An infrared background-TeV gamma-ray crisis? [PDF]
Physics Letters B, 2000 We consider the implications of the recent determination of the universal infrared background for the propagation of photons up to 20 TeV from the active galaxy Markarian 501 as observed by HEGRA. At 20 TeV the mean free path for photon-photon collisions on the infrared background would be much shorter than the distance to Markarian 501, implying ...

The X‐Ray, Optical, and Infrared Counterpart to GRB 980703 [PDF]
The Astrophysical Journal, 1999 We report on X-ray, optical and infrared follow-up observations of GRB 980703. We detect a previously unknown X-ray source in the GRB error box; assuming a power law decline we find for its decay index alpha < -0.91 (3-sigma). We invoke host galaxy extinction to match the observed spectral slope with the slope expected from `fireball' models.

Design of Automatic Hand Sanitizer System Compatible with Various Containers [PDF]
Healthcare Informatics Research, 2020 Objectives Demand for hand sanitizers has surged since the coronavirus broke out and spread around the world. Hand sanitizers are usually applied by squirting the sanitizer liquid when one presses a pump with one’s hand.

INFRARED COUNTERPARTS OF X-RAY GALAXIES [PDF]
Odessa Astronomical Publications, 2019 Population studies of the extragalactic objects are a major part of the universe large-scale structure study. Apart from radio, infrared, and visible wavelength bands, observations and further identification of extragalactic objects such as galaxies, quasars, blazers, liners, and active star burst regions are also conducted in the X-ray and gamma bands.

AIP Advances, 2021 The human eye cannot recognize the shape of an object behind an opaque substrate; however, by reading and imaging infrared (IR) rays emitted from such an object, its shape behind the opaque substrate can be ascertained.

Infrared spectroscopy of Be/X-ray binaries [PDF]
Symposium - International Astronomical Union, 1994 We present infrared spectra of 4 Be/X-ray binaries in the K band, and 4 spectra in the J, H and K bands of 2 more sources. The HI IR emission lines are useful determinators of the conditions in the inner regions of the circumstellar disk about the Be star, due to optical depth effects.

INFRARED SUPERNOVA REMNANTS AND THEIR INFRARED-TO-X-RAY FLUX RATIOS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Recent high-resolution infrared space missions have revealed supernova remnants (SNRs) of diverse morphology in infrared (IR) dust emission that are often very different from their X-ray appearance. The observed range of infrared-to-X-ray (IRX) flux ratios of SNRs is also wide.
