THE INFRARED–GAMMA-RAY CONNECTION: A WISE VIEW OF THE EXTRAGALACTIC GAMMA-RAY SKY [PDF]
The Astrophysical Journal, 2016 ABSTRACT Using data from the Wide-field Infrared Survey Explorer (WISE) all-sky survey, we discovered that the nonthermal infrared (IR) emission of blazars, the largest known population of extragalactic γ-ray sources, has peculiar spectral properties.

Discovery of GeV emission from the direction of the luminous infrared galaxy NGC 2146 [PDF]
, 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 ...

First detection of GeV emission from an ultraluminous infrared galaxy: Arp 220 as seen with the Fermi Large Area Telescope [PDF]
, 2016 Cosmic rays (CRs) in starburst galaxies produce high energy gamma-rays by colliding with the dense interstellar medium (ISM). Arp 220 is the nearest ultra luminous infrared galaxy (ULIRG) that has star-formation at extreme levels, so it has long been ...

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

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.

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.

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.

How Infrared Radiation Was Discovered—Range of This Discovery and Detailed, Unknown Information
Applied Sciences, 2021 The reason for writing this article is that the details and mainly the scope of the fundamental discovery of infrared radiation are not widely known, and different accounts of this story are found in the literature.
