An X-Ray View of the Cataclysmic Variable V902 Mon: Discovery of an X-Ray Eclipse

The Astrophysical Journal
V902 Mon is one of a few eclipsing intermediate polars (IPs) and shows deep eclipses in the optical lightcurves. The presence of a strong Fe K α fluorescence line in its X-ray spectrum and its low X-ray flux compared to other IPs suggests significant ...

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

The 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.

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

, 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

XMM-Newton Observations of Flares and a Possible Pulse Dropout in the Supergiant X-Ray Binary 4U 1909+07

The Astrophysical Journal
We report on a pair of X-ray Multi-Mirror Mission (XMM-Newton) observations of the Supergiant X-ray binary 4U 1909+07, which were performed on 2021 October 3 and 8, respectively.

The Source of Lake Wobegon [updated]

Nonpartisan 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.

Improved He-like Kα Line Diagnostics for Photoionized Plasmas

The Astrophysical Journal
The helium-like K α line complexes are valuable diagnostics of the electron density, temperature, and ionization conditions of astrophysical plasmas. The ratios of these lines can be altered by the presence of lithium-like ions through both inner-shell ...

Direct Detection of Dark Matter particles with Long Range Interaction

, 2012
We study the effect of a long-range DM-nuclei interaction occurring via the exchange of a light mediator. We consider the main direct detection experiments: DAMA, CoGeNT, CRESST, CDMS and XENON100.
