Gamma-ray bursts (GRBs) are divided into two populations,; long GRBs that derive from the
core collapse of massive stars (for example, ref.) and short GRBs that form in the merger of …

The discovery of high-energy astrophysical neutrinos and the first hints of coincident
electromagnetic and neutrino emissions opened new opportunities in multi-messenger …

We report discovery of a bright, nearby () Sun-like star orbiting a dark object. We identified
the system as a black hole candidate via its astrometric orbital solution from the Gaia …

We present optical light curves, redshifts, and classifications for 365 spectroscopically
confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium …

Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some
are known to repeat, but most are single bursts. Nonrepeating FRB observations have had …

Merging neutron stars offer an excellent laboratory for simultaneously studying strong-field
gravity and matter in extreme environments. We establish the physical association of an …

Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that
the mass of the dark matter halo and the total stellar mass are coupled through a function …

We present a blind time-delay strong lensing (TDSL) cosmographic analysis of the doubly
imaged quasar SDSS 1206+ 4332. We combine the relative time delay between the quasar …

The final fate of massive stars, and the nature of the compact remnants they leave behind
(black holes and neutron stars), are open questions in astrophysics. Many massive stars are …

We present a catalog of galaxy clusters selected via their Sunyaev–Zel'dovich (SZ) effect
signature from 2500 deg 2 of South Pole Telescope (SPT) data. This work represents the …
