Frontiers in Astronomy and Space SciencesIt is postulated that the energy density of the (quantum) vacuum acts firstly as dark energy and secondly as a part of dark matter. Assisted by electric fields arising from a small charge mismatch in the cosmic plasma, it can condense on mass ...

Journal of Astrophysics & Aerospace Technology, 2017 How Stars are formed? At the center of the galaxy we have what is referred to as a black hole. I would describe it as a proton star with similarity to how a stars mechanics work only in the opposite way. Because of the negative polarity protons flow in and are converted to electron.

Form flows function: Learner‐centered game Re‐design in a STEM classroom
British Educational Research Journal, EarlyView.Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Chemie Ingenieur Technik, EarlyView.All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

On the Non-Thermal Energy Content of Cosmic Structures
Galaxies, 2016 (1) Background: the budget of non-thermal energy in galaxy clusters is not well constrained, owing to the observational and theoretical difficulties in studying these diluted plasmas on large scales; (2) Method: we use recent cosmological simulations ...

The Astrophysical JournalThe tip of the red giant branch (TRGB) provides a key standard candle for extragalactic distance measurements and for refining the Hubble constant. We test its robustness by quantifying how metallicity, α -element enhancement, age, and initial helium ...

Classical novae and type I X-ray bursts: Challenges for the 21st century
AIP Advances, 2014 Classical nova explosions and type I X-ray bursts are the most frequent types of thermonuclear stellar explosions in the Galaxy. Both phenomena arise from thermonuclear ignition in the envelopes of accreting compact objects in close binary star systems ...

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...
