Mapping the Real Space Distributions of Galaxies in SDSS DR7: II. Measuring the growth rate, clustering amplitude of matter and biases of galaxies at redshift
Feng Shi, Xiaohu Yang, Huiyuan Wang +9
We extend the real-space mapping method developed in Shi et at. (2016) so that it can be applied to flux-limited galaxy samples. We use an ensemble of mock catalogs to demonstrate…
ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
Cold Filamentary Accretion and the Formation of Metal Poor Globular Clusters and Halo Stars
Nir Mandelker, Pieter G. van Dokkum, Jean P. Brodie +2
We propose that cold filamentary accretion in massive galaxies at high redshift can lead to the formation of star-forming clumps in the halos of these galaxies without the presence…
Modelling the line-of-sight contribution in substructure lensing
Giulia Despali, Simona Vegetti, Simon D. M. White +2
We investigate how Einstein rings and magnified arcs are affected by small-mass dark-matter haloes placed along the line-of-sight to gravitational lens systems. By comparing the gr…
SDSS-IV MaNGA: Uncovering the Angular Momentum Content of Central and Satellite Early-type Galaxies
Jenny E. Greene, Alexie Leauthaud, Eric Emsellem +18
We study 379 central and 159 satellite early-type galaxies with two-dimensional kinematics from the integral-field survey Mapping Nearby Galaxies at APO (MaNGA) to determine how th…
The Galaxy Clustering Crisis in Abundance Matching
Duncan Campbell, Frank C. van den Bosch, Nikhil Padmanabhan +5
Galaxy clustering on small scales is significantly under-predicted by sub-halo abundance matching (SHAM) models that populate (sub-)haloes with galaxies based on peak halo mass, $M…
Brightest galaxies as halo centre tracers in SDSS DR7
Johannes U. Lange, Frank C. van den Bosch, Andrew Hearin +4
Determining the positions of halo centres in large-scale structure surveys is crucial for many cosmological studies. A common assumption is that halo centres correspond to the loca…
The Immitigable Nature of Assembly Bias: The Impact of Halo Definition on Assembly Bias
Antonia S. Villarreal, Andrew R. Zentner, Yao-Yuan Mao +6
Dark matter halo clustering depends not only on halo mass, but also on other properties such as concentration and shape. This phenomenon is known broadly as assembly bias. We explo…
Mapping substructure in the HST Frontier Fields cluster lenses and in cosmological simulations
Priyamvada Natarajan, Urmila Chadayammuri, Mathilde Jauzac +14
We map the lensing-inferred substructure in the first three clusters observed by the Hubble Space Telescope Frontier Fields Initiative (HSTFF): Abell 2744 (z = 0.308), MACSJ0416, (…
