Events
IPAC organizes and hosts a number of meetings and conferences.
IPAC hosts seminars every Wednesday from 12-1pm in IPAC's Large Conference Room (102) except where noted. Directions can be found on the visitor information page. Pizza and soda are available for purchase at a modest fee. Some weeks, the Time Domain Forum talk (which is not a lunch talk) is held on Thursday afternoons at 2:30 pm.
To receive seminar notification emails, you may sign up here. If you are interested in presenting a talk or seminar, please contact Peter Capak (Extragalactic), or Stephen Kane (Galactic/Solar System/Exoplanets). To present at the Time Domain Forum, contact Luisa Rebull.

The ongoing Dark Energy Survey and other upcoming large-scale structure surveys aim to determine the composition of the Universe and the nature of dark energy by mapping the spatial distribution and shapes of hundreds of millions of galaxies. These data sets will enable precision measurements of various observables of large-scale structure, such as weak lensing, galaxy clustering, and the abundance of galaxy clusters. These observables probe different aspects of cosmic structure formation, and combining them improves constraints on cosmology significantly. In the first part of this talk I will introduce the analysis framework for the joint analysis of probes of large-scale structure currently under development for the Dark Energy Survey. In particular, I will discuss systematic uncertainties and cross-correlations of observables in detail, and outline extensions of these methods to future data sets from LSST and Euclid. In the second part of the talk I will describe some of my projects beyond the main cosmology analysis, such as constraining galaxy evolution with small-scale galaxy clustering and measurements of higher-order statistics.
