A Halo Model with Environment Dependence: Theoretical Considerations [PDF]

, 2011
We present a modification of the standard halo model with the goal of providing an improved description of galaxy clustering. Recent surveys, like the Sloan Digital Sky Survey (SDSS) and the Anglo-Australian Two-degree survey (2dF), have shown that there

The Excursion Set Theory of Halo Mass Functions, Halo Clustering, and Halo Growth [PDF]

, 2006
I review the excursion set theory (EST) of dark matter halo formation and clustering. I recount the Press-Schechter argument for the mass function of bound objects and review the derivation of the Press-Schechter mass function in EST.

Non-Gaussian halo assembly bias [PDF]

, 2010
The strong dependence of the large-scale dark matter halo bias on the (local) non-Gaussianity parameter, f_NL, offers a promising avenue towards constraining primordial non-Gaussianity with large-scale structure surveys.

The Use and Complications of Halo Gravity Traction in Children with Scoliosis

Children, 2022
Scoliosis is one of the most frequent spine deformities encountered in children and is regularly discovered after 15 years of age with a girls to boys ratio of 2:1. Vertebral arthrodesis involves both short and long term complications.

Revising the motivation and confidence domain of the Canadian assessment of physical literacy

BMC Public Health, 2018
Background The Motivation and Confidence domain questionnaire in the Canadian Assessment of Physical Literacy (CAPL) was lengthy (36 single items that aggregate to five subscales), and thus burdensome to both participants and practitioners.

Reexamination of Mysticism in the Principles of Persian Miniatures Representing Muhammad’s (P.B.U.H.) Ascension [PDF]

پیکره, 2017
One can observe many Islamic and mystic representations in Persian miniatures the most salient of which are scenes depicting the Muhammad’s (P.B.U.H.) ascension (Miraj).

Investigation of the halo effect in the evolution of a nonstationary disk of spiral galaxies

Open Astronomy, 2023
In this article, we consider the problem of the evolution of the disk subsystem of galaxies, taking into account their halos. The global structure of the disk of galaxies strongly depends on the mass and shape of the halo.

Galaxy clustering in the NEWFIRM Medium Band Survey: the relationship between stellar mass and dark matter halo mass at 1 < z < 2 [PDF]

, 2010
We present an analysis of the clustering of galaxies as a function of their stellar mass at 1 < z < 2 using data from the NEWFIRM Medium Band Survey (NMBS). The precise photometric redshifts and stellar masses that the NMBS produces allows us to define a

Multi-Trophic Species Interactions Shape Seascape-Scale Coral Reef Vegetation Patterns

Frontiers in Ecology and Evolution, 2019
How species interactions shape habitat structure is a longstanding question in ecology. A curious phenomenon reflecting ecological self-organization around reef habitat structures exists on coral reefs: large-scale (hundreds to hundreds of thousands of ...
