SUMMARY:Simeon Bird (JHU) "Strong Absorbers in the Lyman-alpha Forest and Primordial Black Holes"
DESCRIPTION:Abstract:\nStrong HI absorbers are essentially the largest foreground contamination for Lyman alpha forest surveys\, and so a better understanding of them is necessary for achieving the goals of future Lyman alpha cosmology surveys. I will talk about a new automated technique for generating a probabilistic catalogue of strong absorbers for the entire survey\, allowing more robust cleaning of the foreground. Since no technique can entirely remove strong absorbers\, I will discuss new templates for characterising their effect on the flux power spectrum. A secondary systematic is induced by interpolation error between theoretical models\, and I will discuss techniques to mitigate this error with refining Gaussian Process emulators. Lastly I will discuss the interesting possibility that the surprisingly common mergers of ~30 solar mass black holes observed by LIGO could be primordial black hole dark matter\, which is intriguingly (still) not convincingly ruled out.

SUMMARY:Barnabas Poczos (CMU) Title: Distribution Regression and its Applications
DESCRIPTION:Abstract: \nThe most common machine learning algorithms operate on\nfinite-dimensional vectorial feature representations. In\nmany applications\, however\, the natural representation of the data\nconsists of more complex objects\,\nfor example functions\, distributions\, and sets\, rather than\nfinite-dimensional vectors. In this talk\nwe will discuss machine learning algorithms that can operate directly\non these complex\nobjects. For this purpose\, we use nonparametric statistical methods\nthat can consistently estimate the inner product\, distance\, and\ncertain kernel functions between distributions\, sets\, and other\nobjects. We will discuss applications in various scientific areas\nincluding cosmology (e.g. estimating the mass of galaxy clusters\,\nfinding anomalous galaxy clusters\, estimating the cosmological\nparameters of our Universe\, accelerating cosmological simulations)\,\nfluid dynamics (finding anomalous events in turbulence data)\,\nneuroimaging\, and agriculture

SUMMARY:Anthony Pullen (NYU) Title: Revealing CII Emission with LSS Cross-correlations
DESCRIPTION:Abstract:\n\nIn this talk\, I will present our joint measurement of cosmic infrared background (CIB) and CII line emission from large scales at redshift z=2.5 using an MCMC analysis of cross-correlations of the 3 high-frequency Planck bands with both SDSS-III quasars at z=2-3.2 and SDSS-III CMASS galaxies at z=0.43-0.7.  The CII emission is expected to correlate with the quasars and appear in the Planck 545 GHz band\, while the other cross-correlations are assumed to mostly be attributable to CIB-LSS correlations.  We report an excess emission inconsistent with the null result at 95% confidence\, with an intensity value favoring the higher range of CII models.  I will also forecast potential CII intensity constraints from Planck cross-correlated with DESI quasars.
