Dynamical flattening of halo density cusps by Q-ball dark matter
Alexander Libanov, Sergey Troitsky
Cold, collisionless dark matter successfully explains a wide range of observations, including the formation of large-scale structure. Nevertheless, tensions remain on small, galact…
Physics potential of the International Axion Observatory (IAXO)
E. Armengaud, D. Attie, S. Basso +88
We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particle…
Towards a medium-scale axion helioscope and haloscope
V. Anastassopoulos, F. Avignone, A. Bykov +32
We discuss the physics case for and the concept of a medium-scale axion helioscope with sensitivities in the axion-photon coupling a few times better than CERN Axion Solar Telescop…
Supermassive dark-matter Q-balls in galactic centers?
Sergey Troitsky
Though widely accepted, it is not proven that supermassive compact objects (SMCOs) residing in galactic centers are black holes. In particular, the Milky Way's SMCO can be a giant…
Constraining spacetime variations of nuclear decay rates from light curves of type Ia supernovae
Ivan Karpikov, Maxim Piskunov, Anton Sokolov +1
The luminosity of fading type Ia supernovae is governed by radioactive decays of 56Ni and 56Co. The decay rates are proportional to the Fermi coupling constant G_F and, therefore,…
Searching for energetic cosmic axions in a laboratory experiment: testing the PVLAS anomaly
M. Fairbairn, S. N. Gninenko, N. V. Krasnikov +4
Astrophysical sources of energetic gamma rays provide the right conditions for maximal mixing between (pseudo)scalar (axion-like) particles and photons if their coupling is as stro…
