The Integrated Sachs-Wolfe Signal from BOSS Super-Structures
Benjamin R. Granett, András Kovács, Adam J. Hawken
Cosmic structures leave an imprint on the microwave background radiation through the integrated Sachs-Wolfe effect. We construct a template map of the linear signal using the SDSS-…
Revisiting the screening mechanism in gravity
Jian-hua He, Baojiu Li, Adam J. Hawken +1
We reexamine the screening mechanism in gravity using N-body simulations. By explicitly examining the relation between the extra scalar field and the gravitational p…
Massive Neutrinos Leave Fingerprints on Cosmic Voids
Christina D. Kreisch, Alice Pisani, Carmelita Carbone +5
Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As we vary the sum of the neutrino masses, we find void statistics contain information a…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory
eBOSS Collaboration, Shadab Alam, Marie Aubert +97
We present the cosmological implications from final measurements of clustering using galaxies, quasars, and Ly forests from the completed Sloan Digital Sky Survey (SDSS) lineag…
Primordial Non-Gaussianity
P. Daniel Meerburg, Daniel Green, Muntazir Abidi +175
Our current understanding of the Universe is established through the pristine measurements of structure in the cosmic microwave background (CMB) and the distribution and shapes of…
The Completed SDSS-IV Extended Baryon Oscillation Spectroscopic Survey: Growth rate of structure measurement from cosmic voids
Marie Aubert, Marie-Claude Cousinou, Stéphanie Escoffier +19
We present a void clustering analysis in configuration-space using the completed Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) DR16…
Effective dark matter power spectra in gravity
Jian-hua He, Baojiu Li, Adam J. Hawken
Using N-body simulations, we measure the power spectrum of the effective dark matter density field, which is defined through the modified Poisson equation in cosmologies. We…
Effective Dark Matter Halo catalog in gravity
Jian-hua He, Adam J. Hawken, Baojiu Li +1
We introduce the idea of {\it effective} dark matter halo catalog in gravity, which is built using the {\it effective} density field. Using a suite of high resolution N-body…
Constraints on the growth of structure around cosmic voids in eBOSS DR14
Adam J. Hawken, Marie Aubert, Alice Pisani +5
We present catalogues of cosmic voids identified in the distribution of Luminous Red Galaxies (LRGs) and Quasi Stellar Objects (QSOs) in the fourteenth data release (DR14) of the e…
