Tidally-induced thermonuclear Supernovae
S. Rosswog, E. Ramirez-Ruiz, W. R. Hix
We discuss the results of 3D simulations of tidal disruptions of white dwarfs by moderate-mass black holes as they may exist in the cores of globular clusters or dwarf galaxies. Ou…
A Survey for NV Absorption at z~z_GRB in GRB Afterglow Spectra: Clues to Gas Near the Progenitor Star
Jason X. Prochaska, Miroslava Dessauges-Zavadsky, Enrico Ramirez-Ruiz +1
We survey NV absorption in the afterglow spectra of long-duration gamma-ray bursts (GRBs) with the intent to study highly ionized gas in the galaxies hosting these events. We ident…
An infrared ring around the magnetar SGR 1900+14
S. Wachter, E. Ramirez-Ruiz, V. V. Dwarkadas +4
Magnetars are a special class of slowly rotating neutron stars with extremely strong magnetic fields -- at least an order of magnitude larger than those of the "normal" radio pulsa…
Simulating Black Hole White Dwarf Encounters
S. Rosswog, E. Ramirez-Ruiz, W. R. Hix +1
The existence of supermassive black holes lurking in the centers of galaxies and of stellar binary systems containing a black hole with a few solar masses has been established beyo…
