Kirkpatrick‐Baez (KB) and Lobster Eye (LE) Optics for Astronomical and Laboratory Applications

X-Ray Optics and Instrumentation, Volume 2010, Issue 1, 2010., 2010
Most of grazing incidence (reflective) X‐ray imaging systems used in astronomy and in other (laboratory) applications are based on the Wolter 1 (or modified) arrangement. But there were proposed also other designs and configurations, which are considered for future applications for both in laboratory and (finitely) in space.

A Modified Gravity and its Consequences for the Solar System, Astrophysics and Cosmology [PDF]

, 2006
A relativistic modified gravity (MOG) theory leads to a self-consistent, stable gravity theory that can describe the solar system, galaxy and clusters of galaxies data and cosmology.Comment: 16 pages. Latex file. Talk given at the International Workshop "

Fundamental Plane of Sunyaev-Zeldovich clusters

, 2007
Sunyaev-Zel'dovich (SZ) cluster surveys are considered among the most promising methods for probing dark energy up to large redshifts. However, their premise is hinged upon an accurate mass-observable relationship, which could be affected by the (rather ...

Neutrinos in Physics and Astrophysics

, 2003
The observed flavor oscillations of solar and atmospheric neutrinos determine several elements of the leptonic mixing matrix, but leave open the small mixing angle Theta_13, a possible CP-violating phase, the mass ordering, the absolute mass scale m_nu ...

New limits on dark matter annihilation from AMS cosmic ray positron data [PDF]

, 2013
The AMS experiment onboard the International Space Station has recently provided cosmic ray electron and positron data with unprecedented precision in the range from 0.5 to 350 GeV.

Minimal Dark Matter predictions for galactic positrons, anti-protons, photons

, 2008
We present the energy spectra of the fluxes of positrons, anti-protons and photons generated by Dark Matter annihilations in our galaxy, as univocally predicted by the model of Minimal Dark Matter.

Missing Thermal Energy of the Intracluster Medium

, 2007
The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9-sigma

Analytical treatment for the development of electromagnetic cascades in intense magnetic fields [PDF]

, 2018
In a strong magnetic field, a high-energy photon can be absorbed and then produce an electron-positron pair. The produced electron/positron will in turn radiate a high-energy photon via synchrotron radiation, which then initiates a cascade.

Scratches from the Past: Inflationary Archaeology through Features in the Power Spectrum of Primordial Fluctuations

, 2019
Inflation may provide unique insight into the physics at the highest available energy scales that cannot be replicated in any realistic terrestrial experiment.
