NANOGrav spectral index from melting domain walls
E. Babichev, D. Gorbunov, S. Ramazanov +2
We discuss cosmic domain walls described by a tension red-shifting with the expansion of the Universe. These melting domain walls emit gravitational waves with the low-frequency sp…
Dark photon production via elastic proton bremsstrahlung with non-zero momentum transfer
Dmitry Gorbunov, Ekaterina Kriukova
We explore hypothetical vector particles, dark photons , which mix with the Standard Model photons and thus mediate interactions with charged particles into the hidden sector.…
Scalar decay into pions via Higgs portal
Dmitry Gorbunov, Ekaterina Kriukova, Oleg Teryaev
In extensions of the Standard Model (SM) of particle physics a light scalar from a hidden sector can interact with known particles via mixing with the SM Higgs boson. If the scalar…
All-sky limits on Sterile Neutrino Galactic Dark Matter obtained with SRG/ART-XC after two years of operations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +12
Dark matter sterile neutrinos radiatively decay in the Milky Way, which can be tested with searches for almost monochromatic photons in the X-ray cosmic spectrum. We analyse the da…
