The imprint of dissipation on the shapes of merger remnant LOSVDs (2009)
Hoffman, Loren K., Cox, Thomas J., Dutta, Suvendra N., Hernquist, Lars E.
The properties of elliptical galaxies are broadly consistent with simulated remnants of gas-rich mergers between spirals, motivating more detailed studies of the imprint of this formation mechanism...
The Nature of the Ionising Background at z=2.5-5 (2002)
Sokasian, Aaron, Abel, Tom, Hernquist, Lars E.
Using radiative transfer calculations and cosmological simulations of structure formation, we study constraints that can be placed on the nature of the cosmic ultraviolet (UV) background in the...
The Epoch of Helium Reionization (2001)
Sokasian, Aaron, Abel, Tom, Hernquist, Lars. E.
We study the reionization of Helium II by quasars using a numerical approach that combines 3D radiative transfer calculations with cosmological hydrodynamical simulations. Sources producing the...
Simulating Reionization in Numerical Cosmology (2001)
Sokasian, Aaron, Abel, Tom, Hernquist, Lars E.
The incorporation of radiative transfer effects into cosmological hydrodynamical simulations is essential for understanding how the intergalactic medium (IGM) makes the transition from a neutral...
The Central X-Ray Point Source in Cassiopeia A (2000)
Chakrabarty, Deepto, Pivovaroff, Michael J., Hernquist, Lars E., Heyl, Jeremy S., Narayan, Ramesh
The spectacular first light observation by the Chandra X-Ray Observatory revealed an X-ray point source near the center of the 300 yr old Cas A supernova remnant. We present an analysis of the public...
