Soft X-ray Polarization in Thermal Magnetar Emission (2009)
Van Adelsberg, Matthew, Perna, Rosalba
Emission spectra from magnetars in the soft X-ray band likely contain a thermal component emerging directly from the neutron star surface. However, the lack of observed absorption-like features in...
Polarized X-rays from Magnetized Neutron Stars (2009)
Lai, Dong, Ho, Wynn C. G., Van Adelsberg, Matthew, Wang, Chen, Heyl, Jeremy S.
We review the polarization properties of X-ray emission from highly magnetized neutron stars, focusing on emission from the stellar surfaces. We discuss how x-ray polarization can be used to...
Spatial Structure and Collisionless Electron Heating in Balmer-dominated Shocks (2008)
Van Adelsberg, Matthew, Heng, Kevin, McCray, Richard, Raymond, John C.
Balmer-dominated shocks in supernova remnants (SNRs) produce strong hydrogen lines with a two-component profile composed of a narrow contribution from cold upstream hydrogen atoms, and a broad...
The Transition Zone in Balmer-Dominated Shocks (2007)
Heng, Kevin, Van Adelsberg, Matthew, McCray, Richard, Raymond, John C.
We examine the structure of the post-shock region in supernova remnants (SNRs). The ``shock transition zone'' is set up by charge transfer and ionization events between atoms and ions, and has a...

Magnetic Hydrogen Atmosphere Models and the Neutron Star RX J1856.5-3754 (2006)
Ho, Wynn C. G., Kaplan, David L., Chang, Philip, Van Adelsberg, Matthew, Potekhin, Alexander Y.
RX J1856.5-3754 is one of the brightest nearby isolated neutron stars, and considerable observational resources have been devoted to it. However, current models are unable to satisfactorily explain...
Thermal Radiation from Isolated Neutron Stars: Spectra and Polarizations (2006)
Recent observations of surface emission from isolated neutron stars (NSs) provide unique challenges to theoretical modeling of thermal radiative processes. We construct models of thermal emission...
Thermal Radiation from Isolated Neutron Stars: Spectra and Polarizations (2006)
Recent observations of surface emission from isolated neutron stars (NSs) provide unique challenges to theoretical modeling of thermal radiative processes. We construct models of thermal emission...
Van Adelsberg, Matthew, Lai, Dong
Theoretical modeling of surface emission from magnetized neutron stars (NSs) requires proper treatment of QED effects, in particular the effect of photon mode conversion due to the ``vacuum...
Radiation from condensed surface of magnetic neutron stars (2004)
Van Adelsberg, Matthew, Lai, Dong, Potekhin, Alexander Y., Arras, Phil
Recent observations show that the thermal X-ray spectra of many isolated neutron stars are featureless and in some cases (e.g., RX J1856.5-3754) well fit by a blackbody. Such a perfect blackbody...
