Low-Energy Astrophysics: Stimulating the Reduction of Energy Consumption in the Next Decade (2009)
Marshall, P. J., Bennert, N., Rykoff, E. S., Shen, K. J., Steinfadt, J. D. R., Fregeau, J., ...
In this paper we address the consumption of energy by astronomers while performing their professional duties. Although we find that astronomy uses a negligible fraction of the US energy budget, the...
Strong Gravitational Lensing as a Probe of Gravity, Dark-Matter and Super-Massive Black Holes (2009)
Koopmans, L. V. E., Auger, M., Barnabe, M., Bolton, A., Bradac, M., Ciotti, L., ...
Whereas considerable effort has been afforded in understanding the properties of galaxies, a full physical picture, connecting their baryonic and dark-matter content, super-massive black holes, and...
Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade (2009)
Marshall, P. J., Auger, M., Bartlett, J. G., Bradac, M., Cooray, A., Dalal, N., ...
The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans of cosmic distance...
The mass distribution of RX J1347-1145 from strong lensing (2008)
Halkola, A., Hildebrandt, H., Schrabback, T., Lombardi, M., Bradac, M., Erben, T., ...
High resolution HST/ACS images of the galaxy cluster RX J1347-1145 have enabled us to identify several new multiple image candidates in the cluster, including a 5 image system with a central image....
Bradac, M., Erben, T., Schneider, P., Hildebrand, H., Lombardi, M., Schirmer, M., ...
We have shown that the cluster-mass reconstruction method which combines strong and weak gravitational lensing data, developed in the first paper in the series, successfully reconstructs the mass...

The signature of substructure on gravitational lensing in the LCDM cosmological model (2003)
Bradac, M., Schneider, P., Lombardi, M., Steinmetz, M., Koopmans, L. V. E., Navarro, Julio F.
We present a study of the lens properties of quadruply imaged systems, lensed by numerically simulated galaxies. We investigate a simulated elliptical and disc galaxy drawn from high resolution...
Bradac, M., Schneider, P., Steinmetz, M., Lombardi, M., King, L., Porcas, R.
Gravitationally lensed systems with multiply imaged quasars are an excellent tool for studying the properties of distant galaxies. In particular, they provide the most accurate mass measures for the...
