Infrared and visible scintillation of Ho3+-doped YAG and YLF crystals [PDF]
, 2018 In our effort to develop a new kind of detector for low-energy, low-rate energy deposition events we have investigated the cathodo- and radioluminescence of Ho:YAG and Ho:YLF single crystals in an extended wavelength range from 200 nm to 2200 nm.

Infrared identification of hard X-ray sources in the Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 The nature of the low- to intermediate-luminosity (Lx$\,\sim 10^{32-34}$ erg s$^{-1}$) source population revealed in hard band (2-10 keV) X-ray surveys of the Galactic Plane is poorly understood. To overcome such problem we cross-correlated the XMM-Newton 3XMM-DR4 survey with the infrared 2MASS and GLIMPSE catalogues.

The Nova V5584 Sgr: A Short Review
Acta Polytechnica CTU Proceedings, 2015 The nova V5584 Sgr was discovered during 2009 October. It has been monitored in different domains of the electromagnetic spectrum: optical, infrared and X-rays. The optical and infrared observations suggest that V5584 Sgr is a Fe II nova that formed dust.

Infrared-Selected “Warm” Galaxies Observed in X-rays [PDF]
Symposium - International Astronomical Union, 1989 The Infrared Astronomical Satellite (IRAS) has detected many galaxies in the infrared (IR), most of which have fairly steep 25μ to 60μ spectra. Many quasars and active galaxies exhibit a significantly flatter spectrum in the infrared. Several studies, for example, DeGrijp et al.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Gamma-Ray Cosmology and Tests of Fundamental Physics
Galaxies, 2022 The propagation of gamma-rays over cosmological distances is the subject of extensive theoretical and observational research at GeV and TeV energies. The mean free path of gamma-rays in the cosmic web is limited above 100 GeV due to the production of ...

Discovery of GeV emission from the direction of the luminous infrared galaxy NGC 2146
, 2014 Recent detection of high-energy gamma-ray emission from starburst galaxies M82 and NGC 253 suggests that starburst galaxies are huge reservoirs of cosmic rays and these cosmic rays convert a significant fraction of their energy into gamma-rays by ...

Bright Coherent Ultrahigh Harmonics in the keV X-ray Regime from Mid-Infrared Femtosecond Lasers [PDF]
Science, 2012 From Long to Short When you play a string instrument, you raise the frequency, or pitch, of the note by shortening the vibrating portion of the string: Drop the length in half, and you hear a harmonic at double the frequency.
