Background Modeling for Double Higgs Boson Production: Density Ratios and Optimal Transport
Tudor Manole, Patrick Bryant, John Alison +2
We study the problem of data-driven background estimation, arising in the search of physics signals predicted by the Standard Model at the Large Hadron Collider. Our work is motiva…
Cosmic Web Reconstruction through Density Ridges: Catalogue
Yen-Chi Chen, Shirley Ho, Jon Brinkmann +4
We construct a catalogue for filaments using a novel approach called SCMS (subspace constrained mean shift; Ozertem & Erdogmus 2011; Chen et al. 2015). SCMS is a gradient-based met…
Detecting Effects of Filaments on Galaxy Properties in the Sloan Digital Sky Survey III
Yen-Chi Chen, Shirley Ho, Rachel Mandelbaum +6
We study the effects of filaments on galaxy properties in the Sloan Digital Sky Survey (SDSS) Data Release 12 using filaments from the `Cosmic Web Reconstruction' catalogue (Chen e…
Investigating Galaxy-Filament Alignments in Hydrodynamic Simulations using Density Ridges
Yen-Chi Chen, Shirley Ho, Ananth Tenneti +6
In this paper, we study the filamentary structures and the galaxy alignment along filaments at redshift in the MassiveBlack-II simulation, a state-of-the-art, high-resolut…
Cosmic Web Reconstruction through Density Ridges: Method and Algorithm
Yen-Chi Chen, Shirley Ho, Peter E. Freeman +2
The detection and characterization of filamentary structures in the cosmic web allows cosmologists to constrain parameters that dictates the evolution of the Universe. While many f…
Nonparametric 3D map of the IGM using the Lyman-alpha forest
Jessi Cisewski, Rupert A. C. Croft, Peter E. Freeman +4
Visualizing the high-redshift Universe is difficult due to the dearth of available data; however, the Lyman-alpha forest provides a means to map the intergalactic medium at redshif…
