THE EXCURSION SET THEORY OF HALO MASS FUNCTIONS, HALO CLUSTERING, AND HALO GROWTH [PDF]

open access: yesInternational Journal of Modern Physics D, 2007
I review the excursion set theory with particular attention toward applications to cold dark matter halo formation and growth, halo abundance, and halo clustering. After a brief introduction to notation and conventions, I begin by recounting the heuristic argument leading to the mass function of bound objects given by Press and Schechter.

Halo nevus [PDF]

open access: yesMedicinski Glasnik Specijalne Bolnice za Bolesti Štitaste Žlezde i Bolesti Metabolizma "Zlatibor"
Halo nevi (leukoderma acquisitum centrifugum, Sutton's nevus, leukopigmentary nevus, perinevoid vitiligo or perinevoid leukoderma) are melanocytic nevi surrounded by a halo of hypopigmentation or depigmentation.

Melanoma with halo [PDF]

open access: yesClinical and Experimental Dermatology, 2009
We report this case of halo melanoma to stress that accurate clinical and dermatoscopical evaluation is essential in cases of PSL with a vitiligo-like halo, which may be misdiagnosed under the common belief that halos are associated with benign lesions.

HALO TRACTION [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1970
1. The usefulness of the halo method of traction in orthopaedic surgery, neurosurgery and plastic surgery is not widely appreciated. 2. Modifications of the apparatus are described and the technique of application is detailed. 3. Some advantages of the method are discussed.

A Curious “Halo” [PDF]

open access: yesNature, 1882
I TAKE the liberty of communicating an observation made on Saturday evening last between 8 o'clock p.m. and 8.15 p.m. of a sort of halo which appeared in the east-south-east, just over Killiney Hill. Near the horizon was a bank of heavy, slategray clouds coming up from the south, and from behind rose up a principal beam from the Telegraph Hill ...

Baryons and Their Halos [PDF]

open access: yesAIP Conference Proceedings, 2010
Galaxies are composed of baryonic stars and gas embedded in dark matter halos. Here I briefly review two aspects of the connection between baryons and their halos. (1) The observed baryon content of galaxies falls short of the cosmic baryon fraction by an amount that varies systematically with mass. Where these missing baryons now reside is unclear. (2)

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

open access: yes, 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 FIRST HALOS [PDF]

open access: yesThe Identification of Dark Matter, 2007
The size and time of formation of the first gravitationally bound objects in the Universe is set by the microphysical properties of the dark matter. It is argued that observations seem to favour cold and thermal candidates for the main contribution to the dark matter.

Nonlinear Bias of Cosmological Halo Formation in the Early Universe [PDF]

open access: yes, 2014
We present estimates of the nonlinear bias of cosmological halo formation, spanning a wide range in the halo mass from $\sim 10^{5} M_\odot$ to $\sim 10^{12} M_\odot$, based upon both a suite of high-resolution cosmological N-body simulations and ...

The Halo by Halo Missing Baryon Problem [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractThe global missing baryon problem – that the sum of observed baryons falls short of the number expected form BBN – is well known. In addition to this, there is also a local missing baryon problem that applies to individual dark matter halos.
