Simulations and Measurements of Warm Dark Matter Free-Streaming and Mass

引用

International Journal of Astronomy and Astrophysics 2019年第4期9卷 368-392页

作者： bruce Hoeneisen Universidad San Francisco de Quito Quito Ecuador

We compare simulated galaxy distributions in the cold ΛCDM and warm ΛWDM dark matter models. The ΛWDM model adds one parameter to the ΛCDM model, namely the cut-off wavenumber kfs of linear density perturbations. The challenge is to measure kfs. This study focuses on “smoothing lengths” π/kfs in the range from 12 Mpc to 1 Mpc. The simulations reveal two distinct galaxy populations at any given redshift z: hierarchical galaxies that form bottom up starting at the transition mas?Mfs, and stripped down galaxies that lose mass to neighboring galaxies during their formation, are near larger galaxies, often have filamentary distributions, and seldom fill voids. We compare simulations with observations, and present four independent measurements of kfs, and the mass mh of dark matter particles, based on the redshift of first galaxies, galaxy mass distributions, and rotation curves of spiral galaxies.

A Study of Dark Matter with Spiral Galaxy Rotation Curves. Part II

引用

International Journal of Astronomy and Astrophysics 2019年第2期9卷 133-141页

作者： bruce Hoeneisen Universidad San Francisco de Quito Quito Ecuador

In Part II of this study of spiral galaxy rotation curves we apply corrections and estimate all identified systematic uncertainties. We arrive at a detailed, precise, and self-consistent picture of dark matter.

The Adiabatic Invariant of Dark Matter in Spiral Galaxies

引用

International Journal of Astronomy and Astrophysics 2019年第4期9卷 355-367页

作者： bruce Hoeneisen Universidad San Francisco de Quito Quito Ecuador

Collisionless dark matter can only expand adiabatically. To test this idea and constrain the properties of dark matter, we study spiral galaxies in the “Spitzer Photometry and Accurate Rotation Curves” (SPARC) sample. Fitting the rotation curves, we obtain the root-mean-square (rms) velocity and density of dark matter in the core of the galaxies. We then calculate the rms velocity vhrms (1) that dark matter particles would have if expanded adiabatically from the core of the galaxies to the present mean density of dark matter in the universe. We obtain this “adiabatic invariant” vhrms (1) for 40 spiral galaxies. The distribution of vhrms (1) has a mean 0.87 km/s and a standard deviation of 0.27 km/s. This low relative dispersion is noteworthy given the wide range of the properties of these galaxies. The adiabatic invariant vhrms (1) may, therefore, have a cosmological origin. In this case, the rms velocity of non-relativistic dark matter particles in the early universe when density perturbations are still linear is vhrms (a)=vhrms (1)/a, where a is the expansion parameter. The adiabatic invariant obtains the ratio of dark matter temperature Th (a) to mass mh in the early universe.

A Study of Dark Matter with Spiral Galaxy Rotation Curves

引用

International Journal of Astronomy and Astrophysics 2019年第2期9卷 71-96页

作者： bruce Hoeneisen Universidad San Francisco de Quito Quito Ecuador

To constrain the properties of dark matter, we study spiral galaxy rotation curves measured by the THINGS collaboration. A model that describes a mixture of two self-gravitating non-relativistic ideal gases, “baryons” and “dark matter”, reproduces the measured rotation curves within observational uncertainties. The model has four parameters that are obtained by minimizing a x2 between the measured and calculated rotation curves. From these four parameters, we calculate derived galaxy parameters. We find that dark matter satisfies the Boltzmann distribution. The onset of Fermi-Dirac or Bose-einstein degeneracy obtains disagreement with observations and we determine, with 99% confidence, that the mass of dark matter particles is mh> 16 eV if fermions, or mh> 45 eV if bosons. We measure the root-mean-square velocity of dark matter particles in the spiral galaxies. This observable is of cosmological origin and allows us to obtain the root-mean-square velocity of dark matter particles in the early universe when perturbations were still linear. extrapolating to the past we obtain the expansion parameter at which dark matter particles become non-relativistic: ahNR=[4.17±0.34(STAT)±2.50(SYST)]×10−6. Knowing we then obtain the dark matter particle mass mh=69.0±4.2(stat)±31.0(syst)eV, and the ratio of dark matter-to-photon temperature Th/T=0.389±0.008(stat)±0.058(syst) after e+e−annihilation while dark matter remains ultra-relativistic. We repeat these measurements with ten galaxies with masses that span three orders of magnitude, and angular momenta that span five orders of magnitude, and obtain fairly consistent results. We conclude that dark matter was once in thermal equilibrium with the (pre?) Standard Model particles (hence the observed Boltzmann distribution) and then decoupled from the Standard Model and from self-annihilation at temperatures above mμ. These results disfavor models with freeze-out or freeze-in.

Propping up Propaganda？ exploring the Role of The Herald Newspaper in Strengthening ZANU-PF＇s Political Position

引用

Journalism and Mass Communication 2012年第12期2卷 1115-1126页

作者： bruce Mutsvairo University of Twente Enschede the Netherlands

This paper examines The Herald newspaper＇s role in safeguarding the seemingly unparalleled longevity of Zimbabwe＇s ruling Zimbabwe African National Union-Patriotic Front （ZANU-PF） party. Through an analysis of a sample of stories from both the paper＇s print and online editions, the study traces the origins of the broadsheet＇s ostensibly unflagging pro-ZANU-PF editorial positions, turning to article analysis to critically probe not only the motive but also the impact of the newspaper＇s assumed open allegiance to the revolutionary party. In a nation believed battered by perceived state brutality and widening political differences, The Herald has been accused of significantly influencing the pace of dictatorship while guardedly manipulating information to prop up President Robert Mugabe＇s party. So important has the paper become over the years that its often uncompromising, one-sided style of reporting has earned it praise among militant ZANU-PF hardliners while bitterly attracting widespread criticism from critics of the long-serving party.
