Reionization of the Local Group of galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2011
We present the first detailed structure formation and radiative transfer simulations of the reionization history of our cosmic neighbourhood. To this end, we follow the formation of the Local Group of galaxies and nearby clusters by means of constrained simulations, which use the available observational constraints to construct a representation of ...

On the cohomology of local groups [PDF]

Journal of the Australian Mathematical Society, 1971
Most known homology theories (e.g. the homology of modules, rings, groups, sheaves, …) have been found to be special cases of a general theory proposed by M. Barr and J. Beck [1], [2]. The aim of this paper is to show that the cohomology of a local group, as defined by W. T. van Est [4], also fits the scheme of Barr and Beck.

A Study of the Properties and Dynamics of the Disk of Satellites in a Milky-Way-like Galaxy System

Galaxies, 2023
The dynamics of the satellite systems of Milky-Way-like galaxies offer a useful means by which to study the galaxy formation process in the cosmological context. It has been suggested that the currently observed anisotropic distribution of the satellites

The C/M Ratio of AGB Stars in the Local Group Galaxies

Universe, 2022
The number ratio of carbon-rich to oxygen-rich asymptotic giant branch (AGB) stars (the so-called C/M ratio) is closely related to the evolution environment of the host galaxy.

Engaging community members to ensure culturally specific language is used in research: should I use gay, queer, MSM, or this other new acronym?

Research Involvement and Engagement, 2023
Researchers often use terminology to define their participant groups that is rooted in a clinical understanding of the group’s shared identity(ies).

Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?

Galaxies, 2021
It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy formation simulations in the standard dark matter-based ...

ON THE MASS OF THE LOCAL GROUP [PDF]

The Astrophysical Journal, 2014
We use recent proper motion measurements of the tangential velocity of M31, along with its radial velocity and distance, to derive the likelihood of the sum of halo masses of the Milky Way and M31. This is done using a sample halo pairs in the Bolshoi cosmological simulation of $ $CDM cosmology selected to match properties and environment of the Local

Improved access yet inequitable experience: gay, bisexual and other men who have sex with men’s views of more inclusive criteria for source plasma donation

BMC Public Health, 2023
Background Canada has incrementally reduced restrictions to blood and plasma donation that impact men who have sex with men, gay, bisexual, and queer men, and some Two Spirit, transgender and non-binary individuals (MSM/2SGBTQ+). Prior to the launch of a

Barriers and enablers to source plasma donation by gay, bisexual and other men who have sex with men under revised eligibility criteria: protocol for a multiple stakeholder feasibility study

Health Research Policy and Systems, 2020
Background Blood donation policy in Canada for gay, bisexual and other men who have had sex with men (gbMSM) has changed progressively in the last decade from indefinite deferral to 3-month deferral from last male-to-male sex.
