The alignment of galaxy spin with the shear field in observations

Isha Pahwa, Noam I. Libeskind, Elmo Tempel +6

Tidal torque theory suggests that galaxies gain angular momentum in the linear stage of structure formation. Such a theory predicts alignments between the spin of haloes and tidal…

The large-scale 3-point correlation function of the SDSS BOSS DR12 CMASS galaxies

Zachary Slepian, Daniel J. Eisenstein, Florian Beutler +15

We report a measurement of the large-scale 3-point correlation function of galaxies using the largest dataset for this purpose to date, 777, 202 Luminous Red Galaxies in the Sloan…

Deja Vu All Over Again: The Reappearance of Supernova Refsdal

P. L. Kelly, S. A. Rodney, T. Treu +21

In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…

Measuring Baryon Acoustic Oscillations from the clustering of voids

Yu Liang, Cheng Zhao, Chia-Hsun Chuang +2

We investigate the necessary methodology to optimally measure the baryon acoustic oscillation (BAO) signal, from voids based on galaxy redshift catalogues. To this end, we study th…

DIVE in the cosmic web: voids with Delaunay Triangulation from discrete matter tracer distributions

Cheng Zhao, Charling Tao, Yu Liang +2

We present a novel parameter-free cosmological void finder (\textsc{dive}, Delaunay TrIangulation Void findEr) based on Delaunay Triangulation (DT), which efficiently computes the…

MultiDarkLens Simulations: weak lensing light-cones and data base presentation

Carlo Giocoli, Eric Jullo, R. Benton Metcalf +10

In this paper we present a large database of weak lensing light cones constructed using different snapshots from the Big MultiDark simulation (BigMDPL). The ray-tracing through dif…
