The spatial and temporal coincidence of gamma-ray burst (GRB) 980425 and supernova (SN) 1998bw has prompted speculation that there exists a subclass of GRBs produced by SNe ("S-GRBs"). A...

The origin of M32, the closest compact elliptical galaxy (cE), is a long-standing puzzle of galaxy formation in the Local Group. Our N-body/smoothed particle hydrodynamics simulations suggest a new...

Massive black holes appear to be present in the nuclei of almost all galaxies, but their genesis and evolution are not well understood. As astrophysical black holes are completely characterized by...

We have measured broadband optical BVR photometry of 24 classical and scattered Kuiper belt objects (KBOs), approximately doubling the published sample of colors for these classes of objects. We find...

In very fast coronal mass ejections (CMEs), it is possible for O vi ions to scatter Lyb photons that originate in the solar chromosphere and for the l1037 transition of O vi to scatter l1032 photons...
Shadowing-based reliability decay in softened n-body simulations (2003)
The Astrophysical Journal, Wayne B. Hayes
A shadow of a numerical solution to a chaotic system is an exact solution to the equations of motion that remains close to the numerical solution for a long time. In a collisionless n-body system, we...

We measure the central values (within ) of the Ca ii triplet line indices CaT* and CaT and the Paschen R /8 e index PaT at 8600 A for a 93% complete sample of 75 nearby early-type galaxies with mag...
