Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear matter melts into deconfined quark matter, liberating its c
In the scenario in which dark matter is formed as a thermal relic in the cooling early Universe, this criterion also selects the mass of the candidate particle. If dark matter is cold and collisionless, then galaxy formation proceeds via a hierarchical clustering [37,38], namely, from the ...
ChatGPT's impressive performance enables users to increasingly apply it to a variety of scenarios. However, previous studies investigating people's perceptions or attitudes towards ChatGPT have not considered the effects of the usage scenario. This paper aims to extract the representative scenarios of...
For such a disaster scenario to occur on Earth, strange matter would have to remain for more than a fraction of a second at earthly pressures, and we don't know if it can do that. It would also have to be negatively charged. In fact, potential strange matter would probably be positivel...
Cold Dark Matter In subject area: Physics and Astronomy Cold dark matter (CDM) refers to a type of dark matter produced in the early universe with low velocity, which does not significantly impact the formation of galaxies and large scale structures. AI generated definition based on: Physics ...
The suspension was further sonicated for cases in which a large population of ‘sticking’ particles were observed. The presence of stuck particles in the experimental data gives rise to small ‘dimer’ peaks at interparticle separations 2R in the measured g(r) which cannot be entirely eliminated...
which led to the person leaving academia, are in part due to a young very talented and inquisitive person being confronted with a (cosmological) model which does not agree with the data, but the important people in the research group enforcing this model to be the only one worthy to be st...
Alternative explanations drawn from current theory might be that these parent MNEs recognized potential for improving innovation within their internal networks, or that parent MNEs sought location advantages in the U.K. innovation system specific to pharmaceuticals technologies. In this scenario, the rapid...
On the other hand, in well-motivated top-down models such as mSUGRA, such degeneracy does not exist in general and often the lighter stau becomes the NLSP at the EW scale via renormalization group running, with the smuons/selectron masses lying slightly above. Con- sequently, a full mass ...
While this is our preferred scenario, it should be stressed that other PBH advocates favour a scenario in which most of the dark matter comprises PBHs in the planetary mass range and there are certainly formation mechanisms which would allow this. Indeed, it has been argued that the PBH mass...
