Extracting Star Formation Histories from Medium-resolution Galaxy Spectra
Hugues Mathis, Stephane Charlot, Jarle Brinchmann
We adapt an existing data compression algorithm, MOPED, to the extraction of median-likelihood star formation (SF) histories from medium-resolution galaxy spectra. By focusing on t…
Probing the Origins of Voids in the Distribution of Galaxies
Louise M. Ord, Martin Kunz, Hugues Mathis +1
If the voids that we see today in the distribution of galaxies existed at recombination, they will leave an imprint on the cosmic microwave background (CMB). On the other hand, if…
Probing the origins of voids with the CMB
L. M. Ord, M. Kunz, H. Mathis +1
In this talk presented at the 5th Rencontres du Vietnam 2004, we discuss our preliminary investigations into voids of primordial origin. We show that if voids in the cold dark matt…
Reconstruction of primordial density fields
Roya Mohayaee, Hugues Mathis, Stephane Colombi +1
The Monge-Ampere-Kantorovich (MAK) reconstruction is tested against cosmological N-body simulations. Using only the present mass distribution sampled with particles, and the assump…
The case for non-gaussianity on cluster scales
H. Mathis, J. M. Diego, Joseph Silk
We address whether possible scale-dependent deviations from gaussianity in the primordial density field that are consistent with the cosmic microwave background observations could…
On the formation of cold fronts in massive mergers
H. Mathis, G. Lavaux, J. M. Diego +1
Using adiabatic hydrodynamical simulations, we follow the evolution of two symmetric cold fronts developing in the remnant of a violent z=0.3 massive cluster merger. The structure…
