Hypothetical low-mass particles, such as axions, provide a compelling explanation for the dark matter in the universe. Such particles are expected to emerge abundantly from the hot interior of stars. To test this prediction, the CERN Axion Solar Telescop
Detecting axionic dark matter (DM) could be possible in an X-ray spectrum from strongly magnetized neutron stars (NSs). We examine the possibility of axion–photon conversion in the magnetospheres of strongly magnetized NSs. In the current work, we investigate how the modified Tolman–Oppenheimer...
Planck-scale physics and solutions to the strongCPproblem without the axion We analyze the impact of quantum gravity on the possible solutions to the strong CP problem which utilize the spontaneously broken discrete symmetries, such as parity and time reversal invariance. We find that the stability...
For reference, we point out that in theoretical physics that there is no consensus on the nature of the axion. At this stage, all that matters to us is that the mass of the axion is small. This fact corresponds to the statement: “In the theory modified within the framework of the Gra...
This match would have profound implications for the physics of the early Universe and the dynamics of inflation. More work is necessary to explore this intriguing possibility. To conclude, it is worth stressing that a few more observable astrophysical effects are suitable to constrain the ...
Jason Steffens is an assistant professor of physics and astronomy at the University of Nevada, Las Vegas. Steffans' expertise include exoplanets, experimental searches for axion-like particles, dark energy, gravitation. Has the Big Bang Theory been proven?
While the described solution is perhaps the most appealing among other possible ideas, it did not come free of a new challenge for the contemporary physics. This is because the associated Nambu-Goldstone boson, i.e. the QCD axion, emerged as a plausible particle candidate [2, 3]. Although ...
Scientists call this point a "singularity," and it is very troubling because it means that, at the heart of a black hole, all the laws and theories of physics collapse like the dying stars that give rise to black holes in the first place. Read more: Was Oppenheimer, the father of the...
A once-in-a-civilization burst of gamma rays set off an observing spree by more than 160 telescopes. It’s forcing scientists to revisit long-held theories—and it’s not done yet.
