    • AbacusSummit: Next Generation N-Body Cosmology 

      Maksimova, Nina (2022-05-12)
      Cosmological N-body simulations have long been the standard forward modelling tool for interpreting measurements of the large-scale structure (LSS) of the Universe. As Stage IV LSS surveys such as the Dark Energy Spectroscopic ...

    • Dark and Light: Unifying the Origins of Dark and Visible Matter 

      Shuve, Brian (2012-07-23)
      The Standard Model of particle physics can account for neither the dark matter dominating the universe's matter density, nor the baryon asymmetry that leads to the visible matter density. This dissertation explores models ...

    • Galaxy Clustering in Early Sloan Digital Sky Survey Redshift Data 

      Zehavi, Idit; Blanton, Michael R.; Frieman, Joshua A.; Weinberg, David H.; Mo, Houjun J.; Strauss, Michael A.; Anderson, Scott F.; Annis, James; Bahcall, Neta A.; Bernardi, Mariangela; Briggs, John W.; Brinkmann, Jon; Burles, Scott; Carey, Larry; Castander, Francisco J.; Connolly, Andrew J.; Csabai, Istvan; Dalcanton, Julianne J.; Dodelson, Scott; Doi, Mamoru; Eisenstein, Daniel James; Evans, Michael L.; Finkbeiner, Douglas; Friedman, Scott; Fukugita, Masataka; Gunn, James E.; Hennessy, Greg S.; Hindsley, Robert B.; Ivezic, Zeljko; Kent, Stephen; Knapp, Gillian R.; Kron, Richard; Kunszt, Peter; Lamb, Donald Q.; Leger, R. French; Long, Daniel C.; Loveday, Jon; Lupton, Robert H.; McKay, Timothy; Meiksin, Avery; Merrelli, Aronne; Munn, Jeffrey A.; Narayanan, Vijay; Newcomb, Matt; Nichol, Robert C.; Owen, Russell; Peoples, John; Pope, Adrian; Rockosi, Constance M.; Schlegel, David; Schneider, Donald P.; Scoccimarro, Roman; Sheth, Ravi K.; Siegmund, Walter; Smee, Stephen; Snir, Yehuda; Stebbins, Albert; Stoughton, Christopher; SubbaRao, Mark; Szalay, Alexander S.; Szapudi, Istvan; Tegmark, Max; Tucker, Douglas L.; Uomoto, Alan; Vanden Berk, Dan; Vogeley, Michael S.; Waddell, Patrick; Yanny, Brian; York, Donald G.; undefined, undefined (IOP Publishing, 2002)
      We present the first measurements of clustering in the Sloan Digital Sky Survey (SDSS) galaxy redshift survey. Our sample consists of 29,300 galaxies with redshifts 5700 km s-1 ≤ cz ≤ 39,000 km s-1, distributed in several ...

    • Hints of a Hidden World 

      Cesarotti, Cari (2022-05-12)
      Despite extensive theoretical and experimental efforts, we have yet to discover evidence of new physics. Since there is no obvious candidate for a particular new physics model that can resolve the variety of anomalies and ...

    • The mass profile of the Milky Way to the virial radius from the Illustris simulation 

      Taylor, Corbin; Boylan-Kolchin, Michael; Torrey, Paul; Vogelsberger, Mark; Hernquist, Lars Eric (Oxford University Press (OUP), 2016)
      We use particle data from the Illustris simulation, combined with individual kinematic constraints on the mass of the Milky Way (MW) at specific distances from the Galactic Centre, to infer the radial distribution of the ...

    • Modelling galactic conformity with the colour–halo age relation in the Illustris simulation 

      Bray, Aaron; Pillepich, Annalisa; Sales, Laura V.; Zhu, Emily Chengxi; Genel, Shy; Rodriguez-Gomez, Vicente; Torrey, Paul; Nelson, Dylan; Vogelsberger, Mark; Springel, Volker; Eisenstein, Daniel James; Hernquist, Lars Eric (Oxford University Press (OUP), 2015)
      Comparisons between observational surveys and galaxy formation models find that dark matter haloes’ mass can largely explain their galaxies’ stellar mass. However, it remains uncertain whether additional environmental ...

    • Signals of Particle Dark Matter 

      Lin, Tongyan (2012-09-07)
      This thesis explores methods of detecting dark matter particles, with some emphasis on several dark matter models of current interest. Detection in this context means observation of an experimental signature correlated ...

    • Towards better interpretation of the small-scale structure of the Universe 

      Yuan, Sihan (2021-05-06)
      There is a trove of cosmological information in the structure of the Universe on small scales (1-20Mpc). Revealing this information is of increasing interest as we exhaust the constraining power of the large scale (~100Mpc). ...

    • Updated Kinematic Constraints on a Dark Disk 

      Kramer, Eric David; Randall, Lisa (American Astronomical Society, 2016)
      We update the method of the Holmberg & Flynn (2000) study, including an updated model of the Milky Way’s interstellar gas, radial velocities, an updated reddening map, and a careful statistical analysis, to bound the allowed ...
