Astronomers from the Netherlands, the United Kingdom and the United States have found no trace of dark matter in AGC 114905, a gas-rich ultra-diffuse galaxy...
A black hole in the center of a dwarf spheroidal galaxy called Leo I is almost as massive as the central black hole of our own Milky Way Galaxy.
The dwarf...
Ultradiffuse galaxies are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low brightness, making them very difficult...
Singularities play an interesting role in physics, and come in many different varieties, from the mathematically and philosophically challenging to the...
Astrophysical observations show that supermassive black holes exist when the Universe is just 800 million years old after the Big Bang (just 6% of its...
In a new study, astronomers used data from the NASA/ESA Hubble Space Telescope to calculate a more accurate distance to an ultra-diffuse galaxy called...
Astronomers using ESO’s VLT Survey Telescope, a 2.6-m wide-field optical survey telescope at Paranal Observatory in Chile, have discovered 27 low-surface...
A team of astrophysicists from the United States and Korea has created a new dark-matter distribution map using a neural network-based deep learning method...
Dark matter with masses below 1 GeV can scatter, become captured, deposit annihilation energy, and increase the heat flow within extrasolar gas giants,...
Astronomers using data ESA’s Gaia mission and NASA’s Near Earth Object Wide Field Infrared Survey Explorer (NEOWISE) have created a map of the outermost...
Theoretical physicists from Italy, Spain and Argentina propose a new mechanism for the creation of supermassive black holes from dark matter.
Galaxy halos...
Astronomers using with the Australian National University 1.3-m SkyMapper telescope have detected an extended dark matter halo around Tucana II, an ultrafaint...
In a paper to be published in the journal Physics Letters B, a duo of theoretical physicists from the University of Sussex shows that quantum gravity leads...
If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful...
First theorized in the 1970s, axions are hypothetical particles that were proposed to preserve a time-reversal symmetry of the nuclear force. These particles...
