DOI: 10.1038/s41550-018-0531-z
Abstract: An anomalous emission component at energies of a few gigaelectronvolts and located towards the inner Galaxy is present in the Fermi-LAT data. At present, the two most promising explanations are the annihilation of dark matter… read more here.

DOI: 10.1051/0004-6361/201832786
Abstract: We study the $\gamma$-ray and broadband spectral energy distribution (SED) properties of a complete sample of 104 bright, radio-selected low-synchrotron peaked (LSP) blazars. Most of the sources have already been detected in the $\gamma$-ray band… read more here.

DOI: 10.1088/1475-7516/2018/10/010
Abstract: In the hierarchical paradigm of structure formation, galaxy clusters are the largest objects ever to virialize. They are thought to grow by accreting mass through large scale, strong virial shocks. Such a collisionless shock is… read more here.

DOI: 10.1088/1475-7516/2019/04/048
Abstract: Dark matter annihilations have been fiercely restricted by the non-observation of excess events in indirect detection probes. Typically the interactions that dictate annihilation are also present in the dark matter-nucleon scattering cross section, also severely… read more here.
