Searching for GRB remnants in nearby galaxies
S. G. Bhargavi, J. Rhoads, R. Perna +2
Gamma Ray Bursts (GRBs) are expected to leave behind GRB remnants, similar to how ``standard'' supernovae (SN) leave behind SN remnants. The identification of these remnants in our…
Pulsars With Jets May Harbor Dynamically Important Accretion Disks
Eric G. Blackman, Rosalba Perna
For many astrophysical sources with jets, there is evidence for the contemporaneous presence of disks. In contrast, pulsars such as the Crab and Vela show jets but have not yet rev…
Unveiling the multi-wavelength phenomenology of Anomalous X-ray Pulsars
GianLuca Israel, Luigi Stella, Stefano Covino +6
During 2002-2003 the number of IR-identified counterparts to the Anomalous X-ray Pulsars (AXPs) has grown to four (4U0142+614, 2E2259+584, 1E 1048-59 and 1RXS J170849-400910) out o…
Chandra Observations of the Dwarf Nova WX Hyi in Quiescence
Rosalba Perna, Jonathan McDowell, Kristen Menou +2
We report Chandra observations of the dwarf nova WX Hyi in quiescence. The X-ray spectrum displays strong and narrow emission lines of N, O, Mg, Ne, Si, S and Fe. The various ioniz…
A pulsar-atmosphere model for PSR 0656+14
D. A. Lloyd, R. Perna, P. Slane +2
We present a pulsar-atmosphere (PA) model for modulated thermal X-ray emission from cooling magnetized neutron stars. The model synthesizes the spectral properties of detailed stel…
Bondi Accretion and the Problem of the Missing Isolated Neutron Stars
Rosalba Perna, Ramesh Narayan, George Rybicki +2
A large number of neutron stars (NSs), ~10^9, populate the Galaxy, but only a tiny fraction of them is observable during the short radio pulsar lifetime. The majority of these isol…
