X-Rays from RS Ophiuchi’s 2021 Eruption: Shocks In and Out of Ionization Equilibrium

open access: yesThe Astrophysical Journal
The recurrent nova RS Ophiuchi (RS Oph) underwent its most recent eruption on 2021 August 8 and became the first nova to produce both detectable GeV and TeV emission.

The Source of Lake Wobegon [updated]

open access: yesNonpartisan Education Review, 2010
John J. Cannell's late 1980's "Lake Wobegon" reports suggested widespread deliberateeducator manipulation of norm-referenced standardized test (NRT) administrations and results,resulting in artificial test score gains.

Triplet seesaw model: from inflation to asymmetric dark matter and leptogenesis

open access: yes, 2012
The nature of dark matter (DM) particles and the mechanism that provides their measured relic abundance are currently unknown. Likewise, the nature of the inflaton is unknown as well. We investigate the triplet seesaw model in an unified picture. At high
