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

Infrared Dichroism from the X-Ray Structure of Bacteriorhodopsin [PDF]
Biophysical Journal, 2001 A detailed comparison with the three-dimensional protein structure provides a stringent test of the models and parameters commonly used in determining the orientation of the alpha-helices from the linear dichroism of the infrared amide bands, particularly in membranes.

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

Cosmogenic Neutrinos from Cosmic Ray Interactions with Extragalactic Infrared Photons [PDF]
Phys.Rev.D73:043003,2006, 2005 We discuss the production of cosmogenic neutrinos on extragalactic infrared photons in a model of its cosmological evolution. The relative importance of these infrared photons as a target for proton interactions is significant, especially in the case of steep injection spectra of the ultrahigh energy cosmic rays.

Impact of Low-Energy Cosmic Rays on Star Formation [PDF]
, 2020 In recent years, exciting developments have taken place in the identification of the role of cosmic rays in star-forming environments. Observations from radio to infrared wavelengths and theoretical modelling have shown that low-energy cosmic rays ( < 1

Luminous infrared galaxies as plausible gamma-ray sources for GLAST and IACTs [PDF]
Astrophys.J. 607 (2004) L99-L102, 2004 We argue that luminous infrared galaxies (LIGs) may constitute a newly detectable population of gamma-ray sources for the next generation of ground and space-based high energy telescopes. Additionally, we report for the first time upper limits on their fluxes using data obtained with the EGRET telescope.

Simultaneous X-Ray and Infrared Observations of Sagittarius A*'s Variability [PDF]
The Astrophysical Journal, 2019 Abstract Emission from Sagittarius A* is highly variable at both X-ray and infrared (IR) wavelengths. Observations over the last ∼20 yr have revealed X-ray flares that rise above a quiescent thermal background about once per day, while faint X-ray flares from Sgr A* are undetectable below the constant thermal emission.

Breaking the Radio - Gamma-Ray Connection in Arp 220 [PDF]
, 2019 Recent analyses of the gamma-ray spectrum from the ultra-luminous infrared galaxy Arp 220 have revealed a discrepancy in the cosmic ray energy injection rates derived from the gamma-rays versus the radio emission. While the observed radio emission is consistent with the star formation rate inferred from infrared observations, a significantly higher ...
