Gravitational Redshift Detection from the Magnetic White Dwarf Harbored in RX J1712.6–2414

The Astrophysical Journal, 2023
Gravitational redshift is a fundamental parameter that allows us to determine the mass-to-radius ratio of compact stellar objects, such as black holes, neutron stars, and white dwarfs (WDs).

The CALorimetric Electron Telescope (CALET) for high-energy astroparticle physics on the International Space Station

EPJ Web of Conferences, 2015
The CALorimetric Electron Telescope (CALET) is a space experiment, currently under development by Japan in collaboration with Italy and the United States, which will measure the flux of cosmic-ray electrons (and positrons) up to 20 TeV energy, of gamma ...

Mirrors for Space Telescopes: Degradation Issues

Applied Sciences, 2020
Mirrors are a subset of optical components essential for the success of current and future space missions. Most of the telescopes for space programs ranging from earth observation to astrophysics and covering the whole electromagnetic spectrum from x ...

A Broadband X-Ray Study of the Dwarf Nova SS Cyg during Quiescence and Outburst

The Astrophysical Journal, 2023
We present a broadband X-ray study (∼0.3–50 keV) of the dwarf nova SS Cyg highlighting the changes in the accretion during two phases, the quiescence and the outburst states.

Mirror dark matter explanation of the DAMA, CoGeNT and CRESST-II data [PDF]

, 2012
Dark matter might reside in a hidden sector which contains an unbroken $U(1)'$ gauge interaction kinetically mixed with standard $U(1)_Y$. Mirror dark matter provides a well motivated example of such a theory.

Exothermic Double-Disk Dark Matter

, 2013
If a subdominant component of dark matter (DM) interacts via long-range dark force carriers it may cool and collapse to form complex structures within the Milky Way galaxy, such as a rotating dark disk.

“Teaching To the Test” Family of Fallacies

Revista Iberoamericana de Evaluación Educativa, 2017
This article explains the various meanings and ambiguities of the phrase “teaching to the test” (TttT), describes its history and use as a pejorative, and outlines the policy implications of the popular, but fallacious, belief that “high stakes” testing ...

Low-Mass Dark-Matter Hint from CDMS II, Higgs Boson at the LHC, and Darkon Models

, 2013
The CDMS II experiment has observed three events which may have arisen from weakly interacting massive particle (WIMP) dark matter (DM) with mass of order 9 GeV colliding with nuclei.

Multi-Scalar-Singlet Extension of the Standard Model - the Case for Dark Matter and an Invisible Higgs Boson

, 2012
We consider a simple extension of the Standard Model by the addition of N real scalar gauge singlets $\vp$ that are candidates for Dark Matter. By collecting theoretical and experimental constraints we determine the space of allowed parameters of the ...
