Cluster Mass Functions in the Large and Small Magellanic Clouds: Fading and Size-of-Sample Effects
- D. Hunter, B. Elmegreen, T. Dupuy, M. Mortonson
- Physics
- 25 June 2003
The properties of ∼939 star clusters in the Large and Small Magellanic Clouds were determined from ground-based CCD images in UBVR passbands. The areal coverage was extensive, corresponding to 11.0…

Size Is Everything: Universal Features of Quasar Microlensing with Extended Sources
- M. Mortonson, P. Schechter, J. Wambsganss
- Physics, Geology
- 10 August 2004
We examine the effect that the shape of the source brightness profile has on the magnitude fluctuations of images in quasar lens systems due to microlensing. We do this by convolving a variety of…
A joint analysis of Planck and BICEP2 B modes including dust polarization uncertainty
- M. Mortonson, U. Seljak
- Physics, Geology
- 22 May 2014
We analyze BICEP2 and Planck data using a model that includes CMB lensing, gravity waves, and polarized dust. Recently published Planck dust polarization maps have highlighted the difficulty of…
Simultaneous falsification of Λ CDM and quintessence with massive, distant clusters
- M. Mortonson, Wayne Hu, D. Huterer
- Physics
- 29 October 2010
Observation of even a single massive cluster, especially at high redshift, can falsify the standard cosmological framework consisting of a cosmological constant and cold dark matter…
Model-Independent Constraints on Reionization from Large-Scale Cosmic Microwave Background Polarization
- M. Mortonson, Wayne Hu
- Physics
- 8 May 2007
On large angular scales, the polarization of the CMB contains information about the evolution of the average ionization during the epoch of reionization. Interpretation of the polarization spectrum…
Mechanical loss in tantala/silica dielectric mirror coatings
- S. Penn, P. Sneddon, C. Vassiliou
- Physics, Materials Science
- 24 February 2003
Current interferometric gravitational wave detectors use test masses with mirror coatings formed from multiple layers of dielectric materials, most commonly alternating layers of SiO2 (silica) and…
WFIRST-2.4: What Every Astronomer Should Know
- D. Spergel, N. Gehrels, S. Shaklan
- Physics
- 23 May 2013
The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. The report of the WFIRST-AFTA Science Definition Team (SDT)…
Bayesian Analysis of Inflation: Parameter Estimation for Single Field Models
- M. Mortonson, H. Peiris, R. Easther
- Physics
- 23 July 2010
Future astrophysical data sets promise to strengthen constraints on models of inflation, and extracting these constraints requires methods and tools commensurate with the quality of the data. In this…
