An infrared background-TeV gamma-ray crisis? [PDF]
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 ...

Characteristics of Metabolic Calorific Values Measured by Infrared Thermal Imaging in Female Adults with Hashimoto's Thyroiditis: an Exploratory Analysis [PDF]
Background Hashimoto's thyroiditis (HT) is an autoimmune disease, and a major cause of hypothyroidism. Due to its insidious nature, non-presence of clear clinical symptoms, there is often a delay in getting a diagnosis for HT, which leads to ...

Radiolysis of ammonia-containing ices by energetic, heavy and highly charged ions inside dense astrophysical environments [PDF]
Deeply inside dense molecular clouds and protostellar disks, the interstellar ices are protected from stellar energetic UV photons. However, X-rays and energetic cosmic rays can penetrate inside these regions triggering chemical reactions, molecular ...

INFRARED COUNTERPARTS OF X-RAY GALAXIES
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.

Infrared spectroscopy of Be/X-ray binaries [PDF]
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]
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.

Utilização da imagem infravermelha em reumatologia Infrared imaging use in rheumatology
A imagem infravermelha (IR) é um método diagnóstico inócuo e sem radiação iônica, capaz de quantificar objetivamente por imagem as reações inflamatórias locais do sistema músculo-esquelético. Para o diagnóstico diferencial, a imagem IR deve ser analisada

Exploration of New Sensitizers for Photodynamic Therapy Targeting Deep Cancer Treatment
Despite its advantages, photodynamic therapy (PDT) has one major drawback: penetration depth. This limits the use of conventional PDT methods to skin (surface) tumors only, making it ineffective for deep tumors.

Infrared-Selected “Warm” Galaxies Observed in X-rays [PDF]
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.
