The Impact of Dark Matter on Gravitational Wave Detection by Space-Based Interferometers
UniverseThe existence of dark matter is supported by multiple astrophysical observations, yet its particle nature remains unknown. The development of gravitational wave astronomy, especially with future space-based detectors such as LISA, provides new ...

Dark matter halos around galaxies
, 1997 We present evidence that all galaxies, of any Hubble type and luminosity, bear the kinematical signature of a mass component distributed differently from the luminous matter.

Dynamics and constraints of the massive gravitons dark matter flat cosmologies [PDF]
, 2011 We discuss the dynamics of the universe within the framework of Massive Graviton Dark Matter scenario (MGCDM) in which gravitons are geometrically treated as massive particles. In this modified gravity theory, the main effect of the gravitons is to alter

The Astrophysical JournalA fundamental prediction of the Lambda cold dark matter cosmology is the centrally divergent cuspy density profile of dark matter haloes. Density cusps render cold dark matter haloes resilient to tides, and protect dwarf galaxies embedded in them from ...

Unveiling Dark Matter with HI and Halpha Data - Observational Problems
, 2002 We present combined Halpha+HI rotation curves for a sample of spiral galaxies. Most of the velocity profiles (spectra at single points) in these galaxies are asymmetric, preventing the use of standard methods like the first moment analysis and the single

A new model of dark matter distribution in galaxies
, 2013 In the absence of the physical understanding of the phenomenon, different empirical laws have been used as approximation for distribution of dark matter in galaxies and clusters of galaxies.

Extended universal rotational curve of spiral galaxies
Discover SpaceIn this work, we aim to advance the Universal Rotation Curve (URC) paradigm by leveraging new data and extending its observational domain. Building on previous studies that established the URC using optical rotation curves reaching the galaxy optical ...

The distribution of dark matter in the coma cluster
The Astrophysical Journal, 1987 Limitations on positional and kinematical data for the distribution of dark matter in the Coma cluster are shown to cast doubt on any assumption of a constant M/L ratio. Attention is given to the possible forms of a smooth, spherical background potential (BP) for which positive phase space distribution functions that agree with available positions and ...
