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).

Update on Light WIMP Limits: LUX, lite and Light

, 2014
We reexamine the current direct dark matter data including the recent CDMSlite and LUX data, assuming that the dark matter consists of light WIMPs, with mass close to 10 GeV/$c^2$ with spin-independent and isospin-conserving or isospin-violating ...

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.

The Past and Future of Light Dark Matter Direct Detection

, 2015
We review the status and future of direct searches for light dark matter. We start by answering the question: `Whatever happened to the light dark matter anomalies?' i.e.

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 ...

NuSTAR Hard X-Ray Monitoring of Gravitationally Lensed Quasar RX J1131–1231

The Astrophysical Journal, 2023
The X-ray emission from active galactic nuclei is believed to come from a combination of inverse Compton scattering of photons from the accretion disk and reprocessing of the direct X-ray emission by reflection.

Influence of Annealing on the Optical and Scintillation Properties of CaWO$_4$ Single Crystals

, 2012
We investigate the influence of oxygen annealing on the room temperature optical and scintillation properties of CaWO$_4$ single crystals that are being produced for direct Dark Matter search experiments.
