Knowledge of the progenitors of core-collapse supernovae is a fundamental component in
understanding the explosions. The recent progress in finding such stars is reviewed. The …

Young massive clusters (YMCs) are dense aggregates of young stars that form the
fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy …

The final evolution of stars in the mass range 70–140${\text {}}{M} _ {\odot} $ is explored.
Depending upon their mass loss history and rotation rates, these stars will end their lives as …

We present a catalog of the 26 currently known magnetars and magnetar candidates. We
tabulate astrometric and timing data for all catalog sources, as well as their observed …

Magnetars are the strongest magnets in the present universe and the combination of
extreme magnetic field, gravity and density makes them unique laboratories to probe current …

We show that energy deposited into an expanding supernova remnant by a highly magnetic
(B∼ 5× 10 14 G) neutron star spinning at an initial period of P i≈ 2–20 ms can substantially …

We present the results of a 10.5-yr, volume-limited (28-Mpc) search for supernova (SN)
progenitor stars. In doing so we compile all SNe discovered within this volume (132, of …

Long duration gamma-ray bursts (GRBs) originate from the core collapse of massive stars,
but the identity of the central engine remains elusive. Previous work has shown that rapidly …

Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray
repeaters, have been recognized in the last decade as the most promising candidates for …

Supernova remnants are beautiful astronomical objects that are also of high scientific
interest, because they provide insights into supernova explosion mechanisms, and because …
