The article offers information on the debate among cosmologists regarding the rate of the universe's expansion, known as the Hubble constant. Topics include observations from NASA's James Webb Space Telescope confirming the discrepancy in the Hubble constant; the prevailing Lambda-cold dark matter (Lambda-CDM) model; and proposed solutions involving new physics and early-time scenarios to explain the disparity.

The article focuses on the use of cosmological simulations in helping refine theories of cosmology and galactic development. It states supercomputers are being used to simulate and predict galactic development, including how early galaxies were shaped like pickles, and that spiral galaxies can survive intergalactic collisions. It talks about simulating the interaction between baryonic matter, dark matter, and dark energy. It mentions how gas flows into galaxy follow dark matter filaments.

The article informs on the LUX-ZEPLIN (LZ) Experiment is a next-generation dark matter direct detection experiment hoping to observe weakly interacting massive particles (WIMP) scatters on nuclei. It mentions astronomical observations show, such as, that the stars in a typical galaxy swirl so fast that their collective gravity isn't strong enough to keep them from flying into space.

The article presents the discussion on physicists with an experiment called DAMA claiming the particles of dark matter including crystals of thallium-doped sodium iodide.

Now, Rebecca Leane, a theoretical particle physicist at MIT, and Juri Smirnov, an astroparticle physicist at the Ohio State University (OSU), suggest using exoplanets as dark matter detectors.

The article focuses on interpretation of data from the Alpha Magnetic Spectrometer (AMS) found on the International Space Station which could have resulted from collisions of dark matter particles (DMP). It states the AMS detected an unexpected positron flux starting at energies about 10 giga-electron volts (GeV) and fading around 300 GeV which physicist Samuel Ting theorizes was caused by DMP collisions which produce electron-positron pairs. It examines other explanations for the positrons.

PHOTO (COLOR): The spatial distribution of more than 4 million galaxies as measured by the Sloan Digital Sky Survey, which can't be easily explained by modifying gravity SDSS (CC-BY) Dark matter, the invisible stuff whose gravity is thought to hold galaxies together, may be the least satisfying concept in physics. According to cosmologists' prevailing theory, dark matter pervades pretty much every galaxy, providing the extra gravity that keeps stars from swirling out into space, given the speeds at which astronomers see the galaxies rotating.

PHOTO (COLOR): The XENON1T detector, which ran from 2016 to 2018, may have seen signs of exotic particles - or not. Enrico Sacchetti/Science Source An announcement today from physicists searching for particles of mysterious dark matter has set off a hype storm - even though the team says it hasn't actually discovered anything yet.

PHOTO (COLOR): By looking for x-rays coming from the sky between the stars, a team of physicists claims to have ruled out one possible type of dark matter. An ordinary neutrino can interact with an atomic nucleus; sterile neutrinos would only interact with other neutrinos, arising when an ordinary neutrino morphs into a sterile one through a process called neutrino mixing. Very rarely, a sterile neutrino would decay into an ordinary neutrino and an x-ray, which would have an energy equal to half the sterile neutrino's mass. [Extracted from the article]

PHOTO (COLOR): NASA's Fermi Gamma-ray Space Telescope has mapped the entire sky and found a faint, unexplained excess of gamma rays (inset) coming from around the center of our galaxy. Physicists think the entire Milky Way Galaxy lies embedded in a vast cloud of dark matter, like the swirl of color within a marble, with the dark matter densest in the middle.

The article talks about scientists searching for dark matter and not finding it in a favored dark matter candidate weakly interacting massive particles (WIMPs). It talks of physicists meeting at the University of Maryland, College Park to mull ideas for dark matter experiment sponsored by the U.S. Department of Energy. It also makes a mention of Continuous Electron Beam Accelerator Facility (CEBAF) at the Thomas Jefferson National Accelerator Facility supporting these experiments.

The article discusses research efforts of the XENON 1 Ton (XENON1T) particle detector in the Appennine Mountains, Italy and other detectors to discover weakly interacting massive particles (WIMPs), including WIMPs' status as dark matter. WIMP detectors' consisting of liquid xenon is discussed.

The article focuses on an Experiment to Detect the Global Epoch of Reionization Signature (EDGES) performed by researchers in the outback of Western Australia to study stars. Also includes analysis of dark matter by using array of three radio antennas, and existence of hydrogen atoms depicting the absorbed microwaves remaining from the big bang.

The article focuses on efforts made my scientists to find unseen dark matter after failure in searching for weakly interacting massive particles (WIMPs). Topics discussed include theorist Jonathan Feng's views on the research, a workshop on dark matter experiment for physicists at the University of Maryland at College Park sponsored by the U.S. Department of Energy, and Higgs bosons and neutrinos particle connecting to the dark sector.

The article reports that a team of astronomers has built the most detailed map of dark matter using the U.S. National Aeronautics and Space Administration's orbiting Hubble Space Telescope. Topics discussed include the clusters of galaxies that were studied, the use of gravitational lensing in the creation of the map, and the properties of the dark matter according to the study.

The article discusses differences among researchers about whether black holes are dark matter. Topics include the potential impact of dark matter on galaxies, the detection of fast radio bursts (FRBs) by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), and the discovery of a black hole merger by the Laser Interferometer Gravitational-Wave Observatory (LIGO).

The article discusses the rival theories of dark matter and modified Newtonian dynamics (MOND), the latter of which is a modification of Newton's law of motion. It references the astronomer Stacy McGaugh's research on MOND, including on the formation of spiral galaxies and on the impact that stars' accelerations have on galaxies.

The article discusses the possible opposition of the U.S. Congress to the recommendation of the Particle Physics Project Prioritization Panel (P5) for an international collaboration on the study of neutrinos for the future of the Fermi National Accelerator Laboratory (Fermilab) in Illinois. It also discusses its call for continued involvement in the Large Hadron Collider (LHC) project, increased funding for detecting particles of dark matter, and the Long-Baseline Neutrino Experiment (LBNE).

The article discusses the efforts by astronomers to seek rare galaxies in order to discover to what extent a galaxy is shaped by its surroundings. Astronomers have learned much about how galaxies like the Milky Way and Andromeda have formed but they do not know about the inner workings of the galaxies or their interaction with each other. Rare galaxies, which are isolated from their neighbors, may offer clues to how smaller dark matter clumps emerged from larger ones.

Focuses on the claims by three groups of researchers that they separately detected the dark matter infrastructure of the universe. Technique used by the teams to see dark matter; Effects of dark matter to distant galaxies.
