Zemp, Marcel, Ramirez-Ruiz, Enrico, Diemand, Jürg
Merging compact binaries are the one source of gravitational radiation so far identified. Because short-period systems which will merge in less than a Hubble time have already been observed as binary...
Simulations of Recoiling Massive Black Holes in the Via Lactea Halo (2009)
Guedes, Javiera, Madau, Piero, Kuhlen, Micheal, Diemand, Jürg, Zemp, Marcel
The coalescence of a massive black hole (MBH) binary leads to the gravitational-wave recoil of the system and its ejection from the galaxy core. We have carried out N-body simulations of the motion...
The structure and evolution of cold dark matter halos (2009)
In the standard cosmological model a mysterious cold dark matter (CDM) component dominates the formation of structures. Numerical studies of the formation of CDM halos have produced several robust...
Probing the Epoch of Reionization with Milky Way Satellites (2009)
Muñoz, Joseph A., Madau, Piero, Loeb, Abraham, Diemand, Jürg
While the connection between high-redshift star formation and the local universe has recently been used to understand the observed population of faint dwarf galaxies in the Milky Way (MW) halo, we...
The Graininess of Dark Matter Haloes (2008)
Zemp, Marcel, Diemand, Jürg, Kuhlen, Michael, Madau, Piero, Moore, Ben, Potter, Doug, ...
We use the recently completed one billion particle Via Lactea II LambdaCDM simulation to investigate local properties like density, mean velocity, velocity dispersion, anisotropy, orientation and...
Massive Black Hole Recoil in High Resolution Hosts (2008)
Guedes, Javiera, Diemand, Jürg, Zemp, Marcel, Kuhlen, Michael, Madau, Piero, Mayer, Lucio, ...
The final inspiral and coalescence of a black hole binary can produce highly beamed gravitational wave radiation. To conserve linear momentum, the black hole remnant can recoil with "kick" velocity...
Stadel, Joachim, Potter, Doug, Moore, Ben, Diemand, Jürg, Madau, Piero, Zemp, Marcel, ...
We perform a series of simulations of a Galactic mass dark matter halo at different resolutions, our largest uses over three billion particles and has a mass resolution of 1000 M_sun. We quantify the...
The Dark Matter Annihilation Signal from Galactic Substructure: Predictions for GLAST (2008)
Kuhlen, Michael, Diemand, Jürg, Madau, Piero
We present quantitative predictions for the detectability of individual Galactic dark matter subhalos in gamma-rays from dark matter pair annihilations in their centers. Our method is based on a...
GLAST and Dark Matter Substructure in the Milky Way (2007)
Kuhlen, Michael, Diemand, Jürg, Madau, Piero
We discuss the possibility of GLAST detecting gamma-rays from the annihilation of neutralino dark matter in the Galactic halo. We have used "Via Lactea", currently the highest resolution simulation...
The Stellar Mass Tully-Fisher Relation to z=1.2 from AEGIS (2007)
Kassin, Susan A., Weiner, Benjamin J., Faber, S. M., Koo, David C., Lotz, Jennifer M., Diemand, Jürg, ...
We combine newly measured rotation velocities, velocity dispersions, and stellar masses to construct stellar mass Tully-Fisher relations (M*TFRs) for 544 galaxies with strong emission lines at 0.1
Goerdt, Tobias, Gnedin, Oleg Y., Moore, Ben, Diemand, Jürg, Stadel, Joachim
If the dark matter particle is a neutralino then the first structures to form are cuspy cold dark matter (CDM) haloes collapsing after redshifts z ~ 100 in the mass range 10^{-6} - 10^{-3} Msun. We...
