The Galaxy–Halo Connection in Low-mass Halos [PDF]
The Astrophysical Journal Letters, 2019 Abstract Properties of galaxies vary systematically with the mass of their parent dark matter halos. This basic galaxy–halo connection shows a fair amount of scatter whose origin is not fully understood. Here, we study how differences in the halo assembly history affect central galaxies in low-mass (M halo < 1012

The Immitigable Nature of Assembly Bias: The Impact of Halo Definition on Assembly Bias [PDF]
MNRAS, 472, 1088-1105 (2017), 2017 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.

Halo exclusion criteria impacts halo statistics [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT Every halo-finding algorithm must make a critical yet relatively arbitrary choice: it must decide which structures are parent haloes, and which structures are subhaloes of larger haloes. We refer to this choice as percolation. We demonstrate that the choice of percolation impacts the statistical properties of the resulting halo ...

How are galaxies assigned to halos? Searching for assembly bias in the SDSS galaxy clustering [PDF]
, 2018 Clustering of dark matter halos has been shown to depend on halo properties beyond mass such as halo concentration, a phenomenon referred to as halo assembly bias.

The halo by halo missing baryon problem [PDF]
Proceedings of the International Astronomical Union, 2007 The 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. This halo by

Nature, 1882 THE phenomenon described in NATURE (vol. xxvi. pp. 268, 293, xxvii. p. 30) is far from being unknown in Europe, where it generally receives the title of “Rayons du Crepuscule”; although I do not think that it ever presents the brilliant appearance described by Father Marc Dechevrens as noticeable in China.

Clinical 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.

A physical and concise halo model based on the depletion radius [PDF]
, 2023 We develop a self-consistent and accurate halo model by partitioning matter according to the depletion radii of haloes. Unlike conventional models that define haloes with the virial radius while relying on a separate exclusion radius or ad-hoc fixes to account for halo exclusion, our model distributes mass across all scales self-consistently and ...

The 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.
