Sersiclets - A Matched Filter Generalisation of Shapelets for Weak Lensing Studies (2008)
Ngan, Wai-Hin Wayne, Van Waerbeke, Ludovic, Mahdavi, Andisheh, Heymans, Catherine, Hoekstra, Henk
The precision study of dark matter using weak lensing by large scale structure is strongly constrained by the accuracy with which one can measure galaxy shapes. Several methods have been devised but...
Powell, Leila C., Kay, Scott T., Babul, Arif, Mahdavi, Andisheh
Various differences in galaxy cluster properties derived from X-ray and weak lensing observations have been highlighted in the literature. One such difference is the observation of mass...

We use the suite of simulations presented in Poole et al (2006) to examine global X-ray and Sunyaev-Zel'dovich (SZ) observables for systems of merging relaxed X-ray clusters. In all of the scaling...

Dwarf galaxies in the Dynamically Evolved NGC 1407 Group (2006)
Trentham, Neil, Tully, R. Brent, Mahdavi, Andisheh
The NGC 1407 Group stands out among nearby structures by its properties that suggest it is massive and evolved. It shares properties with entities that have been called fossil groups: the 1.4...
XMM-Newton and Gemini Observations of Eight RASSCALS Galaxy Groups (2005)
Mahdavi, Andisheh, Finoguenov, Alexis, Böhringer, Hans, Geller, Margaret J., Henry, J. Patrick
I discuss a new gravitational potential, Phi(r) ~ (r_0^n+r^n)^(-1/n), for modeling the mass distribution of spherical systems. This potential has a finite mass and generates a density profile with...
Leonard, Douglas C., Filippenko, Alexei V., Li, Weidong, Matheson, Thomas, Kirshner, Robert P., Chornock, Ryan, ...
We present optical spectra and photometry sampling the first six months after discovery of supernova (SN) 1999gi in NGC 3184. SN 1999gi is shown to be a Type II-plateau event with a photometric...
The LX-sigma Relation for Galaxies and Clusters of Galaxies (2001)
Mahdavi, Andisheh, Geller, Margaret J.
We demonstrate that individual elliptical galaxies and clusters of galaxies form a continuous X-ray luminosity---velocity dispersion (LX-sigma) relation. Our samples of 280 clusters and 57 galaxies...

The Orbital Structure of Dark Matter Halos with Gas (2000)
With the success of the Chandra and XMM missions and the maturation of gravitational lensing techniques, powerful constraints on the orbital structure of cluster dark matter halos are possible. I...
The Cluster LX-sigma Relation Has Implications for Scale-Free Cosmologies (1999)
I show that the cluster LX-sigma relation should be sensitive to cosmologies with a scale-free power spectrum of initial density fluctuations, P(k) ~ k^n. I derive the dependence, and argue that a...
