Observed x-ray spectral indices support magnetic buoyancy sourced coronae in Seyfert active galactic nuclei
Ketevan Kotorashvili, Eric G. Blackman
Standard radiation spectra modeling of active galactic nuclei like Seyfert galaxies typically involves tuning the relative contributions from an optically thick disc, optically thi…
Terrestrial atmospheric ion implantation occurred in the nearside lunar regolith during the history of Earth's dynamo
Shubhonkar Paramanick, Eric G. Blackman, John A. Tarduno +1
Light volatile elements in lunar regolith are thought to be a mixture of the solar wind and Earth's atmosphere, the latter sourced in the absence of geomagnetic field. However, the…
Tidally Delayed Spin-Down of Very Low Mass Stars
Ketevan Kotorashvili, Eric G. Blackman
Very low-mass main-sequence stars reveal some curious trends in observed rotation period distributions that require abating the spin-down that standard rotational evolution models…
Crystal Ball: A Simple Model for Phase Transitions on a Classical Spherical Lattice
Aidan Bachmann, Pierre-Alexandre Gourdain, Eric G. Blackman
When compressed, certain lattices undergo phase transitions that may allow nuclei to gain significant kinetic energy. To explore the dynamics of this phenomenon, we develop a frame…
Turbulence in Earth's core generates large topographic torques on the mantle
Tobias G. Oliver, Eric G. Blackman, John A. Tarduno +1
Seismic and geodynamic studies indicate that the boundary between the Earth's liquid outer core and solid mantle is not spherical, but is likely characterized by topography in the…
Relativistic Jet Motion in the Radio-quiet LINER Galaxy KISSR872
Preeti Kharb, Eric G. Blackman, Eric Clausen-Brown +5
We report superluminal jet motion with an apparent speed of in the radio-quiet (RQ) low ionisation nuclear emission line region (LINER) galaxy, KISSR87…
