Detection of a Dark Substructure through Gravitational Imaging (2009)
Vegetti, S., Koopmans, L. V. E., Bolton, A., Treu, T., Gavazzi, R.
We report the detection of a dark substructure through direct gravitational imaging - undetected in the HST-ACS F814W image - in the gravitational lens galaxy of SLACS SDSSJ0946+1006 (the "Double...
Koopmans, L. V. E., Bolton, A., Treu, T., Czoske, O., Auger, M. W., Barnabe, M., ...
Based on 58 SLACS strong-lens early-type galaxies with direct total-mass and stellar-velocity dispersion measurements, we find that inside one effective radius massive elliptical galaxies with M_eff...
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...
Chapter 16. Scientific Ethics 1 (2008)
Scientific ethics, defined as the standards of conduct for scientists in their professional endeavors, covers a broad swath of activities from issues handled by White House advisory groups on topics...
Spiral Disk Opacity from Occulting Galaxy Pairs in the Sloan Digital Sky Survey (2007)
Holwerda, B. W., Keel, W. C., Bolton, A.
A spiral galaxy partially ovelapping a more distant elliptical offers an unique opportunity to measure the dust extinction in the foreground spiral. From the Sloan Digital Sky Survey DR4...
An expectation-maximization (EM) approach to spectral structure identification and estimation (2001)
Viola, M., Bolton, A., Moran, B.
Many problems in signal processing require the estimation of the significant frequency components of a signal; that is, of the frequency, amplitude and phase. In particular such problems arise in...

De Kort, G, Bolton, A, Martin, G, Stephen, J, Van De Klundert, J A
The outer membrane protein OmpX of Enterobacter cloacae shows high amino acid homology with virulence proteins PagC and Rck from Salmonella typhimurium and with Ail from Yersinia enterocolitica. Here...
