ …

Idealized protoplanetary disk and giant planet formation models have been interpreted to
suggest that a giant planet's atmospheric abundances can be used to infer its formation …

Using six years of spectroscopic monitoring of the luminous quasar HE 0435-4312 (z=
1.2231) with the Southern African Large Telescope, in combination with photometric data …

Motivated by the identification of the blazar TXS 0506+ 056 as the first promising high-
energy neutrino counterpart candidate, we search for additional neutrino blazar candidates …

It has been suggested that β Pic b has a supersolar metallicity and subsolar C/O ratio.
Assuming solar carbon and oxygen abundances for the star β Pic and therefore the planet's …

We present the discovery of the optical afterglow and host galaxy of the Swift short-duration
gamma-ray burst (SGRB) GRB 181123B. Observations with Gemini-North starting≈ 9.1 hr …

We present the monitoring of the active galactic nuclei continuum and Mg ii broad-line
emission for the quasar HE 0413-4031 (z= 1.38) based on the six-year monitoring by the …

The most common definition of gamma-ray binaries is based on their composition and their
energy output: a gamma-ray binary consists of a compact object orbiting a star, with periodic …

Long-duration gamma-ray bursts (GRBs) are almost unequivocally associated with very
energetic, broad-line supernovae of Type Ic-BL. While the gamma-ray emission is emitted in …
