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

We investigate the birth and evolution of Galactic isolated radio pulsars. We begin by
estimating their birth space velocity distribution from proper-motion measurements of …

We analyse the observed fractions of core-collapse supernova (SN) types from the Lick
Observatory Supernova Search (LOSS), and we discuss the corresponding implications for …

Asymmetry is required by most numerical simulations of stellar core-collapse explosions, but
the form it takes differs significantly among models. The spatial distribution of radioactive …

Powerful radio jets from active galactic nuclei are thought to be powered by the accretion of
material onto the supermassive black hole (the 'central engine'),. M87 is one of the closest …

No supernova (SN) in the Milky Way has been observed since the invention of the optical
telescope, instruments for other wavelengths, neutrino detectors, or gravitational wave …

We review the major advances in understanding the morphologies and kinematics of
supernova remnants (SNRs). Simulations of SN explosions have improved dramatically over …

The spatial and velocity distributions of nuclear species synthesized in the innermost
regions of core-collapse supernovae can yield important clues about explosion asymmetries …

The next galactic core-collapse supernova (CCSN) has already exploded, and its
electromagnetic (EM) waves, neutrinos, and gravitational waves (GWs) may arrive at any …

HST images of the young supernova remnant Cas A are used to explore the expansion and
spatial distribution of its highest velocity debris. ACS WFC images taken in 2004 March and …
