LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF METHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS [PDF]

open access: yesQuímica Nova, 2020
Methanol (CH3OH) is one of the most abundant organic molecules in astrophysical environments. It has been found in cold regions such as surfaces of comets, ices near young stellar objects and protoplanetary disks, as well as in the gas phase in different

Radiolysis of ammonia-containing ices by energetic, heavy and highly charged ions inside dense astrophysical environments [PDF]

open access: yes, 2009
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 ...

Trapping mid-infrared rays in a lossy film with the Berreman mode, epsilon near zero mode, and magnetic polaritons.

open access: yesOptics Express, 2013
Triple mechanisms were employed to trap mid-infrared (mid-IR) rays within a semi-transparent SiO(2) film sandwiched between gold gratings and a gold substrate.

X-ray background synthesis: the infrared connection [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2003
We present a synthesis model of the X-ray background based on the cross-correlation between mid-infrared and X-ray surveys, where the distribution of type 2 sources is assumed to follow that of luminous infrared galaxies while type 1 sources are traced by the observed ROSAT distribution.

Infrared Sensor Detection and Actuator Treatment Applied during Hemodialysis

open access: yesSensors, 2020
Infrared thermography can be applied in different medical systems, for example it can be used to catch the images of living blood vessels. Far infrared rays can be used in a heating machine, which can be applied in the clinical hemodialysis patients ...

The Origin of Gamma-Rays from Globular Clusters [PDF]

open access: yes, 2010
Fermi has detected gamma-ray emission from eight globular clusters. We suggest that the gamma-ray emission from globular clusters may result from the inverse Compton scattering between relativistic electrons/positrons in the pulsar wind of MSPs in the ...

Multiple-Collision Free-Electron Laser Compton Backscattering for a High-Yield Gamma-Ray Source

open access: yesApplied Sciences, 2020
We observed multiple-collision free-electron laser (FEL)-Compton backscattering in which a multi-bunch electron beam makes head-on collisions with multi-pulse FELs in an optical cavity, using an infrared FEL system in the storage ring NIJI-IV.

The Cosmic Infrared Background: Measurements and Implications [PDF]

open access: yes, 2001
The cosmic infrared background records much of the radiant energy released by processes of structure formation that have occurred since the decoupling of matter and radiation following the Big Bang.

Mid-infrared variability of γ-ray emitting blazars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Using data from the Wide-field Infrared Survey Explorer, we studied the mid-infrared (mid-IR) 3.4 μm (W1-band) and 4.6 μm (W2-band) flux variability of γ-ray emitting blazars. Our sample consists of 460 flat spectrum radio quasars (FSRQs) and 575 BL Lacertae (BL Lac) objects.
